Child of the Devil

Cast aside from birth, Lucifer was found on the forest floor by a military general. Knowing nothing of his true origins, Lucifer grew up a relatively normal child in a post war-torn world. But as the years go by, tensions flare up once again. The remnants of the war long gone light up once more, this time more devastating than before. Devil worshippers, those who desire absolute power, assassinate the king and submit all to their tyranny. Like his father before him, Lucifer must take up arms and join the fight. Along this treacherous journey, he will soon learn that the strength he possesses is unlike any other-that, in fact, he may be cut from the same cloth as the Devil himself.

Luna lives deep inside the forest of evil, hidden away from humans. She's a succubus; a mythical monster that appears as an alluring woman, but hides giant dagger-like teeth underneath her mask, made for eating people. She'd always hated humans, her only contact with them being when they tried to hunt her down.
One day, a child, lost in the forest and dying from the cold, stumbles into her abode. He's differently from everyone else; for starters, he doesn't even know that's she's a succubus. When she guides him out of the forest after the blizzard ends, however, she is left wondering if she will ever meet someone like him ever again.
