Episode 4: The Saying Goes... Love Is Justice

After spending time in the hospital following the events at the park, Ayame tells him that she has persuaded Otome to join SOX in hopes of making more risque artwork, even finding ways to draw that the PMs can't detect, but Otome still requires Anna as an inspiration. Tanukichi soon returns to school, but Ayame is strangely absent and Anna keeps avoiding him. Later, Ayame talks about her latest plan to reclaim a hidden stash of old pornographic material located on private property. She can't do it alone, so instead she plans to lure the students from school out to the property during the weekend. However, her plans are sidelined when Tanukichi is targeted by a stalker and Anna's mother, Sophia, shows up to the school in person to get the students to support her new legislation that would force all students to wear chastity belt-like devices. Running low on options, Ayame decides to have Tanukichi confront his stalker while Otome hides in a closet to draw lewd pictures herself. However, the stalker turns out to be Anna who restrains and assaults Tanukichi while being unable to understand her feelings. After Ayame accidentally interrupts them, Anna flees as Otome begins furiously drawing the scene with her teeth. Later that night, Hyouka confronts Anna in the lobby of her apartment, asking why her science lab was sterilized without asking. Anna responds that it was done out of love, as the more "impure" influences she eliminates, the more she will be rewarded with love, therefore everything she does for love is just.
