Manga
A bespectacled, long raven-haired beauty who was once Toutaku's second-in-command. Intelligent, seductive, and manipulative, her power lay in manipulating others into doing her dirty work as she is otherwise an average fighter. She helped set up the events that led to Ryubi's dragon being awakened three years before the start of the series. She offered to help Enjutsu get the respect he should have had as Nanyo's leader at the time. Knowing Teifu's feelings for Ryomou, Kaku disguised herself as Ryomou and faked a video in which she was about to be raped by Enjutsu's henchmen. Teifu fell for it and was forced into attacking Seito and look for Ryubi in order to protect Ryomou. In reality, the entire plan was devised by Toutaku in order to see how powerful Ryubi's dragon was. After Toutaku's death, Kaku switched sides and joined Sousou, who accepted her with open arms. She became (or always has been) Kakuka's lover, plotting to take advantage of Sousou's power. She was genuinely in love with him until he was taken out of action. However, she gets into a sexual relationship with whomever she plots with (Toutaku, Kakuka and now currently Junyu). She knows of Koukin's crush on Hakufu (although it 's possible that everyone in the series knows it). She also teased Koukin by taking off her underwear in front of him before three other Kyosho girls seduced him in an attempt to make him defect from Nanyo. She suspected Shuuyu's plan of bodily harm, but failed to plan accordingly.

Anime
She acts more submissive in the anime than in the manga but is also more trusting and trustworthy. She is less seductive and does not act as calculating or as cunning. In fact, she seems almost caring towards Sousou and his friends, leading them to trust her more or at least be less suspicious of her. She also gives out the orders to Myosai to search for the Dragon Jade. She could have been working for her own needs after she was told by Sousou that she was no longer necessary for his plans. However, she was not involved in the Battle of Chibi. The next time we see her after she was removed from her position is when she meets up with Kakouton at the end of the series.
