Redo of Healer (Season 1)

Redo of Healer (2021) is a dark fantasy revenge anime you can watch online on iFILM. In its world, healers are treated as disposable tools, and Keyaru spends years mending other people's wounds while being abused by the very party he serves. Then he discovers that the healing class is secretly the strongest of all.

By then it is far too late, and he has already lost everything. So Keyaru rewinds time four years, back to a point before his ruin, and starts over with full memory of everyone who broke him. This time he knows exactly how to settle each score. It is an isekai turned inside out: instead of a bright-eyed hero, you get a protagonist with a single cold purpose, pursuing it methodically and without mercy.

The series is adapted from Rui Tsukiyo's light novels. A fair warning: it is brutal, leaning into graphic violence and adult content, and it is not for everyone. But if you want the genre's darkest corner with none of the edges sanded down, this is it. One season. Stream Redo of Healer online on iFILM.
