The secretive and proper workaholic president of the student council. The way she carriers herself implies experience that she actually doesn't have.
Reticent and secluded as well as extremely work oriented. Appears to most as cold or distant, and more recently even a bit callous. As the rest of the student council is incompetent, their duties are almost always pushed on to her. Still, she carries them out without complaint.
Her family has been spotted moving between Solumthorne and Flashport quite a lot, but it's unclear why. They seem like wealthy people, so their business in Solumthorne is subject to many rumors.
Alice was a great help to her when she first joined the council, so Ruma has always looked up and felt eternally grateful to her. She may have grown less emotionally available as a result of her idol’s disappearance.
Relationships:
Aromé - She's not good at communicating it, but she's grateful for the help he tries to offer. She's also greatly burdened whenever he gets distracted and forgets about working, but never holds it against him.
Kyadi - Often pestered by her, but that's mostly because they're curious about each other. They're very close, and whenever Ruma is free they grab a meal together (with Ruma always paying). When they're doing student council work however, Ruma hates how much trouble she causes.
Cypress - Thinks he's worth investigating but he's not exactly worth much of her time right now.
Leveret - Close friends. She knew him since before they transitioned and is impressed by how much they grew since then.
Shrei - No thoughts. Just another noisy guy.
Aka - Thinks she's incredibly suspicious, but also acknowledges it's important to do work with her. Ruma is confident she can use her to uncover clues about Alice's disappearance as long as she doesn't antagonize her too early.
Alice - She was in the student council previously when Alice was the president. She looked up to her a whole lot, and was also one of the few people she could confide in. When she disappeared, Ruma was the most hurt by it.
S3N - Thanks to Aka, she has it installed on her smartphone. It's helped her a whole lot with organizing files and other work. She completely ignores its playful personality though and instead uses it completely as a tool. The fact it looks like Alice bothers her.
