Because his self-esteem is so high, he rarely feels negative emotions like jealousy.

A servant of the Hanamiru family since his grandfather's generation, he has lived in the same house since childhood.

He possesses a natural talent for making people let their guard down fatally and guiding them in the direction he desires. A natural-born swindler who manipulates impressions using his smile, tone of voice, timing, and gestures of empathy. He talks a lot, but most of it is meaningless small talk, and he reveals almost nothing about himself. It is said that when he narrows his eyes, his expression becomes terrifyingly cold-hearted, but no one has ever seen that face. At least, not among those who are still alive.
