[Airandou] Imouto to Nori de Vacance ni Kita Ken

Hina arrives at a seaside resort with her brother, turning a bright summer outing into an uneasy game of private feelings and family boundaries. The story moves from playful beach banter and a bikini-clad introduction to increasingly intimate late-night conversations, where awkward attraction and reluctant honesty sharpen the tension between them. Stark monochrome linework, dense sound effects, and rough English dialogue give the multipanel sequence a candid, confessional atmosphere.
