クリスティーナ ホステトラー

Originally presented as Kouji's betrothed, Christina hails from the US as the daughter of a high executive for the McDowell's fast food restaurant chain. While very new to Japanese culture, she's more than willing to follow on the arrangement made by her mother and Kouji's father, and dedicates herself to being the ideal wife for Kouji.

Of course, there's more to this story. Aside from being Kouji's fiancee, Christina is also an "agent" for the McDowell's company, and is assigned to protect Kouji.
