Playful and mischievous, Michiko Saeki is a first year at Tsuchiya Girls High School. If you want to have some fun, she's the one to go to. She is always up to something, and will take any opportunity to cause a scene. While she's quite annoying to Misa at times, she's been dealing with her antics for years, so she's gotten used to them. Jiyuu on the other hand, engages in her jokes, and finds them hilarious even if they're not funny. She has a soft spot for Jiyuu and tries to cheer her up when she's down. While she's a troublesome girl who only sees life as a game, She truly values her friendship with SynthBeat, and shows it in her own unique ways.
