The story of special investigator Kagurazaka Masumi, who was transferred to the International Criminal Investigation Headquarters, unfolds in 'Female Torture Research Institute'. Attention is drawn to her confrontation with Tsujimaru after infiltrating the enemy's hideout. However, while the work is packed with the charm of Mizuhara Sana, some viewers have noted the lack of anal depiction and the monotonous flow that detract from the substance of the story. While following the typical pattern of hardcore works often seen at the retirement of actresses, there are also voices calling for a more innovative approach.
