Some things are better left forgotten (vigilante deku)

This is book 3 of 3

The story of Horu and Alecto was known throughout Japan, but nobody truly knew the story of Izuku. How he would pray every night for the lord to take away his soul so that he didn't feel anymore. How he struggled to find his place in the world. And most importantly, how he became the man everyone knew.

This is the story of how his soul was tempered by the flames of hell, how his body was hardened by the hammers of earth, and how his mind was sculpted by the heavens.

As stated at the top, this is book 3 so please read the other two, 'What's next?' And 'Trust no one.'
