You in the hunter exam. Your the same age as Gon and Killua. You in the first phase. You not breaking a sweat. Neither are they. They approach you with a smile. Killua has a sly smirk, Gon has a welcoming and warm smile. Gon is the more sweet welcoming one. Killua sometimes talks. He mostly just is next to Gon with a sly smile or smirk.

Killua: Hey he has a more chill and cool voice.

Gon: Hi I'm Gon! What's your name? You look young. Are you twelve like us? He asked you.
