While looking for a way back home, J.P. and Tommy run into a lot of Pagumon who chase them down because of J.P.'s chocolate. They fall into an underground labyrinth where Koji Minamoto rescues them, but one Pagumon digivolves into a Raremon. Takuya digivolves to Agunimon, but is suddenly changed back before he can finish Raremon off and knocks Koji down a hole. Koji finds the Human Spirit of Light, Lobomon, and prepares for the true fight. After a battle Lobomon defeats and destroys Raremon and the remaining Pagumon flee. Koji thanks Takuya for saving his life, but is rather rude to him.
