Months have passed since Kamen Rider Birthright defeated the Over Quartzer along with his Titan Guardian Athar. Now Percy decides to travel back to America along with his girlfriend Ryuko and her friends to celebrate Halloween. Unbeknownst to them...
(After the chase that ended with the dinosaur skeleton disintegrated, the boy decides to speak up.)
????: My name is Philis Proctor, I'm the descendant of John Proctor II.
Gamagori: John Proctor II?
Percy: I heard about him. He was a Salemite boy who was kidnapped by Luis Proctor when he was a baby, but once he grew up, he killed his evil adoptive father by beheading him and placing his head in a pumpkin.
Ryuko: Was that creature who attacked a boy in the museum one of this Luis' abominations.
Philis: Nope, Skele-Taurus was just brought to life thanks to that bastard's dark magic after your evil stepmother revived him.
Percy: (gasps) Ragyo Kiryuin.
Philis: Yep. Skele-Taurus became a supernatural skeletal dinosaur once Luis, or should I say, Samhain the Halloween Overlord used his dark magic to bring not only it, but all of the Halloween stuff to life.
Satsuki: What about this dragon of yours? Why does it look friendly?
Philis: His name is Nitecore. He's my familiar ever since I used light magic to bring him to life. His real form is a Dragon Balloon. I also create magic traps to keep any intruders from reaching my home.
Percy: I see... (to James) your turn to answer.
Ryuko: Yeah, why did you save us, even though we are your enemies?
James: I wasn't always this abomination.
(He pulls out a picture of his human self.)

James: I used to be like this before that bimbo sent her lackeys to capture me.
Percy: (growls) Mother...
James: She's even cut my arm and replaced it with a metallic one before transforming me into this. She altered my memories, making me believe my uncle was my father.
Uzu: So you're the son of Captain America, not Winter Soldier.
James: Exactly, and now that I'm free from Nancy's brainwashing, I decided to help you in order to start my long road to redemption.
Percy: And your mother is Black Widow, right?
(James nods.)
Percy: I see...
????: So that backstabbing brat has a descendant, huh?
Philis: (stern) It's him...
Percy: Who?
(Samhain then appears uses his wood manipulation to create a giant fence around him and the heroes.)
Samhain: It's time for you to see your doom! HAHAHAHAHAHAHAHAHAHAHA!
(The heroes get in their fighting stance to fight Samhain.)
(As the screen fades out, Samhain uses his flamethower, and writes a "To be continued" on the screen before leaving.)
