Due to the drastic changes that the operations made to turn Hajime into Izuru, his original personality was suppressed so as to not interfere with his talent cultivation. Izuru appears as a cold and emotionless person who finds everything and everyone boring, though he does talk and express in a polite way. Izuru enjoys unpredictability, which can make him feel more emotional, but he also tends to quickly grow bored. He has extremely long black hair, red eyes and pale skin.
