If you chose Agumon in the beginning, complete Item Road on Hard mode after you complete the game. If you chose Veemon or Guilmon in the beginning, you can get him by going on the Booster Pack Collection sidequest set by the Digi-Elfs in the Terminal Area and completing the dungeon with only 1 HP, without recovering your HP or using a Gate Disk. This must be done on Hard mode. If you chose Dorumon in the beginning, complete Item Road on Hard mode after you complete the game and collect twenty items. Note: You may need to do this on all Item Road quests on Hard mode.
