My idea for the tv series that will air during the 50th Anniversary of Kamen Rider is to have a Rider family of sorts, a show which I will refer to as Kamen Rider Shinren (New Lead).

The three main Riders would be Yonsei Seijikawa, his older sister Mijo Seijikawa, and their father and original Shinren Hngo Seijikawa.

The main theme with this season is family and legacy, which would not only be reflected with the Seijikawas own relationships but also with how they advance the Engine system used to become Kamen Rider Shinren.

This point of contention would come from their differing philosophies on evolving their weaponry, reflecting a specific era of Kamen Rider: Hongo believes in a more simplistic fighting style and has no (Showa), Yonsei would favor augmenting the Driver with Motors (show collectible) and have a flashy battle style to inspire the people of Bouken City (Heisei Phase 2), while Mijo would favor a balance between the two, believing that a flashy fighter can work so long as their mechanisms can't interfere with their justice (Heisei Phase 1). In the end, all three acknowledge the other's points and would instead decide to evolve the system their own way, forging a new future using the Engine as a basis (Reiwa).

Transformation Device:

The belts used by the main Riders are known as Engines (similar to how the mass-produced drivers in Zero-One are known as Risers and the devices used by the swordsmen to transform are referred to as Seiken.) They would have a similar appearance to the Typhoon, with Yonsei's belt in particular possessing a more modern look to it.

With the standard Whirlwind Engine (which simulates a windmill) and the Cyclone Engine, Yongou can don on the armor of Kamen Rider Shinren to fight against SPARK RECALLS.

Motors are a type of machinery created by Yongou via messing around with the remains of the Recalls. By attaching them to the Whirlwind Engine, he can access different forms based on the various elements. The Motors are circular in design, and possess a mechanical look to them.

Villains:

SPARKS RECALL is the newest iteration of SPARKSTER (an allusion to Shocker), who seek to create the ultimate life form while possessing a low view of people who do not follow their beliefs.

They utilize monsters known as Recalls, which are meant to represent the various antagonistic organizations that have appeared throughout Kamen Rider.

Other Details:
-Mijo would become the secondary rider, known as Kamen Rider Shinni (an allusion to Kamen Rider Nigou)
-Hongo would eventually become a Rider once more, using a belt that Yonsei built for him as a gift to become Kamen Rider Shinkai
-Yonsei and Mijo would have catchphrases while Hongo absolutely refuses to indulge in such an act. If an enemy particularly pisses him off, however, he will snap some snarky remark at them before transforming.
-Yonsei's Catchphrase: "Advancing the family's legacy! Protecting those I can protect! That's Kamen Rider Shinren to you!"
-Mijo's Catchphrase: "Let it be known, that I have already won the war."
-The basic idea behind this show is to first start by looking at the various aspects of Showa and Heisei Kamen Riders and making fun of them while also respecting them at the same time.
-Possible conversation between Riders: (Hongo: "Why are you making all those weird movements when transforming? It's just delaying the time it takes to from the armor." Yonsei: "Weird!? You fought against a guy in a football costume that one time! You do not get the right to call my henshin seuqence weird!")

AND that's the general gist for my idea for an anniversary. May jot some more ideas later on, but for now, that's all I have on the matter.
