Kamen Rider: Hunting the Old Ones in a Cosmic Horror World

[Kamen Rider + Cthulhu Mythos + Ex-Aid from the start + Original protagonist + One heroine]

Transmigrate to a Lovecraftian Tokyo, where unspeakable horrors are everywhere?

Kamishiro Tenzan calmly pulls out a Gamer Driver.

“Henshin!”

[Level 2! Gashat!]

A Slit-Mouthed Woman comes right up to his face to claim his life? Activate the Game Area and land a physical critical hit that forcibly drains her health!

An evil god’s mental corruption? Split into two personalities with the Twin form and ignore the SAN loss!

From Ex-Aid’s Invincible Gamer to Zero-One’s Metal Cluster Hopper, and then to Saber’s King of Arthur sword.

The campus belle, Chiyuki Yuzuki, trembles at the sight of gods strewn everywhere. “Kamishiro, I asked you to exorcise them, not beat the Old Ones into crafting materials!”

This Rider Kick pierces the stars and the abyss!
