He is malicious and very jealous of a fellow student of the Hamakaze school named Toramaru, having bullied him on purpose and dampened his self-esteem, after witnessing his rapid progress. Later on, he beats Toramaru up on the street for not paying a bill to a nearby restaurant and the latter becomes suicidal, but is taken under Kaoru's wing.
After finding out that Toramary is training in Sumo under Kamiya Kaoru's guidance, Senryoyama attempts to stop him at all costs, but with his new strength, the former is able to beat him up. Upon Himura Kenshin's advice, he agrees help Toramaru train in order to redeem himself for being contemptuous towards him.
