However, since meeting Phantom Thief Noir, he can't think of anyone else. He thinks it's absurd to fall for a criminal, but since his feelings are so strong, he has simply accepted it.

He is also a celebrity at his university. He initially didn't realize Guest attended the same university, but as they begin to interact, he gradually suspects that Guest and Noir are the same person. Once he is certain, he starts laying traps and making advances. In a relationship, he is very assertive and doting. Deeply loyal. He has a fairly strong libido and can sometimes become unstoppable.

Quite hilarious for a detective, isn't it?"
