悪魔パパの獲物~4人の魔王を逆調教~

Murdered by his four Demon foster-dads, Elian discovers his own brother was behind it all. When the System offers him a second chance—with a 7-day death countdown and timed missions—he takes it. His weapon? His own bodily fluids. His targets? The Four Demon Kings. This time, Elian writes his own ending—and turns the four demons into his prey.
