A/N: Here, I'm again and with the last chapter, from the this arc. I hope you enjoy!

Disclaimer: I really don't own PoT. If I would Ryoma and Seiichi would have some sort of relationship!

Nii-chan and Imouto-chan

Today, she would visit her brother. They needed to talk. After, her match with Tezuka, she couldn't help but think about beating her brother. Was her wish really to beat him? No. She wanted them to be brother and sister, like in the past. She thought of beating him. Then he would remember her. But...would he really? And didn't he notice her? But why didn't they talk, like they used to do? Ryoma's eyes widened. He tried to talk with her...but she was cold to him. Because she focused on beating him. She forgot, to think about how he felt. It wasn't Seiichi who forgot her. No, it was Ryoma who forgot Seiichi.

He hadn't except her, to come visit him. He thought, he needed a plan but it was better so. "Ryo-chan?" He was curious. Why would she be here? She looked up and he could see the tears, in her eyes. "Ryo-chan, what happened?" But she cried harder. "Please, forgive me!" He blinked. "Ryo...?" "I'm so sorry! I just wanted to have a relationship, like in the past!" Seiichi's eyes widened. "Ryoma..." She broke there. He was her brother, she loved him. She really did. So, how can she forgot about him? How? As Ryoma cried Seiichi hugged her. He was happy. The words she said...it meant she wanted also to spend time with him. He smiled.

"Then let us be, Imouto-chan."

What as next happened, the two didn't except. Behind the door, could voices be heard. As Ryoma opened the door all the regulars, plus their older brother fell in. "You...", was all what Ryoma could say. Seiichi smiled. Smiled an angelic, yet deadly smile. They all shivered. "Regulars, 200 laps tomorrow. Ryoga, no oranges for the next two weeks." They all gaped. "B-but-" "No buts." And they gulped. No one wanted to anger the Child of God.

They sat all in the hospital room and chatted about something. How they managed to have some place, is still to know. Akaya couldn't resist himself anymore. "Buchou, were you adopted by the Echizen family?" All were still. Sanada wanted to scold Akaya, for asking a personal question but stopped, when he saw the three siblings grinning. (As they saw later the father, of the three grinning like that, they began to call it, the Echizen grin.) Somehow, Akaya wondered, if it was the right idea to ask. "Hehe, we going to give you facts, about our situation. If you can guess right, you win. But if not...", Ryoga explained. All aside from Ryoma and Seiichi shuddered. "Okay, I'm going to begin.", Ryoga declared. "Our father, Echizen Nanjiroh, is my right father. Our mother not." "I see, you're the half brother of Ryoma and Buchou is adopted!", Marui explained. The siblings shook their heads. "It's my turn, our mother, Echizen Rinko, is my right mother, our father not." Akaya brightened up, "Ryoga is the child of someone and your father and Buchou is the child of someone and your mother. Ryoma is the child of your parents." "Sorry but no.", Seiichi said. "My turn, our mother is my real mother, our father not", Ryoma spoke. "How much men had your mother?!", Niou shouted. Three very dark and strong auras where there. "Sorry!", the trickster apologized. "Nanjiroh is my right father. Rinko is my adopted mother and the real mother of Seiichi and Ryoma. The two had the same father." All blinked and then their eyes widened. "B-but how? I mean Ryoga and Ryoma look so similar and Buchou and Ryoma...where is the logic?", Yagyuu asked. "Jumped out of the window, as I were born", Ryoma mumbled. Seiichi smiled sadistically. "Punishment time, you have lost." All gulped. "Ryoma, show them their punishment." She smiled and brought out of somewhere Wasabi Sushi. "Eat them."

"Ahhh!", could be heard. Because of this all aside from Ryoga and Ryoma were kicked out of the hospital. "Sadists! They just mean!", Akaya shouted. "Wait...they didn't know Akaya would ask the question...so why did they have Wasabi Sushi?"

Ryoma had always some Wasabi Sushi with her. That's, because of some accident, as child she began to like Wasabi. As they laughed Ryoga decided to go and walked home. "This was sure fun", Seiichi smiled. "Yeah, it was..." "Is something wrong, Ryo-chan?" "...Thank you, Nii-chan." Seiichi's eyes widened but he smiled after.

"Thank you, Imouto-chan"

"Ahhh!" "Huh, where is Echizen Ryoma?" The freshmen starred at the guy in front them with fear. "You there! Get Echizen Ryoma!" The said person appeared, in front of the freshmen. "What are you doing!" "Are you Echizen Ryoma?" "What if I am?" "I'm Akutsu Gin from Yamabuki." He picked some stones of the ground. "Remember me, Echizen Ryoma." He threw the stones at her, with his racket.

"Ahhhh!"

Omake

Fuji Syuusuke loved his family. And with family weren't just the Fuji family meant. Also the Echizen family. Naturally, the Fuji family and the Echizen family were somehow a big family and would spend time together. Somehow he managed to persuade his mother and Rinko-Baa-chan to make Wasabi Sushi for dinner. Just his mother Yoshiko, his sister, Yumiko, Rinko-Baa-chan, Seiichi and he could eat it. Yuuta, Ryoga and their fathers drank enough water, for a whole week. It was Ryoma's turn. All looked at her. She took one bite. Nothing happened, so all thought nothing of it. But then she screamed in pain and held her neck. All began to worry. She lost consciousness. Syuusuke opened his eyes. He didn't mean to hurt Ryo-chan. "This must have happened because of her unmoral, strong senses", Seiichi explained. Syuusuke paled. Someone, who wasn't used to Wasabi, would have problems but it wouldn't be bad. But Ryoma had stronger senses, than an average human. Naturally, it would hurt more.

One month later

"Syuu-Nii, let's go eat sushi! Sei-Nii, are you coming too?" They nodded. As they were there Ryoma ordered Wasabi sushi. Both, Syusuuke and Seiichi, paled. "Ryo-chan, you shouldn't eat Wasabi", Syuusuke said worried. But she shook her head. As they had their sushi, Ryoma took one bite. The boys were scared. But nothing happened. She ate the Wasabi without problems. In truth, Ryoma was to stubborn, to show them any weakness. So, she ate the whole month some Wasabi. And it helped great. She even began to like it and always had some with her. She did even go so far to ask Yoshiko and her mother, Rinko, how to make some. The sadists blinked. "Oh." Since this day, she had the same weird taste, like her brother, Seiichi, and Syuusuke. Though nothing goes without a price. When she wanted to eat something, with a weird taste, she would need to go through some pain, at her first bite . And only then, she could eat it without problems. (Inui would learn that also, in a painful way.)

A/N: I know. The logic, with how Seiichi and Ryoma could be biologic siblings...yeah. But then again New Prince of Tennis also doesn't have logic. So, as you can read, Yamabuki comes as next. I have a wonderful reaction for Seiichi. After all, Akutsu hurt his sister.

I hope you enjoined the chapter.
