Ten-Ryuu
Riku Tachibana (太刀花 リク, Tachibana Riku?)
The main character of the show, Riku was originally borne in the Heian Era of Japan as Youmei. His mother sent him into the future, where he was taken up by Soutaru Tachibana, to avoid dying in the Chi-Ryuu raid on the Ten-Ryuu shirne. At the start of the series, he's shy, and easily scared. But when he receives the Ten-Ryuu Toujin drive containing Kogenta, Kogenta helps him to become a lot braver and stronger. He has no memory of his time in the Heian era until he goes to Naraku to reunite with Kogenta after losing him by Yuuma and Rangetsu. In Naraku, he sees his memory play in front of him, and learns of his past life. He is the head of the Ten-Ryuu.

Kogenta (白虎のコゲンタ, Byakko no Kogenta?)
The shikigami of Riku Tachibana. Kogenta is a member of the Byakko (White Tiger) family of shikigami (leading many to the conclusion that Riku is Ten-Ryuu's Head). He is typically cocky, arrogant, and quick to anger. At first he can't believe that he's "Stuck with someone as dimwitted" as Riku, but eventually comes to terms with this and tries to improve Riku's character. He is the first Shikigami to become a Daikoujin, but he considers it an unfair advantage because, in his words, "I can't remember how I beat them and by the time I come to, the fights already over." In the finale, Kogenta willingly lets Riku terminate their contract, but it is speculated that the contract still lingers, as Kogenta's spirit is seen over the shrine.

Teru Saigou (西郷 テル, Saigou Teru?)
The first real member of the Ten-Ryuu that Riku and Kogenta meet. Teru is broke, and nearly always in debt to someplace (A Hot Spring Hotel, a Beach Bar, and others). He is always happy to receive free food (on account of him being unable to buy his own), and always travels as "Training" as he calls it, normally leaving as soon as someone tells him the rent for wherever he is staying. He even develops a crush on Nazuna, who shows him the literal meaning of "crush". He consides Souma a rival (as both love Nazuna), and only enters the Fukumaden as leader of the Youkai Extermination Squad formed by Chi-Ryuu.
