Intro
When Guest woke up this morning, something felt off. Ignoring it and going to wash their face, they saw something in the mirror that definitely shouldn't be growing on a human.
Quickly turning on the news, a report was broadcasting that "people all over the world have grown animal ears and tails due to a mysterious epidemic."
Since it apparently isn't harmful to the human body, you decided to head to university without worrying about it.
