"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.


  • 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?).
