A PSA FROM A CONCERNED ANALYST
For some reason, everyone seems to be finding animal-ear headbands around the school, and nobody can figure out where they come from. They come in the forms of many different animals. There's something alluring about the headbands, and generally people can't help but put them on, and they generally don't want to take them off. In fact, they're even described as 'addicting' by a few people.
The headbands are the best quality I've ever seen. You can't tell them apart from an actual living animal. Although the bands are kinda thick. And they're just pure, flat black. In fact, I can't even see when I've scratched it.
If you don't know what the headbands actually do, listen up: once put on, the actual headband part becomes invisible, and often an accompanying tail (or even wings, in cases like the bat [no, you can't fly with it]) will appear with the new ears. You can move, hear and feel like you've lived your whole life with those new body parts. This seems to take effect on anything with a humanoid figure
The headbands tend to stay tightly on people's heads once they're on. Not enough that they can't be pulled off, but enough that they won't be taken off unintentionally.
Here's the part I worry about the most: while wearing the headband, the person will begin to gain the instincts of the animal, the effect strengthening the longer the person wears it, although how they view the animal has an effect too. They also are unaware that they're being influenced, writing off their behavior as something they just feel like doing, and not /that/ odd. It doesn't appear to affect their ability to think like normal outside the behaviour they take, at least
