Being the president of the Student Council and a daughter to her influential parents, whom are both responsible in enforcing the ever stricter public morality laws, Anna is a soft-spoken and innocent yet strong and determined girl whose role is to get rid any materials that are deemed obscene or lewd not just in the school, but also in the society as a whole.

Behind her seemingly regal personality however hides a much more bizarre one which is hidden away from the public. That personality is one-sidedly known only by a few people around her, especially Tanukichi who accidentally kissed her while saving her from stalkers, which ironically somewhat arouses her. In this persona, Anna is much more determined—if not sadistic—to enforce the laws for the sake of "love" while attempting to capture Tanukichi's affection. For these reasons, Anna also possesses yandere persona in order to keep other women away from Takunichi.
