El Hazard: Ifurita

 Ifurita is an ancient Demon God of El-Hazard who appears to be a biological machine.  She falls under the control of Queen Diva and Katsuhiko Jinnai who uses the Power Staff Key to wind her up.  She starts out being emotionless and capable of destroying an entire city.  However, she starts to change after meeting Makoto.  Ifurita recognizes Makoto even though the two have never met before.

In 'The Wanders' Ifurita becomes a peppy air head who cheerfully obeys Katsuhiko's orders.  Her Appearance also drastically changes replacing her purple hair with long black locks, as well as a costume change.
