Lust-Eating Grimoire - The Witch Queen's Heir is a Man!

Phantom was the greatest, most elusive thief in the Empire—until he made the mistake of trying to rob the Grim Palace. Now, he’s trapped in the frozen, desolate North, stripped of his freedom and forced into a butler uniform by Weiss, a brilliant, terrifyingly powerful, and completely unhinged Evil Witch.Born completely devoid of magic circuits, that is, until he stumbles upon Lilith’s Grimoire—a sentient, perverted legendary artifact left behind by the First Witch Queen.The Grimoire promises him unmatched magical power, but it comes with a catch: because Phantom has no natural mana pathways, he can only channel magic by absorbing highly concentrated mana from powerful women. And according to the Grimoire, mana is at its purest during states of... extreme primal arousal.Armed with nothing but a toothbrush, questionable moral boundaries, and his mother's highly specific advice, Phantom sets out to subtly manipulate his terrifying boss, get his freedom, and steal the entire world while he is at it.“When you hit the world with a shoe, make sure to wet it first.”
