Hi everyone, this is my first story. My friend Haru Shinkai gave me the idea of writing this story, so I hope that you like this chapter. I also suggest that you check her stories. This chapter will be based on both episode 9 and 10 of the anime.

Day One, Meeting

Haru and his friends were having a tournament with all of their Appmon to decide which Appmon was the best one. And this tournament only started, because, Gatchmon and Navimon had an argument about which one of them contributed more to DoGatchmon's form.

They were at the last event, that consisted of a battle between the main Appmon buddies, doing an applink with another Appmon, so in the end Gatchmon was paired with Roleplaymon, Dokamon with Navimon and Musimon with Perorimon.

When they were in the middle of the battle, a new and mysterious Appmon appeared, it called itself Hackmon. And with just one attack, he was able to defeat all the Appmon and undo their applinks.

Then he teared up the Cyber Arena and they all ended up in a destroyed AR Field.

Hackmon told them that they were too weak to defeat Leviathan. After hearing that Gatchmon tried to attack him, but he dodged the attack. They found him standing next to a boy wearing a black hoodie and saw that, that boy was holding an AppliDrive.

Before they could comfort the mysterious boy, he and Hackmon left.

"Who was that?" Astra asked confused.

"He had an AppliDrive." Eri commented with a shocked look in her face.

"Does Leviathan, have and AppliDriver on his side?" Gatchmon asked.

Could that boy really be on Leviathan's side? Haru thought, not liking the idea, that, that fact had the possibility of being true.

A few days, after the encounter with that boy, Haru and his friends were invited to the 7 Code Appmon meeting by Mailmon that is also one of the 7 Codes, where they thought they could befriend the remaining codes.

But in the end, it turned out be a trap, made by that mysterious boy.

"Who are you?" Haru asked.

"Who am I?" The boy asked. "Before that…change your clothes."

Everyone realized that they were still in their swimsuits and changed back into their normal clothes. Gatchmon then tried to search who that boy was, but his search gave error, because the appmon beside the boy, hacked Gatchmon's magnifying glass.

"I guess, I don't have anything to lose by telling you my name." The boy says "I'm Rei."

"Rei" Haru said.

"And I'm Hackmon." Hackmon said "And we will be taking all of your 7 Code Appmon."

After hearing that, they realized that the meeting was just a trap set for them. Then they decided to appfuse their Appmon into their Super grade forms.

Rei also made his buddy reach his Super grade form, but different form the other three, he made a Super Applirealise instead of an appfusion, which surprised everyone.

They all fought hard, but they were no match to Raidramon and lost. And with that Raidramon stole the 7 Code Appmon Chips from them.

"They only had two." Rei said. "At least it saves me some time."

"Rei!" Haru said. "Give us back Roleplaymon and Gomimon's Chips, please. We need to stop Leviathan, I don't want our peaceful lives destroyed."

Rei gave a cold stare to Haru for a long time.

"It's better if you don't attempt to get near Leviathan." He said."And if we meet again I will finished this once for all." Then he left.

After that, Haru and his friends returned to their world and started questioning what they should do.

But Haru wasn't paying attention, to what his friends were saying.

Is Rei-kun really in Leviathan's side? Isn't he also an AppliDriver, so why would he be on his side? Aren't we AppliDrivers supposed to fight against Leviathan?

All this questions kept coming up in Haru's head, but he couldn't find an answer to any of them.

Haru then looked up at the sky and started wondering why Rei would do this and if they would be able to find him and get back their 7 Code Appmon.
