In Planetune:
Rei begins to laugh as she grows wings.
Rei: Hehehe! Hahaha! That's one down!
Sonic: ...
Nepgear: Sonic-kun!
Compa checks up on Sonic.
Compa: This is bad. He's badly hurt.
IF: That blast must've gotten him bad.
Rei: Now then. How about another!
Rei charges up the beam again as it aims at them.
Girls: Lady Neptune!
Lady: Oh no!
Lady2: We're done for!
Lady3: I don't wanna die!
Nepgear: We'll be fine, everyone. Calm down. I'm sure sis will save us!
Lady: But she's been defeated!
Lady2: Even Sonic!
Lady3: It's all over for us!
Nepgear then goes to transform.
IF: Nepgear!
Histoire: You mustn't! We still don't have enough Share Energy.
Nepgear stops her transformation as she falls down to her knees and begins to tear up.
Noire: What's with the gloomy look?
Nepgear: Huh?
Noire: Haaa!
Noire attacks the wing as Neptune was falling.

Rei: Huh?
Vert: Rainy Ratnapura!
Vert uses her special attack, but she uses her wings to block it.

Noire catches Neptune from the sky.
Noire: Is this your so-called event? A bit tacky, don't you think?
Neptune: Noire! Vert too! You came?
Vert: I simply came here as 5pb's chauffeur.
Uni carries 5pb in the sky.
5pb: Hi!
Uni: Sorry to keep you waiting, Nepgear.
Nepgear: Uni! 5pb!
5pb: Thank you, Uni.
Uni: No problem. Huh?
Uni sees Sonic laying on the floor.
Uni: Sonic?
Nepgear: He's been hurt badly.
Uni: I see... I'll go join sis and the other, then.
Nepgear: Okay! Please do my part as well.
Lady: Is that 5pb?
Lady2: What's she doing here?
5pb: Listen, everyone! There's nothing to worry about. Let's believe in our goddesses!
Vert: My, she certainly did dredge up something rather absurd. Who is she?
Neptune: She's apparently the CPU of Tari, the superpower of old. But I can't imagine how a nation that collapsed so long ago got its hands on so much Share Energy.
Noire: Where's Sonic?
Neptune: He's been badly hurt. He's with Nepgear and the others.
Noire: I see. Look there. Eden was using a similar device. It's a machine that creates Share Energy.
Vert: In that case, we should start destroying it, should we not?
The three goddesses draws their weapons as they go towards Rei. Rei uses her weapon and shocks both Neptune and Noire.
Neptune, Noire: Guahh!
Vert: Haaa!
Rei tries to shock Vert, but she dodges it as Vert throws her lance towards the machine, but Rei shocks her weapon as it vanishes.
Uni: I'll take care of the woman.
Uni shoots at Rei, but she blocks it with her wings.
Rei: I have to say, four-on-one's a bit annoying.
Rei uses the machine to take both Lastation and Leanbox's Share Energy as they couldn't move.
Uni: My powers are draining away...
Vert: What's... going on?
Neptune: What did you do?
Noire: I'm losing my Share Energy!
Neptune: Wait, is that thing... a device that steals Shares?!
Rei: Exactly. Oh, the laser should be fully charged by now. Can I push the big red button, then?
Neptune: No, don't!
Rei: I'm still gonna do it, though. Fire!
Neptune: No!
The laser fires as it goes straight to where the citizens are.
Rom, Ram: Ice Sanctuary!
Rom and Ram creates a ice barrier deflecting the laser.

Rei: What?
An axe gets thrown as it breaks the machine making the goddesses move again.

Blanc: Attack the laser from below, and she can't hit you with her lighting. Right?
Neptune: Blanc!
Nepgear: Rom! Ram!
Ram: We did it, Rom! We're the best!
Rom: Yeah, Ram. The best! Huh?
Ram: Big bro!
Compa: He's hurt. He just need some rest.
The Share Energy comes back to them as Nepgear feels her energy coming back to her.
Nepgear: I can feel the Share Energy. Histy.
Histoire: Go ahead. We'll watch Sonic.
Neptune: Thanks, Blanc.
Blanc: I calmed down and thought about it. I realized that everything made sense if Eden's machine could steal Shares.
Noire: Way to go, Blanc. But you went and kept the best part all to yourself.
Vert: No fair.
Nepgear: Sis!
Nepgear goes to where everyone is.
Rei: Heh, I'll just blow you all away!
As Rei charges up a blast from her hand, a sudden blast hits hers as it disappears.
Rei: What?!
Everyone: Huh?!
IF: What was that?
Histoire: Look!

[There should be a GIF or video here. Update the app now to see it.]

They all looked as Sonic was covered with Share Energy and blue aura.

Histoire: That's what Sonic-san said before. When he was fighting, Share Energy went through him.
Sonic gets back up as big blue aura surrounds him.
Sonic: (This form... it's just like from when I went to Maple's world.)
Everyone: Huh?
Nepgear: It's...!
Neptune: Sonic-kun!
Everyone: Sonic!
Sonic flies up to the others.
Sonic: Hey, guys. Sorry I'm late.
Neptune: What is that form?
Sonic: It happened before when I was in another world. But I feel Share Energy around me.
Nepgear: That's what you said before.
Sonic: Yeah.
Noire: You came just in time.
Blanc: I'm sorry about what happened before.
Sonic: It's fine.
Rom, Ram: Big bro!
Sonic: Hey, you two.
Vert: Seems you now woke up.
Sonic: Yeah.
Rei: You...!
Sonic: Now then... Let's say we finish her off!

Everyone: Yeah!
Sonic and the others flies towards Rei as she tries to shock them, but they dodged it. Nepgear, and Uni shoots at Rei, but she uses her wings to block it.
Vert: Rainy Ratnapura!
Vert uses her special attack, but Rei blocks it as she tries to shock Vert, but she dodges it.
Noire: Haaa!
Noire and Rei clash their weapons as Rei pushes her back.
Sonic, Neptune: Haaa!
Sonic throws two shurikens and Neptune goes to attack, but she clashes with the shurikens and Neptune. Rei pushes her back as Sonic goes in.
Sonic's fist starts to glow as Share Energy was surrounding his fists.
Sonic: Super Aura Punch!
Rei uses her wing to block Sonic's punch, but was too powerful as it breaks one of her wings.
Rei: How dare you!
Rei uses her vines and throws Sonic down.
Sonic: Gh...!
Rom, Ram: Ice Sanctuary!
Rom and Ram creates a ice crystal as Sonic rides on it. Rei shoots beams from her hands as she shoots at Sonic, but Sonic maneuvers the ice dodging them.
Rei: Grr...! Take this!
Rei uses her vines to grab Sonic, but Sonic jumps out of the ice and runs on the vines. The vines goes to grab Sonic, but he grabs his kunai blades and slashes it onto halves.
Sonic jumps up as more vines goes towards him, but Blanc's axe attacks the vines protecting Sonic.
Sonic: Blanc!
Blanc: Right!
Sonic and Blanc goes up in the sky as Sonic spins like a ball.
Blanc: Go!
Blanc uses her axe to give Sonic a boost moving in fast towards Rei.
Rei: What?!
Neptune flies with Sonic as she was in front of him.
Rei: Hragh!
Rei shocks Neptune, but it was a fake as it creates smoke.
Rei: No way!
Sonic, Neptune: Haaaa!
Sonic and Neptune goes through the smoke as Sonic and Neptune both attacks Rei sending her into the continent.
Rei: Grahhh!
Sonic charges up a beam from his hand as it was getting big.
Sonic: Super Sonic Blast!
Sonic fires a super blast as it goes for Rei.
Rei: Wahhh!
The blast contacts Rei as it explodes.
Sonic: Hmm?
Rei was still up as she was laughing.
Rei: Hehe... Hahaha...!
Everyone: Huh?
Rei: You're too late! I've already taken enough Share Energy to destroy the world.
Neptune: Destroy? Didn't you want this nation for yourself?
Rei: Are you retarded? I couldn't care less about that! What I really want... is to lay waste to everything.
Sonic: What?
Neptune: Why? Aren't you a CPU too?
Rei: Yeah, I am. Yet all they did was bitch and whine. They never obeyed me!
Sonic: Huh?
Neptune: "They?"
Blanc: Tari cracked down on citizens that showed any discontent toward their CPU. That made lose faith in her, and the nation eventually lost its Shares and collapsed.
Vert: The so called "Great Tari Crash.
Vert: Sounds like we reaped what she sowed.
Rei: You're wrong! They stole my nation from me. This time, I'll be the one doing the stealing! Recharge!
Rei charges her laser cannon again.
Neptune: I feel so sorry for you. You never had any friends, did you?
Rei: ...
Neptune: I'll offer you my sympathy, but you can never have our world!

[There should be a GIF or video here. Update the app now to see it.]

Rei: I'm going with maximum output for the next one. Your petty magic won't be able to stop this!
Neptune: Vert. Noire. Blanc. Uni. Rom. Ram. Nepgear. Sonic. Lend me your strength!
Sonic: Let's go!
Sonic and the others flies towards her.
Rei: I bet you're just gonna try and destroy the Pong Laser. Wonder if you can pull it off before it finishes charging.
Blanc uses her axe on Neptune as Neptune uses her sword giving her a boost.

Blanc: I'll send ya flying there at the speed of light!
Neptune flies faster going in the opposite direction.
Rei: Where are you even aiming?
Uni: Eat this!
Uni shoots at Rei, but she blocks it with one of her wings.

Rei: That doesn't even tickle!
Neptune flies over to Nepgear as Nepgear uses her weapon on Neptune giving her a boost.

Nepgear: Take care of this, sis!
Neptune flies faster as she goes for the laser.
Rei: Not on my watch!
Rom, Ram: Ice Sanctuary!
Rom and Ram shoots ice at Rei, but she blocks it.

Rei: It's all pointless!
Rei goes shock Neptune, but she dodges it.
Vert: Go, Neptune!
Vert uses her lances clashing with the lightning.

Rei: That's charged enough!
As Rei tries to fire it, Noire quickly takes out the other wing with her sword.

Rei: N-No...
Noire: If you got it out, I can cut it off!
Rei: You piece of shit!
Rei notices Neptune going to the laser.
Rei: You're not getting towards it!
As Rei tries to shoot Neptune with her hands, a blast clashes with hers causing smoke.
Rei: What?!
Sonic: Hrraghh!
Sonic comes from the sky and dives down towards Rei and grabs her down.
Rei: You...!
Sonic brings out his kunai blades as they both clash with their weapons.
Sonic: Haaa!
Sonic attacks her with his blade sending her back.
Sonic: Go, Neptune!
Rei: Grahh! I had enough! Fire!
Neptune: Victory Slash!
As soon as the laser fires, Neptune uses her special attack slashing through the laser as the continent falls.

Neptune escapes as she flies back to the others.
Rei: My continent...
Neptune: Give it up. What you desire will never come to pass.
Sonic: It's over.

[There should be a GIF or video here. Update the app now to see it.]

Rei: Hehe... hehehe... Did you really think that sinking my continent was all you need to do to win?
Rei creates a big energy ball with her hands.
Rei: Hahaha! If I unleashed the energy I have now, I could send half the world flying, you know? Hahaha!
Vert: Indeed. The hatred is surprisingly strong  this one. However...
Blanc: In the end, hatred is all it is.
Noire: It doesn't matter if we use up all our Share Energy.
They all were grabbing each other hands.
Neptune: There's only one job that we goddesses have. Right? Sonic?
Neptune reaches her hand to Sonic.
Sonic: Yeah.
They all circle Rei as they hold hands.

Rei: Yeah, yeah, play hero all you want... in the afterlife!
Rei fires a massive blast as it creates a massive explosion.

The dark clouds clear out as everyone was surprised.
Girl: Girls... Blue boy...

Everyone else follows to where a huge crater was as Sonic and the others were laying on the floor. Rei still wakes up as she charges a little bit of a blast in her hand.
Sonic: Gh...!
Sonic slowly wakes up as she sees her charging up a blast.
Sonic: No...
Neptune: S-Sonic...
Sonic: Gh...!
Rei: You...
Sonic slowly walks towards her and charges up a blast, but it vanishes as he falls down.
Sonic: Gh... I don't have any power left...
Rei: I can still do this! I can blow them up, at least. And then I'll crush the world to bits and pieces-
Arfoire: I'm afraid we have a problem.
Rei: Huh?
Sonic: It's you...
Arfoire: This world is gonna be mine someday.
Rei: Say what? Who're you?
Warechu: All good, old hag.
Arfoire: Off to the dark abyss of despair with you!
Arfoire throws the last anti-crystal as it traps the Share Energy causing it to break into pieces. The blast vanishes as dark energy flows out of her.
Rei: N-No! My powers!
Neptune and the others slowly wakes up sees Rei losing her powers as she turns back to normal.
Warechu: We finally got an anti-crystal back, but should we really have used it for this, old hag?
Arfoire: Let's say I decided it on a whim.
Arfoire and Warechu walks off.
Neptune: Wait! Did you help us?
Arfoire: Don't be stupid. I will always and forever be your enemy.
Neptune: Oh, okay.
Sonic: I see. Then we'll take you on anytime.
Arfoire: Hmph.
Neptune: But just for today, let me express my gratitude. Thank you, Bar Whore!
Arfoire: Who're you calling a bar whore?!
Sonic: Haha! Haha...Ugh...
Sonic lays back in the ground.
Neptune: Sonic!
Nepgear: He's just tired.
Neptune: Yeah.
Histoire and the others runs towards Sonic and the others.

A few months later:
The city of Planetune was being rebuilt as the goddesses and the others were in the roof dressed up.
Histoire: Thanks you your efforts, we recovers our Shares, and stand here today to celebrate the completion of the new Planeptower.
Sonic comes in with his suit as everyone was surprised.
Everyone: Wow.
Sonic: So, how do I look?
Neptune: Looks great on you, Sonic.
Sonic: Hehe. I guess I could say the same thing.
Neptune: Hehe.
Noire: You two have been a lot closer now.
Sonic: Well, a lot has happened.
Neptune: Have your Shares remained stable since then?
Vert: Of course.
Noire: We merely had them stolen by Tari. We hadn't lost the trust of our people.
Blanc: No problems, here, either.
Neptune: Good to hear.
Neptune: Let's begin the ceremony, then.
Ram: Sis.
Rom: You gotta say it.
Blanc: Hey, Neptune. How should I put this? Uhh... Back then...
Neptune: Are you talking about the time you attacked me?
Blanc: I'm sorry. I felt like you'd taken advantage of our treaty of friendship, and all I could see was red.
Neptune: Frankly speaking, it was kinda fun fighting you all out for the first time in a while. So I came up with an idea.
Blanc: What idea?
Neptune: I'll tell you later.
Sonic and the others starts walking to the ceremony.
Sonic: (Man, I wish I had a trophy or something...)
The flags raises up as Neptune walks in.
Neptune: It's all thanks to your faith that we were able to complete the new Planeptower. The city of Planetune is recovering by the day, too. As this nation's CPU, I'm grateful to you all. And also...
Neptune looks back at Sonic as he was confuse.
Neptune: I'm also grateful to Sonic.
Sonic: Huh?
Neptune: Sonic, over here.
Sonic walks to where the other goddesses are.
Neptune: Thank you so very much.
Sonic: Hehe.
Neptune: As my token of gratitude I make you as the CPU Warrior.
Sonic: CPU Warrior?
Neptune gives Sonic a medal and puts it on his neck.
Sonic: Whoa...
The audience cheers for Sonic as Sonic was embarrassed a bit.
Neptune: Oh, and one more thing. I'd like to take this opportunity to make an announcement. And that is... One moment please.
Neptune transforms back.
Neptune: Yeah, I gotta do it in this form! Well... I, Neptune, Planetune's CPU, on this day, declare the treaty of friendship null and void!
Everyone: What?!
Neptune: There's no need for that old thing anymore. We're true buddies now! Don't you agree, Noire, Vert, Blanc?
Noire: I suppose.
Vert: You want to compete fair and square from now on, I take it?
Blanc: I guess even you can be clever once in a while.

[There should be a GIF or video here. Update the app now to see it.]

Sonic: Heh, nice job, Neptune.
Everyone claps and cheers.
Neptune: Sonic.
Sonic: Hmm?
Neptune transforms again and kisses Sonic in the lips as Sonic was surprised.
Sonic: Neptune?
Neptune: It's kinda embarrassing to say this, but... I like you.
Sonic: Neptune...
Everyone else smiles as Sonic then smiles as well.
Sonic: Same here, Neptune.
Neptune: I'm glad. Besides, you're my special warrior.
Sonic: Huh?!
Neptune: Hehe.
Noire: Anyway, how about we hold an exhibition match right now?
Blanc: Let's do this!
Vert: My heart's all aflutter.
The three goddesses brings their original outift as they fly off.
Sonic: A match? This'll be my first time having a match against goddesses. Alright! Bring it on!
Sonic flies off.
Neptune: Hey, wait for me! I'm the protagonist here!
Neptune flies off with the others.
Nepgear: Uni! Rom! Ram!
The other four flies off with the others.
Uni: Count me in.
Ram: We're gonna show them we're the best!
Rom: Yeah, the best.
Histoire: Looks like things are going to get chaotic again.

In the grasslands:
Sonic and the others were laying on the floor as they were all tired.
Sonic: (A good time to relax.)
