Somewhere in the Digital World, Kiriha and MailBirdramon knock an Okuwamon to the ground when Nene appears. When Okuwamon rises, Mailbirdramon destroys him. Meanwhile, Neptunemon tries to get Team Xros Heart to surrender the Island Zone Code Crown and ends up threatening to harm Archelomon. Before Taiki can give up the Island Zone Code Crown, Kiriha arrives on MailBirdramon as he takes out some of the Seadramon. Taiki then uses another DigiMemory which summons a bunch of MarineAngemon that use their Kahuna Waves on them. With the Seadramon distracted, Team Xros Heart uses a bunch of Syakomon to get to the Mantaraymon that Neptunemon is on. Taiki forms Shoutmon x2 and then the Star Sword which Zenjirou uses to free Archelomon. Neptunemon then knocks Taiki, Shoutmon x2, Zenjirou, and Archelomon into the water and has the Seadramon freeze the water trapping them. Just then, Dorulumon arrives and attacks Neptunemon before freeing the others. Taiki then merges Shoutmon, Ballistamon, and Dorulumon into Shoutmon x3 before giving the formation the Star Sword, creating Shoutmon x4. Shoutmon x4 ends up fighting against Neptunemon's Vortex Penetrator, managing to trick Neptunemon into being destroyed by his own attack. As the ice starts to break, KingWhamon secures those on him and jumps high enough to evade the breaking ice. As Team Xros Heart celebrates their victory, Kiriha and MailBirdramon leave. Meanwhile, Tactimon gets word of Neptunemon's destruction. Shoutmon convinces Taiki to let them bring ChibiKamemon with them as Dorulumon takes his leave.
Monitamon: "Cutemon. His techniques include...er...uhm...Getting others to fall hopelessly in love with that cute face, I guess. Ah, love~" Shoutmon: "You just improvised that explanation, didn't you!"
