Head unimpeded to the principal's office

As you approached the door, you noticed that the door was ajar and you could hear voices talking. You peered inside. You saw Nebula and the same woman who Chris and Zoe feared leaning on the desk. The woman was completely nude, and the way she leaned over the table gave you a clear view of her large, sagging breasts, which managed to rest on the table top despite her height.

Before you could touch the door, you heard Ms. Pershing say five decisive words:

"Delores Halfwright, you are expelled."

"What?! You can't expel me! I totally called you out! You're the head of the Society!"

"...I have NO idea what you are talking about, LIKE ALWAYS!" Ms. Pershing suddenly roared, "I told you to come in and apologize to your classmates, and now here you are, fully nude, accusing me of being the leader of the mole people or something!"

"The Harem Soc-"

"AND, now I'm hearing that a literal flash-mob has invaded the senior campus and is grabbing my students! I am calling the police on all of you perverts! I hope you like being naked now, because you're going to be spending a long time wearing orange jumpsuits!"

"Good luck with that." Devoratora said with a mild chuckle.

"Hey! You can't just expel me! If you expel me, I'll make sure you never get to bang Sam!" Nebula shouted angrily.

"What? Sam is a student! Why would I want to sleep with him? Get out of here!" Ms. Pershing shouted. You glance back to the other girls, who have all reached the door as well. The four of you stand just outside of the room. You all look at each other.

"Who is the head of the... uh... Society?" You ask.

"Well, technically, both Zoe and I are heads, but if you mean the Nurturing Head... I'm actually not sure," Chris said, "I've never seen her without her mask..."

"Wait, you don't know who it is?!?" Zoe said incredulously, "It's not your... uh..."

"Who is it?" Chris asked, inquisitively.

"...Uh, nevermind, I must have been wrong..." Zoe said, slightly flustered.

The conversation was cut short by the sounds of Ms. Pershing shoving Nebula and Devoratora out of her office. Kicking the door to her office open, her eyes widened as she saw the four of you also nude. Her left eye twitched as she crudely pointed her finger in each of your faces in succession.

"Sam, expelled! Zoe, expelled! Christina, expelled! Joyce, expelled!"

She slammed the door harshly, leaving the six of you in the hallway, standing awkwardly.

"...If it's any reassurance, I never finished my schooling either..." Devoratora said. (Much later, you'd find that by "never finishing schooling", she meant, "I hospitalized my PHD professor after they called my thesis 'psychopathic exhibitionist drivel' and became a wanted fugitive".)

"Sam... why are you here?" Nebula asked, slightly confused.

"We came to get you." you said.

"Get me? What are you talking about? Don't you think I'm annoying? And have a weak jawline? And screw up everything? And leak the confidential robot designs of our classmates because I was bored? And... *sob*" Nebula seemed to get more and more upset as she listed her many many flaws. "I couldn't even solve the mystery of who the leader of the Society is! I just got you all expelled!"

I mean, she's not wrong...

You sigh, "Nebula... none of that matters... what matters is..."
