(Tokuro is seen alongside the Dekusquad at U.A. University.)

Tokuro: So this is U.A....

Tenya: Yep, this is the school where new heroes are born.

Tokuro: Yeah, this place is awesome. Too bad it's not villainproof.

Tenya: Now you've mentioned, there's a group of villains who keep roaming around the city.

Tokuro: The League of Villains, led by the mysterious All For One.

Tenya: Exactly.

Tokuro: He is the archenemy of the past One for All users, especially Nana Shimura and Toshinori Yagi, also known as All Might.

Tenya: (shocked) You know All Might's secret?

Tokuro: Not only that. I also know that since his last fight, he got an injury, and because of that, he can only fight three hours a day.

Tenya: So that's why he had to find a successor.

Tokuro: Exactly.

(As they walk through the school, they reach the USJ.)

Tenya: By the way, this is the USJ, a training room idealized one of our teachers.

Tokuro: The Pro Hero Thirteen. He built this room to train students on how to act through disaster situations.

Tenya: Indeed.

Tsuyu: Ribbit. He told us once that...

Tokuro: Powers are not meant to to inflict harm, but to protect people.

Tenya: Basically.

(Suddenly a black portal opens up, and then Kurogiri comes in along with the League of Villains.)

Tokuro: Great, it's Kurogiri.

Kurogiri: Greetings. We are the League of Villains. Forgive our audacity, but... today, we've come here to U.A. High School—this bastion of heroism...to end the life...of All Might, the Symbol of Peace.

Tokuro: Not if I can stop you.

Kurogiri: You? Who are you?

Tokuro: (pulls out a card) I'm just a passing through Kamen Rider. Remember that. (inserts the card in his driver) Henshin!

Diendriver: Kamen Ride: Diend!

(Tokuro transforms into Kamen Rider Diend.)

Kurogiri: So you're the one who defeated the Sludge Villain... no matter, we will destroy you!

Diend: (pulls out three cards) You're gonna have to go through my personal army first.

Diendriver: Kamen Ride: PunchHopper! Kamen Ride: Dark Kabuto! Kamen Ride: Hercus!

(Then Kamen Rider Diend summons the three Kamen Riders.)

Kurogiri: So you can summon... interesting. But you won't survive. ATTACK!

(Then the summoned Kamen Riders quickly engage the villains, leaving Kurogiri to face Diend himself.)

Diend: (pulls out another card) There's more where it came.

Diendriver: Attack Ride: Blast!

(Kamen Rider Diend shoots various blasts at Kurogiri, giving him no time to react.)

Diend: I was expecting more from you. How disappointing.

Kurogiri: YOU DARE MOCK ME?

(Then Kurogiri tries to use his quirk, but Diend pulls out another card and inserts it on his Diendriver)

Diendriver: Attack Ride: Invisible!

(Then Kamen Rider Diend becomes invisible, and Kurogiri's quirk doesn't seem to have effect as Diend shoots Kurogiri.)

Kurogiri: What the...

(Then Kamen Rider Diend hits Kurogiri while still being invisible until he kicks him away.)

Diend: Hmph. Don't waste my time.

(Meanwhile, the summoned Kamen Riders and the Dekusquad are seen easily dealing with the villains.)

(Back to Diend, he is seen pulling out a card as Kurogiri opens up another portal, and then Dabi, Tomura, Toga and Nomu come in.)

Dabi: So you're the one causing troubles for Kurogiri, huh?

Diend: 5 VS 1? Okay, try to make this interesting for me.

(Suddenly a muscular figure appears, revealing to be All Might.)

All Might: No need to fear, because I am here.

Tomura: (smirks) All Might... right on time for your own downfall. Nomu, ATTACK!

Nomu: PREPARE TO DIE!

Diend: Gee...

(Then Diend sees his summoned Riders and the Dekusquad already restraining the villains.)

Diend: Izuku, you and your squad jump now.

(Kamen Rider Diend inserts the card on his Diendriver)

Diendriver: Final Attack Ride: D-D-D-Diend!

(Then the Dekusquad jumps off as Kamen Rider Diend shoots the villains, killing them.)

Diend: Only the big deals remain now.
