Tokusatsu: Saving the World, Starting as an Insect Alien

A Kamen Rider story with a few Super Sentai and Ultraman elements.

Yuma accidentally transmigrates to the Kamen Rider universe. When his memories merge with those in his mind, he discovers that he died long ago and has become a Worm!

And right downstairs from him are a Worm and Hiyori!

Tendo, who should have arrived by now, is nowhere to be seen. With no other choice, Yuma fights with everything he has, only to run into Kabuto, who has just arrived...

I'm a Worm, and I've run into the invincible Tendo Souji?

Yuma is instantly numb with shock, but he still decides to fight for survival in this Kamen Rider universe and become a true Kamen Rider!

A Kamen Rider story must have the spirit of a “Rider.” This is the tale of a villain who is physically an outsider, yet upholds the will of a “Rider” as he travels through the Kamen Rider universe.
