Appearance: Reze appears to be a young woman or girl, and is of slender build. She has shoulder-length purple hair and emerald-green eyes. She is shown to be prone to blushing heavily. While posing as a civilian, she is seen wearing a choker in order to conceal the grenade pin in her neck, which she uses to transform.
In her debut appearance, she wore a loose shirt with stylized drawing of a bell on the front, and a backpack.
Personality: When introduced, Reze initially appears to be a kind and gentle girl who has a crush on Denji soon after meeting him, taking interest in him at first sight and was portrayed to be as somewhat enthusiastic, as shown when both Denji and her have a drink of coffee at the Café she had worked at. She is shown to be laughing at his jokes and isn't afraid to get close and intimate with him.
Reze is also shown to be a bit of a tantalizer, teasing Denji on some occasions, such as when she had seen how he forced himself to drink the coffee and teased him for being "such a kid," While also displaying a rather sympathetic side to her, showing her concern about Denji never attending school as a child or in his current position. She shows little respect towards the owner of the café she works at, calling him a cheapskate for docking her pay.
This was later revealed to be just a façade in order to get her closer to Denji; even her seemingly true reactions like blushing in his presence were results of a harsh military training that Reze was subjected to from a young age.
However, Reze had shown mercy towards Denji despite her mission, and at the end of the Bomb Girl arc, Reze missed her train to meet Denji again at the café, to take his offer on running away with him.
Despite her fake crush on Denji, Reze somewhat reciprocated his feelings towards her, and empathized with him since they had both never been to school before. Although using more manipulative type of fighting, she seems to not enjoy killing or harming others and prefers to avoid it, unless it's necessary for her mission.
Reze became human in an instant and lost her demonic powers.
