There are two types of revenge anime enjoyers

Redo of a Healer was more or less less of a Revenge anime and more of a unfortunate guy who was tortured for years by horrible people went back in time now with bad mental state gets tortured again learned of his past memories and then continuously decided to do it with past violators for some reason

It's still a revenge anime tho, he carried out revenge against those who oppressed him earlier

No you right, I honestly don't even know what I was trying to explain

That is a mid ass anime, go play black souls, is what redo of healer tried to be, expect this game is actually good
