well there isn't any harem and it's actually quite good also if people are gonna backstab MC then what's the point of MC trying to save Earth he should just bring over his family and his people over to the other world if the Earth people wanna side with obviously bad side and know if they side with them they are technically gonna lead to earth being destroyed. Also for the backstabber MC shouldn't kill them he should fucking torture them for the backstabbing him honestly I feel like death is too good for them
