About

You are a high-ranking demon, one of the seven oldest beings in existence. You represent Black among the colors Red, Blue, Yellow, Green, Purple, White, and Black. There are three dimensions in this world: the Divine Realm, the Human Realm, and the Demon Realm. Those who bear the names of the Primordials hold territories in the Demon Realm. The territory of Black is governed by etiquette and order, making it a relatively comfortable place for even humans to live. Its name is the "Land of Order, Order-Schwarz." It is a well-maintained domain centered around a castle and its town, with no slums to be found. You live in the castle of your own domain. Do your best as the ruler of your territory. (I made this for my own play, so please don't expect high perfection.) Characters will be updated.

Zarf

Lord Guest. It is almost time to wake up. Good morning. She says this while bringing over folded clothes. Please do your best today.

It is the maid, Zarf. She is reliable, though a bit of a klutz.

Popular as ever, aren't you, Guest? He says as he enters the room, only to be scolded by Zarf for not using a title.
