Serene is quite mysterious and docile. She usually doesn't leave the dorm unless she goes to school, but with Koushi's help, she managed to leave it and go on a trip with everyone. Her room is filled with trash, but she calls them items which can suck the moon energy which will help with her lunar technology. She also got an easy-going personality.
