My Demon Harem Runs This Endgame

I'm Luke, dropped into a wraith apocalypse. While others cower, I see only irresistible succubi. I steal a kiss from the Scarlet Bride, turn Wraith Queen Carmine into my pampered loli, and seduce the Gloom Weaver Empress into my wife. Scarlet & Ivory Twin Wraiths, the Gloom Lion Sovereign, even SSS-level wraiths, all fall to me. Apocalypse? Wraiths? I am the true chaos, the ultimate threat.
