Hunter X Hunter (2011)

After arriving in the Republic of Podokea, Gon, Leorio, and Kurapika board a tour bus to Kukuroo Mountain, where Killua lives. However, they're blocked by a massive gate. Anyone who attempts to enter through the side door is eaten by the watchdog. Gon tells the guard that they are friends of Killua and asks to be let in.

Gon and his friends have decided to pass through the Trial Gate to see Killua. First, they must train in the servants' residence until they can open the gate. Meanwhile, Killua has learned that Gon and the others are here to see him. Gon, Leorio, and Kurapika are able to open the gate after completing their training, but the apprentice butler Canary stands in their way.

With help from Canary, who is concerned about Killua, Gon and his friends are getting closer to the mansion. However, Kikyo tells them that Killua cannot see them as he is in solitary confinement. Meanwhile, Killua has been summoned by Silva and asked if he wants to see his friend? Killua answers truthfully, and he is allowed to go see his friends...

Canary guides Gon and his friends to the butler office. There, they meet the butler Goto, who challenges them to a coin game so he can determine if they are worthy of being Killua's friends. After winning the game and reuniting with Killua, Gon now looks ahead to his next objective...

A letter from Gon arrives at Whale Island for Mito... (A recap of everything that has happened.)
