Arriving in the Heaven Zone, Xros Heart are approached by Beelzemon while in awe of their suroundings. Taiki unknowingly falls off a cliff when he is sudddenly saved by Shakkoumon. Dondokomon suddenly drums himself disrupting a Pucchiemon orchestra causing him to get in trouble with a Piximon who is a member of Zone's Police Force. Dondokomon retaliates by tacking Piximon, resulting in reinforcements. Starmon and the Pickmons end up coming to Dondokomon's aid as Taiki tries to break up the fight when Lucemon shows up. Just then, Gargoylemon and a bunch of Unimon arrive as Lucemon arrives to take blame for Dondokomon. After Gargoylemon leaves once finished disciplining him, Lucemon explains about the Angel Police Force before taking Xros Heart on a tour of the Heaven Zone. But Dondokomon's accidental knocking of one of the sculptures brings the Angel Police back to arrest him, Taiki, and Shoutmon on the charge of vandalism. Moments later, Akari, Zenjirou, Ballistamon, Cutemon, and Lucemon visit the Angel Police department where they are told by a Piximon that Dondokomon is being interrogated by Gargoylemon. But Ballistamon ends up busting their friends and getting every member of the police force after them before the group are captured by the Angel Police captain and Heaven Zone's president GuardiAngemon.
The next day, Xros Heart are in cages in the Heaven Zone's arena where they are to be executed. Before the execution can commence, Lucemon speaks out and a Cupimon confesses to the destruction of the sculpture, taking Xros Heart's place in execution until the crowd speaks up. When GuardiAngemon retaliates in response to the public's act of defiance, Taiki ends up forming Shoutmon x4 to fight him. But when Shoutmon x4 ends up overwhelmed by GuardiAngemon, Beelzemon arrives and tells Taiki to combine him with Shoutmon. Taiki does so and forms Shoutmon X4B enabling him to match GuardiAngemon's speed. In the end, Shoutmon X4B spares GuardiAngemon at Taiki's request with Lucemon convincing GuardiAngemon to spare Cupimon's life. The crowd cheers this on as Lucemon gain their support in the upcoming presidental election with Shakkoumon watching from afar.
