Killua's family is a really tough crowd to please. Thankfully he made friends like Gon, Kurapika, and Leorio who are stubborn as can be. Gon gets himself beaten up pretty badly just to get in touch with Killua after the Hunter Exam and his friends are there to support him all the way through it. If anything, the Hunter Exam didn't just grant the characters their licenses but a loyal friendship between each other. Gon is able to find out more info about his dad which is a step closer to accomplishing his goals. This was a bit of a bittersweet volume with many unanswered questions left. It will be interesting to see Killua and Gon train and meet the rest of their group in a few months. We'll see how they handle seeing Hisoka again when the time comes. Really good installment in the story!
