(The Guardians of Life are seen chasing after Sirzechs who is carrying Broly's unconscious body. Suddenly some Devil Soldiers are seen coming in.)

Sonic: Shoot.

????: Leave them to me.

X: Huh?

(Everyone turns to see Hajime Midoriya.)

Zero-One: Uncle Hajime?

Hajime: I can see you've decided to join a noble cause. I'll help you guys.

VAIL DRIVER!

(Hajime pulls out a vistamp.)

KABUTO!

(He stamps the driver.)

DEAL!

Hajime: Henshin!

BANE UP! HAKAI! SEKAI! KIKIKAIKAI! KAMEN RIDER VAIL!

Vail: Come at me, you demons!

(The Devil Soldiers charge at Vail, who fights some of them. OOO keeps chasing after Sirzechs while the other Riders help Vail to deal with the Devil Soldiers.)

(Sirzechs flies up to a building under construction, but notices that OOO is chasing after him.)

Sirzechs: Persistent.

OOO: You have no idea of how persistent I can be.

(He changes the core medals and scans them.)

SUPER! SUPER! SUPER! SUPER TAKA! SUPER TORA! SUPER TATTA! SU-PER! TATOBA! TA-TO-BA! SUPER!

(OOO changes to Super TaToBa Combo, and suddenly Decade shows up.)

OOO: Decade?

Decade: You're not fighting him alone!

(Decade pulls out a card and places it on his Decadriver.)

KAMEN RIDE: FOURZE! COSMICSTATES! COSMIC ON!

Decade (Fourze): Our bonds will take on the universe!

Sirzechs: (glares) It's the last time someone goes against us, the rulers of this world!

Decade (Fourze): Let's settle this.

(Decade charges at Sirzechs and hits him while OOO does the same. They do their best to bring him down. He grabs them and throws them.)

Sirzechs: Prepare to die!

(Sirzechs launches a powerful destruction spell, but Decade manages to repel it.)

Decade (Fourze): Time to finish this.

OOO: Okay!

FINAL ATTACK RIDE: F-F-F-FOURZE!

SCANNING CHARGE!

(Decade covers the Barizun Sword in cosmic energy before delivering a powerful slashing maneuver, and then OOO jumps to the sky before kicking through Sierzechs.)

OOO: SEIYAAAAAAAA!

(Sirzechs screams in pain and explodes.)

OOO: We did it.

Decade: Yeah, but it's not over yet.

(Broly suddenly wakes up and angrily transforms again. Now the final battle is about to begin.)
