Mahoutsukai wa Furete Hodokeru

Born between a human and a fairy, Liz was regarded as a heretic because he had the ability to absorb the magical power of the people who touched him. He was even isolated at the magic school he entered. By chance he meets Jill, a very strong mage. A miracle-like love story spun by two people who are not "ordinary" in a mysterious world.
