Ranma Half Moon chapter 81 "The Second Mysterious Transfer Student Part One".
Author's note: This episode happens during the Sailor Moon episode 37 "Aim to be a Princess? Usagi's weird training".
A disheveled girl wearing large glasses walks slowly along the street. "I must make it on my own power."
She walks by an expensive-looking school. An elegant lady runs out to meet her. "Miss, miss! I think you could be one of the girls this school is here to find. Girls with the potential to be a princess."
The girl coughs. "That's very nice of you, but ..."
"I am Madam Rose. All you need to do is throw this Frisbee."
The girl looks at Madam Rose with a blank expression. She takes the Frisbee and throws it. It goes all of four feet.
"Oh well, never mind. Have a nice day!" Madam Rose runs off.
The girl looks down. But, I'm a queen, darn it.
...
Ranma-kun and Akane arrive at school. They are very careful with their timing so that they get there before Haruka shows up. That way they can still have a workout by beating up half the student body.
After easily running the gauntlet of those wanting to be Akane's boy friend they arrive at their homeroom class.
"Class, I don't know what seems to be going on, but, again, we have a transfer student. Hopefully, she won't cause as much commotion as Miss Tenou did last week."
The teacher leads in a completely plain, slightly overweight girl with messy hair. She moves slowly and with difficulty.
One of the boys in the front row picks up on this. "Miss, do you need help?"
"No, I must do things on my own if I am to get better."
Another boy in the front row tunes in. "Better? Have you been sick?"
The girl puts her briefcase down and sighs. "I had a heart attack several weeks ago."
"Wahh?" The entire class tunes in.
"They had to revive me with paddles like they do on television."
"Are you okay now?"
"I am strong enough to go to school, but it will be at least six months before I can get back to doing what I love."
One of the boys in the second row nearly falls off his chair. "Oh my god! Oh my god! It's her!"
"Wahh?"
"It is. But, why are you ...?"
The new girl blushes. "That's so nice of you not to say it, but there's no point in not saying it. I've gained twenty pounds. I haven't been able to work out."
"I'm your fan club member one-seventy-five. The newsletter mentioned your recovery and your desire to secretly attend a high school."
The girl pouts and play-punches herself in the head. "I guess the part about it being secret is out the window now, huh?"
"Oh my god! I'm sorry!"
The teacher looks at the student with great interest. "Miss, maybe you should make a proper introduction?"
The new student nods. She writes her name on the board slowly and with effort. "Hello, everyone. My name is Mio Kuroki."
"WHAAAA?"
"Yes, that Mio Kuroki. I hope you all can take care of me so I can regain my health and get back to making everyone happy."
"One-fifty-five!"
"One-twenty-five!"
"One-seventeen!"
"Mio-chan is so happy. I wish I had the energy to truly show it, but inside I am jumping up and down."
"I can carry your books!"
"If you need help with studying ..."
"Everyone here is so wonderful. But, if I am to recover, I must do things on my own power. However, if you guys continue to support me, I'm sure I will be able to make my comeback."
Ranma-kun looks at Mio in amazement. She looks nothing like she did at the formal ball for Princess Diamond.
Mio looks over the class. Her gaze pauses on Haruka as she sees the symbol for Uranus magically radiating from her forehead. But this girl is not the girl I met at the ball. How could this be?
"My goodness, class. Looks like we have a commotion again. Miss, could you please indulge your teacher with a weird question?"
"Sensei, in my line of work you get used to weird questions."
"You're not engaged to Saotome Ranma, are you?"
Ranma-kun shrinks back in his chair. Most of the boys in the class turn around in their chairs and stare at him with homicide in their eyes.
Mio follows their eyes to Ranma-kun. "I have met a Saotome Ranma, but she was a girl."
Ranma-kun forces a blank expression. "Did she have red hair?"
"Yes, she did. She seemed really nice."
The class breathes a sigh of relief.
"That's my cousin. I guess she sure gets around, huh?"
Mio stares at Ranma-kun. She sees no symbol on his forehead. "She sure does."
...
Ranma-kun and Haruka eat lunch on the roof. The members of Haruka's fan club temporarily sit some distance away from them at Haruka's request.
"Looks like you have a rival."
Haruka has an unhappy expression on her face. "Where did you meet Mio?"
"Oh, well, Minako, the girl who I fought with, and I crashed a formal ball looking for the Silver Crystal. It was quite a scene. Before the night was finished, three Sailor Warriors and a Dark Kingdom General had shown up. Minako and I wound up getting attacked by Yoma Monsters as well."
"Why was she there?"
"To give an idol concert."
"And, she just introduced herself to you?"
"She was doing a play with Minako."
"I see. I just find it interesting that she shows up here."
"Because she's stealing your fans?"
"Oh, please. You really think I am that vain?"
...
Outside on the school grounds, Mio eats lunch with her fan club.
Suddenly, their conversation stops as an intimidating figure approaches.
Mio turns around to see a tall student with a practice kendo sword.
"I am Kuno Tatewaki, the Blue Thunder of Furinkan High School. This gathering seems new. What is the meaning of this?"
"Kuno-senpai, we are here to support our new transfer student."
Kuno looks at Mio suspiciously. The atmosphere of the group that he observed seemed out of place for such a plain girl. "So, miss, may I ask your name?"
"Of course, senpai. Mio Kuroki."
Kuno does a double take, then a triple take. "The Mio ..."
"I had a heart attack a little while ago. I gained weight because I couldn't work out."
One of Mio's fans looks at Kuno strange. "This is her fan club meeting. I'm surprised that you've heard of her senpai."
"Number ninety-five."

Special Omake: "The Third Mysterious Transfer Student".
"Class, I don't know what seems to be going on, but, again, we have yet another new transfer student. Hopefully, she won't cause as much commotion as Miss Kuroki did last week."
A disheveled girl in ugly clothes enters. With no warning, the lights dim, as if she was sucking the light out of the room.
The transfer student whispers, "Hello, everyone. My name is Sunako."
"I couldn't hear you, did you say Sadako?"
Sunako turns her head right to look at the student by rotating her head on her neck nearly all the way around to the left. An icy wind blows in the room, and Sunako seems to float over to the offending student. "No, Sunako."
"Sudoku?"
Sunako runs up to the blackboard and draws a four by four grid and inserts numbers from one to four inside the grid, being careful not to put the same number twice in any row, column or two by two sub-grid. "No, Sunako."
"Teacher, she's scary!"
"Now, class, calm down. I'm sure that Sunako is just a normal teenage girl. Sunako, what sorts of things do you like to do in your spare time?"
"Sit in a dark room and watch zombie snuff porn."
The teacher hides behind his desk.
Annoyed, Haruka stands up. "What's wrong with you people. Why are you afraid of someone who is a little bit different?"
Sunako screams and hides behind the desk with the teacher.
Seeing how scared Sunako is, the teacher composes himself. "Miss Sunako, why are you scared?"
"He's one of the bright shiny creatures."
Annoyed, the teacher drags Sunako over to Haruka. "Miss Tenou is a girl."
"Sorry."
