"Hurry, hurry! Call a doctor, her water bag is bursting."

"Yes, sir."

That's what Illumi heard when he'd just arrived at the house. Everyone was panicking and his father Silva was ordering the butlers to do something about Kikyou, Illumi's mother. He didn't really know why everyone's in a rush, ever since he entered the mansion; everything looks like they're in chaos or something.

"Father, what's going on?" Illumi asked Silva.

"Your mother's about to give birth for your second brother." Silva explained. "Hurry up! Where's the doctor?" Silva yelled on the butler that was making the call.

"He- He's coming, sir. Just wait for a little while."

Silva went upstairs to check on his wife. Kikyou's been panting and a little stressed because she's about to give birth. Silva was trying his best to calm her down and Illumi was just staring at his mother and he was also told to stay out from this.

"Silva!"

"Calm down, Kikyou. The doctor will arrive here soon."

It took a little while for Kikyou to let her baby out but at last they made it. They were happy for the little child, crying on his mother's arms. Illumi was standing beside the bed with his mother on it and he stared at the little baby. He was glad that his new little brother was born but you couldn't see the gladness he had on his face because he's always showing such emotionless face.

"Illumi, meet your new brother." Kikyou smiled as she handed the baby on Illumi's arms.

Illumi held the baby and he saw his little brother sleeping on his arms.

"Kikyou, what name shall we call to our little child?" Silva asked.

"Hmm...I don't know. Let me think,"

"Killua," Illumi said.

"Yes? What is it, Illumi?" Kikyou said.

"His name will be Killua."

"Alright then, he'll be our little Killu." Kikyou grabbed her baby and looked at his sleeping face then he leaned down to her baby and kissed his forehead.

After 1 year, Killua finally turned 1 year old so they wanted to celebrate his birthday and his parents were the ones handling everything for his birthday. Kikyou became pregnant again and she'll bear another child after nine months. Illumi had fun playing with Killua and he's the one who takes care of him every day because he really likes Killua. Whenever he's on a mission, of course some of the butlers were taking care of him but actually Illumi's always excited to go home because he likes to play with Killua.

Right now, Illumi was on his mission because he'll have to assassinate someone. He liked to postpone his mission so that he could be able to celebrate Killua's birthday, but his parents were telling him not to worry about Killua. He had no other choices because ever since he was trained to become an assassin, he promised that he'll do whatever it takes to make the family proud of him. So, there he goes already, still trying to hide somewhere for a perfect timing to kill his own target.

This is quite hard because even when he's hiding his presence, his target could somehow feel like there's someone following her because she keeps looking back. Illumi's target was a teenager girl and she looks so innocent and nervous. For Illumi, even if that person he should kill is innocent or maybe didn't do anything, he shows no mercy for anyone, he just kills them directly because that's what the family trained him for. Illumi followed the girl silently and the girl kept walking forward. Illumi took out the needles from his pocket then he immediately threw it at the girl.

The girl dodged the needles quickly then Illumi showed himself at the girl.

"I knew there was someone following me." The girl spoke.

Illumi quickly dashed to the girl and he was about to thrust her with his hand but she ran quickly and Illumi didn't had the chance to hit her even once. The girl took her gun as her weapon then she started shooting at Illumi. Illumi dodged the bullets then he jumped at the girl and quickly threw needles at her. The girl hadn't dodged that so she collapsed on the ground then Illumi took the gun and shot her so many times until she's finally dead.

Illumi still had another mission and it's starting to get darker already. He actually hoped that he could still go home to celebrate his brother's birthday but now's not the time for him to think about it because he should hurry and search for his next target.

After he already completed his mission and killed five targets, it's already time for him to go home he was walking, he saw a small gift store then he thought about something. When he entered the store, he saw different kinds of things as gifts for someone.

"Good evening, sir." A woman greeted him.

Illumi didn't reply but he kept looking for something as a gift for his little brother. He saw a bear stuffed toy then he walked closer to it and stared at it for a little while.

"Have you picked something you liked, sir?" The woman smirked.

"How much is this?" Illumi asked, pointing at the stuffed toy.

"Umm... That'll be 1000 jenny, sir."

"Alright, I'll buy this one."

After Illumi paid for the stuffed toy, he wrapped it on a gift wrapper then he rode on a bus for him to go home already. His mission was on a far place so it'll probably take hours for him to reach his home.

He got home after 3 hours and the time was already 3:00 in the morning. When he entered the house, he saw inside his room that the lights are still on. Killua was actually sleeping on Illumi's room but anyway, he could also hear his brother's cry. There was a butler named Goto who's trying to comfort the baby and calm him down but it's no use because Killua's been crying and he won't stop.

"What's going on?" Illumi said.

"Ah, Illumi-sama! You're finally home."

"Why is he crying?" Illumi asked.

"Well, he won't stop crying, I don't know why. He doesn't want to be fed and there's nothing on his diapers, but he's just crying." Goto explained. "Killua-sama, please stop crying."

"Waaahhhh!"

"That's alright, I'll handle him. You could go now, Goto."

"A- Are you sure you could handle him, Illumi-sama?" Goto questioned.

"Yes,"

"Understood, Illumi-sama."

As Goto walked out and closed the door, Illumi took his brother then he tried to keep him quiet.

"Killu, please stop crying." Illumi said. "Onii-chan is already here. Onii-chan bought you something for your birthday."

Killua stopped crying then he opened his eyes then his blue eyes stared at his big brother. Killua smiled as he saw his big brother then his little hands touched Illumi's face.

"Happy birthday, Killu. Look, here's what I got for your birthday."

Illumi showed him the stuffed toy then he gave it to his little brother.

After a little while when Illumi had let his little brother sleep, he placed him on his little bed and his brother was even hugging and cherishing his stuffed toy. Killua snored so cutely and he's even sucking his little thumb, then after that, Illumi switched off the lights and lied down on his bed then closed his eyes for him to sleep because he's really tired on his mission for the whole day.

So, I wrote a Killumi story. I really love that pair so much! It's been enjoyable to write something about those brothers.

Next, there'll be another chapter, so please review if you want me to continue!
