Redo of Healer

When Keyaru gained the powers of a Hero, specializing in healing even the gravest wounds, it seemed he was destined for greatness. Instead, he endured years of relentless torture and suffering. Unbeknownst to his tormentors, his healing abilities let him secretly absorb the memories and skills of those he treated, slowly making him the most powerful of all. But by the time he reached his full strength, it was already too late-he had lost everything. Now, resolved to reclaim his life, Keyaru casts a spell that rewinds the world to the time before his suffering began. Armed with the pain of his past, he sets out to do it all over again-this time with a single goal: revenge against those who destroyed him.
