Redo of Healer

A disturbing yet controversial anime This "anime" (i can believe it’s not hentai) depicts of the main character who been summoned in a fantasy gifted with the ability to "heal" people and helps his "group" destroy demons and all of those supernatural agencies. He was generically useless as a result he recieved severe and traumatic punishment from a princess named “Fraya" he was drugged, beaten, spoilt, even r**** by other characters he has no relations with. And so he was tired of all the torture so he fights a demon and defeats and takes out some sort magical material (notably daimond) out of her chest and uses his "healing" power to reverse time exactly 4 years before he joined the group to start his revenge. coming to realisation that his own "healing power" can practically do anything than just heal people given him this overwhelming strength. Including the eye of truth were he can reveal statistics of an adventurer and poison resistance (when he eats poisons mushrooms/drug but isnt affected in any way). He then decides to find Fraya (since she tortured him the most) he then beats her up then pulls out 5 of her fingers and then uses "heal" to revert it back to normal then begins to ravaging her. I would 99.85% not recommend watching/reading this (the manga is far worse) even though i know people may have watched it and came to this definition to see my POV. If you wanna see true dark fantasy just watch Berserk or something idk
