A freshman at Domino High School, Miho is not a very bright girl. Though she is very cute at times, she can be quite annoying because of her perky persona. She spends the majority of her time checking out guys, just like all other girls. She is totally clueless about Honda's feelings toward her and considers him a trusted friend.

An interesting fact about Miho is that she originally did not appear as an addition to Yugi's group in the manga series. She only appeared once in the first volume, battle seven. Her addition to the group in the anime series is possibly for comedy relief seeing what she makes Honda do.
