Here’s a fascinating rookie.
IQ 140, dubbed “Science Onee-san”, Suzune Rui grew up in a family of physicists, mathematicians, and chemists. From childhood, she was drilled to prioritize academics—a perfectionist who lived by logic. Yet before she knew it, she turned 23…












Studying remained top priority, but one question haunted her: At 18, she lost her virginity and discovered something science couldn’t explain. Why does sex feel good? Why does each encounter feel unique? And if orgasms are quantifiable—has she peaked? The paradoxes consumed her. Finally, she made a decision—
To enter AV. She’d recruit “young guns” for academic research, craving deeper carnal knowledge.
Admittedly, Suzune Rui feels atypical for Kawaii*. Short-haired and sweet-faced, she dons lab coats for her “scientist” persona. Her curves surprise—though some might find her too familiar. Compare her to FC2-PPV-4574068’s star: same bob cut, same ample bust, same delicate features…
A quick FC2 search confirms: uncensored, creampie scenes. The moles on her back and inner thighs match. And she didn’t stop at one—FC2-PPV-4605794 is also her. Want full disclosure? Easy.











Now, the elephant in the room: Why yet another Kawaii newcomer with an uncensored past?*
Lately, Kawaii* keeps debuting actresses with FC2 histories. June alone brings two (more on the other later). Is this due to lax vetting—or are their partner agencies prone to “leaks”? My theory: Kawaii*’s short-term contracts attract mercenary types, often from the fuzoku (adult service) world. These women favor quick cash-ins, explaining the FC2 crossover.

Silver lining? It’s excellent training for fans’ “Sharingan eyes” to spot these veterans!
