Kamen Rider: What? You're Dumping This Mess on Me?

[Magic + Kamen Rider + original creation + invincible in the early stages + exploring ruins (early stages) + veteran cameos (later stages)]

Bai Yu is a college student and the godfather of seven classmates. After his father died of an unknown illness, he took a few days off and returned to his hometown.

That trip home led ordinary, unremarkable Bai Yu into a new world, a world of magic.

There, he gained the chance to become a “Mage” (that is, a Kamen Rider).

He didn't actually want this opportunity, but the Kamen Rider who suddenly appeared acted like a hands-off boss, handing Bai Yu the transformation item before immediately running off.

So Bai Yu had no choice but to take on the responsibility of protecting the world. But he also came to understand just how difficult that was. Not only did he have to face the terrifying enemies lurking in the shadows, the Aberrations,

but he also had to fight an evil mage from over a thousand years ago, as well as two suits of armor that appeared later and destroyed a kingdom.

Bai Yu: What kind of hell-level dungeon is this?
