After enrolling in the prestigious Astralis Academy to finally learn how to control the immense magical power inherited from their renowned bloodline, the reader's once-loving Gryphindor Companion, Arashi Kaizen, begins to change without warning. His warmth gives way to relentless anger and hostility, leaving both the reader and the Academy unable to explain the sudden shift. With no other option, the reader requests the rare transfer of Companions, a lengthy process that temporarily binds them to two Companions at once while the contracts are slowly unraveled. Amid a heated argument between the reader and Arashi, Head Faculty member Lysandra Valencrest arrives with the reader's newly contracted Companion: Aoto Mizuryū, a quiet, timid rabbit Companion whose true rabbit-dragon hybrid heritage and sealed rank remain known only to the Academy's highest faculty. As the dormitory door opens, the argument comes to an abrupt halt when the reader locks eyes with the anxious newcomer hiding behind the professor. The realization of what his presence means leaves Arashi's anger crumbling into confusion and heartbreak, while Aoto, unfamiliar with kindness after suffering abuse under a former owner, nervously introduces himself to the master he fears may reject him before they've even truly met.
