Yume (夢) follows the story of Yorishiro, a man haunted by the fragmented memories of a past love named Yume, whose sudden disappearance has left a profound emptiness in his life. Desperate to understand what happened to her—and perhaps to himself—he seeks the help of Doctor Razi, an enigmatic therapist pioneering a technology called the Dream- Machine, a device designed to unlock hidden memories and subconscious truths. Yume explores the fragility of memory, the longing for lost love, and the fine line between reality and dreams in the shadowed alleys of Tokyo.
