While the battle inside the dome goes on, Kikuoka tries to look for a way inside.
Kikuoka: Darn, it's all locked. We'll just have to leave the entire venue to Sonic and Kirito. We gotta hurry!
Kikuoka and his agents start heading to where Shigemura is. Shigemura looks behind him and see's Yuna.
Shigemura: Yuna?
Yuna: Dad, you have to stop this now.
Shigemura: But we're almost finished.
Yuna: I don't care.
Shigemura: You are still at the level of AI where your self-preservation program is making you talk like this. Just wait patiently.
Yuna: But Dad...
Shigemura: I'm having an AI protocol running a final test. It's her last test, and she did a fine job.
Yuna: You can't do this! If you run that scan, it may not just take away their memories, but also kill them!
Shigemura: Quiet! Now!
Shigemura starts thinking of the time he first gave his daughter the NerveGear.
Shigemura: If I bring you back to life, I swear I will sell my soul to the devil! Even if that means I follow the same path as Kayaba. I just want to get that moment back.
Meanwhile, Kikuoka and his agents arrive at the door where Shigemura is at. One of the agents tries to get in but it's locked.
Kikuoka: Give me that.
Kikuoka grabs a gun from the agents pocket and shoots the lock. The door opens and everyone heads inside. They don't see Shigemura so far.
Kikuoka: He's not making this easy, isn't he? Find out where that camera is connected.
Shigemura: I guess we're even now, Kikuoka.
Shigemura gets a call from Eiji.
Eiji: I just lost to Kirito and Sonic. All that's left now is to do the simultaneous scan, right? We can finally bring Yuna back.
Shigemura: You still have one more task though.
Eiji: What?
Shigemura: You need to hand over your memories too. You were with Yuna the longest in SAO, right?
A dragon boss appears in front of Eiji.
Eiji: No!
Shigemura: Sorry, but I don't have anymore use for you.
Eiji: You liar! You said I could be with Yuna forever!
Shigemura: So long, Eiji.
Eiji: NOOOOO!
The boss monster defeats Eiji. Meanwhile, everybody finishes taking down the Gleam Eyes.
Strea: There's too many of them!
Amy: How long is this gonna last?
Sonic: No idea.
Then, the Fatal Scythe appears, and uses a slash with his scythe. Then, Yuna appears and blocks the attack with a shield.
Kirito: Yuna!
LLENN: What?
Sonic: What are you doing here?
Yuna: Listen, I need your help, Kirito, Sonic! Soon everyone here will be in danger! As soon as those numbers on the monitor goes up to 10,000, a high output scan will begin, which will damage their brain!
Tails: High output scan?!
LLENN: No way!
Sonic: Everybody take off your Augma's!
Kirito: Hurry! It's dangerous!
So far, nobody in the surrounding area listens.
Knuckles: It's no use! They can't hear us!
Yuna: The reason my dad made all of these event bosses appear was to make sure that everybody would fight them here!
Sonic: What do we do?!
Yuna: That place we were in yesterday was Aincrad's 100th floor!
Kirito: 100th floor?!
Sonic: I knew it!
Yuna: You have to defeat the boss! I'm sure this entire mess will stop once you do! I'm unlocking the full-dive function on the Augma right now! Sit down somewhere!
Tails: The Augma has a full-dive function?!
Yuna: The Augma is another version of the NerveGear, but with limited functions. You gotta hurry, now!
Sonic: We're on it!
LLENN: We're helping too.
Strea: Yeah.
Silica: Count me in.
Mighty: Don't forget about us.
Knuckles: Yeah.
Ray: We are going to win this.
Agil: That last boss is going down.
Yuuki: And I can tell this is gonna be a tough one.
Kirito: Thanks you guys.
Sinon: Let's do this.
Rain: Seven, Snow, are you two ready?
Snow: Yeah. I am.
Seven: He's going down.
Tails: I'll stay here and protect Asuna and Yui.
Kirito: Thanks Tails.
Asuna: Kirito...
Yui: Daddy?
Kirito: It's ok. I will come back home soon. I will save everyone else too. Just trust me and wait a little longer.
Kirito hands Asuna a necklace with a gem looking just like Yui's heart from SAO.
Asuna: Oh Kirito.
Kirito: I will keep my promise when we get back.
Asuna: I believe in you.
Yui: You can win, Daddy!
Kirito: Thanks you two.
Tails: Good luck Sonic.
Sonic: Thanks buddy. Here goes everyone.
Everybody sits down and closes their eyes.
Everyone: Link start!
Then, everyone except Asuna, Yui, and Tails dive into the place where the final boss of SAO appears in. Aincrad's 100th Floor, the Ruby Palace.
LLENN: This is Aincrad's last floor?
Lisbeth: The Ruby Palace.
Agil: I never thought we would ever come here after two years.
Ray: Look!
Everybody looks and see's the boss.
Knuckles: Is that the last boss?!
Pitohui: It's ginormous!
Rain: I've never seen a boss like this before!
Then, the boss attacks Agil with its spear.
Kirito: Agil!
Agil blocks the spear with his axe. The name of the boss shows as An Incarnation of the Radius.
Agil: This is a big one alright!
Sonic: Let's go!
The monster takes its sword and slashes Agil down on the ground.
Agil: Crud!
Then, the monster fires some elemental blasts. Sonic, LLENN, Yuuki, and Kirito dodge it, but the attack sends Knuckles, Mighty, Ray, Pitohui, Fukaziroh, Strea, Rain, Seven, Snow, Lisbeth, and Silica flying back. Kirito attacks the barrier with his sword, and Sonic uses his spindash, and LLENN shoots her assault rifle. Then, the monster shoots a blast, sending Kirito, Yuuki, and Sonic flying back.
Yuuki: This is one hard boss!
Just as the boss attacks them again, Sinon, Pitohui, LLENN, and Fukaziroh shoot their guns at it. Then the enemy shoots a blast at them. Agil, Strea, Knuckles, Mighty, and Ray charge at the boss. They quickly react to the spear attack.
Strea: Switch!
Sonic, Kirito, Yuuki, and Rain charge in to attack.
Kirito: Switch!
Seven, Snow, Lisbeth, Silica, LLENN, and Fukaziroh attack, and the barrier gets broken, knocking the boss back a little.
Knuckles: It's broken!
Then, the boss makes a tree grow on top of itself, and a water drop falls onto it. The boss heals itself.
Yuuki: You've gotta be kidding me!
LLENN: A boss that heals itself?!
Mighty: How are we supposed to beat it?!
The enemy then slams its spear on the ground and some giant tree roots attack them. Meanwhile in the real world, the scan numbers are now going over 9,000, and Tails protects Asuna and Yui from the other bosses. Asuna and Yui both hold onto each other in fear.
Yuna: I'm so sorry, Asuna. It's my fault you have lost your memories, because I was a player who died in Aincrad. My dad is trying to take memories of every SAO survivor in order to revive me, by running a high-output scan. If that happens, it might lead to irreparable damage to the brain. And even kill them.
Asuna: No way!
Asuna tries to reach for Kirito's Augma, but Tails stops her.
Tails: Don't!
Asuna: If I take it off, I can save Kirito, but then what about everyone else?
Asuna then starts thinking about SAO. She starts to calm down a little bit.
Asuna: Yuna, I know why you died in SAO. You left the safe zone so that you could fight a monster to clear a floor.
Yuna's eyes widen when she says that.
Asuna: I'm going to do the same thing. Tails, I'm going to help the others.
Tails: Alright Asuna. I'll catch up soon.
Yui: I want to go too.
Asuna: It's too dangerous Yui.
Yui: I don't care! I want to go! I'm going!
Asuna: Are you sure about this? We don't know what the boss is.
Yui: I'm not scared.
Asuna: Ok then.
Asuna and Yui both sit down. They both hold hands, and Yui holds her fathers hand.
Asuna and Yui: Link start!
At the boss fight on the 100th floor, everyone except Sonic, Ray, Silica, Pitohui, Kirito and Snow get stuck.
Mighty: I can't get out! I'm stuck!
Yuuki: Same here!
The ground below Ray, Silica, Pitohui, and Snow rise. They both start getting crushed.
Sonic: Ray!
Kirito: Silica!
When Sonic and Kirito attack, the boss grabs them and gets ready to fire a blast.
Agil: Kirito!
Lisbeth: Silica!
Mighty: Ray!
Knuckles: Sonic!
LLENN: Pito, no!
Silica: No! Stop!
Sinon: I can't reach my sniper rifle!
Kirito: This is bad!
Then, a big blast comes down on the ground and hits the boss really hard, and everybody breaks free. Silica falls starts falling, and she see's Asuna and Yui. She starts crying.
Silica: Asuna!
Asuna: Hang on Silica!
Mighty: I got you Ray!
Fukaziroh: Hang on Pito!
Mighty grabs Ray, Fukaziroh grabs Pitohui, and Sonic grabs Yui from a fall.
Silica: I'm so sorry! It's my fault that this happened!
Asuna: Stop apologizing. It's ok now.
Kirito: Asuna!
Everybody meets with Asuna.
Asuna: I'm sorry I'm late everyone.
Agil: Alright!
Sonic: Glad you came, Asuna. You too, Yui.
Kirito: Are you feeling alright?
Asuna: Yeah. I'm not afraid anymore, so I'm going to fight.
Kirito: That's good.
Sinon starts shooting the boss again with her sniper rifle. Then as soon as the boss was getting ready for another attack, a big magic blasts hits it.
Sonic: Huh?
LLENN: Where did that blast come from?
Everybody looks behind and they see Leafa and Tails flying down together, along with a Spriggan girl with a dagger.
Leafa: Hey Kazuto! Sorry I'm late! This Spriggan right here is Philia by the way.
Philia: Nice to meet you guys!
Tails: Sonic! Kirito! I brought everyone here!
Eugene: This looks like an awesome challenge.
Sakuya: It's not a game though.
Klein: Alright! We're invincible in VR!
Siune: Yuuki!
Yuuki: You guys came!
Klein slashes his sword at the boss, and then Sakuya and Alicia shoot a magic blast. Then a bunch of machine guns get shot at the boss. The bullets came from Dyne, Itsuki, Zeliska, Kureha, M, Behemoth, Ginrou, and Yamikaze.
Kureha: This may be the toughest boss I have ever fought!
Itsuki: No doubt!
Zeliska: We got this!
Dyne: She's a big one!
Sonic: Alright! Now we're talking!
Kirito: They're here?
M: Are you alright LLENN?
LLENN: Thanks M!
Sakuya: There's not much time left!
Klein: We're attacking all at once!
Tails: You guys will need these!
Tails raises a yellow light, and then Kirito, Asuna, Silica, Lisbeth, Strea, and Agil change into their old SAO avatars. Then, Sinon, LLENN, Fukaziroh, and Pitohui change into their GGO avatars, and then Yuuki, Rain, Seven, Yui, and Snow change into their ALO avatars.
Sonic: Woah!
Kirito: These are our SAO avatars.
Pina flies down to Silica.
Silica: Pina! You're here!
Ray: LLENN? Fuka? You are both really short, and Pito is really tall!
LLENN: Wow! You're so cute Yui! With those fluffy ears, and I just noticed that you're smaller than me and Fuka.
Yui: Meow!
Tails: I've just reopened the SAO data storage for you guys. I've also given Sinon, Yuuki, and the others their avatars from ALO and GGO.
Amy: That's great!
Kirito: This will be easy. Maybe.
Tails: And Sonic, I think you'll need these!
Tails tosses down to Sonic, the seven chaos emeralds.
Sonic: The chaos emeralds!
Tails: You ready?!
Sonic: Yeah! Alright everyone, this is where the real fun begins!
Sonic uses the seven emeralds to turn into Super Sonic. Kirito takes out his two swords, the Elucidator and Dark Repulser.
LLENN: Let's go my Darling P!
My Darling P: I'm right here with you, LLENN!
Kirito: Let's go!
Everybody starts attacking. Asuna and Yui use shooting star, Kirito uses Final Revolution, Sinon shoots with her sniper rifle, and then LLENN attacks with her P90. And then a bunch of grenades get shot from Fukaziroh. Mighty, Ray, and Tails all use their spindash, while Knuckles starts punching, and then Super Sonic uses his spindash to knock the boss back really hard.
Rain: Man, that packed a huge punch!
Eugene: It's not over yet!
Eugene, Leafa, Philia, Jun, and Nori attack. They dodge the enemies blasts. The ground below Dyne, Kureha, and Ginrou rise, but they were able to evade the blast and they drop down to the ground.
Zeliska: You alright Kureha?
Kureha: Yeah.
Lisbeth Silica, Snow, Seven, Strea, and Agil then do a massive power attack on the boss. Then, the enemy starts using its healing move.
Asuna: Stop that move!
They all shoot their guns and magic blasts at the enemy, and the healing spell gets cancelled.
Super Sonic: Let's finish this off!
Yuuki: We're gonna win this!
Super Sonic, Kirito, Asuna, Yui, Yuuki, Rain, and LLENN start charging ahead. The boss starts attacking them, and then Leafa and Sinon shoot the vines to counter. Sinon somehow misses.
Sinon: Darn it!
Kirito, Asuna, and Yuuki cut through the vines. When the enemy attacks with her spear, Kirito reacts to it.
Kirito: Switch!
Rain: Here we go!
Rain uses her original sword skill, Thousand Sword Rain. Then, LLENN charges up her P90 for a very powerful blast, and Asuna, Yui, and Yuuki both use their OSS, Mother's Rosario. Then, Kirito uses Starburst Stream. Finally, Super Sonic delivers one last powerful blow with Kirito. The boss monster gets defeated and disappears.
