Clay

The protagonist of this work. A thief and explorer registered with the Thieves Guild of the Anthill. At the beginning of the story, they had conquered up to the 8th floor, but now they have reached the 10th floor (though it is an unofficial record since they are not registered with the Adventurer's Guild). While exploring the dungeons of Anthill, they were recruited by Belle, the dungeon keeper, to work inside the dungeon (rumors within the dungeon say that they were tamed and started helping with the dungeon's management after losing to Belle). Among the dungeon's monsters, they are nicknamed "Mr. No Friends".
