She ends up getting catched by the guards.

This particular day had been a very bad one for Mercedes so far, for not only she had forgotten about wearing panties yet again, but this time her noble parts had been seen by not one but two entire classes of students, and that was on top of the numerous other onlookers in the hallways watching her bare butt as she tried to run back to her room.

"C'mon, C'mon, it's getting close", thought Mercie for herself as she was getting closer and closer to her destination, hoping that nothing else would happen to her until she arrived there, for the last thing she wished at the moment, was for getting into even more trouble than she had already had today.

Yet, destiny is a bitch, and so, as soon as it looked like she would be arriving back to the dorms unscathed and unseen, an strong set of arms suddenly pulled her by her shirt away from her path, forcing her to stop her bottomless run.

"Gotcha!", exclamed the lucky guard of the academy as he managed to pull mercedes towards him to aprehend her.

"NO!!", Mercedes shouted as she quickly tried to escape his grasp, only to stop once she saw that she was getting surrounded by more guards.

"Wow, after all those crazy streakers last month, looks like we finally managed to catch one!", joked one of the guards to his coworkers, as they erupted in laugh at the sight of the bottomless girl in front of them.

"W-What are you going to do with m-me ?", asked Mercedes fearful as she used her free hand to cover her exposed bottom with her shirt the best she could.

"Don't worry, we are just going to take you to the facultry so that they will dictate you the appropiate punishment", a serious guard explained to her. "Now, mind you, if you try to escape or resist further more, that will definitedly add to your sentence, so it's better for everyone here if you cooperate with us", the guard warned.

Faced with the prospect of being dragged bare bottomless to the facultry office, Mercedes knew that she was in a very tough stop right now, in which she didn't know what to do, for in one hand, she wanted to escape from the guards to get something to cover herself at least, but another part of her knew that she was already deep into trouble already, and that if she resisted, she might get suspended or even expelled from the school completedly.
