Kagome Ikaruga, the youngest of the Ikaruga family at ten years old, is an elementary school student. She possesses dark blue hair featuring a distinctive hair antenna and hair ribbon, blue eyes, and stands 138 cm tall. Her typical attire consists of practical dresses paired with tights.

Personality-wise, Kagome exhibits notable shyness and introversion, often appearing reserved around others, including her sisters. This reserved nature extends to a reluctance to change clothes in front of anyone. She struggles with coordination in physical activities, particularly sports and martial arts, a stark contrast to her family's proficiency. Despite this, she maintains a kind-hearted and considerate nature, demonstrated by her choice to bind her developing chest to avoid causing discomfort to her older sister Ayame, who is self-conscious about her smaller breast size.

Kagome demonstrates significant skill in household management, regularly handling cooking and cleaning duties for her family. Her culinary abilities are exceptional for her age, though not yet equal to her eldest sister Ibuki's. While generally uncoordinated in martial arts, she displays unexpected athletic talent by excelling in swimming.

Her development includes overcoming physical challenges, such as successfully performing a backflip during her school's Parents Visitation Day after dedicated practice. This achievement brought pride to her sisters and Yoichi Karasuma, who witnessed it. Socially, Kagome maintains a close friendship with Masashi, another student at the Ikaruga Dojo, indicating her capacity to form bonds outside her immediate family.

Within family dynamics, Kagome occupies a position where her older sisters Chihaya and Ayame occasionally assign her menial tasks; these interactions remain framed within typical sibling relationships. She consistently contributes to the household's well-being through her diligent domestic responsibilities.
