Nina

Nina is the current generation's #9. She is cold and harsh, skilled in tactics, but a poor strategist. She is the captain of a team, including Clarice, assigned to kill an awakened one. However, they are ambushed and overpowered by three awakened ones. They were rescued by the surviving Claymores from seven years ago. Nina calls her attack "Shadow Chaser," as it tracks opponents' yoki with her blade and attacks the opponent, not stopping until its completely destroyed its target. (Source: Wikipedia)
