Yozakura Quartet: Hana no Uta S00 E05 Yoza-Quar! #5

"In a town where humans and demons co-exist, it takes more than a normal police force to maintain the peace."

Kyosuke and Akina play on their DS. Touka bursts in knocking Kyosuke away, and tells them they should be studying. Akina ask why Touka there, to which she explains it is her job to discipline slackers. Robo Ao enters having detected an invader. Touka and Ao fight to the point where Touka gropes Ao’s breast discovering they are real. Ao’s mask is removed revealing she is not actually a robot. Ao fires her finger guns at Touka but Akina tackles Touka out of the way. Akina ends up groping Touka’s breast and is punched away by her. Ao draws the scenario, which Touka rejects.
