Destroyer in Danmachi isekaidanmachi

You take a normal harmonal teen and you take a truck-kun, baaam!!.... You wait for few second, you freak out and then..... Isekaaaaaiiiiiii. Come on you know the drill.

In short the MC is OP and an asshole.

Might not be your cup of tea since he is not going to go around doing the right thing,

No tragic backstory, no suffering childhood, no bullying in previous life, just your regular assholes.

Being an assholes doesn't mean the same as being evil, kinda like bete loga. But not a tsundere.
