Originally Kunieda Aoi's second-in-command, Nene is far more aggressive than her permissive leader. Though she often openly disagrees with and occasionally disobeys Kunieda, she is still her faithful wingman, balking vociferously when Kunieda opts to leave the Red Tails and relinquish the mantle of leadership to her. She takes it nevertheless and soon proves to be worthy of it, gaining the confidence and trust of the Red Tails as their fourth leader. Her weapon of preference are chains, which she uses proficiently to gain an advantage against stronger men. As Kunieda, she is a second-year student.

Йегрина е принцесата на кучетата в животинския свят и е изпратена да накаже човечеството за всичките престъпни деяния, които са извършили, като ги превърне в животни.

The protagonist of the series, busty, light red haired and green-eyed and not terribly bright, but immeasurably powerful. Hakufu cares little for the politics of the series, only caring about fighting for the sake of fighting, but is staunchly against unnecessary violence and killing. Lately, however, with trouble brewing all around her she is beginning to take up the mantle of a leader to protect her friends and family. Hakufu possesses a unique gift for predicting enemy moves very accurately by reading the flow of chi (which proved useless against Ukitsu) around her opponents which occasionally makes her seem brighter than she is. She also inherited Master Chouchou's knowledge of chi magic, and, while currently unaware of this, is able to use it partially by instinct. Choushou passed it to her spiritually while Hakufu was unconscious, this is how she healed Koukin after she stabbed him and extracted the evil chi from his body. Hakufu harbors a powerful dragon as one of the Three Great Rulers.

A beautiful woman with prodigious fighting skill. She acts as Munsu's 'Sando', or bodyguard. When she was kidnapped by a corrupt lord who wanted to make her his personal bodyguard, her lover embarked on a futile quest to become an angyo onshi. He died in the process, but not before making Munsu aware of her plight. After Munsu frees her, she decides to become his bodyguard in memory of her dead lover, and takes the title "Sando" as her new name.

Despite her fearsome natural fighting ability, Sando is quiet and shy, with a high moral stance. As a result, she is often in conflict with the amoral Munsu over his questionable methods. She has made it clear that if he ever becomes truly evil, she will no longer protect him. She also has a great fear of heights, and will refuse to cross bridges set over deep mountain gorges or valleys. Munsu finds this extremely peculiar, seeing as to how she often leaps several stories into the air during combat.
