Touhou: Heartbound [Demo] [CartoonSensei]

November 15, 2026F95

An adults-only, unofficial Touhou fan dating sim. Live at the Hakurei Shrine alongside Reimu: follow her daily routine as days pass and the weather changes, explore and build in a block-based open world, help keep the shrine tidy, and grow your relationship through tea, prayer, feeding the koi and other activities you can do together. As you get closer, she starts taking the initiative herself.
