Yōko Katori

"My grades are pretty good even if I don't study. [...] That's because I'm a genius."

- Yōko Katori about her abilities.

Yōko Katori (香取 葉子) is an All-Rounder and the captain of Katori Unit.

Appearance
Katori is a girl with medium-length magenta hair with bangs, and green eyes.

Personality
Liberally calling herself a genius, Katori can easily come across as arrogant, lazy, and extremely self-satisfied with her talent, which allows her to achieve stellar results at anything she tries her hand at with very little effort. However, her enlistment in Border has caused in her a crisis of confidence, which first manifested in her repeatedly changing her class. Though she claimed to have grown bored with each class she switched out of, in reality she perceived an insurmountable wall separating Border's strongest agents from her, which discouraged her from devoting time and energy to honing her skills: if before she never felt the need to work hard to improve herself, her experiences competing against Border's top agents taught her that there was no reason to do so in the first place, as matching them would be impossible, despite having never made an effort. She began to believe that where her talent takes her is the farthest extent that can be reached and any additional effort is meaningless.

After dropping to the mid-tier of B-rank and losing to Nasu Unit her frustration caused her to appear apathetic about her unit's ranking, whereas the defeats deeply demoralized her and filled her with self-loathing, which further fueled her self-defeatist attitude. She developed a tendency to lash out harshly when criticized, playing her superiority against the interlocutor to disqualify their opinion. She took the defeat at Tamakoma Second's hands especially hard, so much so that she considered quitting Border altogether, which Yūta Miura understood to be because she actually envied their opponents' ability to work hard towards their goals. It is only then that she discloses her displeasure with being unable to apply herself.

Hana Somei
Somei is Katori's childhood friend and next door neighbor. She would often come to Katori's house only to find her playing games. When Somei was prohibited from visiting Katori, Katori switched her bedroom with her brother, since his bedroom faced Somei's bedroom, and opened a window in the wall so they could talk, although she said she only wanted to organize her room. After learning that Somei saved her instead of her own parents, and learning from Somei that she planned to join Border, Katori decided to join with her. Somei is usually the peacemaker to Katori and Wakamura's fights, coldly scolding them at such moments.

Rokurō Wakamura
Katori and Wakamura are often at odds due to their different views.
