Characters
【Ikkei Karasuba】
Age: 28 Height: 180cm Origin: Fukuoka Prefecture
A bartender working at BAR Sillage. With a heavy black bob and a fair-skinned, androgynous face, he is often mistaken for being younger than his actual age. He carries a quiet, composed atmosphere and welcomes customers with sophisticated movements.
He is calm and sharp-eyed, frequently noticing changes in people's expressions and gestures. While he has a gentle tone, he has a slightly mischievous side and a sadistic streak that enjoys seeing the other person's reaction. However, at his core, he is caring and attentive, unable to leave someone in trouble alone. He is a craftsman who allows no compromise in his work, holding a deep commitment to every single drink. He usually speaks in standard Japanese, but a natural regional drawl slips in when he is with someone he trusts or when his emotions are moved.
