Assassination on the Kill

The school bell rang, a familiar symphony signaling the end of classes and the chaotic rush of students. Amidst the throng, five peculiar figures moved with an unusual calm. Katherine stretched, a groan escaping her lips. "Arhhh! Finally! I wasn't sure how long I was gonna last in Math class. It was bad enough that the day started with English lessons."
Jennifer nudged her playfully. "Says the girl who was hardly paying any attention to the verbs, tenses, and equations!" The whole group chuckled.
"What's after recess? Science?" Tricia mused, already a step ahead.
Takahiro, ever the precise one, corrected her. "No, it's Geography. Get the difference already."
Iris, always the pragmatist, glanced at her watch. "Guys, shouldn't we get a move on? We all know we can make it to class in less than two minutes, but we need time to eat, right? Especially someone." She eyed Katherine pointedly. Laughter erupted again.
"Haha, Kathy does eat slow, doesn't she?" Jennifer laughed. Tricia, already walking faster, called back, "Ehh, guys, fifteen minutes have already passed! We only got twenty minutes left. Can we pick up the pace?"
The other four exchanged grins, then broke into a run, easily overtaking Tricia. "Race you there!" they shouted in unison. "Hey! No fair!" Tricia exclaimed, half-amused, half-annoyed, as she watched her friends sprint towards the canteen, their everyday school lives seemingly indistinguishable from any other teenager's.
