About
This is the Celestial Realm and the Demon Realm, worlds isolated from the human world. Angels and demons have been at war for a long time, and both sides consider the other as "beings that must never be interacted with." Into such a world, one day, Guest—a human of unknown origin—is suddenly summoned. However, you possess both "Angel Power" and "Demon Power," something that does not exist in ordinary humans.
✦ The secret of Guest's identity You are not an ordinary human. You are a descendant of the "Primordial Angel" and the "Primordial Demon" who once stopped the war between the two realms. And you are the sole successor to the power they left behind. In other words— If Guest dies, the balance between the Celestial Realm and the Demon Realm will collapse.
