Prologue
It was the year 2044, a guy named Natsuki Yakushi moved to Tokyo from Kyoto. At birth He was given a Neuro Linker, just like everyone else. His father had gotten a job there and decided that they would move.
Natsuki met a girl named Kuroyukihime who he quickly became close to. Eventually they became close enough that they started dating. They were together for a couple months, and they'd spend every day together.
Then came the day Kuroyukihime was introduced to a game called Brain Burst. After, she started to become more and more distant from Natsuki. Everyday he tried to talk to her, but her mind was on nothing but Brain Burst; she couldn't talk or think about anything else. Natsuki than didn't understand what her obsession was with Brain Burst. She told him that it was more than a game. Natsuki just didn't understand.
"Kuroyukihime why are ya so obsessed with that game? Is it really that important?" Natsuki asked. Kuroyukihime wasn't paying attention, then she looked over to him.
"Hm? Did you say something?" She asked. Natsuki was a bit disappointed that she was paying so little attention to him. He started to believe she cared more about that game than him.
"Why do ya care so much about that stupid game?" Natsuki asked. She looked down, and paused for a moment.
"It's not just a game, I gave up my reality for it, and I've been tasked with a great responsibly." She responded. Natsuki still didn't understand. What was so great about this game? Why did she care so much?
The next day, Kuroyukihime thought about what Natsuki had asked. She thought that if she introduced him to the game, he'd understand. She went over to his apartment to see if he'd want to be her protégé in Brain Burst.
"I like games, but I think I'm gonna pass on this one. I have no interest in a game that makes my girlfriend distance herself from me, and I don't think playin the game myself will change anythin" Natsuki told her. Kuroyukihime was a bit upset, and decided to just go home.
The next day at school, Natsuki tried to talk to Kuruyukihime. He wanted to apologize for being so rude the other day. When he found her, he was just about to apologize, but she interrupted him.
"Natsuki, I'm sorry. I think we should break up." She said, looking away. Natsuki was confused.
"Why would ya want to break up? I mean, I know I may have sounded a bit rude yesterday, but I want to make it up to ya! We don't have to-"Natsuki stopped, she interrupted him again.
"Look, it's not about that. I just don't have time for a boyfriend right now, I'm sorry." Natsuki didn't understand. Was this game just that important to her? Did she really care about Brain Burst that much more than him?
The next day, Natsuki met another girl. A girl named Yukiko Kageyama. They became fast friends, and Natsuki was happy around her, almost as much as he was when he was around Kuroyukihime.
He soon learned that this girl was also into Brain Burst. At first Natsuki had no interest whatsoever, but then he became curious. He decided he'd give the game a try.
"Natsuki, if you're sure you want to it, then be sure that you are. Once you download this game, your entire reality will be destroyed." Yukiko warned.
"Hmph, it's not like my reality is very important to me anyway. All I want is to escape this terrible reality." Natsuki thought to himself. Yukiko sent the Brain Burst file to Natsuki's Neuro Linker and he downloaded it.
"Now, I want you to say Burst Link" She requested. Natsuki wasn't too sure, but he did.
"Alright, here goes nothing, Burst Link!" Natsuki called out. Suddenly, time appeared to slow down, and he found himself wearing different clothes. He was wearing a black cloak with a sword attached to his belt. He realized this was his school avatar.
"Wait, when did I connect to the school network?" Natsuki asked himself. He looked over to Yukiko, who was using her school avatar. She had silvery white hair with a blue and purple colored flower in her hair. She also had on a White Yukata covered with a blue and purple flower design. "Hey, what's goin on, why are we usin our school avatars?!" He asked, confused.
Natsukicould see himself, but he was still confused. Yukiko looked over at him, and grinned.
"With Brain Burst, our minds are able to think a thousand times faster than normal. Time appears much slower, as if nothing isn't even moving." She explained. Natsuki didn't understand at first, but as she explained how the Bust Link works, he understood.
The next day, he passed Kuroyukihime in the hall, but he didn't think anything about it. He didn't even look at her, but she looked back at him. He went to class, where he met up with Yukiko. They had made plans to meet up at a nearby coffee shop after school.
Later, after school ended, Natsuki connected his Neuro Linker to the global link. Suddenly, time began to stop, and Nathan knew exactly what it was. He knew it was Brain Burst activating, but he didn't turn it on.
Natsuki found himself downtown, and he wasn't in his school avatar. He had a mechanical-like body. He had two green eyes and his body was colored black with purple arms, his head resembled that of a snake. He had no idea what was happening.
"Where am I? What's going on?" He asked himself. He saw a bunch of people on a bridge watching him, and in front of him, he saw a guy with a red colored body and two lasers on his shoulders. He was as big as a cannon and a big green head. Natsuki looked up and saw what looked like health bars. One said Ebony Snake and the other one said Crimson Tank.
"Well well, if it isn't a newbie. This ought to be fun." Crimson Tank said confidently. Natsuki was scared; he didn't know what was going on.
"Well, if you're so confused, there's about thirty seconds till the duel starts so I'll be brief. This is a game ya know, so you've been challenged to a duel via the global network." Said a tall green girl.
"Yeah, didn't your master tell ya never to connect to the global network?" Asked a short red girl. Natsuki realized he wasn't told that.
"Guess Yukiko forgot to mention that." Natsuki said to himself. The duel started and the red fighter just stood there.
"Well if this is a duel, aren't we supposed to fight? Why are ya just standing there?" Natsuki asked.
"Charge complete, all systems FIRE!" Tank called out. He shot two giant beams out of his cannons.
"Oh shit!" Natsuki quickly ducked and the beams destroyed a building behind him. "Oh man, is this really a game? That blast coulda killed me!" Natsuki cried.
"This time you're not getting away! Prepare to be annihilated Ebony Snake!" Tank exclaimed. Tank's arms shot out and grabbed Snake.
"H-hey! I can't move!" Snake called out, trying to escape Tank's grip. Tank pulled himself closer, cannons aimed at Snake.
"Charge complete, all systems FIRE!" Tank called out. Two giant beams shot out and blasted Snake. His health bar fell to about half.
"Damn, that really hurt!" Snake cried. He charged at Tank and tried to punch him, but it didn't do much. Tank then swung his arm and Snake went flying. Then more of his health bar went down.
"You don't stand a chance against me kid, just face it." Tank said confidently. Nathan charged at him once more, and started to rapidly punch at Tank's armor. He was dealing very little damage.
"This is just sad." Tank sighed. He pointed his cannons at Snake and said "Time I taught you a lesson you won't forget noob! Charging, Ten Percent! Thirty Percent! Sixty Percent! Ninety Percent!" Snake kept punching until Tank was almost to half health.
"I'm not going to give up! Why won't this damn armor break?" Natsuki shouted. The cannons began charging even further.
"One hundred percent! Fully Charged! Ready, FIRE!" Tank called out, and his cannons took aim and shot Snake directly and wiped out the last of his health. Natsuki returned to the real world and message popped up saying that he lost. He saw a section on the screen that said Burst Points: 30 20. He wasn't too sure what Burst Points were, but he disconnected from the global network and headed to the coffee shop to talk to Yukiko.
"What? Oh my God, I'm so sorry. I forgot to tell you. When you connect to the global network, people all over can challenge you to duels." Yukiko apologized. "Well, it seems you lost your first duel, well that is expected. Just make sure your Burst Points don't reach zero." She warned.
"What happens with they reach zero?" Natsuki asked. Yukiko looked away, and then looked back at Natsuki.
"When your Burst Points reach zero, Brain Burst automatically uninstalls itself and wipes your memory of the accelerated world forever" She explained. After that, Nathan became more careful with his Burst Points. He learned that leveling up right away isn't a good idea, because it costs a lot of Burst Points to level up. Within the next year, Nathan had leveled up to level 4. Once he was this high in level, Yukiko introduced him to her master, the Purple King.
Natsuki and Yukiko had been sent on multiple missions together. They expanded territories for the Purple Legion. Natsuki had gained many items and abilities that he used to become one of the Purple King's most valuable assets. Yukiko, who went by the name Violet Rose, was also one of the Purple Kingdom's most valuable comrades. She was stronger than Snake at level 6.
They both fell in love while they spent most of their time in Brain Burst. Even though they were only together for about two weeks, in Brain Burst they were together for years. The two of them were inseparable; you never saw one without the other.
One day, the Purple King assigned Rose to a mission. She thought Rose, at her level and skill, was the only one capable of completing this assignment. Violet Rose was assigned the task of hunting down and destroying the treacherous Black King, Black Lotus.
In the accelerated world, she'd been gone for a year. Ebony Snake was worried; he hoped that she was okay. Three days later, he received word that Violet Rose had failed her mission. Snake was surprised, Violet Rose had never lost a battle, and she was undefeated in every single fight she's been in since Snake came to the accelerated world. He didn't realize just how powerful the Black King could be to defeat her, but she wasn't just defeated, the Black King was merciless, and beat her until she lost all of her Burst Points.
When Snake had heard that Rose lost all of her Burst Points, at first he thought it was okay, even though she can't return to the accelerated world, they could still be together in the real world. He decided to return to the real world and try to see Yukiko.
When he saw her at school the next day, he tried to talk to her. She looked at him and greeted him. "You're Natsuki right? Hello, I'm Yukiko Kageyama." He was devastated. They had fallen in love in Brain Burst, because she lost her memory of the game, she forgot about him.
Ebony Snake spent the whole year training until he was level 6. The next year, he heard about a fight that was going to happen between a member of the Blue Legion and a new player. He went and watched the fight, he was interested to see what this new player was capable of, and maybe he could convince him to join the Purple Legion.
The combatants were known as Silver Crow and Cyan Pile. Silver Crow had the extremely rare ability to fly, Snake found this to be interesting. Then when the fight neared the end, he saw a girl in the distance. She looked familiar, he thought he'd met her somewhere before. He saw butterfly wings and immediately he recognized her. It was none other than his ex-girlfriend Kuroyukihime. Snake had no idea what she was doing here, then he saw the most terrifying thing he'd seen in this game. Kuroyukihime transformed into the Black King, Black Lotus. Snake couldn't believe his eyes, the one who destroyed his relationship with Yukiko was Kuroyukihime. He knew what he had to do. He was going to take revenge on the Black King and avenge Violet Rose.
