Rock x Scissor x Heart
Gu × Choki × Hato
Part of Leorio's test is to guess the gender of his fetching opponent, Leiluto. He deliberately fails, in order to win a grope (much to the exasperation of the rest of his team). Killua's test is a fight to the death against "body-ripper" Johnny (or Jones the Cutter, depending on the translation). While the others are pleading with him not to fight, Killua professionally rips out Johnny's heart.
