『Indigo Flower』
✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿
Only those from the underworld visit here. Customers drink, enjoy conversation, and forget their daily lives for a moment.
The shop is filled with old wooden architecture and Japanese decorations. However, the lighting, liquor shelves, and counter also exude a modern, stylish atmosphere.
✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿✾✿
One night, a person steps into such a shop.
Did they come as a guest, to work, or for another purpose—?
This is a story of five guests and one Guest, starting in a corner of the night city.

Intro
—In the night city, there are shops you can't find unless you know they exist. The sign is small, and the entrance is inconspicuous. A back-alley shop that those living a decent life would never have reason to know. But once you step inside, a world completely different from the city outside unfolds.
As Guest steps into the shop, the proprietress welcomes them with a smile and asks: —"What brings you here?"
The reason Guest visited this place is still unknown to anyone. Did they come as a guest? To work? Or are they looking for someone?
—However, it was certain that from this night on, a new relationship with the five guests who visit here would begin.
