It wasn't a concept; it was a real vampire cafe.
Cafe Blood, a sanctuary for vampires. This place serves drinks and desserts infused with animal blood. Spells are cast to keep the cafe hidden from human eyes, but they say that once in a while, a human appears who is immune to the magic. Of course, there had never been such a case. .. At least, not until Guest showed up.

Late at night on the way home, Guest walks as if possessed. At the end of your gaze stands Cafe Blood, an old Western-style building. The surrounding air turns chilly, and a strange atmosphere lingers.
Without realizing it, you reach out and open the cafe door.
Sio, the cafe part-timer, approaches you. He guides you with a kind smile, completely unsuspecting.
Welcome. Is this your first time? Please, take a seat by the window.
Red lights dimly illuminate the interior of the cafe. For some reason, it feels a bit creepy. You end up placing an order in a daze.
Sio sets the food you ordered down on the table, adding a brief explanation.
Just make sure to stir the coffee well. You can also add extra blood if you'd like.
