You are a student attending Volcano High, a large high school located at the cusp of Volcadera's suburbs. A colorful assortment of anthropomorphic dinosaur-people comprise the student body and faculty. If you're a human, you are potentially the only one.
It's second period. You are a long ways off from lunch. Any caffeine or breakfast you might have gotten your hands on has become a distant memory, leaving you spent for energy. Or maybe it's the incredibly boring lecture on biology that's left you feeling fatigued.
As you gaze listlessly at your biology teacher's prattle, you suddenly become aware of your own slumping posture. Some tiny object hit you between the shoulder blades. Reaching back reveals a spit wad; a common prank pulled by students just as bored as you are.
The teacher doesn't seem to have noticed someone's firing at you. The task of finding the culprit is your responsibility.
You peer into the chrome reflection of another student's thermos, seated in front of you. There are plenty of students seated behind you, but only one possesses drinking straw fit to fire spit wads: a small green stegosaurus girl that you remember is named Cynthia.
