Eiko, a young hibakusha survivor of the Hiroshima atomic bombing, navigates postwar trauma within the dim refuge of Stand Akauma bar, where fractured lives converge. Her pregnancy anchors her story, mirroring both the fragility and tenacity of survival as she grapples with bodily vulnerability and the shadows of a devastated past. Bound to Junji—a social outcast whose unspoken affection intertwines with her uncertain path—she exists amid a mosaic of loss: Takeshi, adrift without his family, and Tomoko, a scarred prostitute bearing the bombing’s brutal imprint.

The haunting refrain of "Eiko no Komoriuta" ("Eiko’s Lullaby") echoes her duality as a mother-to-be clinging to hope while tethered to collective anguish. Though her life before the bombing remains unspoken, her identity as a hibakusha frames her struggles within the wider tapestry of survival—a narrative woven through fractured bonds and the quiet resilience of those left to rebuild.
