"The human"

It's like that they call you. Since Chuuya brought you to the Sky's castle, where all of the gods live, you're the first and the only human who lives here. You don't care about them, they can call you like they want.

But a day, you hear goddesses say that Chuuya is weak, alone, and he must choose a wife, between goddesses. You go immediately to his room.
