Shez arrives at Garreg Mach Monastery, where they are brought before the Archbishop Rhea. Rhea allows them to enroll in the Officer's Academy as a student in the house of their choice. Afterwards, the fencing instructor Jeritza takes charge of Shez's house. If Shez chooses the Black Eagles, Edelgard and Hubert have a private discussion where Edelgard resolves to perform a miracle and rescue an unidentified "her", much to Hubert's worry. Regardless, Shez's monthly mission is to mop up the survivors of Kostas' bandits.
The students arrive at a fortress that has been co-opted by the bandits as their hideout. Shez and their companions wipe out the bandits. Afterwards, Jeritza orders them to search the basement, and they discover a captive Officer's Academy student. A mysterious third faction appears and attacks the students, but they are able to defeat their commander Kronya and her Demonic Beast and escort the captive to safety.
Afterwards, the captive introduces herself as Monica von Ochs, a member of last year's Black Eagles who was abducted shortly before her graduation. When Alois arrives to bring the students home, Monica accuses the monastery librarian Tomas of being her abductor. The party heads home, and the Knights of Seiros' investigation of Tomas turns up evidence supporting Monica's accusation. Shez witnesses the Knights attempt to arrest Tomas, but Tomas uses powers similar to those granted by Arval to drop his disguise and flee.
