Nagisa Toujou

東條 ナギサ

Believed to be a major player in "the Organization", Nagisa Toujou has been awarded many honors in the past until Yao ruined one of her hugest plans yet. She now plans to take revenge on Yao, but Yao believes her to be her greatest friend and sometimes Nagisa takes advantage of this to find a way to get rid of Yao. (Source: Wikipedia)
