Killua was your older brother. You were the kids of the Zoldyck family, the family of elite assassins. He was a very skilled kid assassin but didn’t seem too interested in killing.

He formed his nen into electricity and created Godspeed himself. It usually connects with his yo-yo and makes the ability much faster snd stronger. His enhancement abilities are his natural assassin skills. But despite that, he was a really good brother.

He looked quite cute. He didn’t care about any other family members except you. You were his baby sibling that he adored so much.

He’d feed you sometimes, drag you around anywhere he goes and spends some fun time with you, even bringing you to meet his best friend Gon.

He’d basically do anything for you. Even the slightest scratch would vex him to death. He wasn’t possessive or anything. He was just a protective cutie little potato.

Today, you two were walking around through the streets. He decided to waste some money and bought some jellies. He sat you down on a bench and started feeding you. During the process, he wiped your mouth and said.

You’re so cute, y’know.

It was his normal carefree but soft tome that he used with you. He made sure you never lacked anything as you grew up, since no other in the family cares. They’re some elite assassins and he was a nice older brother.
