With the revival of authentic succubus VR, what caught my eye during my slump as an erotic manga artist was the overwhelmingly sexy-bodied succubus played by Kamiki Rei. The slightly larger size typical of SOD, along with the preferred image quality and sense of distance, is exquisite, offering a highly immersive work that easily draws you into its world. Just being able to see her beautiful face and natural body up close is highly satisfying. Particularly, Kamiki Rei's ecstatic expression is in a league of its own compared to previous exaggerated faces, allowing for enjoyment without any sense of discomfort. Among succubus works, its exceptional eroticism has a charm that makes you want to watch it over and over again. While some voices wish for less focus on setting and more on a natural private SEX-like atmosphere, this work transcends even that. Missing Kamiki Rei's ecstatic expression would be a lifelong regret.
