"Suppose you visited an early dungeon but encountered three final bosses?" is the ninth episode of Suppose a Kid From the Last Dungeon anime adaptation.
A large snake appears in a dungeon near the kingdom of Thistle, and the candidates go to subdue the large snake at the request of the king. Lloyd, who is not good at dungeons, also goes to subjugation with his friends as part of his training. At the same time, Alka and Marie also pursued Sou and Shoma, who were aiming for the snake, and headed for the dungeon, where Mikona, who had taken a dubious drug, was burning a flame of revenge on Lloyd.
