When I woke up, all I found was a room I didn't know, a crystal, and "me" with no memories. Dan wakes up as a dungeon master and uses his few points to summon ant monsters and expand the dungeon. Together with the ants that are increasing and evolving inexhaustibly, defeat the enemies that have wandered in, sometimes bring in friends, create an impregnable labyrinth, and find new happiness and daily life in the dungeon! The long-awaited comic version of the popular dungeon management fantasy from "Let's Become a Novelist"!
