Ms. Chono, known in the English version of the Dungeon Dice Monsters video game as Miss Lynn Madusa, is a teacher at Domino High School. She is known as the "The Wicked Witch of Expel" ("Lynn, the Expelling Witch" in the English DDM game), since she expelled fifteen students in the last six months. Her beautiful appearance is due to the immensely thick layer of makeup she wears, which covers her true, ugly face. She also enjoys dating, but the part she likes the best was to dump the men to see them cry. Typically, she is an extreme sadist.
In the manga, Ms. Chono was furious about getting dumped by a man she dated, before she got a chance to do the other way around, and decided to vent her anger on the students with a desk check, hoping to see them scared and finding a chance to expel them for finding "cool" things such as cigarettes, lipsticks, and condoms. She found a love jigsaw puzzle on Miho's desk, and asked who it belonged to. She claimed that if the sender confesses, she may forgive him (though it was a lie, as she planned to expel the sender anyway). Yugi, Jonouchi, and Honda stood up, and indicated that the puzzle came from each of them. Chono decided to finish the puzzle to determine who the gift is from. Dark Yugi turned the gift into a Game of Darkness. The more she works the puzzle, the more her face starts to turn into pieces. When she finished the puzzle, the pieces from her face appear - her beautiful face shatters, revealing her ugly face. The other students laugh at her. She ran out of the room, stating the class never happened, and she would get anyone who expose her secret.
In the anime, the gift was supposed to be from a girl named Mayumi to Jonouchi but Anzu actually made it as Mayumi didn't know what to give Jonouchi. When Anzu complains about the strictness of the school, Chono asks Anzu to collect signatures from other students in a petition asking for laxer rules. Chono then orders some boys to rip up Anzu's signature paper. Dark Yugi challenges Chono to a game involving two mirrors and being blindfolded. Her face cracks after cheating (she took off her blindfold during the game) to reveal her ugly face.
She later appears in episode 12 with Ryuichi Fuha and again gets her face cracked.
