This work unfolds a shocking story full of the charm of the agent 'Riho'. Equipped with intelligence, physical strength, mental fortitude, and beauty, she embarks on a mission involving a new type of biological weapon, captivating the viewer in the process. What draws me in particularly in this series is the portrayal of Riho's downfall. Despite her resistance against pleasure, watching her gradually succumb is utterly erotic. Her expressions tinged with regret, along with a beauty characteristic of a gal, create an even more enchanting atmosphere. Especially, her figure is amazing, with a well-defined waist and an intense glare that is just perfect. I found myself irresistibly captivated. However, the ongoing trend of her losing to enemies, while interesting, could have benefited from a bit more realism in the scenes where she gets shot. Overall, this work is definitely worth a look.
