Go to the principal for help

The principal! He'll be able to fix this! Hopefully. You've never actually met him, but he was put in charge of the most prestigious hero school in the country, so he's gotta help.

As you make your way into the cafeteria, the first bell rings and everyone gets out of their seats to head back to class. You don't see Jiro or the others anywhere before the room is full of moving bodies. You try to keep an eye out for them, but as you move throughout the massive room, your keep getting distracted. Mere glances of... something. You can't tell what is drawing your attention until you're stopped by Uraraka. "Hey Chiba! I thought you were going to be late after you went with Jiro. Did everything go alright?"

You don't listen to her words, your eyes are immediately drawn down to her body. You stare directly at her chest as you feel yourself heat up. That's what it was, almost anyone nearby was distracting you, each passing body would catch your attention for a mere moment. Your mind fills with lewd thoughts of Uraraka without her clothes on, you without your clothes on... Both of you fucking as you make her your own personal- "Well... I don't want to be late." She snaps you out of your downward spiral of sinful thinking. You blink as she turns around to head to class.

"That ass is fucking perfect..." You think. You can't just sit here like this, you need to do something about it. Quickly you run up to Uraraka, you grab her shoulder and wait for her to turn around.

"Woah! You okay Chiba?" She says with confusion.

"I will be~" You practically moan as you reach down and squeeze her plush ass. Uraraka gives a little yip in surprise but is silenced when you lean in and lock lips with her. "This is what I needed~" You think to yourself. The only thing that would make this better is actually fucking-

"What am I doing?" You quickly **** yourself off of her as lust burns through your body. You don't know what to do, you need to get off, but you can't do it here!

Uraraka takes a step back. "Woah! I'm sorry Chiba, I- I'm not... into girls." She says with a shaky smile before turning and quickly rushing away from you.

"I'm not either... I just..." You think. Though the further you think about it the more you realize how untrue that statement might be now.

By now the cafeteria is empty, leaving only yourself. You pant as the burning lust in your body eats at you, you want to just pounce whoever you find yourself by to satisfy it, but you can't! You unbutton the top buttons on your uniform to help you breathe and continue on. You need to get to the principal, even if it kills you.

It's only when you're in the hallway passing your classroom that you realize you're showing off your new cleavage. You had just unbuttoned your shirt to cool down but even though it's helped, you just can't bring yourself to button it back up.

You make it all the way to the principal's office and take a deep breath. You hope to God he believes you...

You reach out and knock on the door in front of you. A few moments go by before a quiet voice is heard from inside calling you in.

Once you have the green light, you open the door and enter. The room looks fairly standard from what you can tell, you don't know why but you kinda expected more? "Can I help you?" Your observations are cut short by the principal. You look straight ahead and see... Something sitting at a desk in front of you.

"Uhhh..." You're not sure what to make of him. If you didn't know any better you'd say he has some sort of animal quirk, but you know about his IQ quirk so you're not sure what to make of- "Yes, I get this reaction a lot. I can explain it to you later if you'd like. But right now I am incredibly busy, was there something you wanted to talk to me about? You are one of my students right?"

You snap out it and decide to just get to the point. "Sir, I think there's something terribly wrong going on in the school! I came to you for your help to stop it!"

"Something wrong? Wrong how?"

You spend the next few minutes explaining your experiences of the last few days to catch the principal up. He seems to listen intently, as if your seemingly far fetched tale has caught his attention.

"Yes... I have heard about the attacks, and how one of our students were involved. Though I didn't imagine anything more would come from them. You say those beasts were 'corrupting' people?"

"Yes, along with anyone who has already been corrupted. It's like a disease, several of my classmates and one of the teachers have been affected already."

Principal Nezu closes his eyes to think for a moment. "And you haven't been affected? You said you fought with them."

"No! Of course not!" You blurt out suddenly. You're not sure why you do, but you suddenly have a strong desire to hide how you've been affected, as if coming clean to him would turn out bad for you.

"Alright, the school should be mostly empty by now, I'll pass this information around and keep an eye out. Head home for now and let me know tomorrow if you remember anything else that may be important."

"Thank you sir." You say with a small bow before turning and heading out. "Fuck, now you're telling me I've gotta wait until tomorrow? Half the school could be turned by then! What the hell am I supposed to do?"
