Toka Yada/Relationships

Irina Jelavić
Along with Kurahashi, Yada is one of Irina's favorite students. They are the only the students who know about Irina's past and true personality. She’s a companion who knows Irina’s phone number. Yada and Irina's relationship feels like one between friends moreso than teacher and student, and they’re planning to hold a hotpot party in the coming winter.

Kayano Kaede
Yada is somewhat aware of Kayano's condemnation for large chests and as a result, avoids it. At Okinawa, she was moved by Yada’s views on self-improvement. In Kayano’s mind, even when they stay silent, girls with huge chests will still have high levels of femininity, which is almost like cheating. But that view has begun to change. In a tankobon extra, Yada and Kayano are shown to be good friends, although the latter still harbors an aversion to her large bust.

Shiota Nagisa
When Takaoka was one-sidedly pummelling on Nagisa (at Okinawa), she couldn’t help but turn away from the scene. She hates blood and gore, which is why she’s committed herself to perfecting her negotiation skills in order to avoid fighting.

Muramatsu Takuya
Yada and Muramatsu were childhood friends in elementary school. He once popped into her piano class, but he quit, which she still remembers.

Meg Kataoka
Yada had a brief crush on Kataoka, but it has since ended.

Okano Hinata
She had already noticed how Okano feels about Maehara very early on, and has been rooting on her from the side. But Maehara hasn’t noticed this at all, so she’s feeling pretty dissatisfied. Yada is a member of her Field Trip group with whom she has good relations. She has mixed joy and envy towards her bust size. Okano refers to her as "Yadacchi".

Hinano Kurahashi
Yada and Kurahashi are close friends and as a result, are frequently seen together. A notable example was during an effort to infiltrate Japan's space station, they distracted the guards by pretending they were lost. They both have gentle and quiet personalities yet still have pretty high girl power, should any average boy look down and flirt with them, they’ll be peacefully, verbally cornered into silence before they even notice.

Taiga Okajima
Okajima has his eyes on her, but because he has no immunity against a real girl’s body, they have not reached a stage of being in (any physical) contact with each other.

Rio Nakamura
The two of them are sometimes seen together and are usually together in a group. Rio refers to Toka as “Yada-chan”. In one of the tankobon extras, Rio is seen trolling Yada and Kayano in the 3-E girl group chat by telling Yada her breasts have grown bigger to which the the latter denies.

Masayoshi Kimura
For some reason they get paired together into the same group a lot, and although they have good dynamics going between them in class, in the end he has no special feelings towards Yada.

Rinka Hayami
A fellow appreciator of dancing, if there’s (standby?) time available, they’ll meet up and dance some steps without saying a word.
