Reign of the Wallenstein

Born as a child soldier in a war-torn country, Joey was destined for bloodshed. He spent half of his life on the battlefield, trying his hardest to stay alive.

Unfortunately, fate has another plan for him. Joey was involved in some unfortunate accident and died without glory to his name. And yet the death he was expecting didn't come for him.

Reincarnated as a boy with the same name as him, Joey Wallenstein must make sense of his new reality while trying to evade his airhead mother's attempt in suffocating him to death.

What happens when MHA meets Danmachi? Let's find out, shall we? Though I'm warning you, some characters might have their age altered by the whim of the author. So it might throw you out of the loop. Expect the unexpected!
