Prologue Chapter: Star Angel and The Solitary Star

Fifty-seven years ago...

Solar Collecting Space Station "Amaterasu"

Amaterasu Net Area 03

Sounds of explosions and clashes of weapons resound through the entire area, as viruses are deleted left and right. A lone Navi continues its attack as it turns around to fire to the surrounding viruses, aiming for vital spots with amazing accuracy. Soon, only silence prevailed as the viruses in the area have been completely deleted.

"Laser, report status!!" a voice called through the Navi's communications as he brings up a screen to his operator. The Navi known as Laser stands at a height of 5'5" and is garbed in a blue-and-white color scheme of a light frame armor that is highlighted by an occasional red on certain parts and a green prism as a chest plate. A visor covers his azure eyes as shoulder-length golden hair give him the look of a celestial being.

"Amaterasu Net Area 03 clear!! Operator: Kojuro..." Laser replied promptly to his operator as he disarms the buster on his arm, the Shining Buster, "It is best if we search for the lock and decode it to gain access to central control.

"Wakarimasu (trans. "Understood"), Laser... log out!!" Kojuro declared as Laser turns into a beam of data and promptly returned to his PET. Seitamashii Kojuro, now 38 years old, is a special member of ONBA's Netbattlers. He belongs to a family that are known for their ability to quickly comprehend concepts in technology and develop means of improving such concepts into applications. Standing just about as tall as his Navi, Kojuro's hair has changed to the crew cut instead of the well-combed short hair he has when he was still a teenager. He is wearing a space suit at the moment as he has just came through the space station's air lock half an hour ago.

Moving towards the door, Kojuro pressed on the switch nearby to finally have the door opened. Nodding in satisfaction, he then enters the door to lead into a large chamber filled with numerous computers and servers: Amaterasu's main control room. The red emergency light has been blinking ever since Kojuro came into the space station, signifying a breach into the security by some unauthorized individual... or some form of virus.

Without emotion or signs of being awed by the presence of such a large system, Kojuro quickly headed for the central server of the system. Taking out his PET, Kojuro pulls out the cable and attaches it to the terminal visible on the server's side. Laser immediately appears into the server's entry area and moved in. He then stopped moving forward as he encounters a red wall that resemble some sort of shield.

"Kojuro, there is a firewall here..." Laser said as he sends visual and technical data to his operator, "Either we are supposed to possess the Priority 1 access code, or we have to decode the password by ourselves."

"We have no time for finding an access code, Laser," Kojuro said as he brings out a handheld device and slots it into his PET, "Initializing decoder sequence!"

"Initializing decoder sequence.... Estimated time of completion will be thirty minutes, Kojuro..." Laser replied as he begins to do the decoding.

"Still too long, we won't make it in time..." Kojuro said as he looks around for something that could help speed up the process.

Just then, two more Navis appear beside Laser. One is a female Navi that looked like a senshi, while the other Navi resembles a dragoon. Both Navis stood beside Laser as they both initialize and execute the decoder sequence, assisting Laser in dealing with the firewall.

"Crystal? Dragooner? What are you doing here!?" Kojuro said as he sees what is going on in the server, "Then that means..."

"That's quite rude of you, Kojuro-san..." a man's voice said as his face appeared in a window on the screen of Kojuro's PET, "Don't you know that help should always be welcomed?"

"That's right, Kojuro-san..." a woman's voice called as her face also showed up in a new window on the PET's monitor, "Ken-san and I figured that you may need help on figuring out how to decode the firewall's protection..."

"Kojuro!! We have decoded the firewall's password!" Laser called out as the red wall finally vanished, "Thank you for your support, Crystal, Dragooner!"

"No problem, Laser-san!" Crystal replied as she gave him a wink, "That's why we came along!"

"It is our pleasure to be of assistance, Laser..." Dragooner replied with a nod, "Now, make haste to reach the server, our time is limited..."

"See you later, Kojuro-san..." Ken said as he gave Kojuro a salute, "Yume and I will be waiting for you in the shuttle just circling around the space station..."

"Sou desu..." Yume nodded in reply, "Be sure to come back to us..."

With that, the two Navis logged out, leaving Laser to turn around and rush into the deeper recesses of Amaterasu's server. After a long dash to through a quiet path, Laser finally steps into the main net area of the server. Before him is the server's inactive program... as well as something else.

"A multi-bug organism...?" Kojuro frowned as he recognizes the features that are similar to the first multi-bug organism that existed. The only difference is that this multi-bug organism resembled Laser's form. Turning to face Laser, the bug clone grew bat-like wings on its back and took to the air while it forms a black sword on its hand.

"Laser, initialize and execute battle mode!!" Kojuro declared to his Navi as he loads in a Sword chip into his PET's slot.

"Battle mode execution!!" Laser replied as he glows and forms angelic wings on his back. Following towards the bug clone, he unleashes his sword for combat. The two clash in a mid-air combat as they exchange blows and parries as if in an elaborate sword dance, only managing to deal minor nicks and slices at each other as they fly around. The sword fight ends with both Laser and his clone pushing each other away, as Laser notices some form of timer on the clone's chest.

"One minute remaining before the Amaterasu fires its solar charge earthwards, Laser!!" Kojuro said as he looks to his watch and back to his PET, "Get ready-- FULL SYNCHRO!!!"

Kojuro's body glowed an unnatural light as Laser's systems start to improve its efficiency by up to 150%. The clone noticed this, and begins bringing up an aura to protect itself while bringing out a larger sword to deal with Laser. On the other hand, Laser's body glowed into a golden color as his powers reach beyond its normal capacity.

"Ikuze Laser!!!" Kojuro declares as he inserts his three best sword chips into the PET, "Advance attack: Life Sword 3!!!"

Laser extends his sword arm out as a grand and elaborate sword appears and extends from his arm. Again he engages with the bug clone in a deadly battle of swords. However, this time he fights with near god-like speeds. Damage is still unavoidable as the blows come harder, but this time, even Kojuro is getting affected with each blow the clone manages to land on Laser.

"Twenty seconds left..." Kojuro murmured as he wipes the blood that is flowing down on his left cheek, "Laser, give it everything you've got!!"

16, 15, 14...

"Affirmative!!" Laser replied as he smashed with all his might on the clone's blade with his sword, smashing both weapons to pieces. Bringing his other arm up to bear, he shows that he has been holding a charged attack all the while.

8, 7, 6...

"Stellar Shine Burst!!!" both Navi and operator yelled at the same time as Laser punches his opponent at the chest.

4, 3, 2...

A bright and stunning flash followed inside the server's net area, flooding the place with a blinding light. Even in the control room, the blinding flash has surrounded the place.

'Sayonara... minna-tachi... Soshite, Miyuu-san...' Kojuro said as the flash of light surrounded him as well. Memories of his memorable moments with friends flash by his eyes as they begin to close and he finally smiles as he falls backwards.

0...

What followed next is silence. Amaterasu's solar releaser remained silent after the countdown has passed. Even inside the station, everything is silent...

Hours later.....

Inside a Hospital at Seikuu Province...

"It has been hours since the doctors are checking up on what's wrong with Kojuro..." Ken said as he glances at the digital clock that is located up the wall of the hallway, "I don't like the way this is turning out..."

Standing about 5'9" in height, Seitamashii Hoshi Ken has grown to have the features of a gentleman. A charming face, well toned body, and clothes to match his classiness. The only thing that is out of place is the left eye that has not changed since his childhood days, having a yellow-hued pupil that resembled that of a dragon's eye.

"We're all worried about him..." Yume said as she rests her arms on the level surface of her hoverchair, "Yet... I recall something that he said before... something like: 'To shine brighter than any other star, even if for a moment'... Do you think there is any relation?"

Only at 5'6", Seitamashii Tsuki Yume has grown to become a beautiful woman. Succumbing to a disease that affected her nervous system at the lower body, she has resorted to using a hoverchair provided by her superiors. Despite her disability, Yume still continues to offer help as a researcher for Navi development... and often times, as a netbattler.

"Soreja, they better hurry up!" Crystal piped up from Yume's PET, "Laser-kun's back-up contained nothing more but the basic framework of the experimental Navi he was based from!!! We can't get anything to bring him back from that!"

"It would seem to me that Sir Kojuro knows Laser's programming code by memory and heart..." Dragooner mentioned from Ken's PET as Ken took it out, "This is truly quite a dilemma..."

The light of the operating room finally dims as the doors open. One of the doctors stepped out from the room and looked to the two Seitamashiis.

"Well, good doctor? Will he be alright?" Ken asked as politely as possible despite the anxiety that is building up within him.

Taking off the surgical mask, the doctor's face is grim and solemn he gives the two an explanation of Kojuro's condition.

"Sonna... masaka..." Yume remarked as she brought her hand up to cover her mouth. Ken could only look away as tries to hold back the tension.

A week later...

Hall of Celestials in Hokuto City, capital of Seikuu...

Rain has been pouring for days since the ceremony has ended, as if the heavens are crying for the loss of an individual. The Hall of Celestials has always been the final resting-place for the departed of the Seitamashii. Somewhere within the massive hallway, the body of Seitamashii Kojuro lies in stasis. Beside him is a holographic image of his Navi, Laser.exe, standing in solemn silence. Kojuro's hair has turned white as he lies inside the pod, his face showing a sign of content.

"They say that Kojuro pushed his synchronization capabilities way past its limits..." Ken said as he looks at the monument, "It somehow caused his essence to part from his body and join Laser's body during that moment."

"Amaterasu's technicians have searched high and low throughout its server's net area..." Yume then said, "They couldn't find any trace of Laser... or Kojuro anywhere..."

And so ends the life of Seitamashii Kojuro at age 38. Called the Solitary Star while Laser is known as the Star Angel, the two are known to be inseparable and steadfast. Like his call name, Kojuro never had shown much emotion to anyone... even to those who consider him as a friend. Known to stand up even against fearsome odds, people could only wait for the time when he will ever awaken from his slumber.
