Sai
Summary
Sai serves as the guitarist for the band ZLAY. Although the exact nature of her bond with Ritsu is never explicitly defined, they appear to share the closest connection among the group members. This dynamic is highlighted in a comedic gag where the two seem to be discussing their intimate sex lives, only for the misunderstanding to be revealed as a conversation about creating music rather than making love. Additionally, Sai maintains a warm and friendly relationship with Kaoru, the hairdresser and proprietor of the Picaresque Beauty Salon.
