Kirito

I was completely stunned of seeing my adoptive daughter, Yui. "What the- Yui?!?" I exclaimed as the pixie ai smiled at me as that she was relieved that i was all right. "Papa, you really outdid yourself." 

I raised my hands in defense, "Hey! I really didn't mean to be in the Underworld I swear! Although, i'm curious. What happened to my body? Is it ok?"

The girl nods, "Yep. Mommy is taking good care of you as we speak. She is worried about you and what you've been doing in this world." 

As i was about to explain of what is happening, Eugeo yelps in surprise of seeing her. "K-Kirito, who is that pixie?!? 

She really looks like you both know each other." 

"Of course he knows me! I'm his daughter after all!" She said in a proud tone which I grabbed her little wing to tuck her into my corner pocket from anyone around us noticing us. 

As Eugeo watches our interaction, he sweats, "So... she's from the real world i suppose?" 

I sigh of how much trouble I would be with Yui being in this world, as we head into our dorms to talk more in private matter. 

I pulled her out of my pocket as the little pixie pouts at me for putting her inside it. "Daddy, that's pure cruelty!" 

Eugeo

I was a little bit surprised of seeing a pixie showing up to us like this. The little pixie is pretty upset by Kirito. I guess that this is part of the Kirito I haven't seen over the last sixteen years. 

I coughed to get their attention as that Kirito sighs as that there was no point of keeping in a secret from me. 

"Eugeo, this is my AI daughter, Yui. As you might've guessed, she does come from the real world as I do, although, I was kind of a protective father. 

Yui, this is my childhood friend, Eugeo. He's helping me here in the Underworld to rescue our other childhood friend, Alice who has disappeared." 

"A friend of Daddy's? Wow, I guess that there is a lot about you that Mommy and I don't even know about." 

I sigh but I was curious about what is an AI. "Um, Kirito, what is a "AI"? She's different than us?"

The teen sighs, as to knowing talking about his past seems kind of awkward, as he replied, "Well, kind of. They're advanced personal aid so to speak. Yui is special case. It's because she was originated from SAO, her data is pretty high standard stats. 

Asuna and I had no idea at the time she was an AI at first, but now, she's our adorable, headstrong daughter."

I was totally impressed of how much Kirito really cares about her, as though it gave me some thought. 

"Hm.." I muttered, as Kirito and Yui looked at me with curious expressions on their faces. "Is something the matter?" Yui asked. 

Yui

I'm very glad that I found Daddy in the Underworld, and that he was all right. I guess Mommy was worried for the right reasons. 

Although, it appears that in this world, he has friends that even i didn't know about. Eugeo, was thinking about something. 

I asked, "Is something the matter?"

He seems to be lost in total thought, as then he begins to look serious as that he was concerned about their missing friend. 

"Kirito, do you think it's possible that Yui can use her tracking AI skills to help us in the Capital?" 

Daddy seems to be aware of what he was suggesting. "Using an AI as a beacon to locate Alice, is that your suggestion?

Eugeo, your suggestion might cause some problems if we do that." 

"Do you have any bright ideas, Kirito? I mean, having her here must be very important, and you experienced a lot through SAO, am I not wrong?" He asked. 

The black haired teen sighs, as that he had no other choice. "Gee, how come you have to be so stubborn?" 

Eugeo said, "I learn it mostly from you! You're the stubbornest person I have as a best friend. Kirito, no matter what, we are going through this mess together." 

I said, "I'll do my best. Right now, I sense something else." 

We both turned to the pixie, "Really, Yui? What is it?"

"Well... I don't know how to describe it. It feels like a disturbance in the Underworld." I  replied in a worried state.

"Let's investigate." Daddy said, as he puts me back into his pocket, and leaps from a nearby widow! 

"Kirito! Wait for me!" Eugeo cried out desperately as I grabbed both of our swords in case we got involved with a fight with uncomfortable suitors.

The two swordsmen follows my lead, as the source of the problem was getting very close. "Yui, how much further?" Eugeo asked. 

Daddy seems to be disturbed, as he spots something scary. "Eugeo, look at that." He points towards a windowsill, as that to his greatest surprise and horror, that there was two girls being tied up and hold against their will.

"It's Tiese and Ronye! They are in mortal danger! What shall we do?" He asked in a panic state. Daddy said, calming his friend down, "Eugeo, it's going to be ok. We'll save them somehow. Let Yui scout the area for anyone suspicious coming. Can you do that, sweetie?"

"On it. But what you going to do?" I asked.  "Your daddy and Eugeo will try to get to the girls without breaking the school rules." 

Eugeo sweats, "Why you act like it's not a major thing with you? Do you realize how much trouble we'll be in?!?"

He ignored his complaint as that he went ahead, as he turns to me, "Was he always this reckless back at your world? 

I feel bad for Asuna to go through with him."
