With his sole purpose fulfilled and no remaining attachments to the living world, he chooses to end his own life, believing his journey has reached its definitive conclusion. However, death does not bring the oblivion he sought; instead, he awakens in a mysterious otherworld that serves as a sanctuary exclusively for those burdened by tragic pasts. Though initially disoriented by this unexpected reincarnation, Kurono soon grasps the possibility that his beloved sister may have also been drawn to this realm after her untimely death. This realization reignites a flicker of hope within his despondent heart, transforming his resignation into a new, desperate mission. Driven by a complex mixture of grief, lingering guilt, and fragile optimism, he embarks on a quest across this strange land to find her once more. His second life thus becomes a poignant journey of redemption and discovery, where the search for his sister offers a chance to heal the wounds that vengeance could never mend.
