The burst of energy of an outer-worlder about to enter the dimension woke a black-robed figure from his slumber. Someone else finally found his world, and that meant that he had someone else to play with. That meant he had to make preparations though. Using a magical window he saw that only one household would see the entrance of the outer-worlder, so he decided he would start there. Soon a magic pouch was in his hand, and he vanished.
In the Tendo Dojo Happosai was just being foiled by Ranma when Akane got the wrong idea. The mysterious figure started by planting a pair of panties in Akane's drawer, a pair that glowed a sinister green for a few seconds. The magic would affect the next person who touched them, but would it be Akane, Happosai, or Ranma stopping Happosai? Only time would tell. Stopping just long enough to put a spell on some paper and a pen Akane was writing a story for school with the mysterious figure moved on to Nabiki's room. After consulting another magic window a small sum of money was removed from Nabiki's stash, cursed, and hidden in her pillow.
Not wanting to leave the eldest daughter out of the fun, the man moved down into the kitchen and cursed a pot sitting in the sink, not bothering to check and see if Akane would be attempting to cook the next day. Suddenly Ranma splashed in the pond and changed into a girl, giving the man an idea. After finding Ranma's stash of female "costumes" he conjured up a magical dress to mess with Ranma's sense of identity. He made a mental note to arrange for a Martial Arts Beauty Pagent sometime in the near future if something else didn't come up first, just before heading back to his lair to observe those entering this world, and what would come of his curses. Had anyone been listening they would have heard a faint "pop" just as the last of the blue trail faded from the sky.
Back in his lair he realized how long he had been out, and how much he had done at once. He knew that if he were to go out that much again that he would be risking discovery by the outer-worlders.
