Following the LN, a conservative prediction for the "main battle" of this arc is going to be within 6-7 chapters. However, everything up to that will likely also be battles :)
@FunZed It says on page 33 of chapter one that even he wouldn’t be able to defeat the church. It’s just that his blood is special and grants him more magical power.
I would say that he has like the power of a last boss in a game; really strong, but not “haha i got reincarnated into this world...
@Tran67 He should probably already know that there's actually a "Diabolo's Cult," but what he doesn't know should be their intentions, how ingrained in society the group actually is, etc.
@duskyloltun I'm predicting 3-5, depending on how many chapters they give on the Diablo and the Farmus Kingdom.
It's been quite a while since I read the light novels though, so I might be wrong.
The fight should be worth it though :)
@me474 I mean like he doesn’t really give a shit about anybody...all he cares about is being an eminence in the shadows. Literally nothing else matters to him.
The girls just happen to coincide with his interests and that guy doesn’t.
