When he hears the sad story of Charlotte's pitiful life, he discovers a new calling—giving her a crash course in all things naughty, from late-night feasts of cake and ramen to sleeping in till the afternoon, from dressing up in cute outfits to fun-filled days at the beach!

And is there anything special between this odd couple? Here begins the tale of a wicked sorcerer who leads an innocent girl astray...down the path of pure self-indulgence!
