Aiko Sato

a freelance amateur writer with her pseudonym the part-time assistant manager of Miyako Shiba at Stray Beat,She is also the assistant manager of Kessoku Band since Miyako signed them and became their manager. Aiko makes effort to cover her real age with long black bunches of hair and purple eyes although she is currently 23 years old. Her neck is also wrapped with a bandage-like ribbon. Her fashion styles mainly resembles Yami Kawaii subculture of Harajuku fashion. There's a small running gag that she's actually flat chested but because she wears such a large sleeve shirt it's hard to tell for sure. She has a strong interest of music and bands, as shown from how she do her job as a freelance writer. She strives to find good bands so she may highlight them in the blog she is working in. She also has sharp senses to be able to judge on the bands she is listening to. While her job as a writer requires her to be able to find news scoop everywhere and comment critically on bands, sometimes she tend to be carried away by her interest and job that she ended up causing troubles on places she go to do her work, like infiltrating Bocchi's school and interviewed students without permission and criticized Kessoku Band openly after their live that she was kicked out from STARRY afterwards. However she is still able to carry good judgement when she is under control and give encouraging comments. One thing she is sensitive with is her identity, as in the blog, she works under the alias "Poison♡Yami". She is not willing to let her real identity leaked in the web and even when doing her writer job outside, she still introduces herself with her online name and uses fake age so she will not expose her true identity to others. With her childlike look, people will not suspect much of her real age. She secretly extremely hates bugs that she will immediately jolt up and get away from it.
