Born of an Incubus clan, Tsukiya has had enough of the pain that comes from only bringing death to the human men he comes to love and so closes his heart, and denies himself from ever again feasting on human souls. Gento, the ever persistent demon that he is, has never been far from Tsukiya's side and has seen him mourn the death of many lovers, never understanding why Tsukiya continued to seek a love with these mortals that would forever bring him nothing but pain. Now years later can Gento, still ever pursuing Tsukiya, finally win over Tsukiya's heart for himself, and can Tsukiya help a young Incubus through the pain that comes from falling in love?
