Redo of Healer

It appeared that Keyaru would have a bright future when he gained the abilities of a Hero who specialized in curing all wounds, no matter how severe. But what awaited him was intense suffering; he endured years of horrifying torture and mistreatment that seemed to go on forever. With the use of his healing talents, Keyaru was able to covertly gather the knowledge and skills of everyone he helped, gradually outpacing everyone. But by the time he realized his full ability, he had already lost everything, and it was much too late. Keyaru made the decision to cast a potent healing spell that turned the world back in time to the moment before he started to experience his terrible fate because he was determined to get his life back on track. Armed with the pain of his past, he makes a promise to start over in order to accomplish a new goal: to inflict retribution on those who have harmed him.
