2x19 - Yu Yu Hakusho

Genkai tells Yusuke his final test is to kill her. Yusuke has second thoughts. He meets Genkai in a cave and says he can't do it. She tells him that was the first part of the test. She would not give her power to someone who would kill her. She reveals her source of power is her Spirit Wave Orb. She takes out a bright ball of energy. Yusuke's test is to absorb it. He agrees to the terms, though the test could kill him. She puts it in him. He feels nothing at first, but then he collapses and pain. In a new ring, the semifinals begin. Team Urameshi enters, missing two of their members (Genkai and Yusuke). They are facing Team Uraotogi. Hiei and Shishiwakamaru agree to choose the fight by dice. The first fight is Hiei vs Makintaro. Hiei wips out his katana. Makintaro asks him to make a move. Hiei holds up Makintaro severed arm. Makintaro reveals his attack, the Axe-blade fist. Hiei is too quick for him and stabs his head. Meanwhile, Genkai watches Yusuke suffer through her test.
