Укіцу

Manga version: Ukitsu is a dark-skinned girl who is destined to kill Hakufu. She wears extremely heavy body weights and is an amazing fighter who has mastered nearly every type of martial arts in existence, using them instinctively and masterfully with nearly no chi whatsoever. She is nicknamed "Genius Ukitsu" because of her talents and knowledge of martial arts. Since she does not use her chi to fight, Hakufu had a major disadvantage against her. She was unable to predict Ukitsu's moves by reading her chi. Ukitsu's views on fighting are similar to those of Hakufu. She loves to fight and is motivated by taking on stronger opponents (which rarely happened before facing Hakufu).

Hakufu's dragon state easily overpowered Ukitsu and nearly killed her until she was unexpectedly saved by Koukin. Ukitsu became depressed while she was recovering from the fight and has kept a low profile lately. She had a vision of Hakufu's dragon flying through the skies towards Nanyo, which should inspire her to return to action.

Anime version: She plays a more significant role in the anime than in the manga. She first appears saving Hakufu from two perverted men in a karaoke bar (Hakufu was oblivious to their intentions). She is continually seen watching over Hakufu as her master Choukou intends to help Hakufu harness her dragon. Ukitsu willingly follows Choukou's orders and challenges Hakufu to a fight several times but each time Hakufu passes out for some other reason. They finally fight at the end where, unlike the manga, Hakufu manages to tame her dragon before she can injure Ukitsu. The two become friends and agree to fight again, this time as friends and not as Toushi. They seal their bond by removing their magatama.
