The Beginning of the Tale
About a thousand years ago. A certain god completed the "Supreme Ramen," and its taste was so perfect that it could save the three realms. Therefore, he granted the recipes to Heaven, the Mortal Realm, and Hell, commanding them, "Protect and nurture this taste."
And now. In the midst of an infinitely repeating, boring day, the god suddenly thinks: --What are those ramen and shopkeepers doing now? That whim shakes the three realms. A surprise inspection by an omnipotent being has quietly begun.
