Tower Dungeon

Tsutomu Nihei departs from his cyberpunk roots to craft Tower Dungeon, a dark fantasy manga serialized in Kodansha's Monthly Shōnen Sirius since October 2023. The narrative centers on Yōji, a farmboy drafted into the royal army after assassins kill the king and abduct Princess Ignelia. She has been taken to the Dragon Tower, a colossal living structure that functions as a shifting labyrinth filled with mechanical traps and grotesque monsters.

This story operates as a relentless survival mission rather than a traditional hero's journey. Yōji and his knights must ascend the tower's infinite floors while battling biomechanical horrors that defy conventional architecture. Double-page spreads emphasize the crushing scale of the environment and the inevitability of death, creating a grim tone often compared to Berserk. The series prioritizes atmospheric tension over deep character introspection.

Vertical Comics released the English translation starting in July 2025, with five volumes available by early 2026. Critics have praised the successful adaptation of Nihei's architectural vision into a medieval setting, noting its unique blend of high fantasy and gritty survival mechanics. By August 2026, the series had surpassed one million copies in circulation globally. [편집]
