Overview
Taking place on Valentine's Day, 2003, the audio drama starts with Davis trying to change his image so girls will like him by imitating various DigiDestined. Kari, Mimi, and Sora are kidnapped by Boltmon who just wants a heart. Pukumon had taken advantage of this in order to destroy the DigiDestined. Ken's Pucchiemon reasons with Boltmon, and the kids subsequently fight the mastermind, Pukumon. Joe knocks into them, and they drop and mix up their D-Terminals. This causes them to use the wrong Digieggs and Digivolve into new Armor Digimon, who beat Pukumon. Overall, the story serves to provide light humor. Also, this drama marks the first time that the Digidestined are able to use their Digi-Eggs interchangeably, and transform their Digimon into new Armored Digivolutions using each other's eggs.
