Despite his imposing figure, he is very eloquent and soft-spoken. He is also known as the 'good cop' to Sada Mizuki, often mothering him. Yet, he can resort to false-starting for charge knockdowns just to gain psychological edge, prompting many of his juniors to think he was a reformed delinquent because he fought off many delinquents by himself using boxing techniques, and shouldered all blame to quit sumo club so others can train in peace.
He sometimes employ head games by deliberately false-starting to unsettle Ozeki. As well as his sumo skills, he also has decent boxing skills, as shown when he fought of delinquents without throwing anyone.
