Airisu Sakura

Biodata

Background / History

Airisu Sakura is a student in Class D who is initially introduced as an extremely shy, timid girl with social anxiety who prefers to shrink into her own safe zone and avoid attention 6. She sits next to Beihai, who initially approaches her as part of his strategy to blend into the class and form a low-profile social circle 6 7. Though initially terrified and awkward during their early interactions, she gradually opens up to Beihai through ongoing contact, shared snacks, and mutual support 6 30.

Beyond her quiet school persona, Sakura harbors a secret: she works as an underground idol on the internet, taking bold fan-service photos and singing online 36. She constantly worries about her secret being discovered, fearing peer judgment 36. When a middle-aged stalker obsessed with her begins targeting her, Beihai and her peers intervene to protect her, leading to the stalker's downfall and a subsequent payout of mental distress compensation 40 44 45. Through these events, and with Beihai's reassuring handling of her secret, Sakura slowly gains confidence and grows more comfortable interacting with others 45.
