"Departure: Time of First Snow"

Kureha tells Kanata more about Princess Iliya, mentioning that she had originally planned to marry the Roman Emperor in order to improve relations with the Roman Empire. Yumina asks Kanata and Rio to check up on an old woman named Jacott who lives in the mountains. The two later take a walk where Rio talks to Kanata about her half-sister. As the snow falls, Jacott, filled with memories about her love, runs off into the snow and never returns. Rio reveals she is the half-sister of Iliya, and decides to leave the fortress to help improve relations between the warring sides in her place, leaving Kanata her trumpet.
