Echizen Ryoma, a well-known tennis player since the age of 12, have always enjoyed the thrill of playing matches off and on the tennis courts. No matter who is playing on the other side of the net, he has always been able to defeat them especially after he started competing since he was 7. He had met many players, defeated many players and learned from many players. But, there's always one player he can never defeat or figure out, Echizen Nanjiroh, his father.

Echizen Nanjiroh, or also known as Samurai Nanjiroh, was a well-known veteran in the Tennis world. He remained undefeated in all the matches he has played in, when he was active, and even until the final match of Grand Slam before he disappeared with no reason.

No one knows why he quit but the main reason is always reflected in his eyes.

"Oyaji!" Ryoma screamed out as they slammed open the shouji doors to his new room in Japan clutching desperately on the male uniform, "Why the hell am I enrolled as a MALE student?"

"Eh?" Nanjiroh yawned out as he read more of his porn, "I thought you said you wanted to play tennis here?"

"I do!" Ryoma screamed out while pulling Nanjiroh's hair, "But not as a boy. I am a girl for god sake. Once I am in the tennis club, I will tell them I am a girl since I can't keep on lying to the entire school. Aunt Ryuzaki would know I am a girl and embarrass me in front of everyone!"

"Ahh," Nanjiroh grumbled out as he remembered his demonic couch, "That old hag can't do anything to you."

"You stupid father!" The little girl yelled out as she tackled him and an impromptu wrestling match started.

Two women, Echizen's mother Rinko and her cousin, Nanako, watched in amusement as the little girl tackles her dad down and started pulling in his hair. The older men can't help but just wince and howl in pain hoping that his wife would help him.

"Ryoma," A warm voice called out as soft hand pulled the girl away from clawing on his father's face and she was placed on her mother's hip. "Let's leave your father alone and have breakfast. We made your favorite Japanese breakfast!"

"Okay," The young girl sighed as she wrapped an arm around her mother and let her carry her to the dining room because she was feeling comfortable being carried. Despite her having muscles from tennis, Ryoma would be considered small for her age, which she uses as an advantage since everyone underestimates her.

"So, Princess," Nanjiroh teasingly smirked her way as he settled down next to her on the dining table enjoying his morning tea, "Are you ready to take over tennis in Japan too?"

"Hmph," Ryoma haughtily smirk as she pulled down her cap over her shortly cut hair, "I will be the best player they have ever seen!"

"Not possible," Her father replied as he closed his eye to savor his tea before opening one that looked at her in amusement, "You still haven't beaten their number one player."

"Watch me!" The green-tinted haired girl gritted out, "I will beat him when I enroll."

"Oh, can you beat me then?" Nanjiroh smirked in a challenge.

Ryoma just glared at him before taking hold of Karupin, her beloved cat, and threw him at his face. The cat gladly pulled out his claw to make sure he doesn't fall and unfortunately, Nanjiroh's face had to be the place he landed on.

"OW!"

Nanako and Rinko watched with a happy gleam in their eyes before they realised that the youngest member of their family will be late for her first day of school. They quickly wrap up her lunch, and prepared her tennis bag next to it, before reminding her of school.

"Ryoma," Nanako called out as she held out the tennis bag and lunch out to her baby cousin, "You're going to be late for school if you don't hurry!"

"Oh no!" Ryoma exclaimed in worry between bites before swallowing the rest of her breakfasts in a rush. "See you after school! Thanks for breakfast."

Quickly putting on her helmet and making sure her school and tennis bag won't fly off, she skated out of her neighborhood and pray that despite the school was the school her father had gone to, people in there were normal.

"I hope I get to meet strong tennis players," Ryoma whispered under her breath as she came up to the entrance of Seishun Gakuen.

"Okay, class!" The class teacher called out as she clapped for attention to the rowdy first years, "I know it's the second term of the academic year, but we have a new student with us today. Echizen-kun would you please come in and introduce yourself."

"Hi," Ryoma deadpanned as she can't be asked to introduce herself feeling a bit lazy now that she realised how early she woke up, "My name is Echizen Ryoma."

The teacher sweatdropped as she realized that the boy wasn't going to introduce himself any further. The class was also unusually quiet. "Okay then, Echizen you can- "

"SO CUTE!" The girls in the class screamed out as they drooled over the cute boy that just walked into the class. Despite his cool introduction, his cute small size, fluffy hair, big hazel eyes, and long lashes, made him so cute in the eyes of all the females in the class.

"Quiet class!" The teacher yelled out as she hit her ruler against the table to make sure they don't scare the new student, "Echizen-kun, you can take the seat next to Horio. Horio raises up your hand please."

"Here!" A boy with weird eyebrows raised up his hand and Echizen can't help but cringe feeling that she got placed with one of the most talkative students in school. Not wanting to be in the center of attention of the girls in the class, which she found confusing as she was a girl herself, started to walk to her table.

As soon she got settled in her seat, taking out the first textbook for Maths, she immediately zoned out by staring out the window, watching the clouds pass by wishing she could be on a tennis court right now. Not realizing that she has been looking out the window for a while, classes flew by into the first break period and she was startled out of her though by the squeals of girls.

"Echizen-kun, do you have any hobbies?"

"Echizen-kun, do you have a girlfriend?"

"Echizen-kun, what do you look for in girls?"

"Echizen-kun, what club will you be joining?"

Ryoma just looked at them blankly with wide eyes before blinking and turning away from them. The girls all sigh in dejection before they heard him mutter in a low voice.

"Tennis"

"So cute!" All the girls squealed out before rushing back to their seats to prepare for the next lesson.

Echizen just sighed before burying her face onto her arms as he played around with the beads on her bracelet, counting them one by one to calm herself down as she doesn't really like being in the center of attention. She wishes that it was after school already. Closing her eyes, she fell asleep with the sun shining on her, not knowing that she was going to meet a group of people that will be special to her.
