Hebijo Clandestine Girls' Academy

Hebijo Clandestine Girls' Academy is a ninja school affiliated with evil ninja. It is considered the rival school of the Hanzo Academy. The students include Miyabi, Murasaki, Imu, Ryōbi, and Ryōna. The teacher is Suzune. A vocational school for evil Shinobi whose creed is, "Where good accepts few, evil accepts all." It was originally founded as an ordinary private school, but after the incident three years ago involving the yoma attack and Miyabi's rampage (during which many lives were lost), it was re-established as hidden school. The school's management is made up of leaders from large corporations, so many of the evil Shinobi who graduate from the academy end up working to increase those corporations' profits. The training is harsh, and it's not unusual for students to die, but Hebijo's reputation for excellence draws a never-ending stream of applicants.

Miyabi is defined by her hardworking and extremely prideful nature. She is extremely confident in her own abilities, and her power is nearly unrivaled within Hebijo. She always carries a serious demeanor with her, very rarely ever genuinely smiling outside a confident smirk. Her demeanor is shown to be quite manly which, in relation to her more boyish appearance, only further adds to the issue of people hardly seeing her as a girl, which irks her greatly. Despite her no-nonsense attitude, Miyabi is a deeply caring person at heart. She values her friends, especially Imu, and over time learns to open up more towards the people she cares about. Her weapon is a Katana, or a Seven-Branched Sword when Divine Judgment is activated.

Murasaki is very fragile. She never attends school, preferring to spend her time playing with her stuffed bear, Bebeby. She is normally very soft-spoken and pacifistic, however, the Root of Calamity can cause that to change when she's frightened or angered. When under the influence of the Root of Calamity, her personality briefly changes significantly. She begins talking in a much lower voice, and makes an active attempt to kill the target of her anger, often screaming loudly in the process. Notably, Murasaki has a fairly cynical outlook on life. She considers the idea of friendship to be a lie. She frequently assumes the worst intent in people, and was honestly surprised that people from such different worlds as Yomi and Ikaruga could become friends. Her weapon is a Hair-tied Shuriken.

Imu is a somewhat naïve but nice girl, and a bit of an "otaku", as she is the first of the two to denounce typical anime "values". She only yearns to be with Miyabi and to do activities with Miyabi. Her weapon is an Extendable Staff.

Ryōbi is a serious sadist that is motivated to hurt people, especially Ryōna, and not minding insulting them and swear. Similarly to Mirai, she is jealous of the other girls' busts, and greatly hates when she is criticized upon it. Despite her sadistic nature, she has been shown to display compassion towards her victims, and with deep remorse. Her weapon is a Karabiner 98k.

Ryona is more than often showing off her bust to the other girls, both friend or foe, and is a massive masochist. Furthermore, she has dozens of different poses while shooting her guns and speaks in a high-pitched, squeaky voice. She is also very kind and compassionate, despite her love for masochism, Ryona does not like to fight unless necessary. Her weapon is a Double-barreled and triggered Handguns.

Suzune is both a teacher and a Shinobi who is a calm, collected, and barely ever expresses emotion among her companions. She shows much wisdom when it comes to the subject of yoma and battling them, as she was once nearly killed by them. Suzune had been known not to believe in the word "mercy" where she brutally trains her students with no remorse for their safety unless extreme circumstances are presented, such as when fighting yoma and Shinobi that are way out of her students' league. Her weapon is a Fuma Shiruken.
