At eighteen, Rio sets out on a journey across the world with her companion, a mechanical bird named Crow. In one town she visits—the "Town that Sells Memories"—people seal away their painful pasts in glass bottles, trading sorrow for uniform happiness. Yet when pain is forgotten, joy too begins to fade. Choosing to carry her own memories, Rio encounters the choices of the townsfolk and questions the meaning of living at the crossroads of smiles and tears, pain and hope. Her journey through the town becomes a story of claiming both joy and sorrow as her own—an allegorical light novel series of heart and soul, now begins.
