(At Gosha Academy, a student named Tokuro Kougami is seen inventing some stuff for the Taimanins to help them to fight against the demons.)

Tokuro: Okay, time to test this one.

(Timeskip)

(A few moments later, Tokuro discovers some cell medals.)

Tokuro: Hmm... these ones might be useful for future experiments...

(Then he takes the cell medals in, and some minutes later, he starts doing experiments.)

Tokuro: (smiles) This one will be my biggest feat...

(Two hours later, Tokuro is able to create something with the cell medals.)

Tokuro: Excellent. With this I can help the Taimanins and OOO in their missions.

(Tokuro looks at his own Rider System with admiration, and then feels someone hugging him.)

????: You did it, Tokuro. Congratulations.

Tokuro: Oh, thanks Nanami.

Nanami: You're welcome. But you seem tired. Let me help you.

(Nanami repelinshes Tokuro's stamina, but subsequently gets unable to move. Tokuro carries her in a bridal style as he takes her to the recovery room.)

Nanami: Tokuro...

Tokuro: Yes?

Nanami: One day you'll be carrying me like this again, but in an adorable tuxedo while I'll be in a wonderful weeding dress.

Tokuro: Nanami, you're so cute when you like something adorable.

Nanami: (blushes) Um... just don't start teasing me, okay?

Tokuro: Alright, alright, you win.

(Next day, Tokuro is seen preparing to fight two orcs.)

Tokuro: Henshin!

(Tokuro becomes Kamen Rider Proto Birth)

P. Birth: Now then, let's start earning!

(Birth starts fighting one of the orcs. Then he places a cell medals in his driver.)

B. Driver: Crane Arm!

(Then Proto Birth whips the orc with his Crane Arm.)

P. Birth: How do you like that?

(Then he keeps whipping the orc until he kicks him.)

P. Birth: That's the way.

(Then he uses his other cell medal.)

B. Driver: Breast Cannon!

(Then Proto Birth summons the Breast Cannon.)

P. Birth: Behold my power!

B. Driver: Cell Burst!

(Proto Birth fires a red energy beam that leaves behind a spiral effect, killing the orc.)

P. Birth: I'm impressed I made it, but I still need to deal with the other orc.

(The second orc charges at Proto Birth, who then starts firing shots with his Breast Cannon...)

P. Birth: Maybe I need more than that...

(Then he charges at the orc and starts beating him.)

P. Birth: Try this one for size.

(Then Proto Birth prepares to finish the orc.)

B. Driver: Cell Burst!

P. Birth: Breast Cannon... SHOOT!

(Then Proto Birth shoots the orc down, finishing him, but due to using the Rider system for much longer, he passes out. Then Nanami approaches him, and carries him the same way he carried her earlier.)

Nanami: (giggles) One day, you'll be carrying me like this once we get married, my adorable boy.

(Nanami carries Tokuro away as the screen fades out)
