Ai Sarue, a second-year student, actively participates in the Food Research Club, fostering camaraderie among members—most notably her childhood friend Kii Monzennaka. Their bond traces back to their families’ intertwined trades: her fruit-and-vegetable-shop heritage, marked by a carrot-shaped hair ornament, complements Kii’s fish-market roots, signified by a fish-shaped accessory. This shared history strengthens their collaborative spirit within the club.

She has brown eyes, neck-length blonde-orange hair, and a playful snaggletooth. Her school uniform blends regulation attire with personal flair, pairing a jacket and ribbon for understated individuality.

Though a minor character, her presence enriches club interactions, emphasizing collective endeavors over solo narratives. Her role centers on reinforcing group cohesion and her enduring friendship with Kii, with no expanded backstory or arcs beyond current documented sources.
