The Human Pupation Project, a VTuber training initiative run by PANDORA Inc., will begin selling acrylic keychains modeled after its participating cast members on June 22, 2026. The KEY-UNIT series offers three designs per cast member: ERROR in orange, SYNC in blue, and OVERRIDE in purple. Each design corresponds to a stage in the cast member's activity story, from an incomplete start through connection with others to a moment of change. The project describes the items as retained fragments that record the cast's existence, not standard character goods. PANDORA stated the initiative aims to create revenue opportunities that do not rely solely on live streaming. The keychains cost 1,600 yen each and will be sold through a BOOTH page.
