Kuro to Shiro no Koufukuron

Iori Shirase is no ordinary girl. Having inherited a set of mysterious abilities passed down from her grandmother, she carries a unique burden that sets her apart from those around her. Her life takes a meaningful turn when she crosses paths with Tsukasa Kuroe, a solitary and isolated young woman who possesses an extraordinary, natural gift for playing the piano. Alongside Tsukasa is her younger brother, Sousuke, and together the three begin to forge a deep and genuine bond. As their friendship blossoms, they find solace and strength in one another's company, creating a fragile sanctuary away from the hardships of their individual lives. However, the warmth of their growing connection is soon threatened by a dark and encroaching presence. The looming shadow of a dangerous cult—the very same organization that Tsukasa’s mother became entangled with—begins to creep closer to their lives. What starts as a distant concern slowly transforms into an immediate peril, testing the limits of their newfound companionship. As the cult's influence tightens its grip, Iori, Tsukasa, and Sousuke must rely on each other to navigate the escalating danger, fighting to protect both their bond and their futures from a sinister force determined to pull them apart.
