Transient from Wa no Kuni who is a part of Shibuya Ward's Yoyogi Academy's sumo club. He has a self-restrained personality that respects the rules and directions of organizations and the pecking order. Those in the same club like this nature of his, but they also have thought of it as too inflexible and straight-laced. Of note, he's been relentlessly struck and pushed back many times by hearty and rough opponents. On the other hand, he's weak to openhearted good will and temptation, and he possesses an innocent side that would immediately swear to marriage. He has a habit of moving forward with actions that are like gouging at his old wounds. Yasuyori suffers from memories of his past, and he worries about not having a place to live outside of the battlefield. He has a deep respect for the doctor at his school who is always looking after his mental health.
