[Kamen Rider] Collecting Riders, Starting with Kuuga

The world is on the brink of a devastating crisis, but there is only one Kamen Rider left who can fight.

Mayusumi Shinra, who became Kamen Rider Testament just one month ago, is facing this seemingly hopeless situation.

Fortunately, she has the ability to "make vows with other people."

And so, a miracle that transcends time and space comes to pass.

Shinra: "One phone call from me, and a hundred Kamen Riders will be waiting outside your house. Tell me, are you scared yet?"

-

"So you know her, too?"

"Yeah... Maybe we're more than just acquaintances."

Warnings:

Plot-driven quick transmigration, with episodic arcs and a major overarching storyline.

There will be a lot of collecting characters, and extensive individual character arcs. Expect canon couples to be split up, a Mary Sue protagonist, and OOC. Feel free to pick your favorite.

Currently planned series, in order, with rough outlines already done: Kuuga, Ryuki, Den-O, and others to be decided, including more than just the Heisei era...

A growth story: the protagonist becomes invincible later on, but has to level up early on.

Writing this for myself, powered by love. Updates depend on inspiration and the number of comments. Thanks in advance to everyone who leaves a message!

The cover features an original character commissioned from an artist.

Theme: Even if I have to fight alone, I am not truly alone.
