Kira reincarnates as Danmachi

In a dark room, Light Yagami opens his eyes. His mind is confused, and memories of his previous life vanish like smoke. However, one certainty remains: he is not in the world he knows. He sits up and examines his surroundings. The stone walls and dim light suggest an underground place. A dungeon? A prison? I Do not know. The only thing he remembers and knows is to create a “new world” by eliminating criminals and those he considers a threat to society.
