(Leonard is seen going in a date with Itsuka.)

Itsuka: Isn't this awesome, dear? Our first date.

Leonard: Quite amazing, isn't it?

(Then Leonard sees an ice cream truck)

Leonard: How about we have an ice cream?

Itsuka: Good idea.

(Then the couple approaches the ice cream truck.)

Leonard: Two ice creams please?

Ice Cream Man: Which flavors do you want?

Leonard: Chocolate.

Itsuka: Strawberry.

Ice Cream Man: Okay.

(Then the ice cream man gives their respective ice creams and they pay him. As they resume their date, suddenly Leonard spots something.)

Itsuka: Are you okay?

Leonard: It looks like the muscle guy is up to no good. This is unforgivable!

(Leonard clenches his fist as he prepares to transform.)

Leonard: Hen...shin!

(Leonard becomes Kamen Rider Black.)

Black: Kamen Rider! Black!

(Then Black jumps and kicks Muscular from behind before punching him. But Muscular punches him back, sending him sprawling. Then he tackles him and tries to slam him to a wall, but Black manages to throw Muscular against it.)

Muscular: Now you've done it!

(Then Muscular uses his quirk, strengthening his muscles.)

Black: So this is your quirk, you use it to become stronger.

(Then Black kicks Muscular, who then charges at him, but he dodges and tries to attack him, but gets shoved aside. Suddenly a familiar figure comes in.)

Jaune: You're fighting with me now, villain!

(Then Jaune makes a driver appear in his waist.)

Jaune: Henshin!

(Jaune becomes Kamen Rider Kuuga. Muscular throws some rocks at him, but Kuuga kicks them away. Black gets up.)

Black: ENERGY TANK!

(Then Kamen Rider Black uses his energy tank, and charges at Muscular, chopping one of his arms. Then he prepares to finish him.)

Black: RIDER PUNCH!

(Black punches Muscular, sending him sprawling. Then he looks at Kuuga, and both nod at each other.)

Black/Kuuga: RIDER KICK!

(Then both Black and Kuuga kick Muscular, and the villain screams in pain before exploding. Then a little girl is seen approaching the duo.)

Black: Did he hurt you?

(The girl nods, and then Black carries her, and the four leave the scene.)

(Timeskip)

(Leonard is seen with Jaune, Izuku, Ochako, Momo and Shoto along with the girl named Eri.)

Leonard: And that's how my brother and I defeated that villainous big muscles.

Jaune: Yeah, that was awesome. You had to watch my transformation.

Shoto: They would like to see it.

Jaune: (confused) Who?

Shoto: Your teammates. They would be proud of you.

(Suddenly some plates of sushi are seen.)

Leonard: Oops, it's time to eat.

Izuku: Sushi must be delicious.

(Eri takes a bite of the sushi.)

Eri: This is good.

Leonard: (eats a sushi) This sushi is divine.

Ochako: Indeed, they're the best around.

(Then they laugh a bit before resuming their eating. Suddenly Pony and Yui come in.)

Pony: Leonard, can we talk.

Yui: It's very important.

Leonard: Sure. (to the others) Excuse me, guys. I'll be back.

(Then Leonard goes with Pony and Yui.)

Leonard: So? What do you want to talk about?

Pony: Well, we know you're dating Itsuka, but...

Yui: We want you to know that...

Pony/Yui: We love you, Leonard.

Leonard: Wow, I'm flattered. But I need to talk with Itsuka before...

Itsuka: (comes in) Well, I don't mind sharing.

Pony: (excited) Really?

Itsuka: Of course, you're my best friends.

Yui: (bows) Thanks, Itsuka. (to Leonard) We'll become better girlfriends for you, we promise.

(Then Leonard hugs Yui, who then smiles a bit. Pony then hugs him, and so does Itsuka.)

(Leonard's life is getting even better, and now his brother Jaune is a Kamen Rider too. What surprises await our hero?)
