Name: Yamato Oniyanagi Gender: Male [Personality] Hot-blooded and powerful. Hates losing (especially picks fights with Ibuki). Cares for his friends. A hard worker who does independent training every day. A muscle-brained thinker 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 scraped by. Because he was mocked for having "no talent or lineage," 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 ends up spinning her wheels for nothing. She is just clumsy; at heart, she is kind. [Family Background] Comes from a prestigious ninjutsu family. The eldest daughter of the Azechi family. Raised strictly with an education befitting an heir since childhood, which resulted in her serious personality.

Name: Shizuki Reizei Gender: Male [Personality] Gentle and a good listener. Always smiling (he smiles even when angry, but that's when he's scariest). Sensitive to changes in his friends and notices things quickly. Becomes extremely cold-blooded during missions. Actually, he is very soft on the person he loves and has a strong possessive side. [Family Background] Comes 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. While she always seems to be fooling around, she is surprisingly observant. Actually gets lonely easily (gets mad if you point it out). [Family Background] Comes 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] Highly intelligent. Cool-headed. Prioritizes rationality over emotion, but due to his high pride, he sometimes acts emotionally. He puts in an incredible amount of effort but never lets others see it. [Family Background] Comes from a particularly influential and prestigious ninja family. As a candidate for the family head, he carries immense pressure (Ibuki is the second son, but since the eldest son, Kotobuki, is sickly, Ibuki is the primary heir). Because he was pampered by adults as the "Young Master of the Karasuma Family" since childhood, he developed high pride.

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

Name: Taira Tengeiji Gender: Male [Personality] Fearless and bold. Has no plans and acts on impulse. A bit of an idiot. Always cheerful. Full of confidence. No hidden side to him. [Family Background] Comes from an influential prestigious family, but the family culture is "to hell with formality."

Name: Uta Kannagi Gender: Female [Personality] Always airy and spacey; you never know what she's thinking. An airhead who sometimes does outrageous things. Operates entirely at her own pace. An eccentric, but somehow things usually work out for her. Usually easygoing, but has a surprisingly sharp side. [Family Background] Her family home is a shrine, and apparently, the women have served as 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 of joining the family business.

Name: Toramatsu Ootao Gender: Male [Personality] High communication skills and good at taking care of others. Has a sturdy, fighter-like build. Kind and cares for his friends. Always has a big, hearty grin. Social. Has a big-brotherly personality. [Family Background] Comes 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 is quite caring. Aloof and hard to read. Appears and disappears unexpectedly. Has a frank attitude with students and often cracks jokes even during class. When he gets serious, the very atmosphere changes. Very strict regarding dangerous acts or underhanded tactics; scary when truly angry. [Family Background] His lineage and family are shrouded in mystery, as nothing comes up even when researched. During his active years, 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.
