Is like they put a shonen story in a seinen body, so i guess they are "cleaning" the story to have a larger net and get more eyes on it?
The MC is probably the worst part of all, having the usual salaryman getting in the body of a 0 to 16 year old in another world kind of dampens the personality dissonance, but here, the salaryman is the same old guy, but he has this bright, happy go lucky disposition and even when confronted with an actual danger (he somehow loosing the grip on the high level anomaly dragon), dude goes full power of friendship and hope, dismissing the threat, they could just have done away with that with some rule or something but now we are in this
