Chapter 1: BOOK

A while back, even before the Hunter's exam began… Before he ran away from home… Before meeting Gon… and before she was locked away, Killua was just spending his day like he always does back at the Zoldyck Mansion in Kukuroo Mountain.

"Onii-chan, let's play!" The younger Zoldyck exclaimed as she walked near Killua and sat next to him, but all that she heard was his snicker caused by the book he was reading. She got bothered after her brother didn't reply and called out to him once more, this time a little louder. "Onii-chan!"

This time, Killua heard her call and looked at her with a smile. "Ah, Alluka, sorry 'bout that. What were you saying?" Alluka pouted but smiled afterwards for getting his attention, "Onii-chan, what're you reading?" she asked, which startled the silver-haired boy whose face started to blush a deep shade of red.

"I-It's nothing, nothing at all!" He nervously laughed as he tried to hide the suspicious-looking book behind his back, making Alluka more curious about it. "Onii-chan~ Tell me what it is!" She demanded. "N-No way, not telling!" He answered and stood up from the couch to make sure Alluka doesn't get the said book.

Alluka ran to him and tried to get the book but failed to do so, since Killua held the book high up above his head. "Ah, look Onii-chan! Chocorobokun!" She exclaimed which certainly got the boy's attention. "Chocorobokun? Where, where?" He happily asked as he looked at the direction Alluka had pointed and let his guard down. "Gotcha!" Alluka cheerfully said as she held possession of the book Killua had tried to hide from her. Of course, knowing Killua best of all, Alluka knew how addicted her brother is to the said snack and used it to divert his attention to get the book.

"Heeeh? Alluka, that's not fair!" Killua complained but Alluka just giggled and began to scan the cover of the book. "Onii-chan, this book… it says R-18 in it!" Alluka exclaimed in surprise. "I-I'm sorry!" Killua blurted out since he couldn't lie his way out anymore for his sister has all the evidence that she needs.

"Fufu~ so Onii-chan likes this kind of stuff, huh?" "I-It's just…" The silver-haired was now scratching the back of his head with his face as red as ever. Alluka was the last person I wanted to know about this! Now what will she think of me? He thought to himself with a bothered expression on his face. "Ne, does that make you a pervert?" The curious little Zoldyck asked him. "Heeeeh?" So now she thinks I'm a pervert? "Onii-chan is a pervert!" Alluka teased him. "A-Am not!"

Alluka stayed silent for a while and giggled, making Killua confused as ever. "But I'm glad! I got to know more about you, onii-chan!" She said in the cutest tone her voice ever produced, at least that's what it sounds like to Killua. She then came near her brother and give her a big bear hug. "Alluka…" He called her name as he caressed her head and returned the hug to her. "Uhm, can I have the book back now, please?" He added. "No way!" Alluka giggled as she ran to the door and looked at him with a sheepish smile. "You have to catch me first!" She added and continued to run along the mansion's hallway. "Alluka, come back hereeee!" Killua shouted, not believing what his sister just did. But he smiled afterwards and ran after her. "I'm coming~!"

While spending this day with you, i thought we would always be together... Or so I thought... Fate can really be twisted at times, can't it?
