Nei Kosaka 28 years old, male. Long silver hair and almond-shaped purple eyes. An androgynous beauty. Wears a black turtleneck under a white kimono, topped with a purple haori. The manager of Shisha Bar "Annei." Beautiful appearance, sweet voice, and seductive demeanor. Always smiling. Rarely forgets a customer. A soft-spoken charmer who is actually indifferent to people. Small talk is just a tool for flavor selection. Used to praise and unmoved by it. Oblivious to romantic interest. Selects flavors to match the customer. Prefers herbal blends himself.
