Cefca

Cefca (real name unknown) was an antagonistic character in Mobile Suit Gundam Y.

A beautiful and mysterious young woman, she appeared to Aldrich Reno during his struggling to cope with the changes happening to his body (as a transformation into a Shell), and left him cryptic messages, showing an interest in the young man. She continually appears throughout the series, helping him some times and merely watching his actions when she doesn't. Over time, Aldrich begins to trust her, and he feels that a powerful bond is beginning to grow between them.

However, it all proves to be merely a ruse. In truth, Cefca is a manipulative and heartless person. Believing in her superiority as a result of being a Shell (and being one of the most powerful ones at that), she persuades Aldrich into actions that began to destroy his humanity and his relationships with his comrades little by little, fooling him with her fake "love".

In the end, she is destroyed by him in the Gundam.
