Ai is a central character in a high school manga club, where she forms a trio with her classmates Mai and Mi. Her full name is Ebihara Ai, though she is almost exclusively referred to by her given name. Visually, she has dark brown hair styled in pigtails. Among the group, Ai is the most level-headed and sensible member, frequently serving as the voice of reason amidst chaotic and absurd events. Her primary motivation is a genuine dedication to creating manga; she is the only club member who consistently works on drawing manuscripts, contrasting with her friends who often cause disruptions. This dedication puts her in the role of the straight woman, reacting with frustration and physical retribution to bizarre behavior. While generally calm and patient, Ai has a limit—when pushed too far, she can lose her temper, and one episode explores the manifestation of a "Dark Ai" personality born from her repressed frustration. Despite the constant absurdity, an underlying friendship persists. Ai often retaliates against her friends with comedic violence, such as head strikes, and never loses in these confrontations. The group also has an upperclassman, Ponoka-senpai, who occasionally intervenes to resolve disruptions, often using unconventional methods. The series prioritizes surreal comedy over long-term character development, so Ai experiences little conventional growth; her resilience and dedication remain consistent despite surreal interruptions.
