Musume Ronshaku simply smiled and laughed as she left another one of her newly-dumped "boyfriends" behind, drained of his money and utterly crushed. He had spent every last yen to take her out on expensive dates and to purchase pricey gifts for her, but now that he was penniless, he was utterly worthless in her eyes. Sure, he was devoted, but Musume wasn't looking for guys with devotion. In fact, she just lived for that moment when a man's eyes filled with heartbreak.
As her laughter died down, Musume pondered who her next victim would be. Draining men of their life savings and smashing their hearts afterwards was fun and all, but it got repetitive after a while. And besides, her father could provide her with all the luxuries that money could buy. The problem was finding out what she could do instead.
While she mulled this over, she pulled out her phone and went to her contacts list. As she scrolled through it, she glimpsed the name of her friend, Kashiko Murasaki. Musume instantly remembered what she knew about the girl; namely that she was a huge slut. The term was harsh, but accurate, as Kashiko had a reputation among their group for sleeping around. Not only that, but she was also capable of practically enslaving men to her using sex, an ability that Musume both respected and envied. She had slept with a respectable number of men herself, but not to the point where she could enslave them to her without blackmail. Besides, she enjoyed crushing them more than having them.
Musume came to a complete stop as she suddenly realized something. She started turning in place and muttering excitedly to herself, a huge grin spreading across her face. In her head, she thought of three simple English letters which formed a well-known acronym in her own language. Musume quickly speed-dialed her friend and told her about what she had planned.
"Like, ohmigod Musume!" Kashiko laughed, "That is the best idea you've ever had! Like, ever!"
"I know right?"
"So who's the unfortunate victim gonna be?"
"Oh, I've got an idea." Musume grinned evilly as she cast her thoughts towards a certain boy with black hair.
