Akiko wears the default uniform of the academy and red stockings with pink that match her panties. She has maroon/red hair. She has bangs and buns with ahoges and long straight back hair. Her eyes are brown with a tint of light brown and her bust size is 1.2. Her eyebrows are thicker and the shape of her eyes give her a gentle look.
She is very shy, she is a coward. If she sees Yandere-chan killing or carrying a body, she will beg her to don't kill her. She'll swear to do not call the police. As a coward, she will cover her face with her hands if Ayano put the camera on her.
Arrived at 7:00 A.M. with other students, she walks to her locker. At 7:15 A.M., she goes to the courtyard, sits on a bench and reads her book. She often stalks other students. In Wednesday, she stays in the Photography Club all day so she can't talk with her friends.
She goes to her classroom (2-1) at 8:00 AM to 1:00 P.M. Then she leaves school at 4:30 P.M.

- Her name means "shy" (Shai)
- She joined the Photography Club just for secretly taking pictures of other students without looking like a creep.
- Like Yandere-chan, Akiko has got a shrine in her bedroom but with stuff from other students.
- She used to look like a total copy of Mai Waifu.
