Demon, Make a Deal with Me

In a world where everyone has supernatural powers, demons roam freely, and ancient gods wreak havoc, how is someone from Earth who has just transmigrated here supposed to protect himself?

You're an esper?

Sorry, my power lets me see your abilities. I can see right through you.

You're a demon?

Sorry, my power can strip you of your authority. In front of me, you're no better than a child.

You're an ancient god?

Well, sorry about that too. My power can solve your sleep problems once and for all, provided I can trap you inside a marble.

Everyone fears demons and keeps their distance. Only deranged believers make deals with them, hoping to gain uncanny powers.

But I'm hoping a brave demon will come along and agree to a little deal with me.
