Airi Sakura is a first-year student at the Advanced Nurturing High School. With her waist-length pink hair tied in low twin pigtails and swept bangs, she has an extremely well-endowed figure that rivals that of Honami Ichinose. However, unlike her confident peer, Airi is painfully shy and prefers to stay in the background. She often speaks in a soft voice and avoids eye contact. Despite her social anxiety, she has a keen ability to read others, noticing details that most miss. In her free time, she enjoys taking self-portraits, posting them online under an alias to receive praise from strangers—a comfort she lacks in real life.
