"I'll defeat you... and take the top!"
―Coby's declaration to Salt(src)

Coby (こびー Kobii?) is a character in Majisuka Gakuen 4. She is a third year student of Gekioko Koko, and the Vice-President in Antonio's Nursing Department.

She smiles when beating people up, showing her sadistic nature. This has instilled fear of Coby among her underclassmen.

Coby, along with Antonio and the rest of the allied schools who died in the war, appeared as a vision to Miyawaki Sakura, and joined her last stand before being shot to death by the police.


  • Kobi (媚び?) means flattery, which Coby's actress (Watanabe Miyuki) is known for using on her fans.
  • Coby's favorite phrase, "Jabu Jabu" (ジャブジャブ Jab-Jab?), was taken from her actress' favorite phrase, "Chapu Chapu" (ちゃぷちゃぷ?), that was also derived from "Jabu Jabu" (じゃぶじゃぶ splashing sound?).
