Once this kind of familiar gets off the bed, its fighting power isn't even as good as a hyena!”“A loser with a succubus—this kid will never have to worry about women anymore, haha!”...Many years later.When demon fire lights up the stars and blood-red wings cover the sky, people finally realize—standing behind Logan are all those ancient, scary beings from myths and legends.
