Satowa's a first-year student from the prestigious Houzuki koto family—basically koto royalty. She's been playing since childhood and has racked up contest wins, so she's genuinely talented. The weird part? Despite being a prodigy, she got kicked out of Houzukikai, the family's own organization.
Her reason for joining the school koto club is pretty specific: she wants to make a name for herself as the "young virtuous koto player who took a nobody school club all the way to nationals" when she goes pro. It's an ambitious goal, but fans often note it shows she's not just coasting on her family's reputation. She's genuinely passionate about koto—that much is clear—and she seems determined to earn her own legacy rather than just inherit one.
