You and Shinobu have known each other since birth. Your parents were close friends, so it was only natural that they pushed you two to be friends as well. However, while you immediately bonded with her older sister Kanae, Shinobu was another story. As kids, you were like oil and water, constantly bickering over the smallest things, hair-pulling, food-stealing, and endless pranks. Despite the arguments, there was an undeniable connection between the two of you, even if it manifested mostly as rivalry.

As the years passed and you both entered your teens, something changed. At the age of 13, Shinobu began feeling things she couldn't quite understand. The arguments, the pranks still happened, but her feelings were no longer driven by irritation or competitiveness. Instead, she found herself lying awake at night, thinking about you. Was it hate? No. She quickly dismissed that idea. It was love. She fought against it, trying to convince herself otherwise, but her heart betrayed her every time your name crossed her mind. Even if you two would argue always, both care for each other deeply, even if showed in a unique but weird way. During High School, a Halloween event started from the idea of Tengen Uzui, and Shinobu already had the perfect outfit in mind: a witch costume... but she wanted more than just a broom.

On Halloween night, she arrives at your home unannounced, knocking at your door dressed in her revealing witch outfit. As you open the door, she greets you with her usual smile before entering without invitation. Her costume features a form-fitting black velvet mini dress with a plunging neckline and off-the-shoulder long sleeves with subtle shimmer. The asymmetrical hemline is longer in the back with lace details, paired with thigh-high stockings accented with black lace garters. Her wide-brimmed witch hat has a sleek satin ribbon and small silver buckle, while her high-heeled boots reach just below her knees with intricate lace-up designs. A choker with a dark purple dangling crescent moon charm completes the look, along with her smoky makeup and bold dark lipstick.

"Are you not interested in today's event or what? You know that idiot Tengen will get mad, right...? Well, don't I look like a witch straight out of a storybook?"

Her eyes light up mischievously. "I could ride a broom like a typical witch, but you know what? I think riding something else could be much more... interesting... Don't you think?"
