Yōko Katori/Relationships

Hana Somei
Somei is Katori's childhood friend and next-door neighbor. She would often come to Katori's house, she studying and Katori playing videogames. When Somei was prohibited from visiting Katori, Katori switched her bedroom with her brother, since his bedroom faced Somei's, and opened a window in the wall so that they could talk. Katori tried to play it cool by pretending that she just wanted to rearrange her room, to no avail. After learning that Somei saved her instead of her own parents, and that her friend planned to enlist in Border, Katori decided to join with her, convinced that with her talent they would be able to achieve anything. Despite Somei studying much harder than Katori when they were younger, she was not bothered by her friend boasting about achieving superior grades with little effort, although she does warn her that she plans on climbing to the top of Border. On occasion Somei does chide Katori for not taking her duty seriously enough, but unlike Wakamura she never seems to prod her to improve, presumably because she knows that at the end of the day Katori will do what she wants. To this day she remains unfazed by her temper tantrums, her bluntness occasionally frustrating her. However, she encouraged her when she feared that she would not be able to improve, sensing that Katori was finally willing to make an effort. Somei is one of the few people who can make an emotional Katori listen to reason, whether it be while fighting or when she argues with Wakamura. However, she does not intervene in the arguments unless they directly affect the performance of the team. Katori and Somei are on a first-name basis, neither using honorifics.

Rokurō Wakamura
The demotion to the mid-tier of B-rank has exacerbated Katori and Wakamura's relationship. He is very outspoken in his criticism of her, sometimes excessively so, taking a harsh tone which causes her to respond back in kind. His calling her out on her detrimental lack of motivation before the match against Tamakoma Second sparked their harshest argument yet, with Wakamura pointing out that she would need to work hard before she can complain about there being nothing she can do, and Katori responding to his criticism first by mocking his skills, then by throwing her phone at him. On that occasion Wakamura seemed to acknowledge that part of his frustration with her is due to his own insecurities and envy. It is only after the fight that Wakamura realizes that Katori would actually like to work harder, but is afraid of being unable to do so. The two are on a first-name basis. Neither appends an honorific.

Yūta Miura
Miura has had an unrequited crush on Katori since he first met her, which may cause him to lose all willpower when speaking to her. He attempts to pacify Wakamura and her whenever they fight, although never with success. Despite rarely speaking his mind, he appears to know Katori very well, being the one who suggested that she might be feeling envious of Tamakoma Second. He addresses her by her first name followed by the diminutive suffix -chan.

Katori's mother
Katori's mother is aware of her daughter's intellect as well as personality flaws, calling her out on her arrogance, laziness, and attempts to look cool in front of Somei, although always in a very gentle, light-hearted way.

Katori's father
Katori is exasperated by her father's very public displays of affection for her and the openness with which he talks about feelings in general, especially her own. For his part he is unaffected by her rebuffing his affections and her occasional acting spoiled.

Katori's brother
Katori's brother did not hesitate to trade rooms with her to let her be closer to Somei when the latter was forbidden from visiting. Like the rest of their family, he can easily ignore Katori's tantrums and enjoys teasing her when she tries to put up a stoic façade.

Kyōsuke Karasuma
Katori has a very blatant crush on Karasuma.

Nozomi Kako
Katori seems to resent that Kako never tried to recruit her despite her fulfilling the A-rank captain's criteria.

Tamakoma Second
Over the course of their match Katori grew to despise Tamakoma Second, and in particular Osamu and Yūma. Osamu's response to her attempts to distract him - that he was simply doing what he believed he had to do - infuriated her, presumably due to her struggle with motivation and her own recent defeats. Her rage intensified when she grew convinced that Yūma and he behaved as if they were the main characters in a story. In reality, however, her hostility is due to a profound envy for the successful, hard-working newcomers.
