Igusa is another member of the pack that serves Kaoru. She has green hair, which she wears in two braids and she wears spectacles. Igusa secretly writes shōnen manga under the pseudonym 'Ruriko Saffron' and is extremely shy, causing her to be nervous when around Keita when he's in a perverted mood or when she perceives him to be thus. Despite her fear of perversion in men, she appears to be a closet fan of shōnen-ai situations herself - a fact she apparently hides from her fellow pack members.
