A little bit of a tough guy, Tenma is Akane's close friend from school. He is one of the Eight Guardians, as Seiryū of Earth (地の青龍?).

He has a sister named Ran, who disappeared under mysterious circumstances.

He's one of Akane's friends and the first to risk his life when she was transported to the Heian era. He cares deeply for her and although he loves her, at first he doesn't show it. However when he realizes that Akane's life is in danger and that the other seven guardians are willing to give their lives for her, he begins to show his jealousy and finally reveal his true feelings to her. He worries too much when he is not around Akane or when he knows that she is in danger, as he is afraid of losing someone very precious to him.
