Faris NyanNyan, Mayuri Shiina and Luka Urushibara, because of Mayuri's influence, are all fans of RaiNet Kakeru, though while Luka is rather interested in its story and Mayuri is interested in both the story and the Upas, Faris is more interested in the card game.

Access No. 1: The rumoured guy is no good?! Mystery Transfer Student
A net café in New York City. Someone types an email.

"In an hour, start the cyber attack against the Department of Defense..."

Kakeru Yumehara is a fifth grader who just recently transferred into Kaigyou Elementary. Although flawless in academics and sports, he doesn't particularly stand out.

His classmates, Kirari and Tamaru, are members of the school's small computer club, and try to get Kakeru to join with the reasoning that they need anybody to increase their numbers.

But Kakeru isn't interested.

Kirari: "He's probably not good with computers. It can't be helped."

Then one day, during computer class. Tamaru shows off his touch-typing skills to Kakeru. While rebuking Tamaru for that, Kirari displays her abundant knowledge of computers and the internet.

Tamaru: "Hey, Kirari, look at the transfer student. He's only using one finger to type."

Kirari: "Come on, stop that, Tamaru. He's just a transfer student, so he can't help it, can he?"

Everyone in the class looks down on Kakeru's lack of ability when they see him slowly press keys one by one, as if confirming each indivudal keystroke.

It is at that moment that a low whirring sound emerges from Kakeru's bag. As everyone looks on in amazement, he reaches in and pulls out a subnotebook PC that would make any kid jealous. Moreover, it has a unique design.

Tamaru: "This guy can't be for real! A subnotebook even though he types one-fingered?!"

Kirari: "That's not it, Tamaru. Look, that subnotebook doesn't have a display!"

Tamaru: "Ki-Kirari! I've never seen anything like that! It's making a screen!"

The "Upa" inside Kakeru's notebook delivers an emergency mail from Nagaya-san. Written in the mail is the surprising news that the Department of Defense has been hacked.

Upon confirming the contents of the mail, Kakeru's eye colour changes and his movements accelerate to a surprising rate.

The entire class stares in disbelief as he removes the screen from the special subnotebook and connects the keyboard to a school computer.

As an emergency countermeasure, he uses the school computer to begin persuit of the cracker. Kirari and Tamaru are astonished when Kakeru starts operating the keyboard with violent force.

Kakeru pursues the traces of the cracker who hides his identity by using servers throughout the world. Easily exterminating obstacles such as trap viruses, he draws close to his opponent.

The net café in New York City. A window opens up on the monitor. Kakeru finally corners the opponent. Faster than cyber police units throughout the world and the CIA, Kakeru reaches the culprit's computer and accosts him through chat.

The culprit calls himself "J". J releases viruses. They are powerful things, which have the ability to force other people's computers to freeze.

But Kakeru defends himself by shooting a precise vaccine, slowly approaching the culprit's whereabouts. The location is found to be somewhere around New York. In just a few moments, he'll have the exact adress...

J is surprised by Kakeru's ability. "I never thought I'd have to use this..." he says as he takes out a strangely shaped CD-ROM. Kakeru is unable to defend against the viruses unleashed from the CD-ROM. Furthermore, all of the computers in the classroom are destroyed by that mystery programme.

The battle has ended in Kakeru's complete defeat. The computer room teacher's face reddens with rage. At that time, the school dismissal bell rings. While feeling regret, Kakeru rollerblades to his meeting with Nagaya-san.

Kirari and Tamaru, wanting to know what sort of person Kakeru is, chase after him. Nagaya-san tells him that the computer virus J used is the very dangerous Monster Programme "Vaios".

The mystery Monster Programme made for an unknown purpose.

Their destructive force is said to be thousands of times stronger than normal viruses. There are nine types of the unreproducible Monster Programmes. It is said that he who collects all of them can control the entire internet world.

Simply put, this Monster Programme is legendary on the internet. And a hacker has appeared who can use it. This is a global state of emergency.

"Whar should we do?!", Kakeru cries.

In reply, Nagaya-san takes out a gaudy-looking input card.

"We're not just going to stand here and watch. We're just about finished with developing a new RaiNet Card."

What is this RaiNet Card? And what is Kakeru's true identity?

Meanwhile, in New York City... The net café opens and out comes a pretty boy. "Kakeru, huh... What an interesting guy." While putting away a strangely shaped CD-ROM, he laughs like he's enjoying himself.

That boy is the grade-school hacker who shook the world in the past. "J"...
