Re:ZERO
Its a scaling mess and the MC gets fucked up by the whole verse. Some primordial witches just created the world as playground for those that inherit their wills and everything breaks into chaos, so the only way to defeat anyone or anything is by dying, returning back in time and adapt and learn....bring up new strategies....making death and knowledge the only thing capable to go against witches with primordial god status and their overpowered followerships.
It is such a beautiful mess, I doubt any of ya little shonen boys can exist there for long with their og powers.
