Having faced hardship since childhood, Tomo is sadistic and cruel. His mind is contorted and he is severe with others. It is said he was taken in by dancers when he was young, exposing him to the world of Chinese opera. This fact would explain why he wears a Chinese Opera costume. Tomo is one of Nakago's most trusted allies because he freely discusses his plans with him. (Source: Wikipedia)
The childlike goddesses serve Taiitsukun and reside at Mount Taikyoku with her. They are also known as Lai Lai. They can take the appearance of floating orbs and can appear when commanded. They have healed Miaka and her warriors when it was necessary, also offering to fix Nuriko's perversion (much to his dismay) and Taiitsukun's face (much to her annoyance). Their other function is to serve as vessels for the spirits of the dead Celestial Warriors, so that they can fight along side their priestess, in which case they take on the appearance of whomever they are inhabited by, and have all of their powers.
In the first part, Benawi is the Samurai Leader of Kenashikourupe. When Hakuoro's rebellion overtakes Kenashikourupe, Benawi realizes defeat and kills the emperor, to spare him from possible torture and humiliation, then attempts suicide, but Hakuoro stops him, convincing to join him as his right-hand man. Benawi has a strong sense of responsibility to his country. He carries a calm and logical personality, but gets irritated when Hakuoro ignores the duties as a ruler. The main weapon of choice is a halberd, which he uses most effectively whilst riding. A man of convictions and morals, he believes that the people in a country should come first, and is not afraid to tell even an emperor when he believes they are making bad decisions. A cunning tactician, second only to Hakuro, Benawi is able to remain calm under pressure, and is able to adapt to unexpected changes during a battle. Of all the characters, Benawi seems the closest to normal human appearance, as his ears are never seen in the anime.

Dorii and Guraa are twin archers serving under Oboro. They are talented archers and often lead archer groups in Hakuoro's army. There are few ways to tell them apart. For one, Dorii has purple eyes while Guraa's are blue. Also, the bottom part of Dorii's clothes are blue while with Guraa they are red. You really can't make them separate characters since they're always side by side. They are somewhat androgynous, and as such their gender is difficult to ascertain, even by other characters. In the game, they reveal they are male, in the anime their gender isn't revealed.
Ditzy principal of the school. She is the one that allowed Takeru, Haruno, Inaho, and Himegami to all live under the same roof. She brandishes incredible power and control over element as she was able to break through amazingly powerful barriers, with her bare hands, thanks to nothing more than, in her own words, her "fighting spirit". She was in the maken-ki of the school before it became an all girl's school.
