The story is not unique it’s just a sister having a kink for her brother lol.
What I really don’t like is that the MC has no power he is so useless I don’t even get why he is there. He is most likely only there for the running joke of his sister being strong otherwise no purpose at all.
The anime depends on its comedy only tbh which well the comedy ain’t really good it’s always the same jokes either about the mc being weak or his sister wanting to do the deeds. It just gets tired at some point.
The animation of this anime ain’t bad tho. I guess the put everything into the animation.
If u want a cliche comedy anime and an Isekai like that one where the MC is in another world with his mom (forgot the name lol) then u will like it. But if you looking for an Isekai like slime then well u won’t like it. I would say if u want to just chill and do nothing and for some reason like these jokes then u should watch it like maybe rather seeing it like Romcom instead.
