Wistoria: Wand and Sword 7 (manga)

Regarden is left reeling after a host of monsters crashes the Terminalia festival. With the Magia Vander having exhausted all their magic repairing the Great Barrier, Will and the remaining mages are the Tower’s last line of defense. Yet, this enemy may be too much even for Will…unless the Icemaiden can give him the edge he needs.
