"I never felt like this before coming here, but... do there have to be so many humans? They're freaking everywhere". 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". As the "Fallen Angel", Gab is the opposite of what she was - sarcastic, uncaring and lazy. As time goes, her personality sunk even more to the point where she is not shy to use deception in order to keep everything goes to her interest, such as lying and acting to her sister Zelel that she is still the "Prodigy Angel" she was and finally she remained as "Fallen Angel" until the end.i Gab is also quite selfish, when her team are having cooking class she buys the ingredients for something she wants to eat instead of the one she needs and later, she adamantly refuses to wear a costume that Vigne has made for her. *Another Gab's positive side is she remained intelligent and crafty despite being lazy, which is why she never fails her exam as well as why Satania can never outsmart her. She is also quite informative and observant, as she found out that Master is the owner of Satania's apartment and correctly pretends to speak in broken Japanese to convince Master that she is a foreign student.Despite being a "Fallen Angel", Gab is genuinely kind-hearted, friendly and loyal to her friends. As she (at least) does not lie to Zelel when saying that she wants to stay on the human world because of the friends she made in there. Also, Gab will never abandon any friends in need, she even helped Satania adopt the dog by pulling some strings. Whenever the gang hang around, Gab never complains to be in their company, showing great sense of friendliness despite her selfishness.
