The story begins with a seventh-grade boy named Taiki Kudō dreaming of commanding a Digimon army. The next day, Taiki spots a red creature flickering in static and hears a mysterious voice which presents him with a Xros Loader, into which the creature is absorbed. He and his friends, Akari Hinomoto and Zenjirō Tsurugi, are then sucked into a portal to the Digital World, where they are attacked by MadLeomon and his troops. The group is rescued by Ballistamon, Starmon, the Pickmon, and the mysterious red creature: Shoutmon. After Taiki and his Digimon companions fight back against MadLeomon and his troops, MadLeomon absorbs some Chikurimon, Troopmon, and Mammothmon to become Armed MadLeomon. Taiki uses his Xros Loader to allow Shoutmon and Ballistamon to DigiXros into a more powerful form. After injuring Armed MadLeomon, Shoutmon then uses the DigiXrossed Starmon and Pickmon, in the form of the Star Sword, to strike down Armed MadLeomon with a finishing blow. A portal appears recalling MadLeomon and his minions. Later, several Digimon are seen conversing about their evil plans after seeing the fight. As the episode ends, a boy and a girl, each with their own Digimon companions, watch Taiki's group from afar.

The kids go with Shoutmon to his home, Village of Smiles, where they are thrown a party. Soon after Taiki decides to try to leave the Digital World and return home since he accidentally dragged Akari and Zenjirou with him, causing Shoutmon to become upset. The humans and digimon go their separate ways but MadLeomon attacks the kids once more, combining with Orochimon. Shoutmon comes to their rescue and with the help of Taiki to DigiXros, becomes Shoutmon X2 and defeats MadLeomon, causing the evil digimon to retreat. Nene is seen watching Kiriha and Taiki individually, evaluating their fighting skills.

The Village of Smiles is suffering from the threat of the event known as "Day of Rising Ground." The human boy known as Kiriha appears and informs Taiki and the others about what is happening, offering his help but only if Taiki joins his side and serves under him. He mentions something about the "Code Crown" as well. Refused, Kiriha uses DigiXros on MailBirdramon and a Golemon to fight Shoutmon and his friends. However MadLeomon's forces decide to attack the village as well...

The mysterious and beautiful girl known as Nene explains to Taiki and the others about the Code Crown. It is revealed that what they have is but a fragment of a larger piece and that there is a fragment for every Zone. Using the fragment's power to do a Zone Transfer, Taiki's Xros Heart army ends up in the Island Zone, surrounded by a vast ocean. However they quickly find out that this is not an island paradise as the Bagura Army's influence is in this zone as well. The struggle to find the zone's Code Crown begins!

Captured by Neptunemon, Archelomon is forced to give up the whereabouts of the Code Crown. In order to protect the Code Crown, Taiki and the others head into the stomach of a gigantic Digimon, Whamon. There, the group, as well as the Bagura Army, wage battle inside Whamon. Later, they find DigiMemories of legendary digimon under Whamon, and using them, they summoned legendary digimon Leviamon.

Teams Xros Heart and Blue Flare must protect KingWhamon and the Island Zone's Code Crown from Neptunemon's Seadramon army. Taiki realizes that a DigiMemory can only be used once and summons the memory of MarineAngemon to fight off the Seadramon army. They then take on Neptunmon himself....

Team Xros Heart arrives in the Magma Zone where they decide to relax a bit in the hot springs. Their time for relaxation is cut short when SkullMeramon and some Meramon of Bagura Army shows up. Cutemon and Dorulumon comes to their rescue once more and Cutemon reveals that he is looking for his parents. Also it seems that BlueMeramon in the Bagura Army knows Dorulumon...

To prevent AncientVolcamon from destroying the cave and killing the prisoners, Taiki issues a surrender from Team Xros Heart. He then hands over a fake version of his Xros Loader and the gang is lead away to a cell where they hope to find Cutemon's parents. There they plan an escape unknowing that Tactimon has arrived to the Magma Zone, with an unexpected revelation.

Tactimon attacks Team Xros Heart and captures Dorulumon and Taiki, ordering their execution. Meanwhile Nene informs Kiriha of Taiki's capture and he comes to fight Tactimon. While Tactimon is distracted by Mailbirdramon and Kiriha, BlueMeramon helps Taiki and Dorulumon to escape along with the rest of Xros Heart. The group then learns more about Dorulumon's involvement with the Bagura Army while they look for Taiki's Xros Loader.

Arriving in the Lake Zone, Team Xros Heart quickly discovers that the Bagura Army is present thanks to IceDevimon's frozen victims. After rescuing a drowning Knightmon, Taiki and the others are introduced to the ruler of the castle of the Lake Zone: Persiamon. Meanwhile IceDevimon and his troops attack but when they fail and retreat, the general Lilithmon appears to take over. She then reveals the plan to thaw out a frozen powerful and dangerous digimon. Not only that but Taiki's rival Kiriha is at the castle as well!

Overdoing it during battle, Taiki passes out and Persiamon takes over to care for him. However Akari becomes sad and jealous since that is usually her job. Unfortunately Lilithmon seizes the opportunity to turn Akari's emotions against her and control her, forcing Akari to find the fragment of Code Crown and bring it to her. Meanwhile as Taiki recovers, Lilithmon also unleashes the powerful digimon Daipenmon who nearly wipes out Taiki's forces that Zenjirou is leading. At the very end Nene appears before Kiriha, saying she has decided to team up with him, revealing that she wields a black Xros Loader.

Now in the Sand Zone, Team Xros Heart is suffering from the blazing sun and quickly falls into a sand trap laid by Scorpiomon of the Bagura Army! Then falling deep underground, the team is cornered by a bunch of Scorpiomon just before Revolmon appears and saves them! Only it seems that as a favor for saving them, Team Xros Heart must help Revolmon with his treasure hunt! But it's not going to be an easy task as what's a treasure hunt without some booby traps and battles!? Not to mention the Bagura general Blastmon is currently present in the zone!

The battle between Blastmon and Nene and Kiriha's forces continue. Meanwhile as Team Xros Heart investigates the commotion, they are attacked by Baalmon who accidentally reveals an old Digimon goddess statue that has been buried. While fighting, Blastmon causes the ground to collapse, making Taiki and the statue to take a tumble deep underground, separating the kindhearted general from his friends. Baalmon then appears before Taiki and says Taiki has been blessed by the goddess and is now her warrior. In response, Baalmon helps lead Taiki from the underground while enlightening him about the past of the Sand Zone and the goddess warriors. Eventually Taiki learns more about Baalmon himself and his tragic past...

After Baalmon is fatally wounded by Lilithmon, Taiki is instructed by Pharaohmon to use the Sand Zone's Code Crown which rises a pyramid that carries Team Xros Heart and Baalmon away from Lilithmon and her SkullScorpiomon army. Taiki uses his DigiXros to summon the statue of the Digimon Goddess to begin healing Baalmon's wounds. Meanwhile Lilithmon's forces try to break into the pyramid and Team Xros Heart all band together to fight while being unable to Digi Xros. Will they be able to fight in their reduced state and can Taiki save Baalmon!?

Meanwhile, Xros Heart arrives at the Zone and amaze by the surrounding. Later, Taiki falls off a cliff but is saved by Shakkoumon. Dondokomon drums disrupting a Pucchiemon orchestra and gets in trouble with a police Piximon. Taiki tries to stop the argument caused by Dondokomon as Lucemon shows up to clean the mess. After the argument is off, Lucemon tells Taiki and the that Gargoylemon is a member of the Heaven police. Lucemon then takes them on a balloon tour, but Dondokomon knocks down a sculpture. Gargoylemon arrives and arrests Dondokomon, Taiki, and Shoutmon. Moments later, Taiki teammates and Lucemon visit the police department where they are told that Dondokomon is being interrogated. Ballistamon ends up busting Taiki, Shoutmon, and Dondokomon out which alerts the rest of the force.

Before Lucemon takes off, he is grabbed by Ballistamon and then attacked by Dorulumon only for him, Ballistamon, Starmon, and the Pickmons to be knocked away. When he starts to unleash an attack on Taiki and Shoutmon, it ends up blocked by Shoutmon as Lucemon ends up attacked by Beelzebumon. Taiki then forms Shoutmon ×4B to fight Lucemon with Shakkoumon giving support before defeating Lucemon so Taiki can claim the Heaven Zone's Code Crown. Shakkoumon teleports Xros Heart to the floating building and find Nene harvesting the dark energy ball's energy for DarkKnightmon. Just then, having survived, Lucemon appears and grabs Nene while draining the dark energy. However, this results with Lucemon being overwhelmed by the dark energy as it engulfs both him and Nene before Xros Heart and Sparrowmon's eyes.

As the dark energy ball engulfs Lucemon Chaos Mode and Nene, Sparrowmon tries to grab Nene but fails as the energy digivolves Lucemon into his Shadowlord Mode with the girl trapped in the Gehanna sphere.

But neither the Xros Heart Digimon or Sparrowmon could stop Lucemon as he siphons all the dark energy from the Heaven Zone's darkness-infected citizens, growing bigger as a result while a Monitamon informs DarkKnightmon on the current situation. While Xros Heart regroups to figure out how to defeat Lucemon, Nene reflects on the time when she was with Sparrowmon. Sparrowmon wakes up in Xros Heart's care as Lucemon starts to absorb the Heaven Zone as Shoutmon ×4, Beelzebumon, and Shakkoumon are unable to stop him.

With Stingmon and Lilamon defeated, Nene demands Kiriha to have MetalGreymon torture them for information on the legendary Digimon, but Kiriha refuses insisting that he only lives to fight those who are the strongest. Upon hearing their conversation, DarkKnightmon emerges from Nene's Xros Loader and ends up fighting MetalGreymon until Taiki arrives with Shoutmon ×4B to stop the fight.
