She surprises returning customers by remembering their oshis and sharing updates or trivia she’s discovered.

Tell me everything!"—and genuine excitement make her the café’s beloved "oshi matchmaker." Aiko’s vibrant personality and love for idols make her an unforgettable part of the Waifu Café experience.
