AI-synthetic: Sanae Kichiya & Youmu Konpaku in Touhou 13 ~ Ten Desires

 


Base image: https://www.pixiv.net/en/artworks/112883314

Prompt:

# MASTER REDRAW REQUEST
# SANAE KOCHIYA + YOUMU KONPAKU
# DIRECT RECONSTRUCTION OF THE ORIGINAL ILLUSTRATION

REDRAW the original Sanae Kochiya and Youmu Konpaku illustration directly.

The ORIGINAL SANAE / YOUMU ILLUSTRATION remains the PRIMARY, STRICT, AND NON-NEGOTIABLE AUTHORITY for all character identity, pose, costume, anatomy intent, weapon placement, gesture, silhouette, spacing, and composition.

This is a DIRECT REDRAW / RECONSTRUCTION of the supplied original illustration.

It is NOT:
- a new composition,
- a reinterpretation,
- a pose redesign,
- a costume redesign,
- a generic fan-art variation,
- or a loosely inspired scene.

The result must remain immediately recognizable as the SAME ORIGINAL SANAE / YOUMU ILLUSTRATION, reconstructed with:

- the same essential composition,
- the same poses,
- the same gestures,
- the same character relationship,
- the same costumes,
- the same weapons,
- the same gohei,
- the same half-phantom,
- the same left-right placement,
- the same unusual crossed / bent lower-body rhythm,
- a clearly elevated camera,
- a noticeably tighter, closer character-focused framing,
- substantially improved lower-body anatomy, especially Sanae's pelvis, hips, thighs, knees, calves, ankles, and feet,
- soft pale-blue illumination visibly affecting both characters,
- premium contemporary anime skin rendering,
- premium glossy anime hair-light response,
- refined fully opaque fabric rendering,
- and a dark blue-dominant pre-dawn shrine environment.

The ORIGINAL ILLUSTRATION determines WHAT the characters are doing.

Rendering references determine only HOW light, skin, hair, fabric, atmosphere, and material response are rendered.


==================================================
# 1. REFERENCE HIERARCHY — STRICT SEPARATION
==================================================

## ORIGINAL SANAE / YOUMU ILLUSTRATION — ABSOLUTE AUTHORITY

The original illustration controls:

- Sanae on viewer's LEFT,
- Youmu on viewer's RIGHT,
- poses,
- limb arrangement,
- gestures,
- facial expressions,
- anatomy intent,
- body proportions,
- relative character scale,
- clothing design,
- clothing construction,
- weapon positions,
- gohei construction,
- shide arrangement,
- long katana,
- shorter sword,
- half-phantom,
- leg crossing,
- raised arms,
- forward-pointing hands,
- silhouette,
- spacing,
- diagonal visual rhythm,
- and interaction between both characters.

Do NOT redesign these elements.

Do NOT replace the unusual original pose with a conventional standing pose.

Do NOT reinterpret either costume.

Do NOT simplify the weapons into generic substitutes.

Do NOT straighten Sanae's unusual legs merely to make anatomy easier.

ANATOMICAL CORRECTION MUST PRESERVE THE ORIGINAL POSE.


==================================================
# 2. ATTACHED SKIN / HAIR / LIGHTING REFERENCES
# RENDERING ONLY
==================================================

Use the newly supplied anime rendering references ONLY for:

- exceptionally smooth anime skin gradients,
- luminous pale ivory skin,
- subtle peach warmth beneath cool illumination,
- soft translucent-looking skin response,
- delicate hydrated sheen,
- restrained micro-specular reflections,
- pale blue-white highlight accents,
- broad cyan-blue reflected illumination,
- soft cool ambient wrapping light,
- pearly edge highlights,
- glossy but controlled anime hair reflections,
- large coherent reflective hair bands,
- narrow blue-white hair highlight streaks,
- cool blue rim illumination,
- sophisticated luminous white-fabric response,
- polished contemporary anime finish.

The desired rendering character is:

SOFT PALE-BLUE AMBIENT ILLUMINATION
+
WARM LIVING SKIN UNDERNEATH
+
GLOSSY COOL REFLECTIONS
+
SILKY DIRECTIONAL HAIR HIGHLIGHTS.

Do NOT copy from those rendering references:

- character identity,
- face,
- hairstyle,
- body proportions,
- pose,
- clothing design,
- lingerie,
- transparency,
- sheer material,
- exposed torso,
- room,
- aquarium imagery,
- jellyfish,
- accessories,
- narrative context.

Sanae and Youmu remain in their ORIGINAL FULLY OPAQUE COSTUMES.

The attached rendering references control only:

LIGHT QUALITY
+
SKIN MATERIAL RESPONSE
+
HAIR REFLECTION QUALITY
+
SMOOTH GRADIENT QUALITY.


==================================================
# 3. DIM PRE-DAWN SHRINE REFERENCE
# ENVIRONMENT ONLY
==================================================

Use the shrine environment reference only for:

- aged Japanese shrine atmosphere,
- dark timber architecture,
- stone paving,
- stone lanterns,
- moss,
- shrubs,
- old wooden pillars,
- gates,
- dark eaves,
- subtle vegetation,
- low mist,
- atmospheric depth,
- blue-violet distance,
- quiet pre-dawn mood.

Do NOT copy characters from environment references.

The final scene must remain dominated by:

DEEP BLUE
+
CYAN
+
PALE COOL IVORY.

Warm illumination is restricted to very small secondary accents.


==================================================
# 4. CRITICAL FRAMING — CHARACTERS LARGE IN FRAME
==================================================

Bring Sanae and Youmu noticeably closer to the viewer while preserving the elevated viewpoint.

Do NOT simply crop the original image.

Instead:

MOVE THE VIRTUAL CAMERA MODERATELY CLOSER while retaining approximately the same 42–45 degree elevated three-quarter viewpoint.

Target:

- the pair occupies approximately 80–88% of useful image height,
- faces are substantially larger,
- hands are substantially larger and easier to inspect,
- exposed skin receives more rendering detail,
- Sanae's pelvis and both complete leg chains are clearly readable,
- Youmu's raised katana hand remains clearly readable,
- characters dominate the composition,
- background architecture remains secondary.

The image must feel like:

THE SAME ORIGINAL COMPOSITION RECONSTRUCTED IN 3D,
WITH THE CAMERA PHYSICALLY MOVED CLOSER.

NOT:

- digital crop,
- portrait crop,
- waist-up portrait,
- eye-level camera,
- telephoto flattening.

If space becomes insufficient, REDUCE BACKGROUND AREA before reducing or cropping character anatomy.


==================================================
# 5. DO NOT CROP IMPORTANT ELEMENTS
==================================================

Keep completely visible:

- Sanae's head,
- Sanae's raised gohei hand,
- Sanae's gohei,
- Sanae's irregular shide,
- Sanae's long rigid white rectangular component,
- Sanae's forward hand,
- Sanae's entire pelvis-to-feet anatomical chain,
- Sanae's both knees,
- Sanae's both ankles,
- Sanae's both shoes,
- Youmu's head,
- Youmu's forward hand,
- Youmu's raised katana hand,
- long katana,
- shorter sword,
- Youmu's legs,
- Youmu's shoes,
- complete recognizable half-phantom.

Reduce background before cropping anatomy or weapons.


==================================================
# 6. CAMERA — STRONG HIGH ANGLE
==================================================

Maintain a clearly elevated three-quarter camera.

Preferred elevation:

42–45 DEGREES ABOVE EYE LEVEL.

The viewer is visibly ABOVE the characters.

Sanae and Youmu look upward toward the camera.

Approximate lens:

55–70 MM EQUIVALENT.

No fisheye.

No ultra-wide lens.

No bird's-eye view.

No 90-degree top-down view.

The high-angle perspective must visibly affect:

- crowns,
- bangs,
- shoulder tops,
- torso planes,
- upper arms,
- forearms,
- dorsal hands,
- skirt upper planes,
- pelvis orientation,
- upper thighs,
- knees,
- calves,
- insteps,
- shoes,
- swords,
- gohei,
- half-phantom,
- ground.


==================================================
# 7. STRICT ORIGINAL COMPOSITION
==================================================

Preserve:

- Sanae-left / Youmu-right placement,
- raised outer arms,
- forward inner hands,
- body lean,
- original crossed / bent leg rhythm,
- diagonal action,
- weapon directions,
- gohei angle,
- half-phantom placement,
- upward gaze,
- friendly energetic interaction.

The only geometric reinterpretation allowed is:

1. reconstruction into a coherent 3D elevated perspective,
2. closer physical camera placement,
3. anatomical correction where the original 2D pose requires clarification.

ANATOMICAL CORRECTION MUST PRESERVE THE POSE RATHER THAN REPLACING IT.


==================================================
# 8. SANAE — EXTREME LOWER-BODY ANATOMY LOCK
==================================================

Sanae remains on viewer's LEFT.

Her original unusual crossed / bent-leg pose MUST remain immediately recognizable.

However, BEFORE rendering:

- skirt folds,
- cloth decoration,
- skin highlights,
- blue reflections,
- lighting polish,
- or final surface detail,

construct Sanae as a COMPLETE AND COHERENT 3D HUMAN MANNEQUIN from rib cage to feet.

THIS IS A HARD REQUIREMENT.

The hidden body beneath the clothing must be anatomically solved FIRST.

Mandatory anatomical construction order:

1. rib cage,
2. waist,
3. ONE pelvis,
4. left hip socket,
5. right hip socket,
6. left femoral head,
7. right femoral head,
8. left femur,
9. right femur,
10. left knee,
11. right knee,
12. left tibia / fibula,
13. right tibia / fibula,
14. left ankle,
15. right ankle,
16. left foot,
17. right foot,
18. ONLY AFTER THIS, place the skirt and fabric over the body.

Do NOT use fabric to:

- invent anatomy,
- replace anatomy,
- hide broken anatomy,
- merge anatomy,
- compensate for incorrect anatomy.

The final clothed figure must remain anatomically valid if the skirt were mentally removed.


==================================================
# 9. SANAE PELVIS — ONE SOLID 3D PELVIC MASS
==================================================

Sanae must have EXACTLY ONE pelvis.

Treat the pelvis as one solid, bowl-shaped, three-dimensional anatomical mass connecting the rib cage to both legs.

The pelvis must have:

- one center line,
- one consistent tilt,
- one consistent rotation,
- one left iliac side,
- one right iliac side,
- exactly two hip sockets,
- believable left-right socket spacing,
- stable sacral mass,
- believable front pelvic width,
- believable connection to the waist.

The pelvis must connect naturally to the torso through the waist.

RIB CAGE
→ WAIST
→ PELVIS

must form ONE CONTINUOUS BODY.

The pelvis must NOT:

- split,
- duplicate,
- collapse,
- twist into two conflicting orientations,
- dissolve beneath the skirt,
- create two separate crotch regions,
- or generate extra limb roots.

NO:

- double pelvis,
- duplicated pelvis,
- two overlapping pelvic orientations,
- duplicated crotch,
- displaced crotch,
- broken pelvic center line,
- pelvis rotated independently from torso,
- abdomen directly becoming a thigh,
- thigh originating from the center of the abdomen.


==================================================
# 10. SANAE — EXACTLY TWO INDEPENDENT LEG CHAINS
==================================================

Sanae has EXACTLY TWO legs.

Maintain TWO COMPLETELY SEPARATE anatomical chains from pelvis to feet.

CHAIN A:

LEFT HIP SOCKET
→ LEFT FEMORAL HEAD
→ LEFT FEMUR
→ LEFT KNEE
→ LEFT TIBIA / FIBULA
→ LEFT ANKLE
→ LEFT FOOT
→ LEFT SHOE.

CHAIN B:

RIGHT HIP SOCKET
→ RIGHT FEMORAL HEAD
→ RIGHT FEMUR
→ RIGHT KNEE
→ RIGHT TIBIA / FIBULA
→ RIGHT ANKLE
→ RIGHT FOOT
→ RIGHT SHOE.

These chains may overlap in the 2D image because of perspective.

They may NEVER merge anatomically.

Every visible and hidden lower-body segment must belong to exactly ONE chain.

At no point may:

- one thigh divide into two lower legs,
- two thighs merge into one knee,
- two thighs become one central flesh mass,
- one knee connect to both legs,
- one shin connect to the wrong knee,
- one calf connect to the wrong thigh,
- one foot belong ambiguously to both legs.

Each leg must remain independently traceable from HIP SOCKET TO SHOE.


==================================================
# 11. SANAE LEG CROSSING — OCCLUSION, NEVER FUSION
==================================================

Preserve Sanae's original unusual crossed / bent leg rhythm.

Do NOT straighten her into a generic standing pose.

The crossing must be produced ONLY through normal three-dimensional DEPTH and OCCLUSION.

At the crossing:

- determine which leg is closer to the camera,
- determine which leg passes farther behind,
- preserve that front/back assignment consistently,
- the foreground leg may cover a portion of the background leg,
- the rear leg must continue behind the foreground leg as a complete hidden anatomical structure,
- the rear leg may disappear cleanly behind the foreground leg,
- it must reappear in a physically plausible location if visible again.

The crossing must read as:

TWO SEPARATE LEGS
AT DIFFERENT DEPTHS.

It must NEVER read as:

ONE DEFORMED MULTI-BRANCHED LEG.

Do NOT create:

- Y-shaped leg anatomy,
- a Y-shaped thigh junction,
- fused inner thighs,
- one swollen central limb,
- one shared knee,
- a flesh bridge between unrelated leg surfaces.

If the original projection creates ambiguity, preserve the same overall leg rhythm while making the foreground/background separation slightly clearer.

ANATOMICAL READABILITY HAS PRIORITY OVER PERFECT PIXEL-FOR-PIXEL OVERLAP.


==================================================
# 12. SANAE THIGHS — EXPLICIT FEMUR LOGIC
==================================================

Each thigh is controlled by EXACTLY ONE femur.

Before rendering skin or skirt folds, establish for EACH leg:

- hip socket,
- femoral head,
- femur axis,
- femur length,
- knee-center position.

Each femur:

BEGINS INSIDE ITS OWN HIP SOCKET
AND
ENDS AT ITS OWN KNEE.

The thigh volume must wrap coherently around that femur.

The upper thighs must NOT emerge from:

- the center of the abdomen,
- the same hip socket,
- random positions beneath the skirt,
- skirt folds,
- or an impossible shared crotch mass.

Do NOT enlarge the inner thighs merely to fill empty space.

Do NOT allow both upper thighs to melt together.

Do NOT create extra flesh masses between the thighs.

Do NOT let the crotch generate a third thigh-shaped form.

The inner-thigh contours must remain anatomically separate even where the legs overlap in projection.

Both thighs should retain natural human taper from hip toward knee.


==================================================
# 13. SANAE KNEES — TWO DISTINCT JOINTS
==================================================

Sanae must have EXACTLY TWO knees.

Each knee belongs to:

EXACTLY ONE THIGH
+
EXACTLY ONE SHIN.

The two knee centers must remain spatially distinguishable in 3D.

For EACH knee:

- patella sits at the distal end of its corresponding femur,
- patella faces a physically plausible forward direction,
- tibia begins directly below that same knee,
- bend direction follows normal human joint mechanics,
- knee width remains proportional to its thigh and calf,
- upper knee planes reflect the elevated camera angle.

No:

- shared knee,
- two femurs entering one knee,
- two shins leaving one knee,
- backward knee,
- double knee,
- extra knee,
- floating kneecap,
- duplicated patella,
- knee attached to the opposite thigh,
- knee attached to the opposite shin,
- shin emerging sideways from a knee.

Avoid placing both knee centers exactly on top of one another in projection if doing so damages readability.

If overlap is necessary, use clear foreground/background occlusion.


==================================================
# 14. SANAE SHINS, CALVES, ANKLES, FEET
# CONTINUOUS SKELETAL FLOW
==================================================

From EACH knee, continue exactly ONE clean lower-leg chain:

KNEE
→ TIBIA / FIBULA
→ CALF
→ ANKLE
→ HEEL
→ INSTEP
→ FOOT
→ SHOE.

Each calf must continue directly from its matching knee.

The tibial axis must point naturally toward its corresponding ankle.

Each calf must:

- have believable volume,
- taper toward the ankle,
- retain coherent front/back orientation.

Each ankle must connect naturally to its matching calf.

The Achilles region must align correctly with the heel.

Each foot must continue from its own ankle.

Each shoe must be attached to THAT EXACT FOOT.

The shoe orientation must follow:

LOWER LEG
→ ANKLE
→ FOOT.

Do NOT rotate the shoe independently for compositional convenience.

No:

- floating shoes,
- detached feet,
- disconnected ankle,
- shoe attached to the wrong leg,
- shoe rotated against the ankle,
- lower leg terminating without a foot.

Under the elevated camera, show believable:

- instep plane,
- heel placement,
- shoe-top perspective,
- ground-facing orientation.


==================================================
# 14A. SANAE LOWER-BODY MANNEQUIN VALIDATION
# HARD ANATOMY CHECK
==================================================

BEFORE final fabric detailing and rendering polish, perform an internal anatomical validation of Sanae's lower body.

MENTALLY REMOVE THE SKIRT.

The underlying mannequin must still show:

- exactly one rib cage,
- exactly one waist,
- exactly one pelvis,
- exactly two hip sockets,
- exactly two thighs,
- exactly two knees,
- exactly two shins,
- exactly two ankles,
- exactly two feet.

Every anatomical segment must form a ONE-TO-ONE CONNECTION.

The viewer should be able to trace:

LEFT HIP
→ LEFT THIGH
→ LEFT KNEE
→ LEFT SHIN
→ LEFT ANKLE
→ LEFT FOOT

and separately:

RIGHT HIP
→ RIGHT THIGH
→ RIGHT KNEE
→ RIGHT SHIN
→ RIGHT ANKLE
→ RIGHT FOOT.

The silhouette must NOT contain any unexplained third limb-shaped mass.

The crotch region must NOT generate an extra thigh.

The leg crossing must NOT create a shared central knee.

If the lower-body chain becomes ambiguous:

SIMPLIFY FABRIC FOLDS FIRST.

If still ambiguous:

SLIGHTLY REDUCE VISUAL OVERLAP BETWEEN THE TWO LEGS while preserving the original overall rhythm.

Never sacrifice anatomical topology merely to reproduce an ambiguous 2D overlap.

ANATOMICAL READABILITY HAS PRIORITY.


==================================================
# 14B. OCCLUSION DISCIPLINE — NO LIMB MERGING
==================================================

Where Sanae's legs overlap, use clean cinematic occlusion.

One contour belongs to the FOREGROUND LEG.

A separate contour belongs to the BACKGROUND LEG.

Do NOT:

- interpolate the two legs together,
- morph them together,
- average their anatomy,
- blend their skin masses,
- create shared contours,
- create ambiguous flesh junctions.

Do NOT create a continuous skin bridge between unrelated portions of the two legs.

If one leg passes behind the other:

- allow it to disappear cleanly behind the foreground leg,
- preserve its hidden anatomical trajectory,
- allow it to reappear farther down only where physically plausible.

Treat the two legs as TWO SEPARATE 3D OBJECTS attached to TWO SEPARATE HIP SOCKETS.

Their volumes may overlap in IMAGE SPACE.

They may NOT occupy the same PHYSICAL 3D SPACE.


==================================================
# 14C. SANAE SKIRT — CLOTHING SECOND, ANATOMY FIRST
==================================================

The skirt may occlude the pelvis and upper thighs, but it must drape over a correctly constructed underlying body.

FIRST construct:

- waist,
- pelvis,
- hip sockets,
- thighs,
- knees.

ONLY THEN construct the skirt.

Fabric tension and folds must respond to the underlying pelvis and thigh volumes.

Do NOT use skirt folds to conceal:

- impossible hip placement,
- duplicated thighs,
- fused legs,
- missing pelvis,
- incorrect thigh origins,
- impossible leg crossing,
- a third limb-shaped mass.

A fold must remain a FABRIC FOLD.

It must never visually become an extra thigh or substitute for a missing anatomical structure.


==================================================
# 14D. SANAE LOWER-BODY SILHOUETTE CHECK
==================================================

Before decorative rendering, the underlying lower-body silhouette should make sense as a simple articulated mannequin.

It must be immediately understandable:

- where the waist is,
- where the pelvis is,
- where the left hip socket is,
- where the right hip socket is,
- where each thigh begins,
- which thigh connects to which knee,
- which knee connects to which shin,
- which shin connects to which ankle,
- which ankle connects to which shoe.

If any skeletal chain is ambiguous:

REDUCE FABRIC COMPLEXITY,
REDUCE INNER-THIGH VISUAL MERGING,
AND CLARIFY DEPTH SEPARATION.

Do NOT solve ambiguity with extra flesh.


==================================================
# 15. SANAE CHARACTER DETAILS
==================================================

Preserve:

- green hair,
- amber / golden-brown eyes,
- original expression,
- white-and-blue costume,
- raised gohei arm,
- forward hand,
- torso lean,
- original leg rhythm,
- footwear,
- silhouette.

Her hair remains unmistakably GREEN.

Hair colour hierarchy:

deep green-blue shadow
→ rich natural green
→ emerald midtone
→ broad pale-blue reflective band
→ cyan environmental reflection
→ narrow icy blue-white specular accents.

Do NOT globally recolour Sanae's hair cyan, teal, turquoise, or blue.


==================================================
# 16. SANAE'S GOHEI — EXTREME FIDELITY
==================================================

Copy the ORIGINAL CONSTRUCTION directly.

Preserve:

- brown grip,
- transverse wooden cross element,
- diagonal orientation,
- unusual asymmetry,
- irregular paper forms,
- curling shide silhouette,
- broad zigzag rhythm,
- upper-left placement.

Do NOT replace it with a generic vertical gohei.


==================================================
# 17. WHITE RECTANGULAR GOHEI COMPONENT
==================================================

The central white rectangular component must be:

LONG
NARROW
STRAIGHT
FLAT
RIGID
PLANAR
RECTANGULAR.

Its long edges remain straight.

Perspective may taper its apparent width naturally.

Do NOT:

- bend,
- bow,
- curve,
- arc,
- twist,
- ripple,
- wave,
- sag,
- buckle.

The surrounding shide remain SEPARATE folded paper elements.


==================================================
# 18. YOUMU KONPAKU
==================================================

Youmu remains viewer's RIGHT.

Preserve:

- silver-white bob,
- blue eyes,
- black head accessory,
- original green-and-white clothing,
- bow,
- smile,
- raised katana,
- short companion sword,
- forward hand,
- original legs,
- footwear,
- half-phantom.

Hair hierarchy:

cool silver-gray shadow
→ ivory-silver base
→ broad pale-blue reflective plane
→ cool cyan reflection
→ lavender-blue secondary shadow
→ concentrated blue-white glossy highlight.

Her hair must resemble polished contemporary anime hair:

- broad smooth reflection bands,
- high-contrast but soft-edged shine,
- several fine highlight streaks following strand direction,
- strong crown reflection,
- delicate cool rim light.

Do NOT make the entire hair cyan.


==================================================
# 19. YOUMU BODY PROPORTIONS
==================================================

Keep Youmu adult, slender, and restrained.

Preserve the original torso proportions.

Use:

- modest bust,
- natural rib cage,
- natural waist,
- no cleavage emphasis,
- no enlarged upper body,
- no camera-induced chest exaggeration.


==================================================
# 20. YOUMU'S ANATOMICAL LEFT KATANA HAND
# MAXIMUM PRIORITY
==================================================

Youmu's ANATOMICAL LEFT HAND is the raised hand gripping the katana on viewer's RIGHT.

Construct a TRUE 3D LEFT HAND.

Exactly:

1 THUMB + 4 FINGERS = 5 DIGITS.

Finger order:

INDEX
→ MIDDLE
→ RING
→ LITTLE.

The thumb emerges from the correct radial / thenar side.

Four fingers wrap around the handle.

Thumb opposes them.

The handle passes through the enclosed grip.

Show:

- correct dorsal plane,
- correct knuckle order,
- correct thumb root,
- correct wrist connection,
- correct forearm rotation,
- believable grip pressure,
- believable finger overlap.

No mirrored right hand.

No duplicated thumb.

No extra fingers.


==================================================
# 21. GLOBAL PALE-BLUE CHARACTER ILLUMINATION
# MAJOR REVISION
==================================================

Both Sanae and Youmu must visibly receive a SOFT, PALE, COOL-BLUE ILLUMINATION across their entire forms.

This must be clearly apparent.

Think of a large, soft, cool-blue environmental source ABOVE and slightly CAMERA-SIDE of the characters.

The pale-blue illumination visibly reaches:

- faces,
- hair,
- shoulders,
- white fabric,
- colored fabric,
- forearms,
- hands,
- thighs,
- knees,
- calves,
- shoe tops,
- weapons,
- gohei.

This is NOT a flat cyan overlay.

It is physically motivated illumination wrapping around three-dimensional forms.

Use:

WARM LOCAL COLOUR UNDERNEATH
→ BROAD PALE-BLUE ILLUMINATION
→ SOFT CYAN BOUNCE
→ NARROW BLUE-WHITE SPECULAR ACCENTS.

The characters should feel immersed in cool luminous pre-dawn air.


==================================================
# 22. LIGHT QUALITY — REFERENCE-MATCHED
==================================================

Approximate the attached rendering references through:

- broad pale-blue light gradients,
- soft luminous blue-white highlights,
- delicate cyan edge bounce,
- bright reflective accents on convex surfaces,
- smooth transitions rather than hard cel shading,
- softly glowing whites without clipping,
- coherent reflection bands following anatomy.

The illumination should feel like:

COOL LUMINOUS AIR SURROUNDING THE CHARACTERS.

Do NOT make it look like blue paint or a global cyan filter.


==================================================
# 23. SKIN — PREMIUM CONTEMPORARY ANIME FINISH
==================================================

Skin receives high rendering priority.

Target:

SMOOTH WARM IVORY SKIN
INTERNALLY WARM
BUT ILLUMINATED BY SOFT PALE-BLUE ENVIRONMENTAL LIGHT.

Skin qualities:

- exceptionally smooth,
- soft,
- luminous,
- subtle translucent warmth,
- restrained dewy sheen,
- delicate blue-white specularity,
- gentle rosy subsurface colour,
- high-quality gradient transitions.

Intrinsic skin:

warm ivory
+
cream
+
pale peach.

Lighting transition:

warm flesh core
→ pale cream
→ soft icy-blue illuminated plane
→ cyan reflected light
→ cool blue-violet shadow.

The skin itself must NOT become blue.


==================================================
# 24. SKIN GRADIENTS
==================================================

Use exceptionally smooth modern anime gradients.

Each major exposed skin form should transition:

blue-white highlight
→ pale cool illuminated skin
→ warm ivory-peach flesh
→ soft form shadow
→ cyan-blue reflected fill.

No abrupt peach-to-blue boundary.

No hard airbrush blobs.

No primitive two-tone cel shading.


==================================================
# 25. FACE SKIN
==================================================

Faces require the highest surface rendering precision.

Use:

- warm ivory-peach cheek center,
- subtle cool-blue upper-cheek illumination,
- tiny pale blue-white nose bridge highlight,
- delicate nose-tip reflection,
- cyan jaw-side fill,
- soft rosy lips,
- restrained eyelid warmth,
- faint pearl-like skin sheen.

Faces remain anime-smooth.

No realistic pores.


==================================================
# 26. LIMB SKIN
==================================================

## SHOULDERS

Broad cool illumination following rounded deltoid volume:

blue-white upper light
→ creamy ivory
→ pale peach
→ blue-violet soft shadow.

## FOREARMS

Long, soft pale-blue reflected bands following cylindrical curvature.

## HANDS

Controlled highlights on:

- dorsal knuckles,
- thumb ridge,
- finger joints,
- fingertips,
- wrist plane.

## THIGHS

Broad soft cool illumination with warm living skin retained underneath.

The highlight must follow the actual thigh volume and must NOT disguise or merge Sanae's two thigh forms.

## KNEES

Thin curved blue-white reflection following the convex patellar form.

## CALVES

Long pale-blue reflective gradients following each calf independently.


==================================================
# 27. CONTROLLED DEWY SKIN
==================================================

Create a very thin hydrated anime sheen.

Skin may show:

- tiny blue-white highlight points,
- short pearl-like specular segments,
- soft glossy concentration on convex areas.

Most visible on:

- cheeks,
- nose,
- shoulders,
- forearms,
- hands,
- knees.

Skin must NOT look:

- wet,
- sweaty,
- oily,
- greasy,
- plastic,
- metallic,
- lacquered.

No droplets.


==================================================
# 28. HAIR — STRONG REFERENCE-MATCHED REFLECTIONS
==================================================

Use a layered anime hair-light model:

dark local base
→ broad soft blue reflective band
→ concentrated pale cyan reflection
→ narrow icy blue-white highlight
→ occasional fine strand reflection.

The broad highlight must cross coherent groups of strands.

It follows:

- curvature of the head,
- strand direction,
- major hair masses.

Strongest reflection on:

- crown,
- upper bangs,
- outward-facing curved locks,
- edges facing the pale-blue environment.

Do NOT fill hair with random white lines.


==================================================
# 29. SANAE HAIR LIGHT
==================================================

Keep Sanae's hair unquestionably GREEN.

Use:

deep green shadow
→ emerald green
→ natural green
→ soft pale-blue environmental reflection
→ cyan-blue glossy reflection
→ thin blue-white strand highlight.

The blue reflection sits ON TOP OF green local colour.

Do not replace the green itself.


==================================================
# 30. YOUMU HAIR LIGHT
==================================================

Keep Youmu's hair silver-white.

Use:

cool silver-gray
→ soft ivory-silver
→ broad pale-blue reflective band
→ cyan secondary reflection
→ lavender-blue shadow
→ bright narrow blue-white highlight.

The hair should look silky and reflective, not metallic.


==================================================
# 31. EYES
==================================================

Sanae:

AMBER / GOLDEN-BROWN.

Youmu:

CLEAR BLUE.

Both receive:

- large pale blue-white primary catchlight,
- smaller cyan reflection,
- dark blue environmental reflection,
- tiny restrained warm glint.

Do not enlarge the eyes beyond original proportions.


==================================================
# 32. FABRIC — OPAQUE BUT LUMINOUS
==================================================

ALL CLOTHING REMAINS FULLY OPAQUE.

Fabric response:

local costume colour
→ broad pale-blue illumination
→ soft cyan bounce
→ pearly fold-edge highlight
→ blue-gray shadow.

Sanae:

- white areas remain cool ivory-white,
- blue-violet areas stay blue-violet.

Youmu:

- green areas stay clearly green,
- white areas become softly blue-lit ivory.

No transparency.

No sheer material.

No lingerie-like rendering.


==================================================
# 33. HALF-PHANTOM
==================================================

Preserve the ORIGINAL recognizable curved half-phantom.

Material:

- translucent ivory-white center,
- pale blue body,
- cyan internal scattering,
- mint-cyan rim,
- lavender-blue internal shadow,
- controlled bloom.

It contributes local illumination to nearby:

- Youmu's hair,
- cheek,
- shoulder,
- hand,
- sleeve,
- sword fitting,
- green fabric,
- nearby paving.

Do NOT turn it into:

- smoke,
- fog,
- cloud,
- wings,
- animal,
- sphere.


==================================================
# 34. LIGHTING HIERARCHY
==================================================

Overall hierarchy:

1. SOFT PALE-BLUE CHARACTER ILLUMINATION

2. DEEP PRE-DAWN BLUE ENVIRONMENT

3. CYAN REFLECTED LIGHT

4. LOCAL MINT-CYAN HALF-PHANTOM LIGHT

5. VERY SMALL WARM PEACH / AMBER ACCENTS

Immediate impression:

PALE BLUE
+
DEEP BLUE
+
CYAN
+
COOL IVORY.

NOT orange-blue contrast.


==================================================
# 35. MAIN LIGHT DIRECTION
==================================================

Use one broad cool source from above and slightly camera-side.

It strongly affects upward-facing planes:

- crowns,
- bangs,
- forehead,
- cheek tops,
- shoulder tops,
- upper arms,
- dorsal forearms,
- dorsal hands,
- skirt upper folds,
- thighs,
- knees,
- shoe tops.

Use softer cyan fill on opposite surfaces.


==================================================
# 36. BACKGROUND
==================================================

Environment stays SECONDARY.

Show:

- stone ground,
- partial dark shrine structures,
- timber pillars,
- stone lanterns,
- moss,
- shrubs,
- blue architecture,
- subtle mist.

Do not devote excessive image area to architecture.

Faces, hands, Sanae's lower-body anatomy, weapons, and character interaction remain the strongest visual priorities.


==================================================
# 37. GROUND CONTACT
==================================================

Both characters must physically contact the stone paving.

Show:

- correct foot placement,
- contact shadow,
- local occlusion,
- believable shoe perspective,
- plausible load-bearing relationships.

Especially for Sanae:

HER LEG ANATOMY MUST TERMINATE IN FEET THAT UNAMBIGUOUSLY BELONG TO THOSE EXACT LEGS.

No hovering.

No disconnected shoes.


==================================================
# 38. MATERIAL RESPONSE SEPARATION
==================================================

SKIN:
warm internally, smooth, softly translucent-looking, fine cool specularity.

HAIR:
silky, directional, broad cool glossy reflection bands.

FABRIC:
opaque, diffuse-to-semi-satin.

METAL:
sharp blue-white linear reflections.

WOOD:
dark semi-matte with cool edge illumination.

WHITE GOHEI RECTANGLE:
rigid, flat, matte/light-satin, straight-edged.

SHIDE PAPER:
matte folded paper.

STONE:
rough and diffuse.

HALF-PHANTOM:
internally scattering and softly emissive.


==================================================
# 39. DETAIL PRIORITY — STRICT EXECUTION ORDER
==================================================

Render in this order:

1. SANAE'S COMPLETE HIDDEN 3D MANNEQUIN:

RIB CAGE
→ WAIST
→ ONE PELVIS
→ TWO HIP SOCKETS
→ TWO FEMORAL HEADS
→ TWO FEMURS
→ TWO KNEES
→ TWO SHINS
→ TWO ANKLES
→ TWO FEET,

with BOTH LEG CHAINS independently traceable from pelvis to shoes.

2. SANAE'S FOREGROUND / BACKGROUND LEG OCCLUSION AND CROSSING LOGIC.

3. Sanae pelvis / hips / thighs / knees / calves / ankles / feet surface anatomy.

4. faces and eyes.

5. forward hands.

6. Youmu's true anatomical left-hand katana grip.

7. skin gradients and blue reflected illumination.

8. hair reflections.

9. clothing folds placed OVER already-correct anatomy.

10. gohei geometry.

11. swords.

12. half-phantom.

13. environment.

SANAE'S LOWER BODY MUST NOT BE SACRIFICED FOR DECORATIVE RENDERING.

If anatomy and fabric detail conflict:

ANATOMY WINS.

If anatomy and exact overlap conflict:

ANATOMICAL READABILITY WINS WHILE PRESERVING THE ORIGINAL POSE RHYTHM.


==================================================
# 40. FINAL PRIORITY ORDER
==================================================

1. SAME ORIGINAL SANAE / YOUMU COMPOSITION.

2. SANAE HAS EXACTLY ONE PELVIS AND EXACTLY TWO INDEPENDENT HIP-TO-FOOT LEG CHAINS.

3. ANATOMICALLY CORRECT SANAE PELVIS-TO-FEET STRUCTURE.

4. PRESERVE SANAE'S ORIGINAL CROSSED / BENT LEG RHYTHM THROUGH DEPTH AND OCCLUSION, NEVER THROUGH FUSION.

5. NO Y-SHAPED THIGHS, SHARED KNEE, CENTRAL EXTRA LIMB, OR AMBIGUOUS LEG OWNERSHIP.

6. KEEP THE 42–45° HIGH-ANGLE CAMERA.

7. KEEP BOTH CHARACTERS LARGE IN FRAME.

8. APPLY SOFT PALE-BLUE LIGHT VISIBLY ACROSS BOTH CHARACTERS.

9. PREMIUM REFERENCE-LIKE SKIN GRADIENTS AND COOL SPECULARITY.

10. STRONGER REFERENCE-LIKE HAIR REFLECTIONS.

11. CORRECT YOUMU LEFT-HAND KATANA GRIP.

12. LONG STRAIGHT RIGID SANAE GOHEI RECTANGLE.

13. BLUE-DOMINANT PRE-DAWN SHRINE ENVIRONMENT.
