He went nuts on her because she harmed someone he cares about.
He also holds no grudges at all. So once she apologized and gave him her loyalty, his anger was done with.
He finally was recognized as the true hero. But what to so with god like powers in a fantasy world? Be with wifu or travel dimensions and explore? Both I'd pick.
I mean, if he can go back to his world, why not bring you, his wife with him? Just in case he might lose his power when he return, make sure to disguise or turn his wife into a normal-looking human if possible.
Duh, he can literally access to the magic system, nothing is impossible.
Nothing should stop him if he wants to return to his world and nothing should prevent him from bringing the waifu, the gang and the house along.
Now I wonder what more issues need to be dealt with in that world? Are we gonna deal with cosmic issues now seeing how godlike he becomes?
@Riger
I understand that, but the whole transition took just two chapters and maybe a couple of hours time-wise.
Forget not holding grudges, the MC is a Jesus.
