Izuru is the end product of The Izuru Kamukura Project. Due to the drastic changes that the operations made to turn Hajime into Izuru, his original personality was suppressed 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 himself politely. He expresses disgust for talentless people because his "teachers" taught him that they are just parasites who oppose and leech off of those with talent instead of acknowledging their "true superiors". He believes that such people brought the world to a deadlock and created a world that has stopped evolving, and that the only way to improve this is a certain form of "selection". Because of his constant boredom, Izuru is highly resilient to unpleasant events happening around him. Izuru enjoys unpredictability, which can make him feel more emotional, but he also tends to quickly grow bored because his supernatural analytical skills and intuition cause him to quickly predict things with surprising accuracy.
