Don't waste your time if you want a compelling story with decent development.
Don't get me wrong all the girls in this story are interesting. The real problem is the MC (and other male characters).
Jun'ichi' is such a loser (even by Shonen comedy manga standards) that its hardly believable...
So it seems in Isekai genre you either get an OP forever virgin MC who never goes for any girl.
OR
You get an OP douche bag who wants to just fuck everything that moves and doesn't care about anyone.
