My favorite broship would be Killua and Gon from Hunter X Hunter. Why? Because I like the fact that Gon is Killua's light. Killua was born into a family of assassins, ever since he was a kid he had to kill and live in the darkness. Never actually enjoying his life as a kid. Or having a friend standing next to him and helping I'm out. Then Gon came along and because Killua's friend and showed him there are other ways to handle stuff than killing. Also that friends will always be there for each other and have each others back.
