Izuru appears as a cold and emotionless person who finds everything and everyone boring. 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. Notably, he appears aware that he is only being used and his talents are "leeched off" to create hope he finds boring and predictable, but he has no motivation to change his situation.
