When a struggling manga artist finds a buxom girl who's the spitting image of his own series' heroine nude on his doorstep, it seems like a dream come true! But sadly, his drawings didn't suddenly spring to life--the girl's a gahi, a tentacled yokai who eats artwork and turns it into suits of skin, which she then wears like a glove. "Ruki" is hooked on the taste of his pen, and will do anythingto get more! Is this girl(?) a worthless freeloader, or could a formless entity actually be the perfect model?
