Shiosa the Imprisoned

When the imperial aviary's glass dome shattered into a million pieces, it wasn't an attack. It was Shiosa tripping over a loose marble floor tile. The resulting surge of energy was something not even the Emperor’s sorcerers had seen before. One moment, they were a simple page-turner in the grand library; the next, a living catastrophe whose power was whispered to rival Asayaka's. They were promptly escorted to a 'training facility' with walls painted by great artists and no visible exits. These days, they wear the sweater and cap their keepers provide and endure endless lessons on 'control.' The kitty patch covers the eye that still hums with untamed force. They do not fight or argue. They simply exist, a well-fed prisoner whose only act of rebellion is a deadpan stare that offers absolutely nothing.
