Kiriha is tricked by Gravimon into believing that Taiki is the reason he could never achieve his goal to be strong as the boy is consumed by the darkness in his heart. Tension runs high as a fight breaks out among the Xros Heart United Army with Taiki being hesitant fight back against Kiriha. Although the core Digimon from both sides were injured badly, Kiriha refuses to stop fighting until Deckerdramon stops it and reasons with Kiriha to regain the love that has lost from his heart. The action failed, and caused Kiriha to have Deckerdramon mortally wound for insubordination. Taiki intervenes so Deckerdramon revealed the rest of Kiriha's past. Later, as Kiriha started to understand the source of his love, Gravimon appears to launch an attack from above with Deckerdramon shielding everyone with his own body. Kiriha soon realized that his power lays within the love and bond between him and his teammates. Though Deckerdramon dies due to the impact of Gravimon's attack, his final action gave Kiriha, Taiki and Nene the will to execute Great Xros, a brand new DigiXros with their main Digimon forming Shoutmon ×7.
