Digimon Battle Spirit 2 is a licensed fighting game that's based on the Digimon franchise. It was originally developed for the WonderSwan and was later ported over to the Game Boy Advance when it was released overseas. The game's story and characters come from the anime Digimon Frontiers, and the gameplay itself is mostly the same as with the previous game. Digimon are summoned to fight each other where the objective is not to reduce the opponent's HP to zero but to damage them enough that they drop orbs. Whoever collects the most orbs by the time the round is over is the winner.
KusogeMan in this run chooses Kazemon for her versatile moveset and beats Cherubimon/Kerpymon as fast as possible while exhausting what little story the game could adapt from the anime at the time.
