Dungeon Samurai

Yamada Yuuki is an ordinary college student devoted to the classical martial art of Kukishin-ryu. When a demon abducts everyone in his dojo to another world, he and his friends learn the only way home is to conquer a dungeon running through the heart of that world. Armed with steel, faith, and guts, they battle through winding catacombs toward the demon waiting at the bottom floor.

Six months after being spirited away, Yamada Yuuki and Hiroshi Matsuo must dive deeper into the world-spanning dungeon than any human has gone before. The monsters grow more dangerous with every floor, strange spells visit death and madness on the unwary, and an ocean of suffering lies between the humans and the bottom. To stand fast against what is coming, they must take on the mantle of the Kami no Kishi — the Knights of God.

The war for the dungeon reaches its climax. A hero has fallen, famine threatens humanity, and the monsters have grown even more powerful. All hopes rest on Yamada Yuuki — a college student turned battle-hardened samurai. Armed with faith, steel, and new tactics, he must lead a desperate crusade into the depths, where the dungeon itself is changing and the demon ruler waits on the bottom floor.
