Imagine Momen-Otoko's surprise when he found a headless man sitting in a seiza inside his living room.

He had just come back from a midnight stroll when he found the intruder sipping tea without a care in the world, the liquid just vanishing in mid-air. How he managed to find his tea set he didn't know, and frankly it scared him. Had he been here for long?

Cotton balls scattered around his feet, blinking their small eyes as they took a glance towards their master. Momen-Otoko stared back at them with just as much confusion, and with eerie synchronization, they looked back towards the stranger inside the room.

"At ease, Momen-Otoko." the headless man spoke up, placing the tea cup back onto the floor without even facing him. "I've been expecting you."

"But... But this is my house."

"I've been expecting you," he repeated, ignoring him. "Please, take a seat."

Momen-Otoko decided to question the absurdity of that statement later and sat down in front of him. The cotton balls looked at each other for a second before they followed suit, taking their places at either side of him or on his lap. One struggled to climb up his puffy cotton hair before he helped it up using a hand, letting it sit comfortably atop his head.

"Now, this won't take long." the headless man assured him, coughing a few times before he straightened himself. "I apologize for the intrusion. I am known as Menimienai, principal of Yuurei Academy."

"Um... Nice to meet you." Momen-Otoko hesitantly said.

He knew Yuurei Academy. No one of their kind wouldn't. It was the first and only ghost academy in existence to this day, known to teach young ghostlings. He didn't know what it is they teach, but somehow he doubted that it'd be the same as the humans.

The question is, why was he here? Despite his childish appearance, he was far from being a ghostling. To hire him as a teacher?

"My visit here is merely for a simple request." Menimienai stated, "Join our academy."

"I'm afraid I won't be a good teacher." Momen-Otoko apologized, "Maybe you can find someone else?"

"Teacher? No, no. We have enough of them already. I'm asking you to be a student."

...

He wanted to cry.

"Excuse me... But despite how I look I'm actually hundreds of years old. I think you got it wrong." he tried to politely correct him, but deep inside he felt like sulking. This wasn't the first, and sadly it seems like it wouldn't be the last.

The cotton balls shook in mirth, to his dismay.

"We know. We made an exception just for you. You see..." he sighed, "You lack terror."

"I'm... sorry?"

Does he have to be?

"It's not that you don't have your fair share of scary stories, it's just that your scores in the spooky statistics didn't even reach average. The seniors weren't very happy." Menimienai seemed to be shaking his head, but he couldn't tell.

It was at this moment that Momen-Otoko noticed one of his fluffy friends had snuck up behind the principal, and stared at it in horror.

'What are you doing?!' he thought worriedly, watching as the round ball of fluff stealthily climbed up the unsuspecting yokai's back.

"Naturally, they reached out to us and asked to teach you the horrific ways of death. That is the sole mission of our academy." he solemnly said. "You do know about the Decade of Harmony, don't you?"

"Y-Yes." Momen-Otoko anxiously watched the cotton ball slowly creep up to the top of the headless man's head, revealing that his head was not nonexistent, but invisible instead. He didn't dwell on it too much, however. His worries were on something else.

"It was a wondrous moment for humans, yes, but for us ghosts not so much. With the appearance of quirks, seeing transparent people pass through walls just wasn't scary enough. Why would they? Some of them could even freeze entire buildings." Menimienai growled. "But not anymore."

Momen-Otoko had to hold in a wince at seeing the fluffball nearly fall from its footing.

"Quirks aren't just for living humans! Now, we ourselves are granted quirks. With this, we're able to start our revolution! Humans will fear us once again, and we will regain our rightful place in this world!"

He stood up dramatically, and with that sudden jerk he caused the fluffball to fall down with a ploof.

The cotton ball glared daggers at the principal and promptly opened itself into two, revealing shark-like fangs.

It bit him, and Menimienai screamed bloody murder.

.

"I'm really sorry!" Momen-Otoko bowed his head repeatedly as several of the cotton balls went to, sloppily, bandage the headless man's leg. The guilty fluff ball was surrounded by its fellow kin, seemingly scolding it although no sound could be heard from them.

"Nah, that's okay. I'm just surprised. It had a strong bite for something so small." the principal laughed cheerfully. "It certainly has potential to be a horrific ghost!"

He faced the little cotton balls with a smile and patted the one who bit him, now shrunk in size from its guilt. "It's fine, little fella! But seriously though, there's no need to bandage me. I'm dead, remember?"

"Oh, my friends got used to this after accidentally biting people several times in the past. The habit's stuck onto them ever since." Momen-Otoko scratched his cheek sheepishly. "Everyone, you can open the bandages now."

He was met with stares of refusal.

"Eh?"

Menimienai couldn't stop himself from cackling aloud.

"I see why they asked us to specifically teach you. You're too soft." he paused, "I didn't mean that as a pun, but that works too!"

"Sir?" the cotton yokai was baffled.

"Sorry." he coughed a few times. "Which is why I now come back to my previous request..." he trailed off, then stretched his arm out in a welcoming gesture, "Join us!"

"Can't I refuse?"

"No, not really, no. You're required to."

"... Why?"

"Well," the other ghost thought of the reason for a few seconds, "Why not?"

"You don't really have a decent explanation, do you?" Momen-Otoko tried to hold in a cringe and opted to smile, awkwardly.

"Did you just assume that I don't have a reason?" Menimienai gasped.

"You do?"

"Well, I don't. You got me."

Momen-Otoko was speechless.

"Anyhow, that's unimportant! I'm basically just here to tell you that you're expected at Yuurei tomorrow." the principal clapped his hands once, causing them to flinch. "12 AM sharp! You hear me?"

"But, Menimienai..."

The headless man responded by shoving a picture in front of his face.

Before him was a picture of unfathomable incredibility, especially for those who knew Momen-Otoko. He was looking at a picture he thought had been rid off for good. The most abominable object in all of nonliving society.

An It-That-Must-Not-Be-Spoken-Of.

"Fine! I'll go to this academy thing you speak of!" he cried tearfully, swatting the offending object away from his sight.

"I'm glad you finally see things my way." the principal grinned with a sort of sadistic glee, "Don't worry, info about you will become T-star classified information. You can mix in with the younglings no problem!"

Momen-Otoko was not amused. As if to prove his point, he curled himself into a depressed ball. The cotton balls hopped off him and huddled close to cheer him up.

"I best take my leave now." Menimienai chuckled at the sight, tipping a nonexistent hat in a small greeting, "Bonjour, señor."

He chose not to comment on that.

Once he left, Momen-Otoko eventually gathered the will to move and took a piece of parchment, a pen, and began to write.

Sis, I think I just got blackmailed into attending school.

.

This is an AU in which ghosts also got quirks like humans. They do their school activities inside UA, at midnight. The timeline is the same as Deku and the others, but we won't really see them much, if at all.

Apart from their quirks, the characters will all have common ghostly abilities, like passing through walls or solid objects.

Rules and warnings you must read before sending an OC. Failure to do so will cause your OC to be ignored and/or be given drastic measures such as being switched with another OC. Feel free to ask me questions about them or about the form, I don't bite! :3

Rules:

1. The OC form must be filled in. Do not use your own form.

2. I will only accept OCs sent via PM.

3. Please be mindful that these characters are ghosts. They're not alive. Please. I can't stress this enough.

4. For the sake of my sanity, NO ANGEL, DEVIL/DEMON, DEMI-GOD, AND/OR GODLY QUIRKS. I repeat, they are ghosts.

5. Send the OC under the title of "Yuurei Academy: (Full Name), (Human Ghost/Yokai)".

6. Due date is May 29th, though it can be extended. Don't rush! I will only look through the OCs on the due date, so don't be surprised if I haven't replied to your submission yet. I will only reply on May 29th. Thus, how early or how late you are doesn't matter. Just make sure you send the OC on time.

Feel free to tell me if you need more time :3

7. To make sure that you have indeed read the rules, write: "I will accept all stupidity that might befall or be done by my OC" in your OC submission. This is the first thing I will see in your submission. Absence of this means I won't accept.

8. This story is taking place in Musutafu. Thus, the OCs should strictly be Japanese.

9. I'm accepting 10 human ghosts and 10 yokais only.

10. If your OC is accepted, make sure you tell me from time to time that you're still reading. You can PM or review. You don't have to review all the chapters, just tell me you're still there. No need to write full-out essays as reviews either, but you're welcome to! ;3

Warnings:

1. This is a humor genre. Which means that all of the characters will be doing stupid things once in a while. Sending edgelord characters will most likely make them end up being the victim of puns and jokes from the more shameless OCs, so if you did send in one, please be prepared for them to be ridiculed in some way like all OCs (including mine. Most especially mine).

If the edgelord has a funny side, even better!

2. There will be no romance in this story. Purely shenanigans and friendship fluff. You're welcome to ship, but don't expect them to sail anytime soon.

3. There will be no combat in this story, except for a few brawls here and there by the delinquent students, but that won't be a full-blown fight either. This story is a slice of life kind of story. Focus on your OC's perks instead of their power.

4. I will reply to all your submissions whether you get accepted or not, except if you broke a few rules. If I don't reply to you by the time the due date's passed, it means that you did just that. Also, I will accept the ones I deem most interesting/fun to write and unique. Try to think of an original OC concept. The weirder, the better! Anyone wants to send me an octopus ghost that CAN be eaten by their friends?! The soul of a king who's allergic to humans?!

Remember, this is humor. (' v ')

5. In this story, the students will be categorized into two types: Human ghosts and yokais. Emitter types will be categorized under human ghosts. Transformation and Mutants will be categorized under yokais. No hybrid quirks. Please fill in the form accurately based on your OC's type.

Now with that out of the way, here's the OC form.

Name (For human ghosts, give them normal names complete with a surname. Yokai types must think of a ghost name. For example: Yuki-Onna, Inugami, Futakuchi, etc. Please try to be original and don't use existing yokai names. Google helps. Momen-Otoko is a yokai whose name basically means "cotton boy".):

Nickname(s) (Are you okay with me adding a few nicknames myself or no? Include this):

Gender(Male or female. The OC wants to troll because of their immortality and made up their own pronoun? That's fine as well!):

(For human ghosts only) Age of death(their age when they died):

Personality(I demand a lovely essay on this. Your OC being accepted or not literally depends on it. ):

Height&Weight(I accept kgs and cms as well. Go all out on this. They're ghosts, weight doesn't even affect their appearance. Want them to be weightless? Go ahead. A slime heavy beyond belief? Go on ahead!):

Hair(Do they even have hair? Do they even have a head?):

Eyes(Do they even have eyes? No pupils? Bring. It. On! However, giving your character heterochromia eyes reduces their chances of being accepted. I'll only accept if it seems legit and not put there just to 'look cool'.)

Appearance(their overall appearance. Skin tone, figure, scars, birthmarks, those kind of stuff. Want to describe your OC as only "Giant golden blob?" Go ahead! There's limitless potential to ghosts! Want them to be a walking chibi that can suddenly turn into a giant mouthed monster? Feel free! However, no "looks like (insert existing character of any franchise)" descriptions):

Attire(their clothes. Either modern or traditional clothing is an okay! What? They're literal dolphins, so they don't have clothes? No problem! Just... make it appropriate, please owo):

Likes:

Dislikes:

Quirk(The name of the quirk, type, and what it does):

Quirk flaws (basically weaknesses or the limits of the quirk. A ridiculous trait is required. For example, Momen-Otoko's quirk can let moth mutants eat his hair. Literally.):

Special trait/ability(A special trait or ability that has a relation with the quirk, but doesn't have quirk-like properties. Is often the thing that differentiates them from other ghosts. For example: Momen-Otoko's ability is to turn cotton balls into his 'living' underlings. A Yuki-Onna's trait is that she herself can melt like snow and is as cold as snow.) (choose one only, trait or ability. Traits are a physical feature, while ability is something they can do exclusively.):

(For human ghosts) How they died (events leading to their death. Doesn't have to be tragic nor detailed. Something like "Slipped on a banana peel and fell head-first" is good enough. From an illness is also fine.):

Dream goal (what do they want to achieve as a ghost? Become the spookiest? To find out what their dream itself is? No dream and just wants to finish this academy?):

Dorm room(whose dorm from among the 1-A cast do you want them to have? Want it random? Sure!)

I accept critique and flames! Feel free to comment! They help me improve! :D

Thanks for reading~
