In A Different World

Ch 1 A Threat

A man in his early 30's with jet black hair and thoughtful brown eyes was thinking. Earlier that day his wife had come to him with a proposal. "I think its time for our boys to begin their training Yoshi," a beautiful women with long silky black hair and kind black eyes said to her husband.

"They are still very young Shen," Hamato Yoshi said, looking at his four young sons, who were playing off to the side.

"Yes I know this," Tang Shen said with a smile. "But did you not tell me that you were just five years old when you began your training?"

"Yes this is true," Yoshi said with a smile of his own. "But Michelangelo and Donatello are only four and three. They may not be able to do as much as Leonardo and Raphael."

"Donatello has always been very quick to learn," Shen pointed out. "He is very bright. And I am certain Michelangelo will follow his older brothers' leads. They will be fine Yoshi."

"Very well," Yoshi said with a nod. "Then I shall begin their training at once." Shen smiled, grateful that her husband had listened to her.

"Boys!" she called, gaining the attention of her sons. "Please come here. Your father has something very important to tell you." With that the four young boys quickly came up to their parents.

"What is it Mommy?" a young boy with dark brown hair and light brown eyes asked.

"Leonardo would you and your brothers like to begin your training?" Yoshi asked.

"Training?" a second young boy with light brown hair that fell slightly over his forehead and dark brown eyes asked.

"Yes Raphael," Yoshi said with a smile. "I feel you and your brothers are ready."

"Yea!" Leonardo exclaimed, jumping up and down with excitement.

"Finally," Raphael said. "I thought we'd never get to train."

"Hmm I thought you two would be excited," Yoshi said with a smile. Then he looked at his two younger sons, who were looking at him with confusion.

"Donatello," Yoshi said, kneeling down so he was eye level with the two younger boys. "Michelangelo do you understand what's happening?"

"Yes Daddy I do," a young, skinny boy with jet black hair and black eyes said. "I'm just a little scared. What if I'm no good a being a ninja?"

"You never know unless you try my son," Yoshi said with a smile. Donatello smiled back, knowing his father would never lead him wrong.

"Michelangelo," Shen said to her youngest son. "Do you understand what training is honey?"

"Uh huh," a small boy who had light brown hair and light brown eyes said. "It means we're gonna be awesome ninjas like Daddy is! But we gotta work real hard at it. Right Daddy?" Michelangelo looked at his father, who smiled proudly at the three year old.

"That is very good Michelangelo," Yoshi said, picking up his youngest and giving him a hug. Michelangelo giggled and hugged his father's neck.

"Daddy are we gonna train now?" Leonardo asked.

"We better be," Raphael muttered, crossing his arms.

"Shut up Raph," Leonardo hissed, glaring at his twin brother.

"Make me Leo," Raphael hissed back, glaring right back at Leonardo.

"Boys that is enough!" Yoshi said firmly, causing his oldest boys to instantly be quiet. "And to answer your question Leonardo: we will begin training tomorrow morning. Since you, Raphael and Donatello attend school you will do your training before school starts and again after homework is finished. And Michelangelo will be training with me while you are at school." Even though Donatello was a year younger than Leonardo and Raphael he was able to begin Kindergarten with them due to his high IQ.

"Goody I can't wait!" Leonardo exclaimed, unable to contain his excitement.

"Me either!" Michelangelo cried out as he and Leonardo both began to dance happily. It wasn't long before Raphael and Donatello joined in and all four boys were dancing happily. Shen and Yoshi both smiled at the sight. But their happy moment didn't last long. Soon the door burst open and a very unhappy looking man with short black hair and cold black eyes came storming in, followed closely by a young girl with shoulder length black hair and dark brown eyes. When the boys saw the man their eyes went wide and Michelangelo and Donatello quickly ran to their mother, who picked up Michelangelo and pulled Donatello close. Leonardo and Raphael looked at the man with wide eyes and stood behind Yoshi, who was staring at the man with surprise.

"Saki!" Yoshi exclaimed, unable to hide his surprise. "I did not expect to see you here."

"Hello Yoshi," Oroku Saki said coldly. "Shen."

"Hello Saki," Shen said flatly. "Its been quite some time since we saw you." Then she noticed the girl, who was hiding behind Saki. "Hello little one," Shen said with a smile. "And what is your name?"

"Karai," the girl said softly.

"You have a child," Yoshi said to Saki, the surprise once again coming out.

"Yes I have a daughter," Saki confirmed. "Her mother recently died so we decided to come back to where I grew up."

"I am sorry to hear that Saki," Yoshi said, shaking his head sadly. Saki said nothing. Instead he stared at Leonardo and Raphael, who were still behind their father. Then he looked at Donatello and Michelangelo. "I see you and Shen have been very busy," Saki commented.

"Yes we have been," Yoshi said with a nod. "But I have to ask Saki why have you come back? The last time we saw each other was not a pleasant experience."

"Have you come to apologize for the way you behaved?" Shen demanded.

"Shen perhaps we should not have this conversation in front of the little ones," Yoshi suggested.

"Leonardo please take your brothers in the other room and play," Shen said as she put Michelangelo down.

"Ok Mommy," Leonardo said as he took Michelangelo by the hand and went in the other room with Donatello and Raphael right behind him.

"Father may I go with them?" Karai asked, hoping her father would allow her to play.

"Go," was Saki's answer, knowing the conversation he was about to have wasn't going to be pleasant. Karai smiled and quickly ran into the other room to play with the boys. Once the children were gone Saki turned to Yoshi and Shen saying, "I regret nothing I said at your wedding."

"Why am I not surprised?" Shen said, crossing her arms.

"I still love you Shen," Saki declared, taking Shen's hand. Both Shen and Yoshi were shocked at this action. But that shock quickly wore off.

"Saki you are wasting your time if that is the reason you have come back," Shen snapped yanking her hand away. "It is like I said to you a million times before: I love Yoshi. He is my husband and the father of my sons."

"We belong together Shen," Saki protested. "And you told me before you got married that you loved me as well."

"I was confused," Shen declared. "I was scared about getting married. But I was wrong Saki. I never loved you. I am sorry if I mislead you. But you seamed to have moved on. After all you have a daughter now."

"I was never in love with Karai's mother," Saki said. "She knew this when I approached her with the idea of us having a child together. I have always loved you Shen. And I will not stop until you are mine!:

"That is enough Saki!" Yoshi said, getting between his wife and former friend. "I will not allow you to speak to my wife in such a way! If you cannot respect her or myself then I am afraid I am going to have to insist that you leave!"

"This isn't over," Saki declared, his voice low and threatening. "I promise you that. This is far from the end." With that Saki headed towards the other room to collect his daughter.
