The Dark Heart of Friendship

'''Bokomon recognizes the mysterious structure as Sakkakumon, Mercurymon's Beast Spirit. Each of the warriors now wanders alone in a different sphere, and Tommy and Koji are forced to contend with their own reservations regarding friendship.

Summary
Tommy finds himself in the volcanic Flame Area, separated from the others, all of whom have found themselves in their own worlds. As he begins to search for his friends, while dealing with the memory of the harsh words his brother, Yutaka, said about Tommy and his dependence issues, he is attacked by a three-faced Digimon. As he runs away, unable to find time to spirit evolve, another Digimon, appears and fends off an attack. He befriends Tommy and promises to help him find the other DigiDestined, with Asuramon giving him aid. When Tommy wants to stop, however, Asuramon goads him with saying that he has done Tommy favors, but Tommy refuses to believe friendship is based on that. Asuramon grows angry and reveals himself as the Digimon who attacked earlier; Tommy, taking strength from Yutaka's lesson that friendship is based on give and take rather than just take, defeats Asuramon and frees himself.

Meanwhile, Koji finds himself in the Wind Area. As he explores, he realizes he is being followed by something and encounters, who mocks him, saying he is unfit to be the Legendary Warrior of Light and demands his spirits. Koji spirit evolves and the two fight, Karatenmon continuing psychological warfare with his attempts to crack Koji's exterior. When Karatenmon pokes at Koji's relationship with his stepmother, it angers Koji enough to defeat him. The world darkens around him, and another eye portal opens for him, taking him to another world.
