Michi Edogawabashi is a quiet and mature first-year at Yuraginozaka High School, often perceived as mysterious due to her concealed emotions and unpredictable behavior. She dislikes being the center of attention. Petite at 145 cm tall and frequently seen with pigtails, her theme color is orchid. Her closest friends are classmates Kaoruko Nijouin and Yuina Machiya.

Michi's primary hobby is meticulously crafting clothes for dolls. This passion becomes crucial when her favorite anime, "The Rosy Maidens," is infected by a memory-eating virus, causing her friends to forget it. Distressed, Michi travels into the anime world with Kaoruko and Yuina to confront the virus, finding the characters now dressed in tracksuits. To demonstrate the intended designs, Michi dresses as one character, leading a doll character to take her into a dream world. Her friends must rescue her, recalling how "The Rosy Maidens" strengthened their friendship. After defeating the virus and restoring the characters' appearances, the girls host a themed café event.

In battles against viruses threatening fictional worlds, Michi wields a scythe. She prefers relationships with those who show her kindness, reflecting her reserved yet appreciative nature.
