Mrs. Muto is Yugi Muto's mother. She appeared in both the anime and manga and appears to have a different personality in both. In the manga, she's aggressive and goes as far as hitting Yugi with a ladle. She is more calm, sweet and caring in the anime.
In the manga she told Yugi off for practicing precognition when it was time to go to school. She also made two appearances in the second series anime. Once was when Solomon Muto was in the hospital in episode 41. Her second anime appearance was in episode 50, where she confronts Yugi with her fears. Not knowing that Yugi was talking to Yami, she assumed that Yugi was talking to himself. The second appearance was removed from the dubbed version.
