(Four years later, the world has been restored to its normal state and everyone returned to their normal lives. Ethan and Okuyasu returned to their respective universes as they bid him farewell.)

(Percy is currently seen visiting the graves of his father and his brother.)

Percy: Father... brother... rest in peace... justice is finally served.

(Suddenly he hears some beeps, and clicks the button of his communicator.)

Izu: (intercom) Percy, I've got good and bad news.

Percy: What's up?

Izu: (intercom) The good news is that MetsubouJinrai.Net and Azuma redeemed themselves as we finally managed to rebuild each of the four humagears.

Percy: Bad news?

Izu: (intercom) A new Dark Rider is attacking the city.

Percy: I'm on my way.

(Percy turns off the communicator and prepares to transform as the credits roll.)

(Percy is seen running to the school, when he suddenly bumps into someone.)

Percy: Oops, I'm sorry, are you okay?

(He then offers a hand, and the person he bumped into accepts as he helps her up.)

Percy: Look, I'm really sorry about that.

(Then the person is revealed to be a girl.)

Percy: Yeah, I guess so... my name is Percy Howard.
