Description
Toka Yada is a student in Class 3-E at Kunugigaoka Junior High School. Her brown hair is typically tied in a ponytail secured with a red elastic, complementing her light purple eyes, and she stands 161 cm tall. Inheriting her grandmother's traits, her physical development includes a bust size among the largest in her class, measured as an E cup during her teenage years; she expresses concern about potential further growth being unsuitable for her age.

Yada exhibits a mature and composed personality, often regarded as the "big sister" of Class 3-E. She dislikes violence and prioritizes negotiation and diplomatic techniques for conflict resolution. Enthusiastic about learning infiltration, reception, and negotiation skills from her teacher Irina Jelavić, she views these as essential for a future business career. Yada emphasizes honesty in expressing feelings and aims to leverage interpersonal skills rather than seduction.

Her placement in Class 3-E resulted from neglecting a critical academic test to care for her seriously ill younger brother. This backstory later aided her during a "Cops & Robbers" game, where she used it persuasively to escape confinement. On a summer trip, she demonstrated negotiation abilities by impersonating a yakuza princess to deter harassers, utilizing a borrowed emblem from Irina.

Academically, Yada excels in Japanese but struggles with mathematics; her exam rankings fluctuated between 32nd and 92nd place in class standings. She was a member of the Girl’s Tennis Club before joining Class 3-E and maintains skills in piano, tea ceremony, and tennis.

In assassination training, Yada develops proficiency in marksmanship, knifework (ranking third among the girls), acrobatics, parkour, and bilingual communication in Japanese and English. Tadaomi Karasuma evaluated her aptitude with strengths in politics/negotiation (6/6) and scouting (4/6), and weaker scores in technical traps (1/6) and leadership (2/6). She is recognized as Irina’s second-best student in kissing techniques.

Yada shares close bonds with classmates: she admires Irina Jelavić as a mentor and friend, communicates with her outside school, and supports Irina’s romantic pursuits. She harbored a past crush on Megu Kataoka and maintains a friendship with Hinano Kurahashi, collaborating on negotiation-based missions. She also notices but discreetly supports Hinata Okano’s feelings for Hiroto Maehara. Her codename, "Ponytail and Chest," originated from Taiga Okajima.

After high school, Yada attended Midoriyama Gakuin University, where she was entered into a beauty pageant without consent and became a finalist. She later reunited with classmates during a Class 3-E reunion.
