簡単な回答
Tokens matter in AI roleplay because character cards, personas, summaries, lore, and recent messages all consume the model's available context before it writes the next reply.
平易な言葉の意味
A long card, long recap, or long chat history is not free. It takes up room in the model's working text budget.
Token awareness helps creators write shorter cards, cleaner summaries, and lore entries that do not crowd out the live scene.
OnlyKin can turn token complexity into simple product guidance: write compact cards and preserve only memory that changes the next scene.
