Toka Yada

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

- Toka Yada

Toka Yada (矢田 桃花) is a student in Korosensei's Class 3-E in Kunugigaoka Junior High School.

Appearance
Yada has brown hair held up in a ponytail and light purple eyes. She also has the largest bust out of all the female students in Class E, a trait inherited from her grandmother.

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 large bust.

History
She was sent to Class E for neglecting a test in order to nurse her sick younger brother. This backstory would later be used as a means to escape jail in a game of Cops & Robbers.

Plot
Yada didn't get the spotlight until Chapter 66, where she helped the girls out of a tight spot by driving away a few thugs who were trying to flirt with them by pretending to be a mafia princess.

After the men 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 Irina'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, making the other girls 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 swindling, as shown when she successfully drove away two thugs away by pretending to be a mafia princess.

Negotiation: Thanks to Irina's lessons, Yada has become a skilled negotiator, and she is 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
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.

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

Kayano Kaede
Yada is somewhat aware of Kayano's condemnation for large chests and as a result, avoids it. In a tankobon extra, Yada and Kayano are shown to be good friends, although the latter still harbors an aversion to her large bust.

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.

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.
