The next day, everyone heads to Yuna's first live concert.
Tails: Man, this is gonna be great!
Shino: Yuna's popularity sure is mind blowing.
Keiko: My throat still hurts from singing too much.
Karen: You were really great last night.
Asuna: Thank you for yesterday, Silica.
Keiko: Oh, you're welcome.
Andrew: Too bad Klein couldn't join.
Knuckles: Speaking of which, where are Sonic and Kirito?
Mighty: They said they needed to go to the bathroom.
It turns out they both went to the place where Eiji asked them to meet.
Kazuto: Ok, we're here.
Eiji: You both showed up on time.
Kazuto: You're going to give back Asuna's memories, even if I have to force you to.
Sonic: And it's not going to be pretty if we do.
Eiji: Hold on their, Mr. Black Swordsman and Sonic. You don't have to rush.
Kazuto: And are you Nautilus? The one player who couldn't overcome his fear of death and refused to fight in boss raids?
Eiji: That's not me anymore! It's Eiji now. I'm quite surprised you both know about me.
Sonic: We know someone who does.
Eiji: So seducing the Lightning Flash wasn't enough, and now you are both going after Yuna?
Sonic: What exactly are you plotting?
Eiji: Nevermind. Do you guys really think you can defeat me, the rank 2 player?
Sonic: Actually, you are pretty much outnumbered, even if one of us takes you on.
Eiji: We'll see about that.
They put their Augma's on.
Sonic, Kirito, and Eiji: Ordinal Scale, activate!
Sonic and Kirito both start fighting Eiji. Meanwhile, the concert begins and Yuna starts singing.
Yui: Wow!
Asuna: Here we go, Yui!
While the concert goes on, Shigemura watches from a high place.
Shigemura: I admit that I took advantage of my position as external board director of Argus to give Yuna the NerveGear with SAO. I wanted her to be happy, but it was my fault that she died, because of how blind I was.
Sonic and Kirito continue to fight Eiji. When Kirito swings his sword, Eiji grabs his wrist, and then Sonic uses his spindash, making him jump away.
Eiji: As expected as two who guided players to clear that death game.
Sonic: It's not like beating us will be that easy!
Eiji swings his sword again, letting out smoke to block their sight. They both watch their backs.
Eiji: In the end, people only remember those who fought on the front lines. Weaklings like me and Yuna are not remembered!
Kirito: Wait! You were with her in SAO?!
Eiji: I was!
Eiji appears next to them as they dodge his swing.
Eiji: I was even with her when she disappeared too! You have no idea how I have cursed myself! Even when she was in danger, I couldn't move even an inch!
Meanwhile, back in Shigemura's spot...
Shigemura: It was impossible to save or repair Yuna's brain that was damaged by the NerveGear. However, if I can get memories from other SAO players and combine those fragments, I can use Deep Learning to revive Yuna as an AI.
Back in the battle, Kirito and Sonic once again spot the object on Eiji's back.
Sonic: What is that? Is that how he gets power?
Kirito: An exoskeleton?
Once again back in Shigemura's spot, a ghost of Akihiko Kayaba stands next to him.
Shigemura: The numbers in Ordinal Scale are absolute. Whoever becomes number 1 is invincible. It was you who designed it that way, right Kayaba?
Kayaba: She must be una, which is Latin for one, right? In contrast to the Cardinal System which controlled Aincrad using cardinal numbers, the Ordinal System controls using only ordinal numbers. It seems that you have discovered the system I have discarded during early development of SAO, and now resurrected it in a new game. It's true that the man I was could have done the same thing. But you see, Professor Shigemura, the man I am now believes in the existence of power that can transcend the system itself.
Kayaba disappears. Back in the battle...
Eiji: Who cares if we take memories away from that death game anyway?!
Kirito grabs the exoskeleton and rips it out of Eiji.
Kirito: So this is the secret behind your power!
Sonic: Cheater!
Eiji: Why you!
As Eiji attacks, Sonic and Kirito deliver one last blow. Eiji's health goes down to zero.
Sonic: Unlike you, we aren't ones who deny their past selves just because they suffered one time.
Kirito: Tell us how to get Asuna's memories back!
Eiji starts laughing. Then, Yuna finishes her singing. The song ends and everyone starts cheering. There was a huge silence a while later.
Miyu: Is it over already?
Yuna: That was so fun.
Suddenly, the lights go out and Yuna disappears. Then, everyone's Augma's yellow lights shine, and a bunch of counting numbers appear on the monitor. A notification saying final event appears, and a bunch of SAO bosses appear around the dome.
Eiji: You're too late. Almost all of the SAO survivors are here. We will scan the brains of everyone who has come, and take their memories. Then, we will bring Yuna back to life.
Sonic and Kirito: What?!
Eiji: It's already started, and there's no stopping it now.
Sonic: I hear screaming up there.
Kirito: Let's go!
They both head up to the dome. Kirito calls Kikuoka.
Kikuoka: Here's what I learned from Karmus, the developers of the Augma. Right now, there are drones flying inside the stadium that are equipped with a wireless power feed function that can boost the output of the Augma's themselves.
Kirito: What does that mean?
Kikuoka: When they run that scan, it might be fatal. Even more than just memory loss.
Sonic: You don't mean!
Kikuoka: With a scan that powerful, it can kill nearly all of the people in there. We'll stop the professor, you guys tell everyone to take off their Augma's.
Kirito: But how?
Sonic: Let's get to the others first!
At the place where Asuna, Tails and everyone else is at.
Pitohui: This doesn't look good.
Mighty: What's going on? There are bosses from Aincrad appearing everywhere!
Yuuki: The doors are locked!
Sinon shoots down one a flying mantis boss, and then the Gleam Eyes appears right behind Asuna, Yui, Silica, and Yuuki. Asuna and Yui both feel afraid to fight.
Yuuki: We got this, Asuna.
Then, Sonic uses his spindash at the Gleam Eyes, knocking him away.
Sonic: Everybody alright?!
Kirito: Sorry we're late!
Asuna: Kirito!
Tails: Sonic!
LLENN: Where were you guys?!
Sonic: Long story!
