S2·E3 Kaori's the target!! Words of love mean goodbye (Part 1)

Humiliated in their last encounter, the Silver Fox pledges revenge against Ryo. He issues a formal challenge to Ryo by saying that he has targeted Kaori, Ryo's "lover" for death and that Ryo must protect her from his attacks. When Kaori confronts Ryo about this, Ryo acts non-commital to the challenge. After an incident in which Ryo falls for a trick set up by the Silver fox, he informs Kaori that she is no longer to be his assistant.
