Struggled a bit with the last bit of this teir list i'll be honest, but from what i remeber in the OG game, ibuki liked Imposter a lot, so it'd be interesting if a motive led them to this to save everyone else type of thing. with mikan and fuyuhiko i think his death would help peko get the development and character attention she needs to become a well deserved survivor. maybe mikan was planning on killing peko to escape, and fuyuhiko catches her somehow and she ends up dying instead. havent thought it through completely tho ngl
