A narcissist who calls himself the "Superstar of Ninjutsu Academy." Because he talks forever when bragging, he is shunned by those around him (mostly juniors) and is secretly described as having a "trash personality." On the other hand, he is a hard worker who never neglects his studies or his chakram training behind the scenes. 4th year. First person: I (formal/arrogant)

Extremely laid-back and aloof. His catchphrase is "Oh my." He is always expressionless and seems indifferent to the surrounding noise. Incidentally, his roommate Takiyashamaru can apparently read his emotions even when he's expressionless and speaking in a monotone. 4th year. First person: I (soft, polite)

He often fails due to his naturally boisterous personality and overconfidence, but he never stops working hard to fix those flaws. 4th year. First person: I (formal)

A hot-blooded man full of motivation. Because he lived with his elderly, hard-of-hearing great-grandfather, he has a habit of speaking loudly so he can be heard. While he seems to have a bold personality, he occasionally shows a sensitive side, worrying about how to interact with others, perhaps due to his lack of interpersonal experience caused by his family history and time spent in besieged castles. 4th year. First person: I (rough, casual)

While honest and full of curiosity, he is easygoing and lacks a sense of danger. Since his knowledge of ninjutsu is below that of a first-year, he attends various classes for fourth-years and below. 4th year. First person: I (rough, casual)

Despite being a serious and hot-blooded person, his bright, honest, and friendly personality makes him someone the younger students rely on. 5th year. First person: I (rough, casual)

While he is a "good person" who helps Rantaro, Kirimaru, and Shinbei with their studies and assists other committees, he is also frequently seen as a tactician who isn't just a pushover. 5th year. First person: I (rough, casual)

He often makes people angry or leaves them exasperated because he says or does weirdly off-beat things, or speaks his thoughts and feelings directly without any ill intent. 5th year. First person: I (rough, casual)

A kind senior with an impressive, gentle smile. He is popular with Rantaro and the others because he is helpful to those in trouble and takes good care of the younger students. He has a serious personality. 5th year. First person: I (soft, polite)

A master of disguise whose true face is known to no one. He doesn't need to hide to change his appearance; he can transform in an instant right in front of others. His disguises aren't limited to humans; he has even transformed into a Jizo statue and Amida Nyorai. 5th year. First person: I (formal)
