Toka Yada

"“Reception and negotiation techniques… once we go out to society, wouldn’t these become our sharpest blades?“"

- Toka Yada

Tōka Yada is a student in Korosensei's Class 3-E in Kunugigaoka Junior High School.

Appearance
Yada has dark brown hair (brown in the anime) held up in a ponytail and presumably dark brown eyes (light purple in the anime). She also has the largest bust out of all the female students in Class E, her bust size is E.

Personality
She is the big sister of Class 3-E and one of the most enthusiastic students about learning the art of infiltration from Irina. She's been described as being adult-like and cool to the point that Kayano admits that she's attracted to her despite her huge bust.

History
It was claimed that she was dropped to class E because she once neglected a test because she had to nurse her sickly younger brother.

Plot
Yada debuted in Chapter 1, but didn't get the spotlight until Chapter 66. In Chapter 66, she helped the girls out of a tight spot by driving away some guys who were trying to flirt with them by pretending to be a mafia princess.

After the guys run off, she then states that the yakuza emblem she had was obviously a loaner which came from Irina. Kayano notes that she's always been the most interested student in Bitch-sensei's lessons, to which she replies that, while she doesn't want to use seduction as a means to accomplish things, she wishes to gain the necessary tools for negotiation and entertaining, as they would be the ultimate tools when going out into society, prompting the other girls to compliment her on her maturity.

Abilities
Knifework: She has the third best knifework on the girls side, along with Hinano Kurahashi and Rinka Hayami.

Infiltration: As one of the more enthusiastic students in terms of Irina's lessons, Yada has gained notable skill in grifting as shown in Chapter 66, when she successfully drove away two guys by pretending to be a mafia princess.

Negotiation: Thanks to Irina's lessons, Yada has become a skilled negotiator, and she's usually relied on by the class for the task.

Irina Jelavić
Along with Kurahashi, she's one of Irina's favorite students. They are the only the students who know about Irina's past and true personality.

Hinano Kurahashi
They are often seen together, and seem to be close friends.

Megu Kataoka
It was revealed in the official Character Book that Yada has a crush on her.

Kayano Kaede
She more or less figured that Kayano condemns big chests, but she’s been avoiding that landmine.

Muramatsu Takuya
In elementary school, Yada and him has been childhood friends. He once popped into the classroom in which she was learning piano, but very soon he gave up on learning, which she still remembers.

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. Ritsu remarks that Yada’s breasts have gotten bigger, by this point Kayano has signed off.

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.
