Miyumi smiling kindly as she greets the Mystery, Inc. gang

Miyumi is the main heroine of Scooby-Doo and the Samurai Sword.

Physical appearance

Miyumi is a female, with dark hair held in long pigtails. Her main outfit looks like a school uniform, consisting of a maroon blazer with a white shirt, a purple tie, an orange and yellow badge, violet boots and skirt.


Miyumi was at first loyal towards her master and oblivious to her true colors. The reason Miyumi sided with her master was because she was tricked into thinking that she would be closer to Daphne if she worked with Miromoto. When Daphne convinced Miyumi that she was being used, she saw the error of her ways and sided with Mystery Inc.

Scooby-Doo and the Samurai Sword

Miyumi is a friend of Daphne Blake's. She comes from Japan and serves in a karate school with Daphne. Miyumi meets Scooby-Doo and the Mystery Inc. gang when they come to Tokyo and aids them on their journey. She serves under Miss Mirimoto, the conniving head of the karate school, but later in the film refuses to sell out her friends. In the finale, Miyumi disobeys Miss Mirimoto and helps Scooby-Doo and his friends by stealing the Black Samurai's sword. She honors Scooby-Doo after he defeats the Black Samurai and becomes a legend.


  • Miyumi is voiced by Kelly Hu, who also voices the evil Miss Mirimoto.
  • She dreams of becoming one of the Mystery Inc. gang one day.
