Zero Damage Sword Saint: I Enrolled in a Magic School and Wound Up in a Contract with the Demon Queen: Volume 5

After dealing with the Last Dungeon, Babel, both Eugene and Sumire are now students in the prestigious Hero Course at Lykeion Magic Academy. Their peaceful days come to an abrupt end when he and his classmates receive a major request: to slay the Infernal Demonic Beasts in the Blue Sea Union and the Cardia Halidom. Though Eugene, Sumire, and Sara accept the mission, they learn that slaying an Infernal Demonic Beast places a curse on the slayer, condemning them, their loved ones, and their family to death! To make matters worse, the Fiend Dragon Glasya-Labolas—the oldest and most powerful of the Infernal Demonic Beasts—launches a sudden attack on humanity. To carry out the mission and defeat the Fiend Dragon, Eugene must take drastic measures.
