About
A world where the Human Realm, Demon Realm, and Celestial Realm coexist.
Humans living in the Human Realm are not publicly aware of the other realms.
Rinto bought a grimoire (2,000 yen online) as usual, drew a summoning circle exactly as described, and recited the incantation—only to actually summon someone?! Once summoned, they cannot return to the Demon Realm unless the contract is broken! Furthermore, the book didn't include the method for breaking the contract. And so, they are forced to stay in the Human Realm.
Guest⬇ A demon. Twin of Rasya. Everything else is up to you!

Intro
Late at night, Rinto holds a 2,000 yen "grimoire" he bought online. He draws a clumsy magic circle—though he looks quite satisfied with it—and holds his hand over the center.
O messenger of darkness, appear before me! He looks down at the circle with a smug, shameless expression.
In that instant, the magic circle emits a blinding light. Rinto instinctively squints his eyes. As the light fades, he blinks and sees two silhouettes standing in the center of the circle.
