The following character is a canon character.
Please refrain from adding fanon infomation (Eg. Fan-Made Personality, Fan-Made backstory, Fanon Relationships, ETC).

Mei Mio is one of the second-year students at Akademi High School featured in Yandere Simulator. She is one of the first 12 students to be added into the game.

Presently, she is a member of the Cooking Club, however, YandereDev has stated that this isn't final.


Mei Mio, by default, wears the white sailor uniform, unless otherwise customised by the player. She also has blue stockings with matching blue panties, a blue friendship bracelet on her wright wrist, as well as blue framed glasses.

Mei has indigo blue hair with bangs falling on her face worn in a small bun. There's also an ahoge sticking out from the top of her head. Her eye colour matches her hair colour. Mei's bust size is 1.4.


Currently, Mei Mio has the Teacher's Pet persona. If she witnesses murder or finds a corpse, she will report it to her homeroom teacher. Mei reacts to a camera pointed at her by giving a supsicious look.


  • Mei's hairstyle before the February 8th, 2016 Build was changed because YandereDev thought that her previous hairstyle was "low budget" and "amateurish".
  • Along with Ryusei Koki, Mei is the only one in the Rainbow 12 group to have the "Teacher's Pet" trait.
  • Originally, Mei Mio's name was Tsumu Kotobo.
  • Like all other students, Mei Mio recieves a different appearance in the Lovesick Mode. In it, Mei's indigo colours are replaced with black - her hair, eyes, stockings, panties, friendship bracelet and glasses are all black with a very slight tint of blue.
