Disclaimer: I don't own either Ranma ½ or Ouran High School Host Club. Both are owned by their respective owners.
To say that Ranma was confused would be an understatement. Just 5 days ago he was living with his father and the Tendo in their home and the next thing he knows his mother shows up and somehow found out about his curse and all of the things his father had him do in the name of training. He only was able to find this out when Kasumi explained why his mother was as angry with his father as she yells could be heard from even outside of the Tendo Dojo. They were outside because Nodoka had asked them to wait for her outside as she "talked" with his father. And seeing as how it was a nice day anyway everyone figured why not.
What Ranma would learn during his mother's "talk" was that Nodoka was able to divorce Genma without his signature due to the evidence she was able to gather of his child abuse of Ranma. Not only that but she was apparently from a very wealthy family and was now back in their good standings. While waiting for his mother Nodoka came out of the Tendo Dojo with a packed bag and grabbed Ranma's hand and started leading him to the streets. This is when he learned that he was now going to live with his Mother instead and was also going to be enrolled into a new school. He tried to protest but the look Nodoka gave him left no room for arguments.
He was allowed to stay in contact with Akane, Nabiki and of course Kasumi so that the changes he was going to face wouldn't be that hard. He was also allowed to stay in contact with Ukyo and Shampoo. But everyone was also made clear of one new rule they all must follow if they wanted to stay in contact with Ranma. They were going to be forced to drop their engagements, at the very least until he finishes high school. The Amazons tried to fight this rule but Nodoka had to simply sate one name. A name that only Cologne apparently knew of, this person was someone that Nodoka's family knew very well. And if he was brought into their affairs then the Amazons could be seeing some very bad hardships. As such they agreed as long as long as no one was being favored over anyone else in the engagements. Nodoka insisted that would not be the case and as such Ranma was essentially free of Nerima.
That new school that Ranma was going to? It turns out that it was a school for the very wealthy. Ouran Academy a place that Ranma was being given a tour of at the moment by the head master Yuzuru Suoh. He would have been in the school's uniform but a quick demonstration of his curse, which was suggested by his mother, which caused Yuzuru to learn a few new things. First of which was that curses existed and by extension so did magic. Secondly he was going to have a long day ahead of him convincing the staff to not worry about another student not in the right uniform. The staff of course understood the original reason as to why Haruhi Fujioka wouldn't be in uniform but once she started to wear a men's uniform they started to complain. This was of course stopped by Yuzuru who pointed out that technically there was no real rule stating which uniform a student had to wear. This one was going to be a problem though.
After showing Ranma around a bit Yuzuru and Nodoka left for his office in order to fill out all of the paper work. Nodoka insisted that Ranma should check out the club rooms at least while she was doing this. This is why Ranma was currently in front of music room 3. He heard that some sort of "Host Club" was in there and his curiosity was getting the best of him.
Several girls…okay make that a lot of girls were all that Ranma could see. They all seemed to be talking to one guy or another. One he would have asked if he was really a high school student but Miss Hinako from his old school taught him to not judge people's ages by the way they looked or acted. It didn't take him long to notice that two of the guys were to be twins or at the very least very close in age. Once he started to feel comfortable about the place a voice from behind him asked, "Well this doesn't happen often. A man has walked into the Host Club. And who might you be requesting today?"
Ranma simply blinks in response until someone else gets near to him. Unlike the owner of the voice whom was wearing glasses and had dark colored hair this new person had blond hair and was way too cheerful. And was getting into Ranma's personal space while quickly pissing him off once he saw the way he dressed. Something about the way he said commoner was pissing him off.
"Tamaki senpai would you cut that out! He looks like he is going to strangle you!" a new voice interrupts.
This causes Ranma to tilt his head slightly as this "Tamaki" person was talking to the shorter one. This would have continued had the Twins not join in on Tamaki's questioning and discussion amongst themselves. They were also getting into his personal space and backing him up against something which he could not quite figure out what it was. Haruhi was able to though and yells, "Stop it guys! Or do you want another vase to be broken!"
The twins stop and turn to Haruhi and say, "We didn't break the last one."
This of course irritates Haruhi knowing full well who they felt did break the last one was her. She sighs and turns to Ranma and says, "You know I never seen you before. Who are you? Are you a new student here at Ouran?"
Ranma blinks at the sudden change and answers, "Yeah. My name is Ranma Saotome. And I am the heir to the Anything Goes Dojo of Martial Arts….I normally would say heir but my Mother said that it would sound better than student." Ranma was already scratching the back of his head when he finished his introduction.
