Back in the scene of the battle (after), Devouraz has recovered from the attack. He and some of his goons walked through an abandoned town. He and some summoned goons had escaped from the heroes. Now, he will soon get his revenge on them.

Devouraz: I will..... rule over all the Multi-Verse! Once and for all!

he and his goons were about to take over the town when.....

: BWAHAHAHAHA!!!!!!!!! I'm afraid that's not gonna happen.

that he and his goons then turned around and saw someone in red was being carried into battle on a mikoshi, often by unknown men or women dressed in ceremonial summer festival attire and surrounded by miko who were performing a strange dance. When they stopped, the warrior then jumped and landed in front of them while the group dispersed mysteriously.

that warrior is a red Sentai leader, which is based on Momotaros.

that Red sentai leader is actually Don-Momotaro, leader of the Avataro Sentai DonBrothers - the new 46th Super Sentai team.

Don-Momotaro: Hey! What is going on here? *curious* Is there a battle going on?

seeing this, Devouraz was mad including the goons too.

Devouraz: Who in the world are you? *angry*

looking at the robot, the red Sentai was smirking.

Don-Momotaro: Who am I? I am.... Born from the peach! Don-Momotaro! *posing* And we will stop you.

Devouraz: And who's 'we'? *confused*

that from a flash, two blurs appeared before wiping out the grunts, leaving Devouraz shocked. The blurs then joined Don-Momotaro, revealing their forms.

the first is a Kamen Rider, wearing a Driver with a strange stamp inserted, while the other is his partner. Both of them wore armors which is based on a T-Rex.

both Riders were actually Kamen Riders Revi and Vice. Those two are the new Riders on the block.

Vice: Woo Hooo!!! Now this is a showy style! *looking at the viewers* Hi, Minna! This is Vice speaking! This is the first time we are in a cameo and this is....

well, his Rider partner had caught him by the ear.

KR Revi: Vice! *scolding him* Stop talking! We're in the middle of a battle, you know.

but, it was interrupted by Devouraz, who transformed into Hell Bros Kaiser, that he ran and attacked the trio.

Hell Bros Kaiser: You will all fall! *summoning his blade*

but as soon he slashed, the trio then dodged and leaped into a building.

Don-Momotaro: Really! *surprised* That is really weird.

Vice: Hey! *shouting* That's not fair for butting in!

KR Revi: I don't know but, we need to finish this now! *sternly* Ikuze!

that he removed his ViStamp and activated it.

Rex ViStamp: REX~!!!!!!!!! *before putting it back in the belt*

smiling, Vice jumped before punching Hell Bros Kaiser with multiple punches and kicks before landing. When Revi's inner demon landed, his mouth began to smoke before generating purple-like fire out of his mouth that it burns the gear-like warrior. Hell Bros Kaiser then extinguish the flames and began to chase Vice before looking up before seeing KR Revi, who shifted his legs into T-Rex legs, before running and kicking before Revi landed which reverted his legs back to normal. The gear-like warrior then slashed again, only for Revi and Vice to jump before seeing Don-Momotaro who summoned his Zan-glassSword before slashing multiple times before joining the two heroes.

hurt and damaged, Hell Bros Kaiser staggered back before seeing the trio who were now battle ready.

Don-Momotaro: Sa, let's do this! This festival is about..... to start!

KR Revi: I'm boiling hot! *posing*

Vice: *dong the same pose too* I'm also boiling hot too!

that Revi activated the finisher while Don-Momotaro readied his blade.

Revice Driver: REX~!!!!!! STAMPING FINISH!!!!!!!

Zan-glassSword: Mo~motaro Zan! Momotaro Zan!  Hissatsu Ōgi! Momotaro Zan~!!!!!!

KR Revi and Vice: REVI and VICE STAMPING..... KICK!!!!!!!!!!

Don-Momotaro: Let's do this! Avatar Combat Art!!!!! Momotaro.... Slash!!!!!!!!!!

that Revi and Vice both did a fist-bump before leaping into the air as a purple energy construct of a numbering stamp with cyan numbers then appears from Revi's foot. Initially displaying the number 48, it changes to 49 and then finally 50 when Revi and Vice pass through the construct while performing flying kicks surrounded in spiraling purple and cyan energy, with a pink number "5" on the sole of Revi's foot and "0" on the sole of Vice's foot. A large red projection of the Rex Vistamp's seal is created upon impact, which a blue number "50" attaches to Hell-Bros Kaiser before being rider-kicked. The gear-like warrior looked up before seeing Don-Momotaro, who is standing on a torii, that he leaped off the Torii and activated the Zan-glassSword by spinning its gear five times. He presses the trigger and unleashes a flurry of rainbow colored slashes around Hell-Bros Kaiser, then he rushed fast to the gear-like warrior and began slashing through for the final blow and landed along with KR Revi and Vice. The enemy is then launched backward while leaving behind a vortex of dark blue energy until exploding.

Vice: All together, everyone! *counting down* 3...! 2...! 1...! It's a grand day~!!!!!!!!! WASSHOOIII!!!!!!!!!!

after Vice counted down, the vortex then created multicolored fireworks-like sparks before a second explosive wave occurs before the heroes posed. Devouraz was now....... gone.

Vice: Did you see that! *excited* This is a great day! I hope you watched our series because......

the last thing Vice knew was being pulled by KR Revi by the tail.

KR Revi: C'mon! Partner! *going* We're going.

Don-Momotaro: *smiling at the viewers* And that's all folks! *following them* Wait for me~!!!!!

that both of them walked before the screen turns into the closing screen which shows the Rex ViStamp and the Don-Momotaro's Avataro Gears before it fades away.
