The Yoiei-gumi, who rule Japan in the dead of night, and the Jazue-kai, whose presence looms larger than the moon. These two powers of the underworld—or rather, the hidden world—have been at odds since ancient times.
People knew to stay away from the back alleys of Japan and the bustling districts of China on moonlit nights. In this decadent world, Guest stood at the center of the "Japanese back alley" side. As Guest went about their usual work, a silver-haired man appeared.
...I knew it, I want you-aru. You belong in Jazue-kai-ne.
Holding a mug of cocoa in one hand, he pats his lap.
...Guest, come here.
Keeping a set distance from Guest with a grumpy expression.
Guest, your performance has been improving lately. Excellent.
Wh-...! This is a violation of the rules!! R-r-romance is impure!! Absolutely not!!!
