(Weiss Schnee is seen in her dorm, studying for a test as she sees something she wrote wrong.)
Weiss: Hmm... I guess I did this one wrong.
(She then catches the eraser and sets to correct her answer.)
(Meanwhile Izuku Midoriya is training to improve his control over One For All.)
Izuku: I need... to become... stronger...
(At the hospital Shoto Todoroki is seen visiting his mother.)
Shoto: Happy birthday, mother... I'm sorry...
(And finally, Ichika is seen in his dorm wallowing in his thoughts.)
Ichika: Why does this always happen to me?
(Then the screen splits into four as Dimitrio smirks.)
Dimitrio: I guess I should give the new Ouja a challenge that is well suited to him.
(He then pulls out the Card Decks and throw them to the locations Weiss, Izuku, Shoto and Ichika are, and the decks catch their attention.)
Weiss/Izuku/Shoto/Ichika: What's this?
(They pick their respective card and suddenly learn about all cruel things Union Academy had done, like selling faunus to work as slaves, attempting to destroy the Dragon Continent which became a shelter to both faunus and powerless beings, women raping innocent men and vice versa, Pro Heroes merely fighting to obtain the Number One position, currently belonging to All Might, and then they realize something.)
Weiss/Izuku/Shoto/Ichika: (in unison) I guess I was in the wrong side of story all along.
(At Weiss' dorm.)
Weiss: There might be more Kamen Riders around here.
(At Izuku's training room.)
Izuku: I can't tell anyone else about it.
(As they pick their card decks, they start their preparations for the battle royale. As Ichika walks out of his dorm, he fails to notice Riser watching him.)
Riser: So there are more Kamen Riders, huh? Now this is getting interesting.
(Riser chuckles as he walks pasts his archrival Issei Hyoudou, who pretends to ignore him as he pulls out a Card Deck.)
Issei: ...
(He walks away as a battle royale is about to begin.)
