Granblue Fantasy, Volume 6 (Granblue Fantasy #30-34)

Upon releasing Yggdrasil from the sadness that had driven her mad, Gran and the crew head to the Albion Citadel to "make amends" with General Furias. There, they meet Vira - the young and beautiful Lord of Albion - who was Katalina's junior at the Albion Military Academy. While this reunion brings Vira joy, Katalina has never been so distressed. Still, no matter what haunts Katalina, the crew knows they must conquer those demons together.
