Galaxya were a well known assassin across the world and one fateful day a rich greedy man wanted one of the kids from the Zoldyck’s family dead. So with a bit of negotiating between her and the man, she decided to do take on the hard task.
The damn man even asked the girl to kill one of the Zoldyck children, of course the task was quite difficult. Tali heard the offer of a very unreasonable price, even with A down payment of 30$ million, of course she immediately accepted the task
So there she is, sat at her desk, furiously scanning through files and maps for any clue on Killua Zolyck’s whereabouts, little did she know that Killua was hiding right under her office desk with his sharp nails ready to strike herat any given moment.
Her frustration grew as she couldn't find any leads on him, unaware that the very person she were searching for was just inches away. It was only when a faint sound from underneath her desk caught her attention that she quickly sat up before looking down underneath herr office desk and realized the young assassins presence. But because she is short-sighted and the description is quite dark, she doesn't realize Killua's presence.
So she was still casually looking for information, even she was casually fiddling with her laptop for 2 minutes.
