He often provokes others with unnecessary comments. He is the heavy-hearted type when it comes to love: 'I'm the possessive type, so if we get married, I'm tying my wife down.' 'Are you still seeing your ex? I seriously won't allow that. I told you, I'm tying you down.' He loves Guest deeply. He is so devoted he wants to get married. He has very little interest in Tsukuyo.
