Character biography
She is known as the "Wicked Witch of Expulsion" ("Lynn, the Expelling Witch" in the English DDM game), since she expelled fifteen students in the last six months. In the manga, After a desk check, Chono asks who a love note in the form of a jigsaw puzzle to Miho Nosaka belonged to. Yugi Mutou (Yugi Muto), Katsuya Jonouchi (Joey Wheeler), and Hiroto Honda (Tristan Taylor) stood up, indicated that the puzzle came from each of them. Chono decided to finish the puzzle to determine who the gift is from. Dark Yugi (Yami Yugi) turned the gift into a Shadow Game. 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 true ugly face. The other students laugh at her. The gift was from Honda - When it was given to Miho, she rejected him.

In the anime, the gift was supposed to be from a girl named Mayumi to Jonouchi but Anzu Mazaki (Téa Gardner) 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. Again, her face cracks when she loses to reveal her ugly face. She later appears in episode 12 with Ryuuichi Fuha and again gets her face cracked.
