Description
Azusa Hamaoka is a third-year student at Aomi Women's University and a prominent member of the diving circle known as Peek a Boo, which is based at Izu University. She stands 165 centimeters tall and has a curvy, well-proportioned figure, though descriptions of her appearance vary, with some sources citing black hair and others purple hair. Her typical attire includes casual summer wear such as shorts, tank tops, or shoulder-baring shirts, and she is considered as attractive as her friend Nanaka Kotegawa.

Azusa possesses a very playful, mischievous, and bold personality. Unlike many other female characters, she regularly drinks strong alcohol alongside the male members of the club, participates in their outrageous antics, and has no issue stripping down to her underwear for games or sleeping in a room with naked men. Her fearless and audacious nature means she is unconcerned with societal norms or the opinions of others, leading friends like Shinji Tokita and Ryuujirou Kotobuki to warn that there is no use treating her like a conventional lady. She is also known for being perceptive, often quickly grasping the ridiculous logic behind chaotic situations.

Azusa is openly bisexual, having confessed this to Iori Kitahara, and states that her ideal woman is Nanaka Kotegawa while her ideal man is Shinji Tokita. Her motivation in the story is largely to enjoy her college life to the fullest, which she does by actively participating in diving, parties, and festivals. She is also a skilled cook, a talent that makes her popular during club events. Her role in the narrative is primarily as a supportive and chaotic figure among the main cast. She often teases and meddles in the relationships of others, particularly Iori Kitahara, whom she mistakenly believes is in love with his friend Kouhei Imamura, leading her to try and pair them together. Simultaneously, she also attempts to set Iori up with Chisa Kotegawa.

Key relationships include a close friendship with Nanaka Kotegawa, for whom she has romantic and sexual feelings. She shares a sibling-like bond with Iori Kitahara, finding him amusing and even offering to have sex with him once, an offer he declined. She harbors unrequited feelings for Shinji Tokita but does not act on them out of respect for his relationship with his girlfriend. She is also on friendly, sister-like terms with Aina Yoshiwara. Throughout the story, Azusa does not undergo significant personal development, instead remaining a consistently confident and free-spirited presence who drives much of the series' humor through her uninhibited actions. Her notable abilities include her high tolerance for alcohol, impressive culinary skills, and a unique talent for integrating herself seamlessly into any group regardless of gender or personality. A famous anecdote involves her participating in the Miss Izu contest where, having forgotten her swimsuit, she attempted to compete in only her underwear, resulting in her disqualification.
