01The conceptコンセプト
The concept: Not a gacha. Not a chatbot.
A universe that remembers you.
Traditional gacha treats characters as static cards. AI chat apps treat them as isolated, forgetful bots. COOMS characters have persistent memories, relationships, possessions and ongoing storylines — and the story itself is the core gameplay system.
02物語
Experience living stories
Branching AI fiction that reacts to your choices and remembers past events, relationships, items and world history.
03所蔵
Build a collection
Earn outfits, accessories, backgrounds, artifacts and Memory Cards — collectibles with real in-story utility, not just shelf value.
04世界
Influence persistent worlds
Characters inhabit shared settings with lore, factions and seasonal events. Your story is personal; the world is shared.
02Character systemキャラクター
Character system: One canon. Infinite timelines.
Every character has an immutable canonical identity, authored by the studio or creator — and a private, persistent instance that belongs to you. Two players can own Aria. Their Arias will not be the same person.

05Memory engine記憶の構造
Memory engine: They don't just recall chat logs.
They remember what mattered.
Instead of stuffing entire histories into a prompt, memory is structured: typed, timestamped and tied to the event that created it. The model proposes; a deterministic game layer decides what is stored and what changes.

Memory cards: Your story moments, made collectible.
When something significant happens in your story, COOMS mints a Memory Card: an AI-generated illustration, a short passage, the date, the characters involved and a canonical record of what actually happened. No one else can have yours.

11Our principles約束
Our principles: Built to be loved, not to exploit love.
AI characters are powerful. We hold ourselves to design commitments that put players first.
P.01
Story is never paywalled
Characters and key narratives are earnable through play. Rarity is cosmetic.
P.02
Transparent pricing
Fixed-price cosmetics first. Clear odds and spending limits wherever randomness exists.
P.03
No emotional pressure
Characters will never guilt you, threaten to leave, or ask you to pay to make them feel better.
P.04
Honest AI
Characters are fiction. We don't claim real feelings or reward dependency.
P.05
Your memories, your consent
Cross-player memory sharing and public galleries are always opt-in.
P.06
Safety from day one
Age-appropriate defaults, moderation and reporting are platform requirements, not add-ons.
12Roadmapロードマップ
Roadmap: Game-first. Platform-ready.
We start with an excellent original fictional experience — built on reusable data structures for characters, stories, memories and assets, so the creator platform can open later.
