Gameplay
Koma (meaning "panel") is the term for the characters that can be used in-game as assistance. Each koma uses anywhere from 1 to 7 squares of a Koma Deck appearing on the bottom DS screen. The deck has 20 squares (4 x 5) on which to place koma. There are three types: Help Koma, Support Koma and Battle Koma.
- Help Koma are only one square large. They either provide boosts or help players, but will not appear on the Battle Screen.
- Support Koma are two to three squares large. These koma will show up briefly on the battle screen to help the player - generally by attacking, blocking, restoring health, or other substantial means.
- Battle Koma are four to seven squares large, and fight throughout each round. These koma represent the characters that the player controls on the battle screen, and the player can switch between characters by tapping their koma in the Koma Deck similar to a tag battle.
The player can build and store up to ten Koma Decks, and each deck must have at least one Help Koma, one Support Koma, and one Battle Koma to be valid for use in battle. Ally boosting is done by placing koma next to each other in the Deck Maker. If the koma placed next to each other are "compatible", their attributes will go up, providing small bonuses. Battle characters can receive a longer health bar, or increase the maximum number of special attack gauges.
