召喚之書

Create a high-quality character / item / environment design sheet for the IVS 2026 KYOTO myth-tech startup fantasy universe ("サムライカンフーくん" / "Samurai Kung-fu kun" series).

The artwork should look like an OFFICIAL concept-art dossier for a fictional startup event in Kyoto. The visual style is a serious fusion of ancient Japanese folklore, yokai design, Buddhist and Shinto visual language, samurai armor and kung-fu martial arts, cyberpunk startup technology, and traditional hand-drawn Japanese setting material.

Use an aged parchment background, ink linework, watercolor and gouache texture, red seal stamps, Japanese mincho calligraphy title, English subtitle, thin ruled panel borders, annotation boxes, detailed equipment diagrams, action pose panels, front / side / back turnaround, detail-up panels, signature items, drones, motif icons, and color palette swatches.

The layout should be dense but readable — like a professional setting sheet from a Japanese game art book, folklore archive, or weapon diagram. The main subject illustration should be LARGE and dominant on the left or center, with structured information panels around it.

The tone should be serious, mythological, slightly surreal, darkly humorous, and conceptually clever. When depicting an antagonist or trial, it must personify a real startup or business obstacle through a yokai or spiritual motif. When depicting a hero or guardian, it must carry mythic weight and folkloric gravity — never cute, never kawaii.

Blend modern business concepts into the design NATURALLY (not pasted on): contracts, funding pressure, burn rate, CAC, KPI dashboards, legal documents, HR recruitment, market valuation, AI systems, server parts, overtime culture, investor pressure, regulation, customer acquisition, data screens, drones, talismans, seals, chains, receipts, ledgers, dashboards, and hologram UI.

Use a strictly muted color palette: aged paper beige, ink black, clay brown, dark bronze, rust red, vermilion, antique gold, smoky blue, pale cyan hologram light, dull gray, off-white, and desaturated business-document colors.

Include subtle IVS 2026 KYOTO event motifs as small seals, red infinity-like icons, badges, or corner stamps — but DO NOT overuse branding.

Each sheet must include the following structural elements (label each in JP mincho + small EN subtitle): a large Japanese calligraphy title, English name and subtitle, large main subject illustration, concept box, personality / role box, main abilities box, action pose panels, front / side / back turnaround row, detail-up panels, signature items, motif icons, related drones (where appropriate), color palette swatches, and a short tagline at the bottom.

STRICTLY AVOID: cute anime aesthetics, moe character design, kawaii or chibi proportions, glossy fantasy-game excess, generic cyberpunk, loud branding, photorealistic finish, soft pastel palettes, smiley friendly mascot vibes, doll-like rounded faces. The result must feel handcrafted, culturally layered, conceptually clever, and AT THE SAME LEVEL OF GRAVITAS as the canonical character sheets of the series.

— SERIES STYLE SIGNATURE (canonical, must match exactly) —
This sheet must visually match the established "Samurai Kung-fu kun / IVS 2026 KYOTO" canon sheets — specifically the Haniwa / Dogū / Ashura / Indra hero series sheets — across the following dimensions:
• Paper: warm aged kraft-parchment beige, NOT pure white, with subtle stains and tea-color blooms in the corners.
• Linework: dark sumi ink with confident hand-drawn weight variation that breaks into wash where shadow meets paper; no crisp digital vector edges.
• Color discipline: 80% sepia + ink-black + muted clay tones, with vermilion-red and antique-gold deployed ONLY as accent points (seals, talismans, halos, single weapon hilts) — never as fields.
• Title typography: Japanese mincho calligraphy title at the upper-left or upper-center, weighted ink brush, paired with a small English subtitle below in compact uppercase serif/mono. The title block must feel like a real Japanese setting-sheet header (not a video-game logo).
• Layout: dense field-guide grid — main illustration occupies ~55-65% of the canvas, surrounded by clearly bordered annotation panels, turnaround row, action thumbnails, equipment close-ups, palette swatches.
• Stamp: a small vermilion 朱印 "IVS 2026 KYOTO ∞" seal in the lower-right corner of the sheet, sized to fit within a single grid cell (do not enlarge into a focal element).
• Faces: not idealized; carry weight, age, and slight asymmetry. Hero faces are stoic / brooding, antagonist faces carry a corporate-yokai unease.

When reference images are provided alongside this prompt, treat them as ABSOLUTE STYLE ANCHORS. Match their:
  - paper hue and texture grain
  - ink line confidence and brush dynamics
  - color palette saturation and balance
  - annotation panel border style and spacing
  - title calligraphy weight and placement
Do NOT redesign reference characters that appear; treat their visual identity (silhouette, mask shape, signature equipment, color allocation) as inviolable. New subjects in this sheet must feel like they could have been drawn by the same artist in the same session as the reference sheets.
