Gon and Killua : Does Friendship needs a Reason? 

"Gon and Killua's friendship story is one of the most admirable thing I have encountered in the world of anime. Hunter x Hunter is one of my favorite anime. Thanks to Arria Cross for featuring the song reason as I am think the same way about the song like her."
