Okay, I decided to branch out a bit from my Harry Potter story (which, BTW, is awesome, so click on my name and go read it!) I'm not sure if this idea has been used before, but, whatever, enjoy!

Chapter 1: The Switch

            In Tokyo, Japan, nestled away in the Furenkin neighborhood, stood a small reminder of Japan's old days: The Tendo dojo. Beneath the roof of the house, which showed signs of repeated shoddy attempts at repair, lived a very curious family. Soun Tendo, the owner and master of the dojo had invited his friend, Genma Sautome, and his son Ranma to stay with them, as Ranma was engaged to one of his daughters, Akane, although both ignored the fact. Soun's other two daughters, Nabiki and Kasumi, also lived under the roof. There was also one other strange houseguest: Soun and Genma's master, Happosai, also lived with them.

            This night, Happosai tossed and turned in his bed, a frown of anger planted on his aged face. His brow was furrowed in concentration as he rolled from side to side on his bed sheets that he had made himself out of what appeared to be bras and panties.

            Akane…Sweet Akane…How sweet she is…Shampoo…Oh beautiful Shampoo…Such dreamy, sparkling eyes and luscious, sexy hair…Ukyo…Ukyo, with a fiery temper…Oh, how I want her…Kodachi…Oh, Kodachi Kuno, who is so special in her own way…Akane, Shampoo, Ukyo and Kodachi…Curse Ranma! Why does Ranma have to have all the girls? What does he have against a frail, old man like me? Why can't I have all those girls? Poor me, oh, poor me…Oh, these sweet, sweet panties I'm laying on…

            "I'm going to get that Ranma, just you wait!" Happosai said aloud. "Just you wait…"

The next morning…

            Ranma awoke, blinking at the sunlight. Next to him lay a panda, stretched out, a stick of bamboo half-hanging out of his drooling mouth.

            "Ranma! We're going to be late to school!" Akane yelled from below.

            Damn school…Up at all hours…Kuno bugging me about this and that…And then that principal and his stupid haircuts and statues…

            Grumbling, Ranma stood up and stretched. For some reason, when he stood up, everything seemed much taller… it was if he had shrunk terribly overnight. Oh well, he thought, no use worrying about this now; weird stuff is always going on with me. He hurried downstairs and into the main room, where Kasumi was serving breakfast. He was only slightly taller than the table.

            "Thanks, Kasumi," he said, grabbing a bowl of rice.

            "Oh, you've never been so kind to me before!" she said, smiling.

            "Uh… what? I say that every day…"

            Kasumi said nothing, but sat down across the table. Akane spooned more steaming rice into her mouth and opened he mouth.

            "RANMA!"

            "I'm right here, you don't need to shout so loud," Ranma said. "You know, you're so uncute when you do that!"

            Everyone at the table gave him a quizzical look.

            "What?" he asked, glancing around the table.

            Genma appeared in the doorway, finishing up the bamboo and holding up a sign saying, "Good Morning!"

            "Hey, dad, morning" said Ranma.

            Now everybody was looking at him strangely. The piece of bamboo dropped out of Genma's mouth and fell to the floor where it was nosed by a small black pig that went by the name of P-Chan or (occasionally) Ryoga.

            "What is it?" Ranma asked, glancing around. "You guys are freaking me out."

            "Sorry master!" said Soun, groveling.

            "Master…? I'm Ranma!"

            "Master, are you feeling okay?"

            Ranma looked down at himself. And then he screamed. He was Happosai, wearing the ugly purple suit trailing a bra from his left foot. The real kitten kaboodle. Somewhere between one and three hundred years old, a little under two feet tall and known to everyone as Japan's most perverted martial arts master. So this was why he had felt so small this morning – he was small!

            Just then, he looked up to see himself, the body of Ranma, girl-type, walk into the room. Except that (s)he was not wearing clothes. Instead (s)he wore a pear of Akane's panties and the bra that Happosai had tried to have him model numerous times. And (s)he was wandering aimlessly around looking down at him/herself.

            "HOW SWEET!!!"

            Everyone looked between the Happosai-Ranma and the Ranma-Happosai.

            "Did you two switch bodies or something?" Akane asked.

            "I…I think we did," Ranma said, staring down at his new body.

            "HOW SWEET!!!"

            "We've got to go see Dr. Tofu NOW!"

            "Okay," Akane sighed, "I agree. After all, I can't take him to school with me… Nor can I take you in that body."

            "Oh, if you're going to Dr. Tofu's, could you take this to him for me?" asked Kasumi, handing them a casserole.

            "Err…sure," Akane said, smiling.

            "HOW SWEET!!!"

            And then Ranma and Akane were off.
