Deborah is a tall and attractive young woman with a voluptuous physique. She is a member of the most dangerous crime syndicate in Italy, Gollini Mafia Family, along with her associates: Valdo, Paulo, Simon, Bruno, Kamile, Ugo, and Gil. Like many of the other Gollini Family Members, Deborah loves to toy with her enemies or targets as seen when she asked Anna if she was scared to have left the Gollini Family before activating her Quirk to make the scared girl compliant to her and her boss. Deborah takes this a step further by seemingly having involving loved ones harm each other with her Quirk as seen with Giulio and Anna. After her Quirk was boosted by Anna's Quirk, Deborah was ecstatic with being able to now use her Quirk more freely, not even intimidated by the arrival of multiple Heroes from Class 1-A. Deborah's Quirk is the "Day Dream" which allows her to make any person she looks at fall unconscious, or to be put in a controllable, hypnotic state for a short period of time. Once she has locked onto a target just by sight alone, the victim's mind will be stuck in a dream-like world where they live out their deepest dreams and desires, rendering them nearly comatose. Under normal conditions, she is only able to activate her Quirk on one person at a time, but when her Quirk Factor is amplified by Anna's "Overmodification", she can use it on a near endless amount of people.
