"Unhand me, little cretins! Let me go!" the female demon snarls. The magical bindings shackling her wrists and ankles may be sapping her power, but she's still plenty strong. Fortunately, you've lots of backup; for every boy she throws off, two more rush in to pin her down.
"Dog pile, dog pile!" they scream in unison, as grapple her to the floor of the coach bus.
"Gag her! Don't let her cast another spell!" you yell to your classmates. A boy rips a sock off his foot, balls it up, and promptly stuffs it into the demoness' mouth.
"Don't you dare, you little—Mmmmnnnfff!"
The she-devil is helpless to resist as her mouth is gagged by the filthy fabric.
"Yeowch! She almost bit me!" the boy cries, pulling his hand back.
You demand the boy's other sock, which you use to complete the gag by tying it over the demoness' mouth. Bound by your enchanted ropes, and fully unable to speak, she can only flail, pathetically, against the aisle carpet. The entire class of boys crowds over her, clambering over the bus seats to get a better look at the strange, female monster.
"Her skin's all red."
"Look at her horns, and that tail!"
"And wings, too!"
"Her b-boobs are huge! Like basketballs!"
"What is she, ${character.name}?" asks a particularly timid boy, peering over your shoulder.
"A demon," you answer. "They hide among humans, preying on them in various ways—flesh, blood, even hopes and dreams."
The creature snarls through her gag as her hateful, fiery gaze fixes on your own. You scoff, and plant a firm foot on her gut. Grinning smugly, you dig your heel into her navel flesh, causing her to hiss in discomfort through the sock in her mouth.
"Pretty weak, for someone bold enough to kidnap a bus full of schoolboys," you muse, mocking the creature with your smile. "Posing as the driver was pretty clever, but I'll bet you didn't anticipate a demon hunter being among the students, did ya?"
