ALO
New Ancraid
The square in front of Haou Castle.

Naruto looked at Kirito through his fox mask. While Kirito is looking around him, as he was surrounded by Naruto's Kumenjū. His Alpha-Stigma is blazing brightly. He tried to analyze the magic that Naruto has casted.

Kirito took a deep breath then began to chant incantation. The smoke covered his body and when it was cleared, in Kirito's face was the fearsome figure if Fatal Scythe in front of Naruto, towering him.

"Heh, so you decided to use Reality Illusion after all. But even if you are more powerful it that form didn't mean you could win this fight. Charge!" said Naruto looking at the huge figure of Fatal Scythe in front of him then ordered for his mask beasts to attack.

The nine mask figures all charges at Kirito. The mask tiger jumped at Fatal Scythe and tried to tear him apart with its claws. The mask bird pieces continuously at the Fatal Scythe, also flying around him. The mask dragon roared loudly and from its mouth an energy ball flew towards Fatal Scythe.

But Fatal Scythe swings his huge scythe and blew the energy ball away.

The rest of the masked figures tried to damage Fatal Scythe, as much as they could. Fatal Scythe has enough and create a shock wave from its body caused an explosion and all the masked beasts was dispersed.

Suddenly behind Fatal Scythe, Naruto appeared in mid air with Dairasenringu in his hand and was about to slammed into him.

Kirito deactivated his spell and returned back to normal just in time to avoid the Dairasenringu. Then he raised his hand up and began to chant incantation.

"Apes Igniferae!"

From his hand a dozens of flame bees appeared and flew towards Naruto.

With the party

They looked wide eyes, except Leafa as they saw Kirito used a spell.

"With Alpha-Stigma activated Onii-chan can used any spells now in the interval of 5 minutes. Those spells I guess are the spells that Onii-chan had prepared in order to face Naruto-kun" explained Leafa looking at the battle.

"So does Kirito-kun has a chance to win?" asked Asuna.

"That we can't tell. Naruto is the master of dark magic after all" said Sinon.

"The battle is so far even. But I believe on Kirito. He will win!" said Klein with confidence.

"Well, those two always want to test themselves against each other. And now that they finally have a chance, they will try their best to defeat each other" said Agil looking back to the battle.

"Naruto-kun still seems to be holding back... I-I don't know why I feel that but I could feel it" said Liz fidgeting.

Naruto vs Kirito.

Naruto saw the flame bees charged at him and activated his teleportation magic to teleport them away.

"Not bad Kirito. But before I forgot, what was that skill that destroyed Yata no Kagami. It certainly is not a system's skill. So what is it?" asked Naruto curiously.

"Yes, that's right. It's not a system skill. It's called Skill Fusion. By activating different skills at the same time and unleashing them. I could fuse both skills into a much powerful one. Though I could only use it once in a battle. But it was worth it. Because I successfully destroyed the Yata no Kagami" explained Kirito.

Naruto whistled at this discovery impressed, though it's a shame that the skill could execute only once in a battle. Then Naruto recalled something and snapped his fingers.

"I forgot to mention something special about this bonus quest"

"And what is so special about this quest?"

"If the leader of the party died, then the quest is automatically failed. In other words, if you died then the whole party failed the mission" explained Naruto with a smug face.

Kirito widen his eyes at that then smirked.
"Interesting. Really interesting. But what if I told the girls to charge at you now. Do you really think you will win?"

"It doesn't matter. But you won't do that after all, you came here to test your limit against me" said Naruto smirking.

Kirito sighed and said.
"Heh, you know me too well. But I will try my best to defeat you. Here I go, Naruto"

With he charged at Naruto and began to chant incantation.

"Flagrantia Rubicans"

The huge fire blast flew from Kirito's hand at Naruto.

Naruto eyes turned serious and replied.

"Lorica Umbrae"

Before the fire blast hit him Naruto was covered by the cloak made of shadow that protected him.
Kirito activated his wings and flew up then continued to chant incantation.

"Sagitta Magica, Ignis Interitum"

A barrage flame arrows flew from Kirito's hand at Naruto with great speed.
Naruto countered with his spell

"Tenebris Rugiet"

Out from Naruto's body an aura that looks like a demon head appeared, roared and deflect all the flame arrows.

Kirito covered his face with his hands as the wind blew harshly from the roar. Kirito flew up high in the air then raised his hands to the sky and shouted.

"Ignis Infinitum"

What happened next cause Naruto to widen his eyes in fright. From the sky hundreds of fire beams flew at him. Naruto grouted his teeth as his transportation magic still not recovered.
The fire beams all flew at Naruto with great speed and prepared to annihilate him.

With the party

Everybody looked shocked at what Kirito has chant.

"With this Kirito will definitely win. Naruto couldn't do anything but watch as the fire beams flew towards him. It's over! We have won" said Klein in excitement.

"Not yet" said Sinon looking at Naruto's expression.

"Huh? What are you talking about? There's no way Naruto could counter a spell like this" retort Klein narrowing his eye brows.

"Look at Naruto's face. Does it look like the face of the person that accepted defeat?" asked Sinon smirking.

They all looked at Naruto and saw he is smiling.

"W-why is he smiling? Isn't he in a tight rope now?" asked Silica not understands.

"It's simple. Naruto is enjoying this fight. He is glad that Kirito-kun has pushed himself this hard to defeat him" answered Asuna smiling.

Naruto vs Kirito.

Naruto took a deep breath then began to chant a new incantation.

"Reflexio Est Niger!"

With that a huge black mirror appeared before him and deflect all the fire beams back to the sky.
Naruto after chanting the incantation panted really heavy. Kirito looked wide eyes at what Naruto have done. Besides the summoning of Four Sacred Beasts, Ignis Infinitum was his strongest spell and even it didn't enough to defeat Naruto. Kirito using this moment when Naruto was exhausted decided to charge at him with Excalibur in hand.

Naruto panted heavily after his spell then he looked up and saw Kirito is charging at him with Excalibur in hand. He prepared Ame no Murakumo to deflect the strike that will come.

Kirito activated the flame sword skill and roared then began to assault Naruto, forced him in defense.
Naruto gritted his teeth as he was still exhausted from the grand spell that he just casted. Then he recalled one spell that will turn this situation in his favor.

"Gravitas Ligaveris"

With that Kirito suddenly felt his body became more heavily. He felt that the gravity began to push him to the ground. Finally he couldn't withstand the weight of the gravity that is pushing him and slammed on the stomach to the ground.

With the party.

The party was shocked that Naruto managed to defect such a spell and once more impressed at his ability. They saw that after casting such grand spell, Naruto began to pant heavily. Then Kirito rushed at Naruto with Excalibur in hand with intention to deliver a strike to Naruto. Then the saw Naruto withstand the strike and deflecting it with his Ame no Murakumo.

Kirito continued to assault Naruto while he still not recovered. They all thought that Naruto was cornered and Kirito was about to win. But suddenly Naruto chant some incantation that caused Kirito to fall on his stomach.

"Kirito-kun" shouted Asuna worriedly.

"It's bad. Naruto-kun's spell that has been chant was a gravity spell. Now Onii-chan won't be able to stand up. Naruto-kun has the advantage now" said Leafa.

"Kuso, when we are about to think that Kirito had won, Naruto pulled a stunt like this" said Klein irritated and slammed his knuckle to his palm.

"It's not over yet. There is no way Kiriro is going to let this end like this. I am sure he still has a trump card in his sleeve" stated Agil with narrowed eyes.

"Show me your determination, Kirito" said Sinon looking at the lying figure of Kirito.

Naruto vs Kirito.

Naruto stood towering above Kirito looked down while panting and said.

"It's over Kirito. You have done a good job to push me this far. But it's over now. I won. You are just as exhausted as me, while being crushed by the gravity and couldn't stand up"

Kirito gritted his teeth and thought.

'Kuso, I can't let things end like this. I won't lose! It seems I have no other choice but to summon them then'

Naruto raised his Ame no Murakumo and was about to finished Kirito off. Kirito looked up in determination at Naruto and began to chant.

"The immortal bird that guards the South. Come to me and annihilate my enemy. Invoke! Suzaku"

The portal appeared before Naruto that caused him to jump backwards. From the portal a huge phoenix appeared and screeched loudly that cause wind to blow harshly and Naruto to cover his ears.

"Kuso, he finally summons it. One of the Four Sacred Beast, the immortal bird, Suzaku" muttered Naruto sweating nervously looking at the legendary being.

With the party

They saw that Naruto was about to finish Kirito off and shouted our his name. But suddenly a portal appeared before Kirito and out from it a huge phoenix appeared magically protected Kirito from Naruto's assault.

"W-what the heck is that? Where did that huge Phoenix come from? Did Kirito was the one summoned him?" asked Klein in shock and awe.

"That's right, Klein-san. This is one of the Four Sacred Beast, Suzaku. This is one of Onii-Chana's strongest spells. And if he summoned Suzaku then the other will be summon soon as well. This is Onii-chan's last trump card" explained Leafa also in awe at the sight of the legendary being in front of her. Even if she already saw it, but it still manage to impress her even now.

"Wow, I actually read about the legend of Four Sacred Beasts. But now that seeing with my own eyes, makes me feel even more excite" said Silica.

"Alright, Kirito. It's time to take Naruto down" shouted Klein with glee.

Sinon and Liz turned to Naruto's side and watch his action carefully and silently. They want to see how Naruto will fight Suzaku.

Naruto vs Kirito.

Kirito used all his will and stood up then he summoned the rest of the Sacred Beasts and have them surrounded Naruto.

"It's really over now, Naruto. With all the Sacred Beasts summoned you don't have a chance to win any more. It's my victory, Naruto" stated Kirito looking down at Naruto, from the back of Byakko.

Naruto looked around him and saw he was surrounded by all Sacred Beasts. The sight was very intimidating. The normal person would have run away from the battle. But Naruto is different he has gone through things far worst then this.

"It's true that I maybe not be able to win. But even something like this won't let me back down. If you unleashed everything you've got. Now I will do the same"

With Naruto closed his eyes and began to chant.

"Oh, the ruler of serpents. The eight-head legendary evil god that destroy everything in its path. Appear before me and strikes the fear in my enemy's heart. Invoke! Yamata no Orochi"

Beneath Naruto a portal appeared. And from it an eight-head gigantic serpent slowly appeared. Eight of its head looked at the Four Sacred Beast and hiss threatingly at them.

"Let's settle things once and for all Kirito. This is the final battle!" Naruto shouted.

"Yeah, it's time we determined who is the winner of this intense battle!" shouted Kirito.

With that the Four Sacred Beasts charged at the Yamata no Orochi and the final battle has began

A/N: Next chapter will be the climax of the battle between Kirito and Naruto. Who will win that harsh battle? That will be revealed in the next chapter. After that comes Mother's Rosario arc, where Yuuki will challenge Asuna and Naruto to a duel.
