Fiction
On October 1, Haru is checking out books at Fujimizaka Middle School's library, unaware that he is under observation. He heads out and sees his friend, Yuujin Oozora, playing soccer while his crush, Ai Kashiki, watches. Distracted by Ai, Haru takes a soccer ball to the face. Yuujin then sees him, deciding to head home as well. The two of them discuss each other's main character qualities before parting ways. Haru is then notices that a vending machine is displaying his name, which then asks if he is a main character. As he wavers over his choice, the vending machine suddenly entrusts him with an Appli Drive. Haru takes the device home and plays with it, while reports his actions to Leviathan.

Deciding to search for more information, Haru attempts to use his smartphone only for to emerge from it. After Gatchmon explains the concept of Appmon, he declares Haru to be his Buddy, though Haru refuses. Gatchmon begins to fade, however, having exhausted his personal power in the Real World. Haru's attention is then drawn by his mother, whose messaging app is on the fritz. Gatchmon reveals that an virus-infected is the cause. Messemon proceeds to reveal embarrassing images to world, including Haru's bed-wetting photos. After Ai and her own embarrassment over a bad haircut photo and then Yuujin stepping up to the plate to comfort her, Haru flees in shame. They discover Messemon fleeing into an AR Field, and Haru and Gatchmon give chase. Messemon attacks the pair in there. Gatchmon calls on Haru to appliarise him, but Haru is too scared. Despite being in his weak chip form, Gatchmon defends Haru, telling him that he has confidence in him. Seeing Gatchmon's stubborn drive and pain, Haru eventually decides that he does want to be a main character, unlocks his Appli Driver, and appliarises him.

Now at full strength, Gatchmon attempts to scan Messemon for a weakness, but the relentless attacks prevent him. Haru aids him with a keyword, allowing Gatchmon to perform a search and realize Messemon's weakness: that words can only do damage if you let them. Gatchmon uses this idea to simply ignore Messemon's attacks, allowing him to get close enough to attack and purge Messemon of the virus, obtaining Messemon's Appmon Chip in the process. The partnership cemented, the pair exit the AR Field. Haru has another conversation with Yuujin, who notes Haru's changed outlook, while Haru's mysterious watcher upgrades him from a main character candidate to main character status.

On October 8, Haru heads to Kashinoki Books, meeting Yuujin on the way. There, they listen to Takeru "Watson" Wato's woes due to his navigation app going on the fritz, which prompts Ai's father to realize that Ai has not returned from her errand. Haru immediately proposes a search for her, which causes Yuujin to comment on his proactiveness. While searching, Gatchmon reveals to Haru his investigation into Leviathan and the L-Virus that has been infecting Appmon. They then come across the virus-infected, who has been the problems with the navigation apps. While they give chase, Yuujin calls Haru to tell him that he found Ai and escorted her home; this frees Haru to enter an AR Field against Navimon. Navimon proves a difficult foe, but after searching for a way to confound Navimon's homing powers, Haru applink Gatchmon with Messemon. Gatchmon then manages to defeat and purify Navimon, leading Haru to obtain his Appmon Chip. Immediately afterward, they are attacked by Cameramon, who blinds Gatchmon. Haru desperately thinks of a way out and then attempts to applink Gatchmon with Navimon. He accidentally performs an App Fusion instead, calling. DoGatchmon forces Cameramon to flee with one attack.

On October 15, Haru discusses DoGatchmon with Gatchmon and Navimon, learning that, while most Appmon can Applink with each other, certain pairs of Appmon instead perform a fusion, combining and increasing in grade. Gatchmon mentions that it will take a while for DoGatchmon to be able to be appliarised. Yuujin calls for him afterward, and the two head to Kashinoki Books to hang out, where they find Watson and his friends discussing Fantasy Saga. Watson, however, discovers that his high level character has been reverted to base while missing his legendary equipment, a phenomenon which soon spreads to the others. Haru observes exiting from his smartphone, so he and Gatchmon give chase, ending up back at school. An AR Field exists, which has turned the school into a recreation of the Amusing! Exciting Dungeon video game. Haru finds great excitement in the subsequent dungeon crawl, though Gatchmon is annoyed. At the end, they find a despondent Ropuremon who is angry that they used a walkthrough to make it to the end. After Gatchmon accidentally pushes Ropuremon's berserk button, he grows into a huge size befitting a final boss. Haru attempts to appfuse DoGatchmon once more, but the fusion fails, forming the ineffectual instead; Haru attributes this to Gatchmon's and Navimon's discord. Right before Ropuremon can strike down Gatchmon, Haru tells Ropuremon that he honestly enjoyed his adventure. Seeing Haru's sincerity allows Ropuremon to purify himself of the L-Virus, and he surrenders his Appmon Chip while revealing himself to be a 7code Appmon. Haru obtains the Appmon 7code PAD in the process. Gatchmon believes that gathering all the 7code Appmon will unlock a power that will allow them to face Leviathan, so they make it their goal to obtain all seven.
