Токкэби мечтает избавиться от своего бессмертия и обрести покой. Его мучают воспоминания о человеческой жизни 900 лет назад, о несчастливой судьбе: долг, верность, сражения, реки крови, предательство, смерть родных людей, его смерть от собственного меча и проклятие, положившее начало бесконечному одиночеству. Чтобы снять проклятие, токкэби нужна невеста из простых смертных, девушка с особенным даром. Он в вечном поиске и разочаровании.
   Жнец смерти - пунктуальный трудоголик, одержимый незавершенной миссией найти потерявшуюся много лет назад душу человека, не пожелавшего умирать.
По воле случая две мощные силы, токкэби и жнец, оказываются под одной крышей, теперь они соседи, которые не переваривают друг друга. Когда выясняется, что предмет их поиска - одна и та же девушка, события принимают еще более непредсказуемый оборот...
