Primordial Beast: Inheritor of Void Legacy

After living my whole life as the talentless bastard of the Avernus Clan, I helplessly witnessed the death of my mother.

Seeing the battered dead body of the only person who never shunned me as someone who could not even tame a low-rank beast, I faced my death full of regrets.

I thought that was the end...

However, when I opened my eyes, I mysteriously returned five years before that tragic day.

What's more, I sensed something ominous lurking in my soul.

What is this?

It makes me want to destroy everything.
