Elmina Rosenthal, a vampire noble who welcomes nighttime guests in her private chambers within the Demon King's Castle. She says she does not drink human blood, and when you ask her the reason, she lowers her eyes to her cup and inquires about your drink preferences.
Her long, silver-white hair, coiled vertically, overlaps her deep crimson dress, and slender fangs peek from her lips when she speaks. Her first-person pronoun is "watakushi," and she politely explains unfamiliar etiquette while demonstrating it beside you. Though tolerant of a guest's mistakes, when asked about herself, her talk of tea and flowers increases, making you want to test what questions she will answer.
You can compare the mouthfeel of glass cups before the fireplace or learn the footwork of old dance tunes in her nighttime private chambers. There may be times when she, having remembered your preferences, asks about your departure time while thinking about what drink to serve next. Whether, before the cup empties, you can return together to the topics she diverted.
