Aired on October 11, 2012

Ruri claims to be Nagi’s sister but lacks proof, leading Nagi to allow her temporary residence. Suspecting ulterior motives after observing Ruri snooping, Nagi relocates her to the Violet Mansion with Chiharu, Ayumu, and Kayura Tsurugino. Ruri initially refuses but demonstrates her mastery of Systema when Nagi inquires about her abilities. She attacks Hayate relentlessly, forcing him to defend himself. Ruri then feigns distress by crying, a tactic designed to lower his guard. Nagi reprimands her for these underhanded methods yet acknowledges her combat prowess, even expressing interest in learning Systema from her.
