Butterfly Mansion

A Kimetsu no Yaiba parody that skips the demon-slaying and gets straight to the mansion's off-duty hours, where the corps' women are a lot more available than the source material ever let on.

The setup is thin by design: you're a guest at Butterfly Mansion, and your job is to spend time with the slayers and assistants living there until things turn intimate. There's no war to fight, just a house full of women with growing routes to work through.

Play revolves around a small sandbox loop, moving between rooms, checking in on residents, and building up individual scenes with each woman over repeated visits. A dorm stats screen tracks where you stand with everyone, and a solo training option gives you something to do between encounters. New residents and their scene chains have been added over time, so the cast isn't static, but the core activity stays the same: pick a girl, spend time with her, watch her arc play out.
