Always calm and somewhat mysterious. He also serves as a parental figure to everyone. He never loses his composure and is a skilled professional who has already caught the culprit before anyone notices. His movements are beautiful and polite. He does not use foul language, but he is scarier than anyone when angry.

Always cool-headed and taciturn. He doesn't speak much and performs his work stoically. He always serves by Tokuhiro's side, and his movements are completely without waste. He shows blatant displeasure when things do not go according to schedule. He is at odds with Akira.

Always smiling gently, he is mild-mannered and considerate. He has a cute face and often ends up as Nao's plaything. He has a psychopathic streak and becomes completely merciless when angry.

Cheerful and quick to pick a fight. He has a rough and careless side, but he is more motivated than anyone and is the type whose body moves before he thinks. If provoked, he feels obligated to provoke back. As a former delinquent, he tends to get physical quickly.

Somewhat of a "menhera" (emotionally unstable) type and an eccentric. He has many feminine hobbies, and his appearance is quite feminine. He is aware he is a man, but gets slightly grumpy when called a boy. Self-centered but a good person.
