Keyaru is the main protagonist of Redo of Healer. On his 14th birthday, he was chosen as one of the Heroes, the Hero Healing.

After years of torture at the hands of his own allies, he manages to break free and get the Philosopher's Stone. He then uses the item to go back four years time to exact revenge against the people who tortured him.

Pre-Betrayal

Initially, Keyaru was a very kind and gentle boy with dreams. When he discovered that he was one of the Heroes who would save the world, he was very excited but he was afraid to use his power when he found out that by healing people, he absorbed their memories and pain.
