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.

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.
