"Come on, eat as much as you want, heeheehee..." Touko is remarrying Koji, who was the manager of the store where she worked part-time. Touko was nervous when she first met Koji's son, Hanzo, but was shocked. Although he was Koji's son, he was a handsome, muscular, and attractive male. Touko loved Koji, but he was getting older and could not satisfy Touko's vigorous energy. At that time, Touko could not resist meeting this manly man and ordered an aphrodisiac online. (Of course, it is shipped the same day and free of charge.) Then, one day, after repeatedly giving him the aphrodisiac, Hanzo finally awakened into a monster beyond the realm of a human.
