Welcome to Demon School! Iruma-kun Universe

As a normal human, if you fall into the demon realm and aren't careful about what you eat, you'll lose your life in no time.

Most meat in the demon realm is harmful to humans, aside from its extremely pure protein and fat. Eat the wrong thing, and you're dead.

Most vegetables in the demon realm contain substances that are harmful to humans, aside from the perfectly normal dietary fiber, vitamins, and plant protein. The trace elements that benefit demons are all harmful to humans. Eat the wrong thing, and you're dead.

Most water in the demon realm is poisonous to humans because of its magical properties. Only mountain spring water containing minerals and pure distilled water without anything in it are safe. Drink the wrong thing, and you're dead.

What? You say Iruma is human, too, and he's eaten all kinds of things in the demon realm without anything happening to him, and he's still in great shape?

Have you never read the manga? Don't you know he's destined to become the Demon King? Can a human who can become the Demon King of the demon realm really be called a normal human?

Of course normal people die if they eat the wrong thing! Otherwise, why would they need to stay alive by eating candy?

Actually, this is the story of a witch with some angel blood who accidentally falls into the demon realm and struggles to survive.

I mainly just want to fill out the world of Iruma-kun. Everything here is my own invention, though some of the settings are based on The Great Demon King. Updates whenever inspiration strikes.
