(In Kamino, Tomura and the League of Villains are seen before their leader known as All For One.)

A. F. O.: You may have failed to kill All Might, but you brought us something useful.

Tomura: His recklessness brought him to us, sir.

Kurogiri: He's speaking the truth, boss. When we were about to leave because a certain armored hero destroyed our Nomu, he...

A. F. O.: Let me understand... an armored guy... destroyed Nomu?

Tomura: Yeah, this was his fault.

A. F. O.: How is his armor exactly?

Twice: (raises his hand) I know that. He was in black and cyan, and wielded a gun with some cards which allowed him to summon some other guys like him.

A. F. O.: Hmm... so that's how Nomu was destroyed... very well, we'll challenge this armored guy to a fight.

Bakugo: Like you're going to win...

Tomura: (glares) What did you just say?

Bakugo: You heard me, I said you will lose. I'm almost sure that All Might will come here and make you run like scared little babies.

(Tomura gets angry and tries to lunge at Bakugo.)

A. F. O.: SHIGARAKI!

Tomura: Yes?

A. F. O.: We need him alive. And he's right. All Might will come here anytime.

Twice: And what are we gonna do? Use him as a shield?

Nine: Hohoho, that's right. Don't hesitate.

(Suddenly someone bursts through the wall, and it's All Might.)

A. F. O.: So we meet again, All Might, for the last time.

All Might: Don't bet on it, All For One.

(All Might and All For One start fighting while Tokuro pulls out a card and inserts it on his Diendriver)

Tokuro: Henshin!

Diendriver: Kamen Ride: Diend!

(Tokuro becomes Kamen Rider Diend, and then he steps into the hideout.)

Tomura: You again?

Diend: (pulls out three cards) That's right. And now you're done.

Diendriver: Kamen Ride: Ixa! Kamen Ride: Saga! Kamen Ride: Dark Kiva!

(Then three riders are summoned.)

Ixa: Tomura Shigaraki! Please return this life to God.

Tomura: Back off. (holds Bakugo) Or this boat's gonna get it!

Bakugo: BRAT?

(Bakugo unleashes an explosion which shoves Tomura aside, and then he starts beating him to a pulp. Meanwhile Saga and Dark Kiva charge at the villains, who charge at them as well. Diend sees All For One getting the upper hand, and decides to interfere.)

Diendriver: Attack Ride: Blast!

(Then Diend shoots some bullets which harm All For One.)

Diend: Go! I'll take him on!

All Might: Are you sure about this, young Diend.

(Izuku comes in, only to be stopped by a psychotic girl.)

????: My name is Himiko Toga, Izuku.

(Then Toga pins him down.)

Toga: You're really cute... (psychotic tone) but you'll be even more once you bleed!

(Suddenly All Might punches Toga away from Izuku.)

All Might: Are you alright, young Midoriya?

Izuku: Yeah, I just got a bit careless.

(Back to Diend and All For One, the villain grows his left arm.)

Diend: The hell?

(Then All For One punches Diend in the gut before punching his face three times.)

Diend: Okay, you fight well. (pulls out two cards) But you're not the only one who plays dirty.

Diendriver: Kamen Ride: Blade! Final Form Ride: B-B-B-Blade!

(Then a big version of Kamen Rider Blade's weapon is summoned and gets on Diend's right hand.)

A. F. O.: Did you just...

Diend: Now we're even.

(All For One tries to punch Diend, who dodges and grabs his arm before elbowing his face and slashing his chest three times. Then he kicks him away.)

Diend: Now for the Finale.

Diendriver: Final Attack Ride: B-B-B-Blade!

(Then Diend spins the Blade Blade, performing the Diend Edge, which hits All For One, killing him, which shocks Tomura.)

Tomura: RETREAT! RETREAT!

(Then Toga smiles at Izuku.)

Toga: See you next time, Izuku.

(Then the villains leave as both All Might and Izuku see Diend, who defeated All For One.)

(Next day, Tokuro and his crew are ready to leave the My Hero Academia Universe.)

Tokuro: Well, I guess it's time.

Tsuyu: Ribbit. Tokuro.

Tokuro: Tsuyu?

Tsuyu: Ribbit. Take me with you.

Tokuro: Are you sure about this?

Tsuyu: Ribbit. Yes. And besides...

(Tsuyu kisses Tokuro in the lips, shocking everyone around.)

Tsuyu: I love you, Tokuro.

Tokuro: I love you too, Tsuyu.

Tsuyu: So? Can I go with you?

Tokuro: Sure.

(Then a portal opens up, revealing the Highschool DXD Universe.)

Tokuro: Next stop, Highschool DXD Universe.

(Then Tokuro and his crew go through the portal. Which new challenges await the treasure hunter?)
