Chapter I

It was a nice morning and our young prodiogy was taking a peaceful nap on the school rooftop when all in a sudden, a hyper red head had to wake him up in a not so nice way :" Ochibi, there you are, we were looking for you" He glomped him.

"Eiji, don't do that, Echizen can't breath" Oishi reminded his double partner.

"Oops, sorry ochibi" He let go of Ryoma

"Thanks Oishi-senpai, but why are you guys looking for me?" Ryoma asked

"Saa, we just want you to have lunch with us, right Tezuka?"Fuji said

"..."The said buchou just nodded

"Yadda, i'm not hungry." He shook his head

"You're always so picky, Echizen, that's why you never grow"Momo complained

"It's not your problem so shut up Momo-senpai" Ryoma groaned

Suddenly, Ryoma felt dizzy, he fainted immediatly. Luckily, Fuji was there to catch him before he hit his face on the ground. This made everyone panicked.

"E-Echizen, why did he fainted,what should we do now."Oishi worrily said

"Come down Oishi, we must take him to the infirmary first" Inui said

_15 minutes later_

After Ryoma was taken to the hospital, the regulars return to there classes with a worried look on there face.

_At the hospital_

"SAY WHAT!" Ryoma and Nanjirou shouted while Rinko and Ryoga looked extremly happy.

"Like I just say, you're not a boy, more clearly, you're a girl" The doctor, Sakimoto, took off his glasses.

"So that means i'll have a little sister/ daughter!"Ryoga and Rinko happily said

"B-But how could this happen?" Nanjirou asked

"Ah, this's because there are occasions when there is a damaged chromesome of some eror in genetic replication. In apperance, some people may be a male to the eye, but they are genetically a female or it could be the opposite" Dr. Sakimoto replied.

"Matte, so in other words, i'm acctualy a..."Ryoma stuttered

"Yes, you are acctualy a girl" Dr. Sakimoto smiled

Finally, Ryoma brain has stopped finction, she fell from her chair and became unconcious immediately.

_20 minutes later_

"Urgh..."Ryoma groaned

"Ah, chibisuke, you're awake" Ryoga smiled

Suddnely, Ryoma grabbed his shirt :"Aniki, please tell me everything was a dream and I'm not a girl"

"Sorry chibisuke, but I can't, it's not a dream."Ryoga shook his head

Once again, Ryoma became unconciouss still holding on to Ryoga's shirt.

_25 minutes later_

"Urgh..." Ryoma groaned again

"Ah, chibisuke, you're awake again"Ryoga said "Now, could you please let go of my shirt"

"Gomenasai aniki."She said

"Ah, honey you're awake" Rinko stepped in the room

"Hai, kaa-san" She replied

"Your father and I have done arranging the papers" Rinko said "You'll be Echizen Ryuuki from now on"

"Matte... I haven't agree with that yet" She shouted

"Don't worry honey, you can still play in the boys tennis team and in tournaments" Rinko smiled

"Well okay, but I don't know anything about being a girl yet"

"We'll go shopping tomorrow to buy you some new clothes, Nanako and I'll teach you how to be a girl so you don't need to worry about this"

"Urgh..."Ryuuki groaned, she had a very bad feeling about this.
