Mikoto Aketa

She is the oldest idol in 283 Production, and also the first idol to transfer from another production. She moved to Tokyo from Hokkaido at age 14 in order to pursue singing, and joined another office as a trainee. There, she fell in love with the concept of idols, and decided to become one. She worked extremely hard, to the point she says she "barely has memories of high school, just being in the lesson room", but she was unable to succeed beyond some slight success. She originally was part of a two-member unit alongside Luca Ikaruga before they disbanded due to a fall out. Eventually she transferred in order to become her ideal idol.

She's calm and collected but has intense feelings towards being an idol, and is an extreme workaholic, often practicing until dawn.
