Originally, Gabriel was a prodigy angel from Heaven and number one of the Angel School, known to be very "angelic". She has a perfect and good personality, being kind, friendly, diligent and polite. This personality extended to the short time when she came to the human world until she finally found out about the MMORPG game on her laptop, her personality changed to the "Fallen Angel".

Currently as the "Fallen Angel", Gab is the opposite of what she was - sarcastic, uncaring and lazy.
