Dungeon & Slave ~The Guard and Students’ Harem in the Succubus Dungeon Tester~

Sanada Yoru, a scarred high school guard haunted by a childhood stolen by terrorists, thought he’d finally found peace patrolling the gates of a quiet Japanese academy. Then darkness swallowed them all. Awakening in the depths of a succubus dungeon, Yoru and his students face a cruel trial: the men must conquer monstrous floors as testers for an alien invasion, while the women—classmates, teachers, beauties one and all—are auctioned as slaves, their fates sealed by glowing ink tattoos of absolute obedience… or merciless disposal. Armed with battle-hardened instincts and unyielding resolve, Yoru fights alone, claiming his harem one bloody victory at a time. But as creampie bonds deepen and otherworldly temptresses join the fold, can he conquer the dungeon’s heart—and save them all? — Description from novelcodex.orgFull novel: Dungeon & Slave ~The Guard and Students’ Harem in the Succubus Dungeon Tester~ — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
