So far it's going to be another banger but it has a few problems with timeline in the first world(could say because it's a au that's why) and the second problem is Mc's age doesn't makes sense if he is around the same age as lily in pre time skip he should between 7 to 10.

LIKEUpdate read up 2 chapters into avatar So far it gets worse more things don't make sense. It purely OP MC does what ever he wants and no one care. Then the whole age part, makes things worse cause 3 year olds are talk in full sentence and the size of men. The characters are are more 2d than your anime waifu. Then there's the timeskips which makes it we don't bond with any of the characters including the MC. The romance is not existent, its a harem for the sake of being one. In all I wouldn't recommend reading this.
