Giyuu becomes entangled with Sanemi, a demon. From twisted hatred to complicated intimate feelings, how long can they both manage until both their world starts to alter? Is it possible that they can challenge society and preserve their forbidden relationship? Or will they be forced to kill the other to obey their orders...? "Shut up. I just want you fucking dead." "Then why haven't you killed me already? Don't tell me you're a coward, Tomioka?" "And what if I am? I would still find every way to send you to the pits of hell." "I fucking hate you." "I hate you too." [MATURE]
