K-Online: A Sword Art Online and K-On Crossover

Chapter 1

"Sword Art Online, huh?"

Understandably, Mio Akiyama was quite hesitant to try out the new game. Mugi was able to get her hands on her own Nerve Gear (and a few units for each of them), but will be out of town for a few weeks. Yui and her sister Ui were visiting other relatives, while Azusa was going to be at Training Camp with the Light Music Club.

So, that left Mio and her good friend Ritsu Tainaka as the only members of Hokago Tea Time to play Sword Art Online, the newest gaming craze to sweep the Japan. Ritsu was able to secure accounts for both of them early on, intending to drag her along for the ride. They agreed to meet up online over Spring Break to try out the game.

"It's crazy!" Ritsu said over the phone as she watched the news. There were literally hundreds, even thousands, of people lining up the stores for hours just to get their hands on the new game. "We're lucky that Mugi got her hands on that game, otherwise we'd be lining up as well!"

Mio nodded, though her brown eyes reflected uncertainty. "The only reason I'm going to play was because you dragged me into this, Ritsu." she sighed. Plus, she isn't as into game as Ritsu was, so understandably she was apprehensive of playing an online game.

"Aw c'mon, Mio!" She pleaded over the phone "It'll be fun, I promise!"

Mio chuckled at that response. It was the same back then: Ritsu dragged her along to join the Light Music Club back when they were High School freshmen. The rest, as they say, was history.

"Alright, alright." She sighed in defeat "I'll give it a shot."

"I'll see you online, then!" Ritsu said cheerfully before she hung up her phone. "Oh, Ricchan." Mio chuckled as she put down the phone "She'll never change..."

She turned on her new Nerve Gear and got it warmed up. Excited, she put it on, a small smile showing on her face.

This might be fun after all...

After finishing the tasks of logging in to your account (She nearly forgot her password) and choosing an in-game name for herself (She settled on her own name after seeing that "Elizabeth" was taken), Mio finally got inside the game. She looked around, then lifted up her arms.

S-sugoi*! She thought in awe. She could feel her neck turning and her arms moving as it would in real life. She took a short walk around the town and, to her amazement, she could feel as if she were lifting her own legs in the real world.

She took a stroll to the fountain and looked at her reflection. She was surprised, for she found that her appearance changed somewhat. Her frame was taller, and her face had a more mature air around her. If anything, she looked much like a twenty seven year old version of herself.

"This is amazing..." She said out loud, dumbfounded by the wonders NerveGear had shown her so far. "For the programmer to accomplish something like this. It's unbelievable!" She looked around to find many other people popping up before her, new players logging in to their new accounts to start their new adventure.

Which reminds me, Mio thought as she made her way through the town. I have to find Ricchan!

~0~

It had already been an hour, yet there was no sign of Ritsu anywhere. Sighing, she made her way out to the fields just so she can get a feel on how to use the game's battle system.

The only problem was that being the scaredy-cat she is, the Frenzy Boars absolutely terrified her. This did not help one bit when one of them was chasing her all over the field.

"RITSU, WHERE ARE YOUUU?!" She wailed as the her opponent gave chase "I WANNA GO HOME!"

After twenty minutes or so of this, she was eventually caught between a rock and a hard place as the boar cornered her. Seeing that she had no choice but to fight, she drew her Beginner's Sword and held it in front of her. Her arms were trembling in fear, barely able to hold her weapon in her grasp.

"D-don't come any closer!" She stammered, her eyes wide and her legs shaking. Smelling her fear, the boar stalked her. The closer it got, the more Mio trembled. "S-stay back!" She threatened, but was failing as the boar slowly came nearer.

This is it. Mio thought to herself, completely forgetting that if you die in a video game, you can always respawn. I'm about to become pig food.

She closer her eyes and braced herself for a blow, only that it never came. She opened one eye when she heard it squeal in pain, only to see that it was struck by a rock.

"Are you okay, miss?" She looked at her saviors; two males, one with short black hair and one with long red hair and a bandanna over his head. "I-I'm fine." Mio sighed in relief, looking at the two gratefully.

"We'll grab it's attention." The black haired boy called to her "You go in for the killing blow."

"B-but I can't..." Mio stammered, only to receive a grin from the redhead "It's alright." He told her "I got my butt whupped by one of these things earlier. Just do as I do."

He took a deep breath and positioned his blade behind him. After a slight delay, the sword began to glow. Using that moment to strike, he slashed at the Frenzy Boar, damaging it greatly but not killing it.

"Your turn!" He called out to Mio "When using your Sword Skill, just charge it until it's ready, then let it explode!"

She nodded, and got into position and took a deep breath. Sure enough, her own weapon began to glow. The other person nimbly dodged the boar's charge and jabbed it's side. With it's HP in the red, it charged at Mio in desperation, singling her out as the weakest.

It never saw what was next coming.

"HA!" With a roar of determination, Mio thrust her charged blade right at the Frenzy Boar, reducing it's lifebar to zero. As a result, the boar vanished into thin air and a window popped up showing her the experience and col she won.

In her amazement, Mio dropped her sword. "I...I won." She turned to the other two with glee in her eyes "I won!" She ran and glomped them both "Oh, thank you so much! My name's Mio, by the way."

"No problem." The redhead patted her back "It's no big deal." He smiled as she pulled back "The name's Klein, and this guy's Kirito. He was a beta tester and he's been teaching me a lot!"

Confused, Mio cocked her head to the side "Beta Tester?"

"It means that he tested the game out first, silly." Mio turned to see Ritsu, her hair longer and looking older as she was, grinning. "R-Ritsu?!" Mio exclaimed, pointing at her friend shocked. "Call me Taiga now!" Ritsu pointed a thumb at herself with a confident air around her "Like, you know, a tiger!"

"How did you find me?" Mio asked her friend "I was looking all over for you!"

"Well, you're the only I know who'd use her actual name for a game." Taiga chuckled "Which is lame, by the way."

"Very funny." Mio pouted, then remembered that Kirito and Klein, who were just staring at them. "Sorry." She laughed sheepishly "This is Kirito and Klein. Guys, this is Ri- I mean, Taiga. They just taught me how to fight here."

"Nice to meet ya!" Taiga waved at them. "So, you were Beta Tester, huh?" She grinned at Kirito "So cool! Only a thousand of people got that chance! I'm so jealous!" Kirito laughed nervously in response. "It's nothing really..."

"Hey, don't short change yourself!" Klein laughed as he slapped him hard on the back "If it weren't for you, I'd be getting my ass handed to me all day!"

Mio couldn't help but smile; in her first day in SAO, she had already made two new friends.

"C'mon!" She got startled when Ritsu grabbed her hand "I wanna see more of this place!"

"O-okay!" Mio got dragged along, but still had time to turn to Kirito and Klein, who waved at them "It was nice to meet you both! Hope to see you again!"

Hours Later...

"Ah, this is the life!" exclaimed Taiga as she dropped on the meadow with a thud. Mio just shook her head while letting out a small laugh. This was typical Ritsu. Always so easy-going, always so cheerful. That's one of the reasons why Mio cherished their friendship, for she can always put her at ease whenever she was troubled.

"Say," Taiga said thoughtfully "If this game allows us to play music, we can get the others in here! Hokago Tea Time goes digital, baby! We'll be virtual rock stars!" She pumped her fist in the air with a grin for emphasis.

This caused Mio to laugh out loud. "You might be right." She chuckled as she lay beside her friend "This could be useful for publicity. If we perform enough, we might get some fans."

"See?" Taiga nudged her happily "I told you you'd like this game." This caused Mio to sigh "Alright, alright." She replied with a smile "I suppose you can get it right every once in a while."

"Don't I know it!" Taiga chuckled "Man, what a day, huh?"

"Yeah..." said Mio thoughtfully "This game is amazing." Taiga nodded in agreement. At that time, the sun began to set.

"Will you look at the time?" Taiga chuckled "It's already sunset." Her stomach rumbled as a result. "That's right!" Mio sat up as if she was jolted "I have to prepare dinner soon!" Taiga sighed "Looks like we'll have to come back later."

"And bring the others with us too." Mio chuckled, her in-game menu creating a ringing sound as she accessed her options. "Uhm, Taiga?"

"Yeah, Mio?" She sat up, her eyes had a questioning look towards her. "Where's the log-out button?"

"Are you serious, Mio?" Taiga sighed, remembering that it was Mio's first time with this kind of game. "You just go to your menu like this end..." Her eyes widened in shock when she found an empy slot where the log-out option was supposed to be.

"This can't be right..." Taiga said quietly "There should be a log out icon here..."

"What do you think happened?" Mio wondered aloud "Most likely a bug." Taiga said thoughtfully "Or a glitch that the system administrator is taking care of."

"Can we try to remove the NerveGear ourselves?"

"I doubt it. From what I read, it intercepts what actions we do outside and apply it to the game. That means all we can do is wait. I mean, it's the game's first day. There's bound to be some slip ups. I suppose all we can do is wait."

Mio nodded quietly in agreement. Though, truthfully, she was getting a very bad feeling about this...

~0~

At that moment, the bell began to ring ominously.

"What's going on?" Mio asked Taiga, who shrugged "I wish I knew." She replied. Mio gasped in surprise when a blue light engulfed her, causing her to vanish without a trace. "Mio!" Taiga called out to her friend, only to find that same blue light engulfing her as well. "What the-?!"

They both found themselves at the Town of Beginnings, along with the countless other players. Mio noticed that they were just as confused as she was, hearing murmurs such as "What's going on?", "What are we doing here?" and, most importantly, "Why can't we log out?"

"Hey, isn't that Kirito-san and Klein-san?" Mio whispered to Taiga, who nodded in response. "Hey guys!" They both turned to see the girls approach them. "Mio-san! Taiga-san!" Klein greeted them. "Hey! Do you know what's going on?" Taiga asked them both.

"Afraid not." Kirito sighed, then took a look at beeping red icon that said "Warning" on the sky. "Though I think we're about to find out..."

Suddenly, an alarm sound filled the air as many of those icons covered the sky, blanketing town square in an eerie red glow. "What now?!" Taiga said as she watched the skies worriedly. Soon enough red slime came oozing out of the icons.

"I think I'm gonna be sick." Mio's face looked pale, the image of the ooze pouring out not agreeing with her stomach. The slime joined together and eventually formed a giant man in a huge red cloak. Mio clung onto Taiga tightly, her eyes wide with fear. The man had an eerie aura about him.

"Attention, Players!" It bellowed in a deep voice "Welcome to my World!"

"'My world?'" Kirito asked quietly "Something tells me that this isn't an event..." Taiga said, never keeping her eyes of the man.

"My name is Kayaba Akihiko, and as of this moment, I am the sole person that can control this world."

Ignoring the stunned murmurs around him, he continued "I'm sure you've already noticed that your log-out button is missing from your main menu."

"Yeah, what's up with that?" Taiga shouted at the figure "Is it a bug or something?" The robed figure just chuckled as a response "Nothing of the sort. It is not a defect of the game. I repeat, it is not a defect of the game. It is a feature of Sword Art Online."

"F-feature?" Klein said quietly, his face showing his shock. Mio gulped, slowly comprehending the hooded man's words. "You cannot log out of Sword Art Online by yourselves." He continued "Also, no one on the outside can remove or shut down the Nerve Gear. Should this be attempted, the transmitter will emit a powerful microwave that will destroy your brain and end your life."

Many panicked murmurs sounded from the assembly, with some trying to leave only to find themselves blocked by a force field. "He's gotta be nuts, right?" Klein asked the others. "He's right that the transmitter's signals work like a microwave." Kirito answered "If the safety were disabled, it could fry a brain."

Mio's face paled at that image. "Can't we try and turn it off?" Taiga asked him, who just shook his head "That won't work. The Nerve Gear has an internal battery." All their eyes widened at that revelation. "This is crazy!" Klein exclaimed "What's going on?!"

"Unfortunately, several player's friends and family ignored the warning and have attempted to remove the NerveGear. As of now, 213 players have left us, both from Aincrad and the real world, forever."

"Two hundred and thirteen?" Kirito said in shock "No..." Mio's eyes widened, reflecting the fear and hopelessness she felt.

"As you can see," Various newsfeed depicting reports of the incident, the deaths included, began popping up around him "All this, including the deaths, are being reported all over the world. Thus, we can safely assume that the danger of removing the Nerve Gear has been reduced to a minimal. I hope that you will relax and attempt to clear the game."

"This is crazy..." Taiga growled, her body trembling with rage. "But I want you to remember this clearly: As of right now, there is no longer any method of reviving yourself within the game. If your HP drops to zero, your avatar will be forever lost. And simultaneously...The Nerve Gear will destroy your brain."

Mio and Taiga gasped at what they heard. They immediately realized that this was no mere game anymore. It had essentially become a fight for survival.

"There is only one means of escape: Clear the game." The robed figure showed them a diagram of the game. "Currently, you are at the lowest level of Aincrad. If you manage to defeat the floor boss, you can advance to the next level. To beat the game, you must defeat the Final Boss at Floor 100."

"Clear the game?" and such were heard all over the town square. "He's nuts." Klein growled "The beta testers never made it that high!"

"Finally," The hooded man said "I've added a present from me in your item storage. Please see for yourselves."

Everyone proceeded to check their inventory, only to find a Mirror. "Huh?" Taiga asked "What's this?" She quickly turned when Mio screamed, seeing her engulfed in blue light. "Mio!" She managed to shout before being immersed in light herself, as did everyone assembled in the town square.

"A-are you alright?" Mio turned to Taiga "I'm fine, I'm fine." She responded, only to blink in surprise at her friend. "What is it?" Mio asked, looking shocked then immediately looked at the Mirror again.

"I-I'm me?!" She gasped when she found that she reverted to her appearance in the real world, then turned to Taiga, who's appearance also changed "And you're Ricchan again!"

"I know!" Taiga exclaimed "What's happening now?!"

"It's the Nerve Gear." They both turned to see Kirito, whose appearance changed into a boy just about their age "It covers your face in a high-density signaling device. So, it knows what your face looks like."

"Howabout our bodies?" Mio asked "How did it manage to copy our bodies exactly?"

"Hang on," Klein spoke up, his appearance reverting to having shorter hair. "It had us calibrate when we first used it, right?"

"Yeah. You had to touch your body all over." Taiga nodded in agreement "That must be how it copied our bodies."

"But why?!" Mio asked, tears welling up her eyes "Why go through all this?!" Kirito hushed her and pointed at Kayaba "Maybe he'll tell us."

"Now, I bet you're wondering: 'Why?' Why would Kayaba Akihiko, the man who developed Sword Art Online and NerveGear, do this? My goal has been achieved. I created Sword Art Online for one reason: To create this world and intervene in it."

"Kayaba..." Kirito growled, glaring at the figure. "Now it is complete." Kayaba said as he surveyed all that was around him. "That concludes the tutorial for the official Sword Art Online launch. Good luck players." With that chilling line, he began to dissipate in smoke, and the sky immediately returned to normal.

For a moment, there was complete silence. "N-no..." Mio dropped to her knees and broke down, her tears and her despair pouring like a waterfall. "Yui-chan, Mugi-chan, Azu-nyan...I'll never see them again..."

"Mio-chan..." Taiga looked at her friend sadly and wrapped her arms around her. One panicked scream later, pandemonium broke out. Shouts of "Screw this!" and "Let me out of here!" echoed the square as players shouted and yelled, knowing that Kayaba can hear them.

"Come with me, Klein." Kirito grabbed him by the arm. "B-but..." He looked at Mio and Taiga, the latter who just smiled at him.

"Go on ahead," She reassured them as she held Mio tightly "We'll figure out our own thing. Don't worry about us. We'll meet again." The two nodded at them, Klein smiling gratefully, then went on ahead.

"R-Ricchan..." Mio sniffed, crying on her friend's shoulder "We'll die here...We'll never see our friends again..."

"No we won't." Taiga said firmly as she pulled back, holding Mio by the shoulders "And yes we will. We'll fight our way out. We'll finish this game, no matter how long it will take. And we'll do this together, like we always have."

"T-together?" Mio said, sniffing a little. "Yes," She smiled softly at her "Together. Now, let's stop lying about here and get to the next town. Everyone's going to be farming like crazy here..."

"Yeah, you're right." Mio finally smiled, wiping the tears away "Thanks, Ricchan." She gave her friend a tight hug "You always know how to cheer me up."

"No prob." She chuckled "And it's Taiga here. Remember?"

"Oh right." Mio chuckled back. Taiga offered her hand to me "So, shall we?"

"Do you even have to ask?" Mio giggled as she grabbed her friend's hand. They ran out of town and, thus began what would be their greatest adventure.
