First Night Under Makima is a playable AI visual novel set in the world of Chainsaw Man. You are Denji — broke, newly fused with a chainsaw devil, and one phone call away from becoming useful. On your first Public Safety night, you share a cramped apartment with a blood fiend named Power, a sword-wielding hunter named Aki Hayakawa, and the woman who recruited you: Makima, whose smile never quite reaches her eyes.
Everything you say is written live by an AI storyteller. Every choice shifts three meters — Hunger, Control, and Bond — and every shift bends the night toward a different dawn. Feed the Hunger and stay alive. Obey the Control and earn Makima's favor. Build the Bond and hold your chaotic new household together.

Game Features
- Live LLM Narrative — Every scene, every reply, and every character — Denji, Makima, Power, and Aki Hayakawa — is written in real time by an LLM as you play. No two first nights under Makima unfold the same (deepseek-chat real-time narrative).
- Three Meters, One Night — Hunger, Control, and Bond tick up and down with every line you speak. The ending is not fixed — it is built from the appetite you feed, the leash you accept, and the family you keep.
- Free-Form Dialogue — Type anything: beg Power for the last toast, ask Aki about the Gun Devil, or stay silent while Makima waits. The AI reads your intent and answers in character.
- The Cast of Division 4 — Denji, Makima, Power, and Aki Hayakawa appear with original full-body sprites — cut out to transparent PNGs — over scene backgrounds drawn in the Chainsaw Man editorial style.
- Milestone Story Beats — The night advances through real story milestones: the cramped apartment, the rainy street mission, Power's chaos at breakfast, and the phone call from Makima that decides what Denji is for.
- Browser Playable — Runs directly in your browser, no download needed. Live LLM dialogue on every turn.

Stage 2: Game Design & Artgpt-image-2
AI designs the game from the atom cards: writes the story rules, designs the scene flow around Denji's first night under Makima, and generates all art — the rainy Tokyo title background, the apartment and rainy-street scene backgrounds, and the full-body character sprites. Each sprite was generated with a full-body sprite prompt on a pure white background, then background-removed to a transparent PNG via BiRefNet.
