Kaullo bend down and touched his toes. He repeated this five times. Today was his first assassination mission, he was a bit nervous. What if he failed? What if his target would be able to escape? And what if he died? Honestly he didn't like the idea of killing someone, but he said nothing about it. Going against his family would lead to a horrible punishment. Something he preferred not to have. Torture training was already enough for him.

Before his mission, Elilou tied his hair in a side ponytail and dressed him in a long-sleeved light green shirt and a frilly blue skirt along with black boots. The maid smiled at her master and patted his head. "Try not to get hurt." she told him.

His lips curled into a smile. "Don't worry Lou-san, Kaullo won't get hurt," He reassured her.

His father, who strangely would go with him to his first kill instead of Illumi, allowed him to say goodbye to Kalluto and Alluka. Unfortunately, he hadn't been able to say goodbye to Killua. When he asked why, he was told that Illumi was giving the boy extra training and that he would probably distract Killua if he was there. 'Aw, I really wanted to say goodbye to Oniisan,' Kaullo thought disappointedly.

"Your target." Silva started with his usual monotone-like voice. "Your target is Harukio Haziki. He has two bodyguards: Blood and Midnight." Kaullo noted that if the bodyguards had names like that, that they would be really strong. "Midnight is able to use Nen, but he's an amateur. Even so, it would be wise if you don't fight him."

Kaullo nodded. He just started his Nen training a month ago and he still had some trouble with mastering the basics. Engaging into a battle with someone who was already experienced in using Nen would be stupid.

"I'm waiting here for your return," Silva finished.

"Hai, father." Kaullo said and left when the limousine his target rode arrived. He bit his lip and walked into the hotel his target would be in. 'It would be smart to memorize all possible escape routes before killing that man,' He thought.

The lady behind the counter noticed him and asked, "May I help you, little girl?"

Kaullo looked up and tried to smile as cute as possible. "Mommy and daddy …." He wiped away fake tears from his eyes. "They told me to stay in my room….But I forgot where the room is…"

When the woman gave him a sympathetic look, Kaullo felt lower than dirt. Killers don't feel guilty, focus Kaullo!

"Aw, poor thing. Can you tell me your name and who your parents are, sweetheart?" the woman asked. She moved to kneel beside him and smiled warmly at him. "Don't worry, I help you. Don't cry." She wiped the tears streaming down his face away.

I feel bad for lying at her. Focus on the mission! Kaullo smiled brightly at the woman, it was a fake smile of course. "Arigato, oneesan! Mommy's name is Lydia and daddy's name is….Ano… David!" He then placed a finger on his lips, thinking for a fake name. "My name is Lulu…."

Thanks to the little research Milluki did for him, Kaullo memorized all the inhabitants of this hotel. Kaullo silently thanked his older brother.

"Lulu? Aw, even your name is adorable. I'm Mai, nice to meet you, sweetie." Mai said.

Kaullo didn't like the fact that she called him 'sweetie'. Kikyou already called him like that (Or she would call him Ullo) and that was more than enough for him. He smiled nonetheless and said, "You too, Mai-neesan."

"Should I check which room number you're in?"

Kaullo nodded. Mai went back to stand behind the counter and typed some stuff on the computer. After a while, she smiled and said, "Found it. Your room is room number 402 on the fifth floor. I'll ask someone to bring you there, alright?"

Kaullo didn't answer and instead, stared at his target who walked by with his two bodyguards. He wondered how hard it would be to kill him…

After waiting for five(boring) minutes , his escort came and bought him to "his parents" room. Kaullo begged the man if they could use the stairs instead of the elevator, and after a long time of begging and batting his eyelashes cutely the man gave in and they walked to the stairs. Kaullo knocked the man unconscious and hide his body. "Gomenasai," He apologized. "But I have a mission that I have to do."

The emerald-eyed boy went to the fourth floor and ran to his target's room and sneaked inside. He easily found a place he could use to hide and activated his Zetsu. 'I hope it won't take too long. I can only maintain my Zetsu for fifteen minutes… Hm, I need a lot more training.' Lucky for him, his target arrived two minutes later. His two bodyguards blocked the door, standing outside.

Her target sat down and started reading a book. Kaullo silently walked over to him and grabbed his throat firmly. His target make a choking sound but Kaullo ignored it and started choking his target. "Geez." He said in a whisper when his target was still alive and struggling to get some air. "Can't you just die? That would make things a lot easier. Look, Kaullo doesn't have anything against you, Kaullo is just doing her job." The veins on his hands became visible as he made his hold stronger. The poor man died soon. Kaullo stood up and wiped his hands. "Gomenasai," He apologized to the corpse.

He made his way to the window and opened it. His father saw him and asked him in a whisper, "Did you succeed?"

"Yeah." He jumped out of the window and landed on the street below, next to Silva.

The journey back home was long, mostly because they were walking. Silva persisted that they walked home instead of using any method of transporting. Kaullo's feet were aching when he made his way back to his room when he finally arrived. He only put one foot in the room as Elilou glomped him in a hug. "Kaullo-sama, I'm so glad that you're alright," she said.

He sweat-dropped. "Yeah Kaullo is alright, it's not as if Kaullo would die."

"Even so, I was so worried about you!" There were now anime tears streaming down her face. "Don't ever bring your life in danger, I wouldn't forgive myself if something happened to you!" She buried her face in her hands and continued crying. Kaullo sighed.

(*O*O*O)

After that day, Kaullo had missions every day. He thought that it was a bit suspicious that he wasn't allowed to see his beloved oniisan, but decided to keep his mouth shut. But it became even more suspicious when he didn't interact with Killua for two year. Even though that they lived in the same place, it was hard to see each other. He didn't know if his father did it on purpose, but Silva send him on missions which would take a long time to finish and he would only come back at night. There were also a few times where he was out of the estate for almost a week. During that time, he couldn't stop thinking about his siblings.

'This is REALLY suspicous.'

(*O*O*O)

Two years later Kaullo tiptoed to Killua's room(He found, finally, the right moment to visit Killua. He tried many times, but either Illumi or Kikyou would catch him and bring him back to his room which was really annoying.) and knocked on the door. Hm, no answer. He opened the door and saw that Killua was sleeping. He laid down next to him. "Onii-san?" he asked in a whisper.

In reply, Killua whimpered and moved closer to him, laying his head on his chest. "Onii-san, you must be really hurt…." Kaullo muttered. He brushed his hand through his silver locks and sighed. He knew that this would work well, seeing as Killua did this to soothe him, Alluka and even Kalluto. Killua's expression of pain eased a bit. He slept a bit more soundly beside him, making Kaullo sigh in relief. Not until Killua slept more peaceful did Kaullo fall asleep.

(*O*O*O)

When it was morning, Kaullo was forced to go train with Illumi. "I come back as soon as possible, onii-san…" He said. He kissed Killua on the cheek and walked out of the room.

Knowing where he had to go, he walked to a metal door. As he opened the door he shuddered at the unpleasant feeling hitting him. The room was dark and he had trouble seeing.

"You're now old enough for electricity training. You will come here every Saturday and Sunday." Illumi said.

"Electrity training?" Kaullo asked." Is that what Onii-san has been up to for those two years?"

"Yes." Illumi nodded. "And now it's your turn."

"T-That's really nice, Illu-nii, but Kaullo passes!" Kaullo wanted to run out of the room, but Illumi grabbed him by his collar and carried him inside the room, ignoring his cries for help.

He set him down inside the room and gestured to things that Kaullo thought were cups and chains, which they weren't. Kaullo trembled, not able to make a single sound out of fear.

"Kaullo."

"N-No…." Kaullo gripped his short tightly and continued looking down, tears in the corner of his eyes. "K-Kaullo doesn't want to be here… L-Let me go back to Onii-san…Onegai…."

Illumi kneeled down in front of him and lifted his chin so that he would look at him. Kaullo shivered as he looked into the black, emotionless, eyes of his eldest brother. Since when was his brother so scary? "This is training. All Zoldycks went through this, you're no exception. Now it's your turn."

"Why?" Tears were streaming down his cheeks." Kaullo doesn't want to! Why does she have to do it if she doesn't want to? Can't she decide on her own?!" He shouted.

"It's to become stronger. So stop whining and do like I tell you." Was Illumi's reply.

With teary eyes, Kaullo walked to the handcuffs and put the metal cuffs on. Kaullo gulped as he felt his body hovering above the ground. And as he saw Illumi walking to the control panel he screamed bloody murder. "NOOOO! LET ME GO! LET ME GO! LET ME GO!" He started pulling at the handcuffs, desperately trying to break free.

Illumi turned the control panel on. A second later Kaullo got electrified. He didn't bother to keep himself from screaming and screamed loudly, he was sure that if the room wasn't soundproof everyone would hear him even at the other side of the mansion. The electricity continued washing over his small form as he continued trying to break free. Illumi didn't make a sound as he watched his brother's torture. At moments like this I wish that I could die… Kaullo closed his eyes and fainted a few minutes later. Illumi crossed his arms and stared at his brother pointedly.

(O*O*O)

"No! Onii-san, don't you dare to leave!" Kaullo desperately ran after his oniisan, Killua. Killua sighed and turned around to face him. Kaullo hugged Killua's arm tightly, sobbing. Killua's eyes softened and he pulled his younger sibling closer, hugging him.

"I can't take you with me, I'm sorry…. I have to do this alone. But I come back one day and then we leave together, okay?" He ran his hand along Kaullo's long wavy light brown hair. Today, the boy decided to keep his hair loose. "Who would take care of Alluka and Kalluto if you left too?"

"I can't protect Allluka and Kalluto alone…. You know that I'm not strong enough to fight against Illumi and our parents."

"You do fine." Killua kissed his forehead. "I come back. I promise." Kaullo gasped when Killua disappeared so quickly that he still felt his arms around him. He heard him close the door somewhere else.

"Oniisan…." Kaullo looked at the floor. "You left me…"

He shivered when he heard footsteps behind him, approaching him. "Kaullo, it's time to train," Illumi said. Kaullo wiped his tears away and turned around to face him and nodded.

Kikyou appeared next to Illumi and said, "Illumi, I want you to bring Killua back home. I can't allow my son to wander around without me knowing where he is. He should be here training." Illumi nodded and disappeared.

"Sweetie, come with me. Today, I'm going to train you." Kikyou said gently. Kaullo almost wanted to puke because of the sickening sweet tone her voice had. He didn't want to train anyway, he wanted to go with Killua.

When Kaullo didn't answer, Kikyou grabbed his hand and dragged him behind her to the training room. Kaullo felt like emptiness around him was swallowing him as he fought back the tears.'Oniisan… Come back quickly please….'
