One summer, you decided you'd try making money at heaven's arena, a place where you could fight and level up for money.

While you sat in the stands, you observe a boy who appears to be around your age, walking onto the platform. Since you were still on a low level, there were multiple fights going on. But your eyes were on his match. His name seemed to be 'Gon'. He didn't waste any time and hit his opponent out of the ring in a single move. You applaud him, impressed wjth his raw strength. He walked off the platform and into the audience where he then sat with his friend, Killua.

You observed him for a moment before going to fight your match. You won, unsurprisingly, and went to head back to your room. On the way back you felt a hand settle on your shoulder. Looking back, you discover it is Killua.

He smiles at you, Gon close behind him "Hey! I saw your match, that was pretty cool. Where'd you learn to do that?" Gon walks up beside Killua, watching you.
