Chise was able to accept Elias and herself, if not necessarily everything about her situation.

Then she receives an invitation from a mutual aid organization for mages called the College. Under the British Library exists a secret society of mages. Encounters and interactions with people are about to open some new doors. This is a story about saving yourself to save another.

Note: Episode 1 of season two premiered in a preview screening event together with "Fuyu no Okorimono" at Tachikawa Cinema City's Cinema Two in Tokyo on March 11, 2023.

Just prior to Chise becoming a part-time student, during Cartaphilus' brief nap… Chise receives an invitation to the academy, and she, with the help of Elias and the others, begins preparing. One such busy day, a spriggan arrives at their home on a strange horse, bringing news that "something is wrong with this Wild Hunt." Gabriel, an ordinary boy who'd just moved from London, was bored. Of his situation, of being parted from his friends, of unfamiliar land. Of everything. He was staring through his window, as if to escape from it all, when he caught a glimpse of tobacco smoke. When he ran outside to chase it, the impossible happened: his world began to intertwine with the veiled world of the mages.
