It's been two weeks since the Death Gun incident. Everything seems returned to normal. Naruto continued to work on his grand project with the help of Jiraya and some people. Naruto managed to convince Sinon to join ALO, so that she won't felt lonely anymore. The day after Naruto brought Shino to the Dicey Cafe, he decided to visit Suguha with Shino. There he explained the situation to Suguha and she accepted without complain. Now, we see Kazuto and Suguha situation at the table eating breakfast.

Kirigaya household

Suguha looked at his brother as he yawned tiredly and asked.
"Were you sleep late again onii-chan?" Asked Sugu.
"Yeah, homework for school, mechatronics" answered Kazuto tiredly. Then turned his head to the TV

Then Sugu turned on the tablet, she noticed something interesting and called her brother.
"Onii-chan! Look!"
Kazuto looked at the screen and read the article. Then he shouted in surprise.
"What? Someone found the Holy Sword Excalibur?!"
Then he sighed in disappointment and said.
"Someone finally got it huh?"
Sugu rolled her eyes took a bite and said.
"Read more intently. It's only been found. And that's all. No one actually managed to find it"
Kazuto sighed in relief then said.
"Really? Well, don't scare me like that"
Suguha just nodded her head while chewing the sandwich.
About several months ago, Kirito and Leafa were swallowed by a giant worm on the Arun plateau. After that they were dropped the the underground world by the name Jötunheimr. There they saw a giant Tyrant-class humanoid with four arms attacking a Tyrant, that looked like the combination of the elephant and the jellyfish. Leafa felt pity towards the white creature that was being bullied, asked Kirito to help it. Then Kirito managed to bait the giant with four arms to the lake so the white creature managed to finish it off. Leafa decided to name the creature 'Tonkii'. It grew eight wings and carried them to the path to the upper world. On their way, they saw a huge pyramid-like labyrinth that was upside down. Kirito looked at the bottom of the pyramid and noticed the Holy Sword Excalibur was at the bottom.
"I actually plan to get it someday, but..." said Kazuto looking at the screen.
"You've been spending all time on New Aincrad. By the way, do you think that Excalibur can fight equally with Naruto-kun's Kusanagi?" said Sugu pouring the milk to the glass and asked.
"Hmm, I don't know, but I think they are equal. Excalibur is not known as the strongest sword in ALO for nothing. On the other hand Naruto's Kusanagi is also a legendary blade that is unbreakable. It will be good to test those swords strength in a test fight" said Kazuto in a thinking pose.
"By the way how did they manage to find it? You can't actually fly in Jötunheimr. You need to be a master of transportation magic like Naruto or fly on the giants with wings to get there?"
"Well, I think that someone also saved Tonkii's friends like us and flew to the labyrinth like us" deduced Suguha.
"If you say that it actually made sense. That creepy..." said Kazuto but he stopped when looking at the narrowed displeased eyes of Suguha.
"N-no, the unique appearance that that Tyrant has means only a weirdo..." continued Kazuto but again was stopped by the displeased gaze of Suguha.
"I-I mean a very nice person... would save it. And you are not the only one" finished Kazuto while still felt nervous at Suguha's displeased gaze.
"He isn't creepy. He is cute. But that means it will be a matter of time until someone clear the dungeon and gets the sword" retort Suguha then said.
"Yeah, you are right" muttered Kazuto
"What will you do, onii-chan?" asked Suguha.
"I actually want to obtain that sword and have an all out fight with Naruto, to see our limits. Also maybe Tonkii wanted us to find the sword that's why it showed it to us" said Kazuto with an excitement in his voice.
"Heh? An all fight with Naruto-kun? Why do you need something like that?" asked Suguha in bewilderment.
"I've wanted to battle him since SAO. But I don't have the strong enough weapon and skills to challenge Naruto. I spend my time in New Aincrad to sharpen my skills so that one day I could fight Naruto with everything I got. With Excalibur I can do that. I want to know my limitations and where I stand compare to Naruto" explained Kazuto with a serious face.
"Oh, I'd like to see the match. And of course I will cheer for you both" said Suguha smiling.
"Are you free today Sugu?"
"Well, my club is off for the rest of the yeah"
"Alright, then we will gather a party to clear the quest. There can be up to seven people ride on Tonkii, right? But Naruto can use his transportation magic, so he could transport himself to the labyrinth, while we ride the Tonkii. Except Naruto, there are me, you, Asuna, Lisbeth, Sillica, Klein..." said Kazuto.
"You forget about Shino-chan. That will make 8 people in the party while Naruto-kun will use a transportation magic to move himself. I will contact Naruto-kun and the others. Asuna-san is up to you, onii-chan" said Suguha and prepared to contact the others.
"Ok"

Yuuki household
Bathroom

Yuuki Asuna is currently taking a bath while thought.
'I actually want to see Kirito-kun once more before I return to Kyoto. Also Naruto was so busy the past time in his project that he basically never home'
Suddenly, she heard a ring from her phone and respond.
"Hello? Kirito-kun?"
"Good morning, Asuna. Do you have a moment? This afternoon, I want to do a quest with everyone in ALO"
"I am free all day today"
"Alright. Then I will send you the message with the time and place we are meeting. If you see Naruto inform him as well for me ok?"
"Ok, then I will see you on the other side ok?"

Naruto's old apartment

Naruto and Jiraya currently working on Naruto's grand project by the name of Shinobi World Online, so far the environment and the five main village were created. Though there were still more work need to be done. Naruto is working on creating the specific clans once you are at the specific level you can join in to learn unique technique if each clans. Though you can enter only 1 clan and learn the techniques of that clan.
Suddenly, Naruto received a call he looked at who called him and saw it was Suguha. He answered.
"Sugu-chan, how are you? Is something happen?"
"Hello, Naruto-kun. If you are not busy I'd like you to join us for the quest in Jötunheimr"
"Well, I actually..."
But he was interrupted by Jiraya.
"It's alright to take a break once for a while"
"Ok, I will be there. Just tell me the time and place where we will meet"
"Ok. I will send it to you later. See you on the other side Naruto-kun"

Time skip
ALO
Meeting place

Kirito, Klein, Sinon and Silica were already at the meeting place. They are waiting for the others to arrive. Well actually Asuna and Leafa go for a shopping, Naruto though is unknown.
Klein took a sip of beer and sigh satisfyingly.
"Are you already on break for New Year's, Klein-san?" asked Silica.
"Yeah, from yesterday. Even if I wanted to work, at this time of year, nothing comes in. The CEO just keep bragging how great we are, to have the whole week off for New Year's... Hey, Kirito... If we do get the Excalibur today. I'd like for you to help me get the Spirit Blade Kanezuchi. After all it's not fair that only you and Naruto get the legendary weapons" said Klein then turned to Kirito.
"That dungeon is so freaking hot, though" complained Kirito.
"What are you complaining about? In Jötunheimr is freaking cold too" complained Klein pointing at Kirito.
"Then I know what I want... The Light Bow Shekinah" said Sinon.
Kirito looked at Sinon and asked incredulously.
"You only had your character for two weeks and already aimed for rare weapons?"
"Well, I get that from Naruto. On the first day, he logged in GGO and get the Hades Revolver XIII. I am still amazed at his luck. The bow Liz made me is wonderful, but the range not really satisfy me" said Sinon with rolled eyes then closed her eyes and continued
Lisbeth fixing the weapons hearing that respond.
"Listen, in this world bows have more range then spears, but have less range then magic. And you're the only one trying to hit the target from hundred meters"
"I wonder if Naruto will come. He said he was very busy with his project, even with assistants" wondered a blue haired Caith Sith.
"Well, Leafa called him and he said that he will be here. I think he wanted to make a dramatic appearance. After all he is the only one in this world that fully masters the transportation magic" said Kirito and rolled his eyes at the thought.
Lisbeth, Sinon and Silica laughed at that . Then Lisbeth said.
"Yeah, that definitely Naruto-kun. Trying to show off and make grand entrance. Nearly two years passed and he didn't change one bit"
Suddenly, the door opened and Asuna with Leafa entered, with stuff in the baskets.
"We are here!" said Leafa
"Sorry, for the waiting" said Asuna
Leafa then looked around and asked.
"Naruto-kun still not appeared? I wonder if he will actually come"
Just that suddenly behind Sinon, a shadow slowly appeared from the floor. Naruto makes a silence sign, while the other trying to suppress their laugh at what about to happen.
Sink still didn't noticed anything, but looked at the other weirdly as they tried to suppress their laugh. She raised her eyebrow and wondered what happened.
Naruto had a huge smirk on his smirk and shouted loudly behind Sinon's back.
"Boo!"
"Ahhh" shouted Sinon startled and on instinct jumped to the ceiling in fright.
The other couldn't hold their laugh anymore and released it. Sinon glared hateful at Naruto who is on the floor laughing like a maniac.
"Naruto.,." muttered Sinon with gritted teeth.
Naruto stopped his laughing and paled. He just realized that he just pissed off the wrong person. And just that he take off outside with blinding speed. Sinon immediately pursuit him and took out the bow and fired at Naruto simultaneously. Naruto dodge each shot and said.
"I am *dodge* sorry. It was *dodge* just a *dodge* harmless joke. Don't *dodge* take it too *dodge* seriously"
Yui sitting on Asuna's shoulder and Wendy on Leafa's looked at the scene and laugh.
"Uncle Naruto is so silly!"
"Yeah, tou-chan is silly to piss off Sinon-kaa-chan like that"
When Sinon has calmed down they walked back to the house. Though she still send some glares to Naruto for the stunt he pulled. While Naruto just laughed nervously and scratched his head.
"While we were shopping we managed to gather some informations. It doesn't look like any players or parties have made it to the mid-air dungeon, Papa" said Yui and land on Kirito's head.
"Then how did they found the Excalibur location?" asked Naruto still being glared by Sinon.
"It seems that someone recieved the different quest then the one we took with Tonkii-san. As a reward the NPC showed them the Excalibur" answered Yui.
"And it seems its bit a peaceful quest either. It was a slaughter-type quest, in which you try to kill equal or more monsters then request. And because of that, everyone in Jötunheimr are trying to kill as much monsters as they can" explained Asuna.
"Definitely not a peaceful quest... But I see someone is excite here" said Kirito then sweat dropping turned to the excitement look of Naruto.
"But it's weird. The Holy Sword Excalibur is sealed at the bottom of the mid-air dungeon swarming with Tyrants. So why is the NPC revealed it as a quest reward?" asked Klein curiosly.
"That made sense. If NPC took them to the dungeon then I'd understand, but this..." said Silica while playing with Pina.
"It just my deduction, but there is something more in this quest then it seems" said Naruto with a narrowed eyes.
"Well, when we get there we will know" said Sinon not glaring at Naruto anymore, but still felt somewhat annoyed.
"Alright. All weapons are fully restored" said Liz and gave the weapons to them.
Klein looked at the party and said.
"Still our party is full of muscle head-"
He was interrupt by a cough behind. He looked back and saw Naruto coughing.
"Please, speak for yourself Klein" said Naruto.
"W-well, nearly everyone"
"Then just raised your magic skills" said Liz looking at Klein with apathetic eyes.
"No way, a samurai will never select any magic skills. That's against the samurai codex" said Klein and looked aside.
"Listen... In RPG, samurai also used magics as only the sword skills is not enough to fight bosses." said Liz
"I'd rather snap my katana and quit being a samurai then use magic" respond Klein stubbornly.
"But there was a time you used the flame sword skill. I think that it actually half magic" said Silica.
"Eh! Really?" asked Klein incredulously.
"Yeah, that's right. On May, the GM made all the high-level skills divided in magic classes of earth, fire, water, wind, dark, light and physical additionally" said Wendy flew to Naruto's head.
"Really?" asked Klein again.
Liz just looked evilly and said.
"What did you said just now? Rather snap your sword than use magic?"
Klein began to pale and holding for his sword protectively and back away from Liz little by little.
"Kirito..." muttered Klein.
Naruto looked at the pitiful figure of Klein and decided to say.
"But in sword skills you don't need incantations, so it not count as magic" said Naruto
Liz looked at Naruto then sigh and replied.
"If that's that then ok"
Klein mouthed 'thank you' to Naruto then said.
"Your wife is so scary. I don't even know how you still alive to this day"
Naruto just puffed his chest proudly and said
"Hmph, I am just amazing like that"
Kirito then turned to Naruto with a grin and said
"You understand why I want to obtain this sword so much do you?"
Naruto smirked back and said
"It's obviously you wanted to test yourself against me with the legendary weapon. You didn't challenge me before , because you don't have the weapon that was equal in strength with Kusanagi. So now it's the perfect timing, am right?"
Kirito just smirked back. While the girls just looked at the two of them. Then he turned to the party and said.
"I thank everyone for coming here so quickly. I will repay you guys later. But now let's do this"
"Yeah"

Tunnel to the underground

The party is running in the tunnel to underground that will reach Jötunheimr.
Lisbeth is complaining about the stairs.
"How many are stairs here actually? I am already so tired"
"I think it actually the size of the entire dungeon in New Aincrad. By the way where is Naruto-kun? I didn't see him anywhere" said Leafa as they continued to run.
"I think that jerk used the transportation magic and already ahead of us" said Liz with a tic mark on her forehead.
"Well, it's not actually his fault that he could transport a certain amount of people" said Kirito.
"Huh, he could at least takes me with him. That jerk, when I get my hands on him..." said Liz with a scary smirk. Everybody began to pity Naruto.
"To reach Jötunheimr by normal route is about two hours, and using this route takes only five minutes. Though Naruto reached there in 10 seconds" said Kirito and muttered the last part annoyed.
Sinon still felt annoyed that Naruto leave her here. He could actually takes her with him. She knew pretty well that he could transport 3 people at max. When she gets her hands on him he is gonna beg die forgiveness. There is a scary aura and scary smirk on both Liz and Sinon's face.
Klein seeing that whispered to Kirito.
"We better prepared a grave for Naruto. He was a great man after all"
Kirito nodded his head and felt pity for Naruto looking at the tigress ahead of him.
When they reached the entrance they sweat dropped seeing Naruto already there with Wendy on his head, slurping ramen bowls after bowls.
Naruto swallowed the ramen and decided to talk.
"Oh, you guys are here already. I thought it will take longer. But still you guys are such slowpoke"
Liz and Sinon glared daggers at him and shouted.
"Why the heck did you left us there? You could transport up to 3 people and decided to leave is there, you selfish bastard!"
Naruto raised his hands and tried to calm both girls down.
"N-now girls, what's wrong with walking once for a while huh? Besides its kit my fault you guys couldn't learn the transportation magic cause it's too complicated"
The girls just went to him and bopped his head then turned their head with a huff. Everybody looked at the science comically as Naruto being yelled at and bopped to the head by two girls.
"He is so whipped I couldn't even feel jealous of him anymore" said Klein looking at the scene.
After a while, the girls calm down though Sinon demand Naruto to piggyback her as its very cold out here. They looked up and saw a pyramid-like dungeon hang upside down in the mid-air. Naruto looked around and saw snow and ice everywhere.
"So this is Jötunheimr, one of the other world of ALO. I wonder how anybody can even live here" said Naruto.
Simon holds to Naruto in dear life as she felt really cold. Asuna seeing that practically everybody shivered in cold except Naruto and Kirito so she decided to cast a cold-resistance on them all.
"It's ok now. I've just cast a cold-resistance magic to everyone" said Asuna
Naruto looked from the corner of his eye s and said.
"It's not cold anymore Shino-chan. You can climb down from my back now if you want"
Sinon hold on to him tighter and muttered.
"Don't wanna"
Naruto just smiled softly at her and looked ahead.
Leafa looked at the two of them and felt a little jealous as she also want to piggyback by her Naruto-kun. She shook her head then whistle loudly to call her white strange friend.
Then they looked down and saw a half-elephant half-jellyfish creature flying up to them.
Naruto looked at the creature curiously and muttered.
"So this is Tonkii. It's the first time I am seeing this creature"
"I am gonna apply my mark to your wrist so that I will know the location. You go with them Shino-chan, if anything happened just channel magic to that mark and I will appear" said Naruto.
Sinon nodded her head and slowly climb down from his back though a little disappoint.
Then he looked up to his head and said.
"Do you want to ride that creature as well, Wendy-chan? Then you should go to Liz, Leafa-chan or Shino-chan. As I will just transport myself to where you guys are when reached the destination"
Wendy nodded her head and flew to Sinon's shoulder.
Then they all climb to Tonkii's head while Naruto just looked at them.
"It's a pity that Tonkii's limit is 7 people. I'd like for Naruto-kun to ride with is as well" said Leafa looking at Naruto.
"Don't worry about that Leafa-chan. I will still be with you guys in the dungeon after all" said Naruto smiled softly at her.
"Here we go, Naruto!" said Kirito.
Naruto nodded his head and waved to them.
And with that the party takes off to the entrance of the dungeon, left Naruto behind. Naruto decided to read some advance dark magic as he waited for them to arrive to the destination.

With the party

Lisbeth looked down and wondered.
"What will happen if we fall there, I wonder?"
"Well, I am sure that guy over there that tried to climb to the next level of Aincrad via outer pillars and fell will managed to explained to you the feeling" said Asuna and grinned at Kirito.
"Heh, but I think that the feline would be better at falling from high places" said Kirito and looked at Silica and Sinon with a grin.
"Just you try. Naruto will kick your ass for that" threatened Sinon pointing at Kirito. While Silica shook her head in negative rapidly.
Suddenly Tonkii flew down caused them to hold to him tightly to not fell off. They all screaming in fright, except Leafa who scream in excitement.
"Yahoo!"
When it was over the party sigh in relief. Leafa looked down and noticed something. She pointed down and said.
"Onii-chan, everyone look down"
They looked down and saw the people down there helping the four arms Tyrant to kill Tonkii's breathing.
"What's going on down there? Did someone tame the humanoid Tyrant?" wondered Asuna.
"That's impossible! The rate for taming a Tyrant is zero. Even for a Caith Sith will a full boost and special equipment" said Silica expertly.
"Which means they are taking advantage of that? When the four arms Tyrant attacked the elephant-jellyfish, they also attacking it too" said Klein.
And just that the jellyfish Tyrant was taken down. The Salamanders bellow decided to finish it off with a fire spell.
The jellyfish immediately was turn to a blue polygon. Tonkii roar loudly seeing his breathen was killed. And with that the humanoid Tyrant and the Salamanders party advanced forward. Then they saw more explosions down there.
"Maybe this is the same slaughtering quest that Asuna talked about" said Kirito
"So they used the humanoid Tyrant to speed up the process. It's a great idea, but at the same time awful. Cause it's felt really heartless" said Liz.
Suddenly, they sense a presence and turn back to see a giant lady appeared behind them. They all looked at her in wonder. The huge woman wore a blue dress and has long wavy blond hair. The woman began to talk.
"I am Urd, Queen of the Lake. You fairies who have bonded with my servant... My two younger sisters and I have a request for you. Please save this land from the frost giants"
Yui flew up to Kirito and said.
"Papa, this is an NPC. But something's strange. She isn't use the set response routines, like normal NPCs. She's connected to a language-engine module that's near the core program"
"In the words she's been turn to AI right?" asked Kirito.
"That's right, Papa"
Urd decided to tell them her story.
"Once, Jötunheimr was like Alfheim. It enjoyed the blessings of World Tree, Yggdrasil. And was covered in beautiful water and greenery. We, the hill giants, and our servants, the animals, lived in peace. Below Jötunheimr is the land of frost, Niflheim. One day, the king of frost giants, Thrym, decided to snuck in and invade Jötunheimr. He casted the Excalibur, the sword that which cut all trees and iron, into Urd's lake, at the centre of the world. The sword cut the deepest root of the World Tree, and when it did Jötunheimr was cut off the bounties with Yggdrasil. The result you can see right now"
"Thrym's frost giants attacked Jötunheimr, from Niflheim, building many castles and fortresses. Then capturing and imprisoning us, the hill giants. The pyramid that is hanging upside is actually their castle called Thrymheim. Now they rules this land. My sisters and I managed to escape to the bottom of a frozen lake, but we lack the power we once had. The frost giants were not satisfied, however, and they tried to kill all of our servants, the animals, that lived in this realm. And if they succeed then out power will vanish. Then they will invade the Alfheim and the other realm like with Jötunheimr"
"What? If that happened then the town of Arun will be destroyed as well" said Klein.
"King Thrym wanted to cover Alfheim in snow and rise to the top of the World Tree, Yggdrasil. Though he feared one person in the Alfheim the most. The person that can manipulate the darkness and shadow masterfully. The reason he wanted to reach the top is to obtain the golden apple that said to be there. Thrym and his generals have grown upset at their inability to slay our servants and have began to ask the help of the fairies. They feared that among the fairies there will be the person that they scared the most. Because of that he offered the Excalibur as a prize. And he wanted all my servants eliminated. Though that's a lie, king Thrym won't giving that sword to anyone. He wanted to use that sword to destroy the threat to his rulings. When Excalibur will be out of Theymheim. The bounties of Yggdrasil will return to this realm once again.
Kirito thought for a while and decided to ask.
"Did the person that king Thrym so afraid can travel at high distance through dark portals?"
"Yes, he after all is the only one in Alfheim hay capable of that. He is the hope of the realm and Alfheim. I know he is not with you right now. But please tell him that I will be very grateful if he saved this realm" said Urd.
"So the Excalibur being the quest reward is a lie after all. Naruto-kun was right there is more to this quest than it seems. But can it actually be done like that, the quest without a reward, when it declared that the reward was there" said Liz and asked Urd.
"He probably will give the false sword, Caliburn, which is the fake copy of Excalibur" said Urd.
"That's cheating! Is a king allowed to do that?" asked Leafa.
"That cheating is Thrym most potent weapon, but he made a mistake. He has send all the giants from the Thrymheim to assist the fairies in annihilating my servants. The castle defense is much weaker now. I believe that you fairies and the Dark Hero will save our realm" said Urd and then opened her palm and create a talisman in her hand.
"When this talisman turned dark means all my servants were slain and my powers gone. Fairies, infiltrate Thrymheim and draw the Excalibur from the keystone dias" said Urd.
Then the line appeared above her head that said' quest accepted'. Then she looked down at the fairies and said.
"I am counting on you, fairies, and the Dark Hero"

Time skip

The party continued to head to their destination.
"But who knows that Naruto-kun was actually chosen to save this realm. I didn't expect that" said Liz.
"And when we told him that his ego will skyrocket even more" said Sinon annoyed.
"We will clear this quest and obtain the Excalibur, that's the reason we came here after all. The defense is not so tough anymore and with Naruto I could say the quest won't be so hard" said Kirito.
"Ok, let's do this and received a place in the MMO Tomorow" said Klein in excitement.
With that they all cheered loudly.

With Naruto

Naruto was meditating for a while with closed eyes then he snapped his eyes open he felt their magic are near the entrance of the dungeon.
"Let's do this" said Naruto and chant am incantation to create a dark portal then step into it and disappeared in it.
