Hikage Tenma is a student from Kanazawa Kita High School and a member of its sumo club. He has won the title of Middle School Yokozuna in his third year. In high school he lead Kanazawa Kita High School to third place in tag team bouts during his first year. He won the the title of High School Yokozuna during individual bouts in his third year. He conquered the All-Japan Championship acquiring a Tsukedashi qualification. After graduating High School he joined Suzugatake Stable, to which his brother used to belong.
Unlike his brother, he is far more dedicated in his craft to become a yokozuna. Despite his individualistic ideals, he actually cries a lot about his seniors. Hence he was so aggrieved after he lost to Chihiro Kunisaki, when the high school club was knocked out 0-3 by Oodaichi High, despite him being the only one left in the individual competition.
He's also notorious for being highly asocial, disliking many of his fellow wrestlers. The only person he seems to be relatively close to aside from his brother is Onimaru, with whom he shares books and comics.
He is known for his strength and a quick and powerful strong toss, and a quick open palm strike, and he has all-round range in terms of attacking options.
Defensively, like most high-ranked fighters, he often lets opponents fight him in close range, as he is confident that he can't get lifted or tossed. Even when the brothers acts as the guardians of the Nagoya Temple, who normally hold back fighting at full strength. However, they will actually fight seriously in the later chapters in the historical story, and/or when provoked by onlookers in open challenges.
