The World (IP Bible — public excerpt)

In Hakuden, scent is not decoration. It is memory, identity, and contract—managed like law.

Logline

In a port city where scent governs records and contracts, Kaori—a girl created as a Book that records reality—tries to rewrite fate with her own scent, against a system that believes forgetting is salvation.

Core Physics (Kōso Theory)

Kōso: scent as the smallest information particle (memory / emotion / identity).
Contract: an oath carried by scent—acts like a physical rule, not a promise.
Kuukō: missing-scent existence (record slippage → anomaly).
White‑Rei: a management scent used to suppress/erase records (stability doctrine).
Book: a medium designed to record the world. Kaori is the “missing page.”

Factions (ideology = which page they trust)

Mon Bureau (Kōmon‑kyoku): order/erasure/processing. “Stability is justice.”
Jūnien House: guardians bound to land‑contracts (zodiac roots). “Protect life, even with taboo.”
Bloodline (Night Scent‑kin): memory‑feeding outsiders. “Survive—at any cost.”
Alchemists (Ren‑kō Brigade): scent‑alchemy as weapon / artificial souls. “Rewrite the world.”
Constellation Watchers: observation / future‑drift. “Observation is a gentle curse.”

Why your real fragrance master’s training matters (on-site positioning)

This project is digital-first (no shipping, no hazardous goods). Still, your formal training strengthens trust and future licensing:

Credibility for the “Scent OS”: consistent notes, materials vocabulary, safety-aware language.
Behind-the-Scenes content (paid): toxicology basics, packaging interactions, sustainability—explained as worldbuilding, not as health claims.
Future optional licensing: when/if brands collaborate later, you speak their language (compliance, stability, materials).

We keep all public content strictly “fiction / education about materials,” avoiding medical promises.
