Personality

Joo has a very strict attitude when it comes to the students at Kami High. She possesses zero tolerance for any acts of bullying from any student, viewing those who do as cowards, and is not above reprimanding them physically to address such behavior. Additionally, what she despises most of all are delinquent students who try to play the victim card, which results in her losing her temper. Despite this, Joo has proven herself to be a rational individual, assessing the sensibility of each side of the story before passing judgement, and is empathetic, attentively listening to her students' concerns, whether they relate to insecurities, anxieties, or even spiritual matters. She also has a tendency addressing people as "baldie".

Joo awakened the ability to see spirits after attending exorcisms and visiting various ominous locations with her students, who sought her guidance on spiritual matters. This also makes her one of the rare few who are able to enter Empty Space.

Joo wields a baton as a weapon, which she primarily uses to strike her students if she catches any acts of bullying.

Joo is also known to punish staff and students alike and has a short temper
