>>4646217Jutaijima manages to focus the heroines and protagonist into an isolated setting. It makes it so the environment they have to develop with is one that they can only do with each other, basically, the heroines only have themselves and the protagonist to actually talk and interact to, it makes getting to know them a bit more unique; because when you're stranded on a deserted island with a deadly virus that can only be cured by gratuitous breeding, the only options to do are to talk to each other and develop as characters, or breed like minks.
Meikoku sacrifices this isolation for a more populated setting, which is on the flipside of Jutaijima. I guess in a way, it sort of muddies the focus off the main heroines a bit for "literally who?" heroines. This isn't a bad thing in its own merit though, because it is nice to know that the setting -- a school -- isn't a fucking ghost town, and that Butcha actually spent time making sprites for the literal who girls instead of making them ghosts in an empty school besides the heroines.
