She is young woman, with average height and shoulder length straight dark hair. She wears a light-colored striped suit with darker shirt under it. She also has freckles around her nose.
Ruizawa is cheerful, nice and is always smiling. Although extremely nice, she doesn't feel anything if a child ghoul is killed, since she doesn't consider ghouls humans and can say that while still smiling.
When Ken and Touka went to give false information about a ghoul at CCG, Ruizawa was the one that spoke with them. After telling the false information, they asked her how the investigators fight the ghouls, since they are a lot stronger. Ruizawa said that she can't reveal that information, but said that two strong investigators have come to their branch and that the mother ghoul was killed by them, and said they will find the child ghoul soon. Touka said that must be a heart-breaking, to kill a child, but Ruizawa still with a smile, told her it's not like that, since ghouls aren't humans and since they will cause them trouble, it's natural for them to kill the ghouls. After that Touka and Ken left.
