Description
Aina Yoshiwara enters Oumi Women's University as a first-year student, adopting a flashy "Cakey" persona with a blonde wig and heavy makeup to stand out. This backfires, leading to bullying and isolation within her initial tennis club, Tinkerbell. Her true appearance reveals naturally short dark blue hair, purple eyes, and a gentle demeanor. Stress or intoxication triggers her native Kitakyushu dialect. Seeking acceptance, she joins the diving and social club "Peekaboo" after an incident at the Izu Spring Festival where Iori Kitahara and Kouhei Imamura confront Tinkerbell's leader, giving her the courage to leave. Within Peekaboo, she abandons the Cakey identity, forms genuine friendships, and discovers a passion for scuba diving.

Despite the club's rowdy atmosphere of frequent nudity and heavy drinking, Aina often acts as the voice of reason, chastising inappropriate behavior while demonstrating fairness. Key aspects of her personality shift under specific conditions: wearing makeup increases her boldness, while alcohol consumption unleashes a wild, uninhibited side, exemplified by an attempt to remove Iori's underwear during a drunken episode. She harbors secret romantic feelings for Iori, partly due to his role in defending her from bullying. These feelings lead to an unrequited confession. Later, she accepts a romantic confession from Kouhei Imamura after moving on.

Deeply self-conscious about her smaller bust size compared to peers like Nanaka Kotegawa and Azusa Hamaoka, this insecurity manifests as envy and ownership of books focused on bust enhancement. Her background includes assisting her family's business, requiring extensive driving; consequently, she holds an advanced driver's license for manual vehicles, a skill frequently used during club trips. Her development centers on overcoming social anxiety, embracing authenticity, and finding belonging within Peekaboo. She transitions from an isolated outcast to a valued member who balances the group's chaos with grounded pragmatism. While her romantic pursuits face complications, she navigates these challenges while participating in the club's antics. Her journey underscores themes of self-acceptance and supportive friendships, contrasting sharply with her exclusion in Tinkerbell. She remains integral to Peekaboo, contributing practical driving and diving skills while adapting to its unconventional culture.
