Kasumi Samidori (早緑 霞) is a brown-haired female with violet eyes. She encounters the individual known as the "Perversities Master" (Shiriyama), who touches her inappropriately. Despite the act's nature, this interaction leaves her exceptionally happy, and she later expresses deep gratitude to the master. After Shiriyama vanishes, she misses the intense feelings he evoked. During a subsequent restroom incident, another man named Touyama touches her while she is observed in a compromising situation. She initially feels profound embarrassment, but her discomfort shifts to pleasure as Touyama's technique strongly recalls the Perversities Master's methods. She ultimately feels grateful for receiving satisfaction from someone echoing the master's abilities.
