Huh, why was the Genderswap tag removed? It seems pretty core to the premise that this is about a deceased male yakuza gangster in a new mother's body. If a later twist reveals something like "oh it was never a genderswap, it's mania brought on by post-partum depression" or something, that wouldn't change the theme or presentation of the story. (and IMO it'd be in poor form to have the presence or absence of a tag that seems like it should be there spoil the setup)
