自律思考固定砲台 律
(Jiritsu Shikou Kotei Houdai, "Autonomous Thinking Fixed Artillery"), nicknamed 律 "Ritsu"

A robotic "classmate" that joins the cast of [[Ansatsu Kyoushitsu]] (Assassination Classroom) in chapter 20.  Her virtual form is that of a middle school girl, while her physical form is reminiscent of the black monolith from [[2001_a_space_odyssey|2001: A Space Odyssey]] with a video screen or the appearance of a rather large [[digital media player]].
