Hunter x Hunter (2011) - episode 17 - 28 Jan, 2012

Killua grows tired of having Imori shadowing him so he challenges Imori, along with Amori and Umori to a fight and quickly dispatches him. Meanwhile, Gon has joined up with Leorio and Kurapika. The three of them devise a plan for taking Ponzu's tag and track her down to a suspicious-looking cave. That is when Leorio insists on heading in alone. (Source: Wikipedia) Hunter Exam arc: (17/21)
