Summary: Kuroko Tetsuya had a mysterious double life that no one knew about. Not Kagami, not The Generation of Miracles. He kept it a secret to protect them and not get anyone else involved, but now that other life is now threatening Kuroko's basketball and all that he holds dear. His worried friends soon find out and no matter how he tries to keep them out, they barged into his other world anyway.

Chapter 1:

Kuroko was in the middle of his fifth period class when he felt his cell phone vibrate. He checked his phone and it was a message from his parents. Kuroko immediately knew something was wrong, his parents would never contact him during school unless it was an emergency. After he read the message, he shoved all of his belongings into his bag and ran out of the classroom. It took a few minutes for the teacher to figure out who left.

Kagami was curious as to why his honor student friend would suddenly ditch class and not even bother to explain anything to him. He was about to follow but he felt his phone vibrating in his pocket and it was a message from Kuroko.

It read:

Sorry Kagami-kun, something important came up at home, please apologize to sensei for me and tell coach and the senpais that I won't be at practice today. I'll do double menu tomorrow.

End

Kagami raised his hand to tell the teacher what had happened to Kuroko. The class went by while Kagami was thinking and worrying over his friend's disappearance. The rest of his day went by the same way and he didn't notice that it was already after school and he was late for practice. He ran as fast as he could to the gym to avoid having an even tougher menu then he was already going to get.

After school coach was going on a rampage because Kagami was late and Kuroko was nowhere to be found, as soon as Kagami opened the door to the gym, he got smacked in the face by coach's fan of death.

"Bakagami! Where were you! You're late to practice and where's Kuroko-kun?! Didn't he come with you?"

Rubbing his now throbbing head Kagami said

"OUCH! What was that for coach!? I was only late a few minutes! And it's not even my fault! Its Kuroko's fault for distracting me by suddenly disappearing in fifth period! Oh yeah, he also said that he won't be able to come to practice today and that he'll do double menu tomorrow to make up for it."

Riko was about to hit Kagami again just because she was still pissed but Hyuuga interjected,

"Okay fine. Do you know what happened? It surprising that Kuroko-kun would just ditch class like that. It's not like him, it must have been one hell of an emergency."

"No, the message he sent me didn't say anything else besides it being an issue at home. Come to think of it, Kuroko's never mentioned anything about his family, I've been to his house a couple of times but his parents were never home."

"Okay, we'll find out about it tomorrow then." Hyuuga said to them.

Phweet!

"Enough chitchat! Get back to practice! 5 laps around the gym! NOW! 8 for you Kagami!"

"YES COACH!"

And Seirin's basketball team resumed practice.

Kuroko had sprinted as fast as he could out of the classroom to get to his parents foster home. Something had happened to his parents and he was told to go protect the children. He had no idea what has happened to his parents but he was planning to find out.

Kuroko burst through the front door of the large home to find 8 cowering children with tear streaked faces huddled together in the center of the living room staring at him. After a few seconds, the children got over the shock that someone had appeared and recognized their Kuroko/Tetsuya – onii-chan and ran to hug him. They all started crying again.

Kuroko closed the door and brought the crying children that were clinging to him inside. After calming them down he asked the group,

"Are you all okay? Is anyone hurt?"

He began to look over them for injuries, and was relieved to find none. He stopped being tensed and began to regain his composure from the previous panic.

"Do you guys want some warm milk? It will make you feel better." They all nodded and waited as Kuroko went into the kitchen to fetch the warm milk. When he came back, and they all had drank their milk he asked them what happened.

Rima, one of the children sitting in the group replied first

"A group of scary men came in and yelled at mama and papa! They had guns and were waving them everywhere! Mama and papa told Kanade-sensei to bring us into Kyo's room. She told us to stay there until it was quiet outside and to wait for Onii-chan to come get us. Onii-chan, I was so scared!" She got scared again and started crying. Kuroko pulled her close and hugged her to comfort her. He gently stroked her head to calm her down.

"What happened after that? Do you know?"

This time one of the boys in the group answered

"We heard a lot of yelling from the scary men and the door slammed shut after. When it was quiet, we all came out of the room and didn't see anyone…." He sniffled, tears forming in his eyes.

"Tetsuya- nii, where are mama and papa? Are they gonna be okay?" a small boy clung to his arm and buried his face into Kuroko's sleeve.

The other children sniffled and crowded around their onii-chan for comfort. Kuroko hugged them all close and gently whispered

"Don't worry, your onii-chan will find mama and papa and bring them back, I promise. They will be safe and sound."

Kuroko soon put them all to bed, they had been through a rough day, all of them were exhausted. He took this chance to run back to his apartment near Seirin to pick up a few of his things for an overnight stay.

They next morning, Kuroko woke up early to take care of some things. He cleaned up around the living room and found a letter in an envelope with no name or address. He put it away to read later. He knew it was important. His first call was to Kanade Akane's home to make sure she was safe and to tell her that she is on paid leave until his parents come back and the foster home is in order again. His second call was to Kagami.

"Oi Kuroko, is everything okay? What happened?"

"Good morning Kagami-kun. Yes everything is fine, nothing major, my parents just had to go out of town for an emergency relating to my relatives in another country and it was sudden so they called me to go take care of my siblings since they weren't able to find a baby sitter on such short notice. Also, I won't be going to school for a few days, but I'll be at practice."

"I didn't know you had siblings! How many do you have?" Kagami imagined cute mini Kurokos waddling around and he blushed slightly thinking of how much cuter his partner would look as a chibi.

"8"

Kagami choked on the water he was drinking, "WHAT?! Dang Kuroko!"

"They are adopted, my parents own a foster home other than the apartment I live in. They come home occasionally but mostly live at the foster home with my siblings. I visit them almost every day after practice and Maji Burger."

"Oh. Well tell me if you need help with anything then Kuroko. See you at practice."

Click. Kuroko shut his cell phone. He'll put off making the third call he gets the kids washed up and they all had some breakfast.

"Tetsuya- nii I want pancakes!"

"I want scrambled eggs!"

"Waffles!"

The 8 little kids shouted what they wanted to eat excitedly while getting into their seats at the kitchen table.

"Sorry guys, I'm not really good at cooking and the only thing I can make is boiled eggs. So we'll be having cereal today." Although he said it with his ultra monotone voice and blank face, the kids knew their nii-chan truly was sorry.

"Awww okay." They all ate their cereal in silence until the boy named Sion asked

"So what are we gonna do? Don't you have school today nii-chan?"

Silence….

"Well, I took the day off. After we finish breakfast, I want all of you to pack your clothes and things. We are going to move into my apartment for now."

The little kids dumped their empty bowls and spoons into the sink and ran to their rooms to pack their stuff.

"Don't forget your toothbrushes and toothpaste!" Kuroko yelled after them, although it sounded only slightly louder than his normal voice.

After he put away the dishes, he went out onto the back porch took out the letter he found earlier and read the contents. He immediately made a call.

"Yes Tetsuya-sama? Do you need something?"

"My parents have gone missing. The kidnappers left letter. It is a threat to kill my parents if the family does not give up the title of strongest and control over the underworld. I am sure it is a rival clan that wants more power. I'll bring the letter over to the family house and speak to the elders later. For now, I want you to keep an eye on clans that have been acting suspicious, the clan that took my parents may be among them. Thank you Shigetsu-san."

"Understood Tetsuya-sama, I will get to work right away."

Kuroko closed his phone. He may look calm and even peaceful but his hands were clenched and deep in his baby blue eyes fury and malice burned.

He WILL get his parents back. No matter what. And whoever took them will PAY dearly if they are hurt.

He headed back into the house and gathered up the kids. Soon, after everything was ready, he locked the doors and the group of 9 went on their way.

While walking down the street they were stopped many times by different adult to ask why 8 little 4 year olds were walking on their own. Kuroko wasn't noticed even though he was the one leading them. When he greeted the adults they all jumped back in surprise.

"What are you children doing here alone? Where are your parents?"

"Um excuse me, I am their guardian, Kuroko Tetsuya, How are you?"

"Uwaa! Where did you come from!? What are you doing leaving these kids alone! And why aren't you in school?!"

"I've been here all along, I never left them, you just didn't notice me. And I have taken the day off due to family problems, now if you would please excuse us, we have to go."

Kuroko bowed and left, the 8 little kids following him like baby ducks following their mother. The adults squealed and blushed at the cute sight.

"It's so rare to find such a polite young boy nowadays! Not to mention cute!"

Kuroko decided to stop at the Maji Burger by his house to buy lunch since he had no food in his house besides ramen and eggs, not really healthy for kids.

"Welcome! How may I help you? Awww you little kids are so cute! Are you going on an adventure? Where's your guardian?" the girl at the cashier gushed

"Um I'm right here." Kuroko waved to the girl

"Kyaa! Were you there the whole time?"

"Yup, Nii-chan was standing right in front of you and you didn't notice him onee-san, how silly." The kids giggled and smiled up at her.

"I'm so sorry! How may I help you today sir?" she addressed Kuroko

"What do you guys wanna eat?"

"Cheese burger! And chocolate milkshake please!"

"Me too!"

"Same for me please nii-chan"

"I want a Teriyaki Burger with apple juice."

"Cheese Burger with a strawberry Milkshake for me!"

"Me too! I want the same as Ami!"

"Can I have a barbeque chicken sandwich and apple juice?"

Kuroko felt a tug on his pants and looked down at the small boy with maroon hair that tugged on his pants.

"What do you want Taiga?"

"Can I have a Vanilla Milkshake?"

"Is that all you want Taiga? Are you sure? If you don't eat more, you wont grow tall enough to play basketball with nii-chan."

"Okay I'll eat a cheese Burger too."

"Seven Cheese burgers, one Barbeque Chicken sandwiche, one Teriyaki burger, three Chocolate milkshakes, two Strawberry milkshakes, two Apple juices, and two Vanilla milkshakes to go please."

"That would be 4798 yen please."

Kuroko took out his wallet and paid the girl. He took the kids to a large booth to sit and wait for their order.

"Hey nii-chan, is your apartment big?"

"Yes Kyo, that's why we are all going to live together."

"Yay! Can I share a room with you nii-chan?"

"Hey no fair! I want to share a room with nii-chan too!"

"No I'm the one that's gonna share a room with Tetsuya-nii!"

All of the kids started bickering about who gets to share a room with Kuroko. He sighed. Kuroko felt something crawl onto his lap and looked down to see a maroon hair boy sitting in his lap contentedly.

"Uwa! While we were fighting, Taiga-kun snuck away and sat on Tetsu-nii's lap!"

The kids all looked over at the boy. Immediately another fight broke out among them about who got to sit on Kuroko's lap. They pushed and pulled and shoved each other so they could be the one to sit on their onii-chan's lap.

"Hey now guys, calm down. Sit properly in your seats. I won't let anyone sit on my lap because you guys are fighting. Now wait here. I'm going to pick up the food."

Kuroko left them sitting and went to get the tray. As soon as he turned his back they started bickering again.

"It's all your fault I don't get to sit with nii-chan!"

The other customers in the restaurant and the employees giggled at the adorable sight. Some even took out their phones to take pictures of the family.

"Alright, I'm back. Here are your drinks, can you hold them by yourselves?"

"Yup!" they chorused. He passed out their drinks and they eagerly began sipping them.

"Okay, let's get going now. We are almost at my apartment."

They left Maji Burger and went on their way.

Once again the occasionally got stopped and questioned by various adults because Kuroko wasn't noticed but they got home to the apartment without much trouble.

"Tadaima."

"Tadaima!" the kids said, and they ran into the home ahead of Kuroko who bent down to scratch Nigou's head and ears.

"I'm back Nigou, thanks for taking care of the house for me."

"Arf!"

The kids finished exploring, and had dumped their bags and backpacks in what they found was Kuroko's room and ran out to the living room again. They finally noticed Nigou and crowded around him, petting him and taking turns hugging him.

"You have a puppy Nii-chan?"

"He's so cute! Isn't he Kamiko-chan?"

Kamiko stroked Nigou gently and smiled "Yes he is Ami!"

"Hey I wanna hold him! Let me have a turn Kamiko!"

"Here Aoi. Don't drop him!"

"Wahh! He's so soft!"

"Nii-chan, what's his name?"

"He's called Nigou."

"Nii-chan! He looks like you! Is that why?"

"What? Let me see Aoi!"

"He does!"

"Yes, now that's enough, we should start unpacking your things. When we are done, I'll tak you guys to my school to meet my friends, okay?"

"Yay! We are going to nii-chan's highschool! Hurry up guys!"

"Wait for us Kyo-kun!" And they sped off to Kuroko's room.

For the next hour Kuroko was busy putting the kids' stuff away in the spare dressers that were in the two guest rooms and his parent's room and figuring out how he was to sleep in the same bed as the kids since they all demanded to sleep together with him. He decided he was going to bring one of the queen sized beds from the guest rooms and push it next to the king sized bed in his parents room. He made a mental note to ask Kagami-kun to come over and help after practice. After they ate their late lunch, Kuroko checked the time and as it was close to the time Seirin got out, he announced they will be going to his school.
