Ms. Chono (蝶野先生 Chōno-sensei) is a character in the Toei Yu-Gi-Oh! anime. She is the anime incarnation of Ms. Chono, from the Yu-Gi-Oh! manga. Ms. Chono was a teacher at Domino High and whose beauty is a strong talking point among male students and teachers. Her beauty is due to an immensely thick layer of make-up, which covers her true ugly face. She enjoys dating, as it gives her the chance to dump men and see them break down. Chono is strict and regularly attempts to get the rules upgraded to stricter terms which would include the banning of all personal items and an increase in punishment for violations.
