(Izuku is seen in his house as he remembers the scene of a beaten Bakugo and various students scared of him.)

Izuku: Did I really do that?

(Suddenly Inko comes in.)

Inko: Are you alright, my baby boy?

Izuku: I don't know... I somehow beat someone mercilessly during combat class.

Inko: Did you say "mercilessly"?

Izuku: Yeah.

Inko: So he returned.

Izuku: Who returned?

Inko: Your real father's inner demon, Kagerou.

Izuku: Kagerou?

Inko: Yes, your real father is Daiji Igarashi, Kagerou's previous host.

Izuku: My father... died?

Inko: Unfortunately. He and his siblings fought alongside the first founder of Union Academy, Hiromi Kadota.

Izuku: Souichi's father...

Inko: They were planning to expose the current Union's wrongdoings, but... (sobs) they died...

(Izuku gets shocked by finding out that his real father died.)

Inko: And it turns out that Kagerou found a new host, which is you. He possessed you due to a certain problem you hold.

Izuku: You mean...

Inko: Kagerou manifested itself because of your inferiority complex. That's how you did what you did.

(Izuku then gets silent for a while.)

(Meanwhile, Souichi is seen in a new home as he watches some news.)

Lisa: Breaking news, a singer named Maria Cadenzavna Eve got captured by the former Atlas Scientist named Arthur Watts. His motives are unknown. We'll show more of this news as we get it. Back to you, Cyril.

Souichi: I'd better take action about this.

(Then Souichi goes out of his new house and goes after the criminal.)

(Back to Izuku, he is confronted by Kagerou himself.)

Izuku: Kagerou?

Kagerou: Yes, that's my true form, believe it or not.

Izuku: And what do you want now?

Kagerou: I want you to betray Union Academy.

Izuku: What? How?

Kagerou: There will be an announcement of a traitor among the Union Students. And once you're asked about it, you will punch through one of the so-called star students, cut the second one's right eye and rip off the third's left arm. But it will be up to you if you want to do it or not.

(Izuku thinks for a while as he remembers the moments he was looked down, and then he makes his decision.)

Izuku: Okay... I'll do it!

(Back to Souichi he sees Arthur Watts in a mech, and decides to transform into Kamen Rider Demons.)

Souichi: I will lay down my life...

DEMONS DRIVER!

Souichi: If it means to save the girl.

SPIDER!

DEAL!

Souichi: Henshin!

DECIDE UP! DEEP. (FUKUAKU) DROP. (OCHIRU) DANGER. (KIKI) KAMEN RIDER DEMONS!

(Souichi becomes Kamen Rider Demons, and then the mech jumps to a building.)

Demons: I guess I'd better do something about it.

(Then he pulls out another vistamp.)

Demons: Perfect.

BATTA!

(Then he stamps the driver again.)

ADD!

(Demons prepares to use his genomix.)

DOMINATE UP! BATTA! GENOMIX!

(Then Demons' legs change and he jumps to the top of the building, where Watts' mech then shoots some missiles, but Demons slashes them with his Batta Legs.)

Demons: Is that the best you've got?

Watts: No, but thanks for asking!

(Watts then commands his mech to shoot a plasma beam, but Demons manages to dodge, and then he charges at the rider, who then slashes the mech, leaving Watts vulnerable.)

Watts: Not bad, kid. But this won't save you!

(Then Watts' mech shoots various missiles, but Demons' Batta Legs slash them, and then the turret. Demons deals great damage on Watts' mech.)

Watts: Enough games! Prepare to die!

(Watts' mech takes distance and shoots more missiles, but Demons jumps on some of them until he reaches the mech again and slashes its missile launcher off. Watts' mech is brough down, or Demons thought so.)

Watts: I'm not done yet!

(Watts' mech kicks Demons to a clock tower, the rider gets up and prepares to destroy the mech once and for all.)

MORE!

BATTA DEMONS REQUIEM!

(Demons leaps into the air and curls his body into a ball, avoiding one of Watts' mech's remaining projectiles as a result. He then spins while falling towards Watts, crashing through more projectiles in the process before performing a flying dropkick with both grasshopper legs. The kick briefly collides with mech before knocking Watts back. Then he catches Maria as the mech explodes. Then he jumps with her to the top of another building before reverting back to Souichi. Maria blushes by seeing him, and then Souichi passes out.)

Maria: So cute... don't worry, baby. Mommy will take good care of you.

(Then she carries Souichi in bridal style as she walks away while the police officers arrest Watts.)

(Meanwhile at Union Academy, it looks like another ordinary day until Nexu talks through speakers.)

Nezu: Attention all of Union students. We have a serious problem. Some of our files have been stolen lately. There is a traitor among us.

(This catches the students in surprise, except for one, who is seen smirking. The one is none other than Izuku Midoriya. Then Jaune approaches him and asks.)

Jaune: Izuku, do you know who is the traitor?

(Izuku is silent.)

Jaune: Answer. Izuku!

(Issei approaches the duo, and then Izuku smirks as he suddenly punches through the red dragon emperor's chest.)

Rias: (shocked) ISSEI!

(The other students get shocked by seeing Issei being severely hurt by Izuku, who then looks at them.)

Izuku: That's right! I am the traitor! Kagerou, give me your power!

(Then Kagerou possesses Izuku, and pulls out the Two Sidriver and places it on his waist before pulling out a vistamp.)

BAT!

CONFIRMED!

EENY MEENY MINY MOE! EENY MEENY MINY MOE!

Kagero: Henshin!

VERSUS UP! MADNESS! HOPELESS! DARKNESS! BAT! HEHE! KAMEN RIDER EVIL! YEAH-HAHA!

(Then Kagerou becomes Kamen Rider Evil.)

Evil: Hehehehe!

(Cardin recklessly charges at Evil, who then slashes one of his eyes.)

Cardin: AAAAAAAAAARRRRRRGH!

Russel: (shocked) CARDIN!

Dove: OOOOH NOOOOOO!

Sky: (scared) Oh crap!

(Then Yang engages Evil in a fight. They seem to fight evenly matched, but Evil stamps the Bat Vistamp onto the emblem on his chest and fires green sonic waves from it that attack the Yang's hearing. Then she has had aenough and tries to punch Evil, who then slashes one of her arms off.)

Evil: You will live for now. But remember. Next time you mess with us, YOU WILL DIE!

(Then Evil leaves while his laugh echoes through the entire academy, making the students shocked. Unbeknownst to them, they won't have only one enemy.)
