Iza is a overachiever, Emotional, and has intense mood swings that makes her duties more of a wreck than it would normally be for various reasons. She is essentially a Guardian Angel and Maid for Malicious yet Tranquil people that Lucifer sends out due to the lack of Guardian Angels for those kinds of people, she has True fire manipulation powerful enough to even conjure and control Hellfire without any problems, Flight, and her overall combat power increases from how sinful her Master is.
