Serene's basically a homebody who rarely ventures outside her dorm, though she did manage to go on a trip with the group—apparently Koushi gave her the push she needed. She's got this mysterious, laid-back vibe that most people find pretty approachable, despite how little she actually interacts with others.
Her dorm room is basically a disaster zone, but she's convinced the piles of junk are actually items that absorb lunar energy for her various moon-tech projects. Whether that's genuine belief or just how she justifies never cleaning is anyone's guess. Either way, she doesn't seem bothered by it. Her easy-going nature means she rolls with whatever happens without much fuss.
