Sure enough, before Kirito and the others had walked for long, they saw that giant door over ten meters high.
However, there wasn't a single figure in front of the giant door.
"They... couldn't be that stupid, right?" Kaede tilted her head. "Did they really go in?"
"Although there are Teleport Crystals, looking at The Army's state, it's impossible for everyone to be equipped with one." As he spoke, Kirito's face turned solemn. "Hurry up."
"Mm." Several people nodded, and Kaede didn't object either.
Pushing open the giant door, shock appeared on their faces.
Because it was a one-sided situation; the people from The Army had already been scattered by the boss, looking completely devastated.
And right under the boss was the leader of The Army.
However, it looked like the situation wasn't good at all, because his HP had already hit rock bottom.
At this moment, that leader was holding a crystal in his hand, but for some reason, he didn't use it.
"Quick, use the Teleport Crystal!" Kirito roared over there.
The leader also heard Kirito's voice and turned his head. His face was filled with horror, his voice was trembling, and his eyes were shaking, pleading for help.
"The crystal... cannot be used."
The hand he stretched out toward Kirito only made it halfway.
A flash of a blade swept down.
Instantly, his entire being turned into shards of light and vanished.
Damn it! Kirito gritted his teeth, equipped his other one-handed sword, and charged forward.
Kirito! Asuna was startled and wanted to go over to help.
Mom, is Uncle going to be okay? Yui watched the flashing swords over there, fear flashing in her eyes; this was exactly why those people were afraid, and why she had suffered a mental breakdown.
He will be. Kaede had just finished speaking when she saw the boss room door open once again, and the person who walked in was a man wearing a red bandana.
Huh? That man? Kaede was stunned.
Yo, it's you, Kaede. You're here too? Klein also saw Kaede and couldn't help but ask.
But the next moment, Klein's gaze was drawn to the battle between Kirito and the boss; it was truly spectacular.
The flashing sword light, the radiance of the two swords alternating.
And the figure of the boss, slashing wildly at every moment.
That's... Kirito! Horror appeared in Klein's eyes. Kirito is soloing the boss? At that moment, a shocked Klein didn't even notice that Kirito was using two swords.
Mister, please look after Yui for me. Kaede had already arrived in front of Klein. After saying this, she turned and went to Asuna's side, looking at the battlefield with a grave expression.
However, she had to go.
Because Kirito's HP was dropping faster than the boss's HP!
If things continued this way, something would definitely happen to Kirito. Kaede did not want to see that happen, so the next moment, she dashed out.
Asuna also charged out at the same time.
The battle between Kirito and the boss was almost dazzling; if an average player saw this scene, they would probably be scared stiff, let alone intervene.
However, that did not include Kaede and Asuna.
But both of them knew that they absolutely could not disturb Kirito at this moment, because one slip could mean life-threatening danger.
In the end, it was Kaede who joined the fray first.
Kaede moved like a ghost, silently appearing behind the boss, her body constantly dodging the scattered sword lights, and then she slashed hard at the boss with her blade.
At this moment, Kirito also noticed Kaede and Asuna and breathed a sigh of relief. It looked like if he had continued on his own, he would certainly have lost, but he couldn't afford to lose—no, it should be said that no one could afford to lose.
Because you only have one life.
Kirito also slowed down his attack speed at this time, focusing most of his attention on dodging.
Before long, the boss's gaze shifted to Kaede and Asuna, and taking advantage of this gap, Kirito was finally able to use a potion.
However, the next moment, Kirito, who had intended to rejoin the fight, stopped in his tracks. Watching the situation in the arena, he suddenly felt that he didn't seem to need to step back in.
Because the situation in the arena had stabilized.
This is!
Not only Kirito, but Klein and the people he brought with him all widened their eyes.
Kaede and Asuna were seen switching back and forth at super high speeds, one in front and one behind, without saying a single word.
Yet, despite this, their coordination never had a single flaw, and the result of that perfection was that the boss had barely touched this pair of sisters, even though it was an agility-type boss.
Seeing that the boss still had about half a bar of HP left, Kaede and Asuna nodded simultaneously and moved to either side of the boss.
Although that was theoretically the safest position, it required a significant amount of stamina, and if they made a mistake, both of them would be finished.
Next, one strike would decide the outcome.
Kirito had a feeling that the coming moment would be one to witness glory.
Kaede and Asuna's weapons simultaneously began to flash, glowing with light.
Everyone knew this was what happened when a skill was being activated.
The next moment, the boss's attack arrived.
At this moment, a smile played on Kaede's lips. Her figure flashed, leaving an afterimage right where she had been; her ultimate skill was complete, and the same was true for Asuna on the other side.
Now, it was time for the show.
Asuna's sword light was red, while Kaede's blade light was blue.
At this very moment, one red and one blue, two brilliant beams of light exploded with dazzling radiance directly in front of and behind the boss.
This is... an Ultimate! Kirito understood; this was an Ultimate, an ultimate skill on the same level as his Starburst Stream.
And it's even fused! This was the fact that shocked Kirito the most. Kirito knew that Starburst Stream was not his final ultimate, but even so, he was certain that Starburst Stream was one of the top-tier ultimates in SAO, and it was definitely stronger than what Kaede and Asuna were performing.
However, Kirito lost his confidence; even his final ultimate, The Eclipse, might not necessarily beat them.
This was no longer a case of one plus one equals two; the result of the fusion was terrifying.
The red sword light and the blue blade light had fused together. Under this barrage of swords and blades, the boss's resistance was like a light drizzle, unable to shake this world of flashing steel in the slightest.
At this moment, the protagonists were Kaede and Asuna, who were still swinging their blades.
Perhaps only the two of them could achieve this, Kirito muttered to himself. The fusion of this ultimate was truly astonishing. Perhaps only their inseparable bond could achieve such a level...
Papa, Mama... Stars appeared in Yui's eyes as she watched Kaede and Asuna there, her heart filled with excitement. These were her parents, the parents she should be proud of.
Klein was already stunned—no, everyone was stunned, and naturally, no one noticed how Yui addressed Kaede and Asuna.
Finally, the ultimate ended, and along with it, the boss's life. From this point on, the 74th floor of SAO had been cleared!
The figures revealed beneath the light were two identical girls.
The two girls stood back-to-back in the center of the stage, welcoming the cheers of those around them and bearing the admiring gazes of the crowd.
Adoration was the most genuine emotion everyone around felt for the two girls in the center at this very moment!
Proud, magnificent!
