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.
