(Tokuro is seen in his demon form, much for the heroes' shock.)

Asia: You're a devil too?

Tokuro: To be honest, I came from hell itself.

(This shocks the heroes)

Tokuro: Surprising, isn't it?

Horobi: So you were never a human.

(Tokuro nods.)

Jin: And how did you come here.

Tokuro: The most accurate word would be "why". Anyway. I'm the adopted son of Vail... (George gets shocked while Tokuro turns to the Igarashi trio.) He may have done some bad stuff to your family before, but he changed. Once he found me, he raised me like I was actually his son. Whatever he did a long time ago, it was the reason why he died as he didn't have much time. So he gave me this. (shows his Crimson Vail Vistamp) And then he told me to come here because of how corrupt Union Academy had become.

George: You said you're Vail's adopted son, correct?

(Tokuro nods, and then George shows him the Vail Driver.)

George: This is the Vail Driver. Use this and you can fight as a hero.

(Tokuro catches the driver and prepares to join the heroes in their fight against Union Academy.)

(Timeskip)

(The Riders, including the rebuilt MetsuboJinrai.Net prepare to infiltrate Atlas' Underground Base as they go into the underground cave.)

Ryuga: All right, let's get started. Our mission's to investigate the Atlas-affiliated research center somewhere in that area. According to the intel from Azur Lane, the lab's been dumping illegal waste into those sewers. FYI, they're also involved with the cartels in human trafficking. Allegedly, anyway.

Izuku: This just gets better and better.

Horobi: We will scout just ahead. You guys will provide backup.

Souichi: Sir, yes sir.

Jin: Commencing operation!

INFERNO WING!

Jin: Henshin!

SLASHRISE! BURNING FALCON! THE STRONGEST WINGS BEARING THE FIRE OF HELL!

(Timeskip)

(The heroes are seen in their rider forms as Jin then hears some screams.)

Jin: Guys, there's someone in these sewers.

(Then Vail sees the girl, who is a beautiful spider angel being surrounded by five Atlas Soldiers. He then decides to jump down and kick them all.)

VAILING IMPACT!

(Vail covers his hand in crimson energy and punches the Atlas Soldiers. Simultaneously, an energy construct of a rhinoceros beetle appears from behind Vail and impales the soldiers as the punch makes contact. The Atlas Soldiers then explode.)

Vail: That should teach them. (turns to the girl) Are you okay?

????: I am now.

Vail: What's your name?

????: I am Molly Dust. I'm an angel from heaven. But my former master betrayed me and my brother when he found out that we allied ourselves with Sirzechs' archenemy Lucifer himself.

Vail: This sucks.

Molly: My brother could escape, but I wasn't as fortunate as he was. Then the Atlas Soldiers tried to take me to their lab, but then two androids busted me out and gave me the coordinates to escape. But I got caught. And I'm afraid they might find out about the two androids betraying them. (pats Molly's shoulder) Molly, I need every detail about who and how they helped you to escape.

Molly: Oh...

(Timeskip)

(The heroes are seen ready to infiltrate the laboratory as they are close to the entrance.)

Horobi: Okay, Jin. You just need to find Penny and Ciel. Once you do, hack them and turn them against those Atlesian bastards. I'm counting on you, son.

Jin: (nods) Roger that.

(Then the heroes, except for Vail, go ahead. They take down some Atlesian soldier, and then suddenly they see some missiles being shot. They turn to see a MG named GRAD.)

Demons: The bastard is blocking the way! We'd better push it back!

(Demons then pulls out the Scorpion Vistamp.)

SCORPION!

ADD!

DOMINATE UP! SCORPION! GENOMIX!

(Demons adds the Scorpion Genomix and tries to hit GRAD, landing various hits, but gets pushed back, and then Jin tries his luck, but gets shot by a missile. Live lands some hits, but gets pushed back. Jeanne gets to push GRAD away, but it changes to its battle mode.)

Demons: It has switched to biped mode. We gotta be careful! It is whole new battle now!

(Then Demons lands some hits on GRAD and even dodges one of its punch. He keeps assaulting GRAD, but then gets dazed by its counter attack. GRAD then shoots some missiles, but Horobi destroys one of its shields before landing some hits until the UMG runs over him. GRAD then shoves Revi off and blows Vice away. Jin lands various hits on the UMG and even slashes off its other shield before resuming his fight with him. Then Jin gets hit and Live tries his luck, but gets kicked as well. Naki charges at GRAD and slashes the mech with his claws. As he deals enough damage, he prepares to finish him.)

ZETSUMETSU DYSTOPIA!

(Naki runs to GRAD and performs a series of rapid kicks, followed by a single, stronger kick after a brief pause.)

Naki: We surely don't need such surprises for a while.

(Some minutes later, Jin finally finds Penny and Ciel.)

Jin: Found you. You're my friends now.

(Jin then hacks both Penny and Ciel, turning them against the coming Atlas Soldiers as they kill them.)

Jin: I got the androids.

Green Arrow: (comms) Good. We already got the info about General Irondick's next plan. He intends to traffick some people. I didn't think he would give the ones who disobeyed him such cruel punishment. Anyway. You must return to the base and we'll discuss a plan to strike down Atlas once and for all.

Revi: Good, I was already planning on this anyway.

(Then the heroes return to the base as the screen fades out.)
