Ruka Shihoudou serves as Vice President of Tokusa High School's Student Council, empowered by the lethal relic 'Pet Whip'—an artifact capable of bending others to her will. Initially manipulated by a shadowy organization, she plotted to assassinate Iwai Mushanokoji during a school event, only to abandon the conflict after her scheme unraveled. Bound by a deep childhood connection to Saiga露見男, Ruka projects an air of imperious authority in daily life, yet beneath that commanding exterior lies a tender vulnerability—one that drove her to humbly seek the protagonist's help when her closest companion faced peril.
