(Sora has finished repairing his Dreadriver as he smiles.)
Sora: And... we're done!
Kagerou: This is the part we leave.
Sora: Agreed.
(Then they leave Gosha-Kagura Academy without saying goodbye to anyone.)
(Meanwhile, Yokaiser is seen facing Devil Gundam as he punches him with a flaming punch. Devil Gundam then kicks Yokaiser away. Yokaiser then summons his Origami Sword and strikes a swarm of Origami Birds, but Devil Gundam isn't fazed by them, and he punches Yokaiser away. He then blasts him, bringing Yokaiser on his knees.)
Devil: You should've known better than messing with Diodora from the house of Astaroth.
(Suddenly Devil Gundam is attacked by a trio of girls.)
Fubuki: You will regret this!
Devil: (smirks) I don't think so!
(Diodora prepares to attack again, but then a racing car hits him, sending him sprawling.)
(Suddenly, a Kamen Rider comes out of it along with some girls.)
Devil: (gets up) WHO DARES HARM THE MIGHTY DEVIL GUNDAM
A. Sango: I do, devil!
(He then charges at Devil Gundam, and punches him before kicking him as he jumps off.)
A. Sango: RIDER KICK!
(He kicks Diodora in the chest, and he screams in anger.)
Devil: THIS CAN'T BE HAPPENNIIIIIIIIIING!!!!!
(As Diodora explodes, the Kamen Rider removes his helmet, revealing to be Kango Fuuma.)
Yokaiser: Kango? Is that you?
Kangou: It's been a long time, Kutaro! As you can see, I'm a Kamen Rider too. Call me... Kamen Rider Ancient Sango.
(Tokiko suddenly approaches Kangou and makes out with him.)
Tokiko: I never get tired of this, onii-chan.
Kangou: Hehe, me neither, onee-sama.
(Cut to Playtime Factory, the Alchemist Federation returns as Poppy greets them.)
Poppy: Welcome back, Master Kagerou.
Kagerou: It's good to be back to the true home sweet home. (Sora groans in pain) Eh? (notices Sora groaning in pain) Sora!
Sora: Ugh! Calm down, sensei. I'm fine.
Harumi: Don't worry, Kagerou. We'll be there for Sora this time. All of us.
(Harumi takes Sora to rest as Black Swan follows them. Ruan Mei turns to her husband.)
Ruan Mei: So... what now?
Kagerou: We resume our operation!
Ruan Mei: You mean...?
Kagerou: Yes, resuming the "Purification of the entire Union Academy" Operation!
(As the screen fades out, Asagi and Tokiko make a high five before disappearing like ninjas.)
