Ichi the Witch, Vol. 1

Ichi is a reclusive hunter who knows nothing of Witches and Majiks, but he does have a particular obsession for hunting anything that exudes bloodlust. When that instinct leads him to interfere in a battle between the great Witch Desscaras and the horrifying King Majik Uroro, against all odds, he acquires the destructive magic of Uroro, making him the only male Witch in the entire world! And not even Desscaras herself is prepared for the absolute headache that wild child Ichi is about to give her.
