Mimas Chan is a 18 year old girl who is part of Saturn's friend group, a group consisting of Saturn Chan's "Moons". Like Enceladus chan, Mimas Chan is close friends with Saturn Chan, but even closer friends with her than Enceladus Chan is due to Mimas orbiting closer to Saturn than Enceladus does. She is usually shy and reserved around the other moon chans and planet chans, but she is very outgoing with other people. She is the smallest of the moon chans, being only 4'7 tall!
