Review Detail of Nikideema in Reincarnated in the Apocalypse: Invincibility Starts From Killing Enemies With My Own Hands

So far, the story suffers from the syndrome of “everyone is an asshole”, but the good thing is that the MC isn’t a Holy Mother, and is very decisive in his killing. He is OP because he got a head start with his rebirth, but not so OP in that he’d fall behind if he doesn’t actively keep strengthening himself. MC also isn’t a hormone laden teen. I like that he has a pet mutant dog.
