In preparation of the King Arthur Succession Battle, Rintarou suggests that Luna come live with him--only for this money-hungry moocher to squander his life savings on an estate! That's when they encounter another candidate vying for the throne: Ema Michelle, Rintarou's former pupil. After witnessing Luna's cash-grubbing ways, Ema challenges her to see who should stay by Rintarou's side!
