Izuru appears as a cold and emotionless person who finds everything and everyone boring, and it takes a lot to interest him even for a brief second. He 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. He is neither on the side of hope or despair, and just wants to observe which one will triumph over the other.
