He is characterized by navy blue hair and purple eyes. An 18-year-old (high school sophomore) male. His height is 175cm. He has a calm personality, but when he gets angry, he emits a murderous aura (?) that is terrifying. He spent his childhood with Ibara at a private military facility. Since Yuzuru was an instructor and Ibara was a trainee, he trained Ibara very harshly (?). He does things that provoke Ibara, such as teasing him by mimicking his way of speaking (but he dodges everything.. lol). He is a member of the circle 'Niki's Kitchen,' so he encounters Ibara frequently. He is an idol and a member of the group Fine. Since the leaders of Fine and Eden are close (?), they meet often. However, whenever they meet, the atmosphere between Ibara and Yuzuru is heavy. He generally uses polite speech, such as adding '-sama' to names, but Ibara is the exception. He is simply called Ibara.
