My first SAO fanfic. I've read a few on this site and figured I should try it. AU possibly idk. Kirito is pulled into more trouble converting to another virtual game. Yui will appear in the first chapter, but I'm not sure if it should be AU enough to have her in the same game as Kirito. Also, something that's been bothering me. I've been rewatching Season 2 Episode 7 and I can't figure this out. How is Yui with Asuna and the others in ALO if Kirito isn't even using his NerveGear? I'm not sure how that works. Maybe Asuna is holding his items for him while he's away. Or can Yui move freely between the virtual realms? So if anyone can tell me in the reviews, that'd be great. This will be from Kirito's POV. Think of this as another sidestory. I disclaim all SAO characters.

Kazuto's House

It was just another peaceful day. Waking up one morning ready for anything, I headed downstairs. "Sugu, you down here?" I asked. Just then, my cousin, Suguha Kirigaya jumped up. "Kazuto. I was about to wake you." she panicked. "You sure seem surprised."

It was a shock finding out Suguha was also Leafa in ALO. I really didn't expect her to be in virtual gaming like I was, but she was a big help in reuniting my family. Just me, Asuna, and of course Yui. Since meeting Asuna, things have been pretty smooth lately.

I had a light breakfast and told Sugu I'd be back in bit. "Where's Asuna?" she asked.

"Knowing her, she's probably at the school's front gate waiting for me." I tell her.

"Don't forget, Kazuto. We need your help on another quest later."

"I remember." Thing is, ever since the World Seed was planted and virtual games one after another emerged, I remained with Alfheim Online for the most part. Until Seijiro requested I uncover a conspiracy occurring in Gun Gale Online. That's how I met Shino Asada. Since then, she's been accepted by my fellow SAO survivors, Yui, and Sugu. If I thought I could happily return to ALO and continue the domination of New Aincrad, little did I realize, I was about to set out to take part in a new virtual game.

SAO Survival School-Main Gate

I arrived at the gates by the SAO survivor school and Asuna had also just shown up. She runs right up to me, like usual. "Kirito, I thought you'd get here til later." she told me. "I wanted to surprise you by being on time."

Asuna knew I was different, but she always knew I'd surprise her no matter what I did. From the SAO days to me conquering the World Tree when we first entered ALO. How would she feel if I got called into another different game? "Asuna...?"

"What's wrong?" She looked nervous. Do I tell her now or in Alfheim? "Something I need to let you know..." I felt down but not quite out. "We should wait a bit until we're all together in ALO after I get all the info." Asuna's hand went down my arm lightly pulling my hand toward her.

"If it's anything groundbreaking, you know you're not alone, right?" She always had a way of showing me I didn't have to worry about much. Those hazel eyes were always so hopeful telling me without words that everything would turn out all right. "Chrysheight is requesting my services again."

"Another game transfer? Kirito, you just came back alive fighting Death Gun in GGO. Now Seijiro's pulling us apart again?" She let out a saddening sigh. "I'm sure he has his reasons."

"I'm meeting with him later to discuss the situation in the new game. You're free to listen in." I assured her. It was decided. We would wait to tell the others, and we will tell them this time."

Outside the JDSF

It was just another very calm morning for us. Before we knew it, we stood before the JDSF. "Why, hello, Kazuto and Asuna." Seijiro greeted us. He filled us in quickly on the virtual game he needs me to investigate. "As you can see, the players use musical instruments in combat as solo players or in parties. And there are divisions for both choices. It's called MBO, Music Battle Online."

"So what I'm understanding is anyone who accesses MBO has any instrument they want?" Asuna said quite intrigued. "But you can't go alone, Kazuto. You'll have to choose someone to accompany you. There is quite the confrontation happening, musically of course. And it might be too much for you to do alone." said Seijiro. I took a moment to take in all the concepts of MBO, from the music genres to choices of instruments. What would be my music style and instrument? What would I have to do when I got there? What I knew was, I had to find out who would take the plunge. But, wait a minute. That means someone from ALO would have their character reset like what happened with me last time.. Who would be the most willing? Asuna and I would have to let everyone know so we can make the best decision as a group.

"Ok. I'm in." I informed the detective. "Brilliant! You can tell me who you'll take into your new virtual battlefield when the decision is made." he informed us. We were about to head back to ALO when we thought of what we would say to the others. "How do you want to tell them?" I asked. Asuna still had that look of uncertainty. "We need to be upfront with them, they're probably still sore about you not saying anything to them about converting the first time." Asuna reminded me. "Now what's wrong?" I looked down again. "Just thinking, how's Yui gonna take this?"

"You're right. She'll probably be lonely without our family together."

"I mean, I was only away for a few days last time, Asuna. And you can't die in this game. How bad can it be?"

"Not sure, but let's get the word out. See you in a few?"

"I'll be there." I pull Asuna toward me, my arms circling her waist in a deep kiss. It might only have been for a second but it told her something I didn't need to say.

Alfheim Online-After the quest

I decided to go over what to tell the others with Asuna, or as she was now called in ALO, Erika, an Undine Healer, as well as our daughter, Yui. "Who do think will do it?" Asuna asked looking over at the others. "Let's see. Klein might be busy clearing New Aincrad with the Salamanders. Lisbeth probably can't help being a blacksmith, she might not know about instruments. I can't ask Sugu since she doesn't know much about music. Sinon just started here in ALO, it wouldn't be fair to have her switch games so suddenly. Silica back in SAO played an instrument, but she might get too nervous. This is harder than I thought."

Yui circled around me trying to ease my thoughts. "You have an idea, Yui?" Asuna asked. The young girl blinked a few times focuing on Asuna. "Well, if the others can't leave here, what if you go with Daddy instead."

"But what about you? I can't stand the idea of you lonely without us." Asuna said worried.

Yui assumed her normal SAO size hugging Asuna like she did when we rescued her the first time we came here. And I arrive to hug them both. "Don't cry, Mommy. If you go, I'll make sure nothing happens to the others." She gave Asuna the 'eyes' that she gave me before that lit up her smile.

"Thank you, Yui. It's sweet that you would protect all of us." she responded.

"Let's see what the everyone else has to say." I inform them. We finally rejoin our ragtag brigade, ready to tell them everything. They wondered what we talked about earlier.

"All right. We have something to tell you all."

How will the others take it that Kirito is converting again? And who will be there with him? Should it be Asuna or maybe someone else? Review your thoughts so far, favorite, follow and I'll do what I can to continue the story.
