Today is the day to bring their daughter to the office. Sid goes to his father's work while his sister goes to their mother's work.

Sid and his father are at the first metro station. Passengers board the metro.

Among the passages. Sid saw a boy with reddish brown hair in a yellow sweater and an Appmon that looked like a yellow cat.

"An Appmon !?"

"Where?" Offmon can't see it.

"There, the boy with the yellow sweater ..." Sid had lost sight of the boy in the yellow sweater. "Maybe my imagination. "

"Sid, come see." The Asian girl joins her father in the main car.

"What is it, Sid?" Offmon asks.

"It's nothing, I must have been dreaming ..."

"Sid, are you coming? "

"Yes Dad. "She gets on the train.

Stephen explains to his daughter that the train is controlled by Ressha's app. A program that allows trains to be run safely.

"With this app, can you do everything?"

"Right. We've even tested it before and the results have all been successful."

"Wow."

Sid and Offmon see the app's Appmon.

"An Appmon."

"An Appmon?"

"I mean, the app. I was wrong in my words. " Sid said.

Stephan starts the application, Resshamon begins to calculate the route of the stations.

"Another day of work with Mr. Chang. See what the journey will be today. " Resshamon helps work with Sid's father.

Stephan starts the application. At the same time in the train circuit AR Field.

Two figures appeared should Resshamon.

"Who are you? What are you doing here?"

"Our presence here you don't need to know, you'll eliminate its passengers. "

"What!? I will never do that. "

"Virusmon."

The Appmon virus releases a poisonous gas containing L-Virus. Resshamon is infected.

"At your command, master. "Resshamom changed the path of the train and increased speed.

The passengers who are supposed to disembark at the next station are stranded in the fast moving train.

"Dad, is it normal for the train to speed up? "

"Strange. I have been using the app for a long time and this is the first time this has happened. I hope it has not been infected with a computer virus."

Sid's father tries to slow down but Resshamon is in control and triples the speed.

Passengers missed several stations.

"It's definitely not normal. I'll have to stop the train manually. "

"Oh no. I won't let you stop me! "

Resshamon set the maximum speed. Sid and his father are thrown onto the wall.

"Sid, I think Resshamon is infected with a virus. "Offmon said.

"I think you are right. We have to go to AR Field to stop him. "The Asian girl whispers.

"Yes."

"Pa. I'll see if he doesn't have something for this kind of situation in the other toilet wagon. "

"Ok, Sid. "She goes to the washroom, uses her Driver App and enters the train's AR Field.

"Appmon chip, ready!"

Driver App: Apply! Offmon, Off Game.

"Now let's stop this train. "

They see Resshamon is out of control.

"Next station: Collision to DownTown station!"

Resshamon further increases the speed of the train, which is traveling extremely fast.

"Sid! With this speed, the toothed train risks colliding with the station and injuring many people! " Offmon said.

"We have to hurry to stop it. "

Sid evolves Offmon on Logomon. The two are in pursuit of the Appmon train but the enemy has set up Appmon Firewalls to block them.

"You do not pass!"

The Protecmon make a wall to prevent Sid and Logomom from being blocked by them.

"Scratch Bam !" The bipedal coyote eliminates the three in front of him.

But other Protecmon come to prevent them from advancing.

"Resshamon will soon be at the station."

"You do not pass!"

Their number increases again and again until they form a huge giant wall in front of them.

"They're wasting our time. Scratch Bam ! " Attack the enemy with its claws.

"Logomon is trying to make a way for you. "

"I'll try. Loga Blast! " The bipedal coyote creature tries to decrease their numbers but is unsuccessful.

? : Deu: Circle Tornado !

An electric tornado blows the Protecmon who are sweeping everything away.

"How are you?"

"Yes, thanks." Sid saw that it was the boy she had put on the train.

This is the time she sees his face and blushes.

"Hello..."

"Hello, I am Codex. I saw you were having trouble with the Protecmon. " He blushes too.

"Thank you so much. "

"Ahem! Sid, I have to remind you that he has a train that needs to be stopped. "Logomon reminds us of their mission.

The Asian girl finds her senses.

"Yes! The train! Resshamon. Where did he go? " Sid is looking for the Appmon train.

"Resshamon is over there. "Logimon pointed.

"Yes, we have to stop it."

"Go ahead! Me and Logimon will catch up with you. "

"Be careful. "Sid and the Appmon Off Log are chasing Resshamon.

A new opponent has appeared behind Codex. A character resembling Codex but with different colors.

"Here you are, dirty copy."

"You dare compare me to a vulgar copy? I am superior at all levels. Calcumon! "

"You will be subtracted in dust!"

The Calculator Appmon attacks Codex and Logimon.

On their side. Resshamon soon caused the train to collide with the station.

There would be two stations left.

"Ooh Chou! Next station, total destruction with many injured! "

Now there is only one station left before the collision. The Appmon coyote runs after the Appmon train and catches it.

"Scratch Bam !" Logimon claws the enemy.

"Hey!" Resshamon accelerates to escape Logimon.

"Logimon, get it!"

"Including. "The coyote creature runs faster and launches ranged attacks. "Loga Blast!"

A laser beam is fired at Resshamon who tries to dodge them.

"Loga Blast !" Its ray touches the rails. Resshamon loses control of his driving and slows down.

"Why am I slowing down? I want to go fast! Faster!"

Logimon gives him the fatal blows with Scratch Ban.

The Appmon is captured and purified from the L-Virus.

"We have succeeded! "

"Well done Sid." Codex joins them. And holds Sid's hand. The girl blushes.

In the real world. Stephen Chang then regained control of the train and managed to stop it.

"He's finally quitting. "The passengers get off the train. "Sid? Sid, where are you? Sid? "

Sid and Codex appear in the real world.

Sid is thrilled. Sid's father sees an unknown boy holding his daughter's hand.

"Ahem!"

"Dad?"

"I think I'm going to go away. "

Stéphan is happy to see that his daughter is correct.

In the AR Field. Cyber and Calcumon have taken a lot of damage.

"How ... I'm supposed to be stronger than him ..."

A message from Leviathan is displayed in front.

Message from Leviathan: Return to the Dark Web to heal yourself. After I have a new mission: Target Lincoln Loud and his group.

"... Ok. Lord Leviathan. "

They transfer to the dark part of the web to heal themselves.
