They're all canonically 18 according to the creator.I see everyone talking about this lately and uuhhhh it seems to feature heavily sexualized underage girls?
It's weird to see something like this being so popular in era, am I missing something?
But also… it is a dating sim-type of game. I also don't really know how much it goes out of its way to sexualize them, all the "normal" content in the game with them is pretty wholesome.
