Kaori's the target!! Words of love mean goodbye (Part 2) - S2.E4

Kaori seeks hiding from the Silver Fox with Umibozu. She then catches Ryo babbling to Saeko babbling about how Kaori is just crazy about him and how he does not really care about her and that Kaori is unfit to be Ryo's partner (even though Ryo really cares for Kaori). With that revelation, she seeks training in creating boobytraps from Umibozu and seeks to take matters in her own hands by challenging the Silver Fox herself.
