You are charged only if the goal is reached by 2026-09-20. In this prototype no payment is connected — only the reservation is recorded.

Pick a reward

¥3,500 Early-access play — One participation kit for the preview week before public launch. ¥6,000 Early access for two — Two kits, with priority booking for late-night slots.

Name (shown publicly — a pseudonym is fine) This appears in the backer list. "Anonymous" is fine.

Email (for contact only) Used only to tell you the outcome. Never shown publicly.

A short note (optional, up to 300 characters)

No money moves now. If the goal isn't reached, this reservation simply expires.
