He died because of his own stupidity... and became immortal.
Yup, that’s our “hero” — Zack Monroe, your average American dude who, in a moment of drunken brilliance, jumped off a rooftop yelling: “To the oceaaaan!”
The problem?
There was no ocean.
Just a parking lot… from the tenth floor.

Lucky for him (or not?), Death said: “Nah, you’re not getting off that easy.”
So Zack woke up in Velderra, a dark fantasy world filled with corrupted magic, emotionally damaged demons, and anime-tier lunatics.

With no powers, no real goals, and a brain that’s clearly on vacation, Zack became immortal.
And now? He has to survive with a team consisting of:

An orc who's smarter than most humans,

A catgirl with trust issues (especially toward idiots like him),

A demoness who loves chaos way more than cooperation.


Velderra doesn’t forgive.
But Zack? He literally can’t die.
The real question isn’t “Will he survive?”
It’s:
How many disasters will he cause before reaching the Demon King?

IDIOT IMMORTAL
