Koroshi Ai Episode 10

Two assassins face off. The cool bounty hunter Chateau and the mysterious and powerful Ryang-ha. Chateau and Ryang-ha become enemies after this fight—at least, they should have, but for some reason Ryang-ha takes a liking to Chateau and begins following her around.

Little by little, Chateau develops a cooperative partnership with Ryang-ha, which gets her caught up in the struggle against the organizations hunting him down. Furthermore, that battle is related to her past as well. Two mismatched assassins weave together a twisted "Assassin X Assassin" thriller. The strange gears of fate begin to move.
