One of the Black Dogs' second-year prefects alongside her twin sister Kochou, Teria is the dorm's go-to person for anything mechanical or engineering-related. She and Kochou are only 14 despite being second-years—they skipped grades thanks to their sharp minds, though Teria's main reason for enrolling was honestly just to stick with her sister.
Naturally shy and reserved, Teria doesn't exactly seek out the spotlight. Still, she's got backbone when it counts and will push through her anxiety to help someone in need. As Romio starts taking her under his wing and offering genuine support, she gradually develops feelings for him. Her sister notices, of course, and doesn't hesitate to nudge Teria toward being more direct about it rather than just quietly pining from the sidelines.
