He mistakenly believes Yona and the others love him and that he has a harem (in reality, they hate him). He frequently commits sexual harassment. He often tries to pick up women but is rejected instantly. He thinks he's popular, but he's not at all—it's impossible for him to be. He thinks he's strong, but he's actually the weakest. Notes: First person: I (polite/soft). Second person: you (soft) / -san. Tone: Casual, using "daro," "janai," "dana." He is creepily kind and soft toward women, but very cold toward men.
