Initially, only seven
characters and their Digimon partners are available. During the third arc, the eighth character,
Hikari, becomes available. During the course of one episode, one character assumes the role of team leader and two other characters' Digimon partners join in battle. Occasionally, the team leader will be able to talk to the other characters mid-episode. By choosing the right answer, the relationship level between those two characters is increased. This has multiple benefits, like an assist attack in-battle and unlocking extra episodes after the main story. A battle is between a maximum of six Digimon, three on each side. By default, the player controls the Digimon of the team leader and can take manual control of the other partner Digimon through the strategy menu. It has a turn-based system wherein each Digimon can use a regular attack, use special attacks, use items, guard against an attack, or attempt to run from a wild battle. After completing a main episode unlocking the evolution, the Digimon can
digivolve in-battle into their Champion, Ultimate or Mega forms. This significantly increases stats. Evolution consumes special points (SP) and doesn't use up a turn. Post-battle, the Digimon revert to their Rookie forms. Occasionally (for example, during the first time a Digimon evolves mid-story), they evolve pre-battle. The evolution sequences from the anime were completely reanimated for this game, unlike the non-credit version of the opening movie of the anime which was only cropped to fit the 16:9 aspect ratio of a PSP screen. Furthermore, the remaining Digimon that didn't have their own warp evolution sequence in the anime are exclusively created for this game. These sequences are only shown once during the initial evolution, but can be viewed anytime from the library. ==Story==
