Yuuri Kenbishi is a core member of the Yukan Club at St. President High School, hailing from elite lineage as the daughter of Mansaku Kenbishi, CEO of the global Kenbishi conglomerate, and Yuriko Kenbishi. Her family’s substantial wealth and status define her background, and she has one older brother. Standing 166 cm tall with light brown short hair, Yuuri’s pretty appearance sharply contrasts her unrefined mannerisms and lack of traditional ladylike behavior. She frequently changes outfits, occasionally choosing cartoonish styles, and exhibits dramatic shifts in expression between joking and serious faces.

Possessing superhuman strength and reflexes, Yuuri employs her "iron punch" in combat but cannot surpass Seishiro Kikumasamune’s fighting prowess. Academically, she struggles profoundly and cannot study effectively. Her personality is energetic, willful, and impulsively carefree, often leading her into trouble; she displays a substantial appetite and a spunky demeanor, and owns two cats.

As sports club president and Rock Club participant, Yuuri leverages her family influence, physical talents, and club connections to solve mysteries. She drives the group’s investigations through direct confrontation and action during incidents.
