You can tell if an actress is a major new star just by her debut setup. This actress not only had her debut scheduled for July during the summer blockbuster season, but the evil empire "S1" also gave her high praise, saying her looks are on par with the leading ladies of morning dramas. Who is she? She's Jun Kousui (or Jun Kōsui), the one whom "S1" didn't stop at comparing to Arina Hashimoto and calling her a "straight-ball beauty," but went further to label her as the top-tier jewel of the highest-grade diamonds, and even claimed this newcomer has the caliber to stand in the C-position of an idol group. All these titles are enough to show how elevated her status is, so is her actual performance really that impressive and not just hype? Let's break it down together. Her pink cherry-like lips, crystal-clear bright eyes, palm-sized oval face, and that innocent yet slightly melancholic hazy gaze are indeed top-notch, but the one drawback is her somewhat slender build with less impressive bust. However, Jun Kousui's skin is as fair and translucent as snow, giving her an alluring transparency, and her slim yet curvaceous waist and perky buttocks help make up for the upper body's shortcomings—overall, it's a case where the flaws don't detract from the virtues. Finally, let's talk about Jun Kousui's acting skills; I'd describe her in one phrase as "still as a maiden, swift as a hare." She switches modes based on the character's role—if she's playing a dominant aggressor, she'll act like a nymphomaniac, fiercely attacking the male actor's tool, fully immersing herself in the blowjob, and during doggy style, she'll grip the bed railing to ride him herself while seductively locking eyes with him. But if she's in a submissive role, she'll enter a state of "at the mercy of the blade," completely yielding to be toyed with, eventually begging helplessly in a pitiful manner that stirs uncontrollable desire. Jun Kousui's performance lives up to her hype, but she still has some ground to cover to reach Arina Hashimoto's level.
