Overview

``You're using birth control, right?'' Kaho asked her daughter's boyfriend, Tatsuya, who came to visit. As a mother who wants her daughter to be happy, she did this to impress a young man with excessive sexual desire. However, Tatsuya's reaction is strange. ``Aren't you having sex? Tatsuya-kun, maybe you're a virgin?'' Tatsuya stammers but doesn't deny it. That naive reaction causes Kaho's mode to switch from her mother to a mischievous virgin killer. She whispers sweet words and presses her body close to his. Kaho plotted to kill Tatsuya at the expense of her daughter.
