Ritsu is a second-year high school student living in the dorm alongside Usa. She's the quiet type—you'll usually find her with her nose in a book—but don't mistake that for social anxiety. She's actually pretty content being on her own, even if people assume otherwise. Her grandfather happens to be the brother of the dorm's landlady, which makes her family in a roundabout way. Because of that connection and her responsible nature, the landlady trusts her to keep things running when she's away. Ritsu's fine with the solitude, though she'll push back if anyone suggests she's lonely about it.
