I watched the undercover investigation-themed AV starring Rena, and it was quite stimulating. The plot features a justice-driven investigator infiltrating an evil pharmaceutical company alone, building anticipation with its tense development. Particularly impressive were the scenes where Rena kept wearing long boots throughout, maintaining that style in her performance created a unique atmosphere that fans would find irresistible. In the climax where her cover is blown and she's injected with a super-potent aphrodisiac, her body reacts intensely, depicting her drowning in unbelievable pleasure. However, some scenes felt lacking, with loose restraints and underwhelming intensity in the torment. The expressions of resistance and convulsions were weak, and the nobility and strength weren't fully conveyed. Overall, it's a work that boot enthusiasts can thoroughly enjoy, but viewers seeking more extreme developments might find it a bit unsatisfying. Still, the impact of the aphrodisiac-induced transformation and gangbang scenes is worth seeing.
