Hunter x Hunter (2011) - episode 11 - 10 Dec, 2011

Leorio is still betting with Leroute, a woman who plays mind tricks. He ends up losing after playing rock-paper-scissors and uses up all the team's hours. Killua goes next, facing off against an infamous serial killer who has murdered countless people with his bare hands. Killua earns a swift victory by instantly tearing his opponent's heart out, terrifying everyone but Gon, who already knew of his assassin history. With that the team has 3 victories and moves on to the next challenge. (Source: Wikipedia) Hunter Exam arc: (11/21)
