Chise attends her first day at the College with Elias in tow.

After returning from camp, Lucy is still unconscious and it's still not clear what's behind her sudden loss of strength...this worries Chise deeply.

Apparently, a forbidden magic book called "The Testament of Carnamagos" is being used to rob Lucy and Simeon of their magical powers. But who exactly is behind it is still unclear. Elias takes care of the matter because he fears that otherwise Chise will put herself in danger for her friend and because he himself wants to protect a friend.

It's time for family explanations, whether between Lucy and her brother, or Alice and Renfred. The College is also going through a complicated period where other magicians seem to want to harm new students.

The College is sealed off to protect the students and staff from whatever or whoever has been sapping magic from victims. Zaccheroni puts the students' survival abilities to the test, but with a catch: no sorcery allowed.

Outside the College, the witches hunt for the missing book. Inside, the students try to juggle lessons with their own personal goals and relationships. Philomela confides in Alcyone, but an ominous message reminds her of her assignment.

The mystery deepens as all the students drained of magic suddenly wake up feeling fine. Rumors about the culprit start to rise among the student body. Veronica checks in on Philomela.

Despite their disappointment that the College will be closed through Christmas, the students try and prepare for the holiday party. Chise takes another dive into Lucy's memories. Philomela reaches her breaking point.

Philomela bargains for Liza to undo the seal over the College so she can return home to fulfill her duty. As Chise gives chase, her power gives her a terrifying new form.
