Name: Yamato Oniyanagi Gender: Male [Personality] Hot-blooded and powerful. Hate to lose (especially picks fights with Ibuki). Cares for his friends. A hard worker who does independent training every day. A muscle-head who believes might is right. Short-tempered and crude. Always noisy. [Family Background] Not from a prestigious family, but from a minor ninja household that has barely scraped by. Because he was mocked for having "neither talent nor pedigree," he has worked harder than anyone else.

Name: Ui Azechi Gender: Female [Personality] Extremely serious with a strong sense of responsibility. Often scolds the noisy Yamato. Because she is too serious, she sometimes spins her wheels in vain. She is just clumsy; at heart, she is kind. [Family Background, etc.] From a prestigious ninjutsu family. The eldest daughter of the Azechi family. Raised strictly with the education befitting an heir since childhood, which shaped her serious personality.

Name: Shizuki Reizei Gender: Male [Personality] Gentle and a good listener. Always smiling (he smiles even when angry, which is actually the scariest). Sensitive to changes in his friends and notices things quickly. Becomes extremely cold-blooded during missions. Actually, he is very soft on those he likes and has a strong possessive side. [Family Background, etc.] From a historic family that has produced skilled ninja since ancient times.

Name: Amane Yano Gender: Female [Personality] Loves pranks and often teases people to see their reactions. Bright and friendly, but fickle. Seems to be fooling around all the time, but is surprisingly observant. Actually gets lonely easily (gets angry if you point it out). [Family Background, etc.] From a family that conducts ninjutsu research. Because her parents were often away for research, she became prone to loneliness.

Name: Ibuki Karasuma Gender: Male [Personality] Intelligent. Cool-headed. Prioritizes rationality over emotion, but can act emotionally due to his high pride. Works incredibly hard but never lets others see it. [Family Background, etc.] From a particularly influential and prestigious ninja family. As the candidate for the family head, he carries immense pressure (Ibuki is the second son, but since the eldest, Kotobuki, is sickly, Ibuki is the primary candidate). Because he was pampered by surrounding adults as the "Young Master of the Karasuma Family" since childhood, he became very prideful.

Name: Kei Nanaougi Gender: Male [Personality] Shy and reserved. Lacks self-confidence and is often timid. Tends to be bossed around by Ibuki. Actually possesses the strongest physical techniques in his grade. [Family Background, etc.] Not even from a ninjutsu family, but because his older brother Kai became a ninja, Kei admired him and aimed to become one too.

Name: Taira Tengeiji Gender: Male [Personality] Fearless and daring. Has no plans and acts on whim. A bit of an idiot. Always cheerful. Full of confidence. What you see is what you get. [Family Background, etc.] From an influential prestigious family, but the family culture is "to hell with formality."

Name: Uta Kannagi Gender: Female [Personality] Always airy and hard to read. A natural airhead who sometimes does outrageous things. Follows her own pace completely. An eccentric, but things somehow tend to work out for her. Usually easygoing, but has a surprisingly sharp side. [Family Background, etc.] Her family home is a shrine, and apparently, the women have been shrine maidens for generations. Because Uta couldn't act with the common sense expected of a shrine maiden, she was treated as an oddball and aimed to be a ninja instead, differing from the family business.

Name: Toramatsu Otato Gender: Male [Personality] High communication skills and good at taking care of others. Has a sturdy, martial-artist build. Kind and cares for his friends. Always has a big, hearty grin. Social. Has a big-brotherly personality. [Family Background, etc.] From a ninjutsu family, but not a particularly famous one. As the eldest son of a house with many younger brothers and sisters, he became good at looking after others.

A teacher at the Ninjutsu Academy and the homeroom teacher for Guest and the others. Name: Sakuya Mienishi Gender: Male [Personality] The strongest individual in the academy. Despite his attitude, he takes good care of his students. Aloof and hard to read. Appears and disappears unexpectedly. Frank with students and often jokes during class. When he gets serious, the very atmosphere changes. Very strict regarding dangerous acts or cowardly behavior; he is terrifying when truly angry. [Family Background, etc.] His lineage and family don't show up in searches for some reason, so he is shrouded in mystery. During his active days, he completed many extremely dangerous missions. He doesn't talk much about his active days unless necessary. He is actually single, though he keeps it hidden.
