"Nezu! You're in I thought you just ran away haha!"

Present mic beamed at the sight of the little rodent happily skipping though his office door, nose twitching happily.

"Hello! Care for some tea?~" nezu jumped up on Mic's shoulder, holding onto his head for some stability. Mic chuckled, Nezu had been acting strangely lately but the pro hero was just glad he was back to himself now.

"No thanks! You got me worried and all when you suddenly disappeared from your office, we were this close to sending out a search party!" Mic held out his fingers to gesticulate his statement; all the whole he was yelling cheery hello's to students passing by in the corridors.

The rodent waved off his concern "oh silly I just went to check on some of our students who've been having a rough time! You know with all these strange happenings.."

The voice hero felt a chill go down his spine, a sudden cold sweat dribbling down his forehead "y-yeah... I was thinking about that actually, maybe we should set up some therapy for students wh-"

"Kac- Bakugou!"

Nezu cut of Present Mic mid sentence, springing off the hero's shoulder and onto Katsuki's shoulder who was walking alone towards the bathroom.

"Gwah!" Bakugou who looked to be in his own fanciful world yelled out and pushed Nezu off him, stumbling over his own feet in the process.

"Careful kid! You alright Nezu?" Mic exclaimed, catching the rodent before he hit the floor.

Katsuki looked terrified yet confused at the same time, heavy eye bags lining his blood red eyes - skin speckled with blemishes and tacky uniform.

"I'm just fine! It was my fault for making him jump in the first place~" nezu flicked his tail in the air, jumping back onto the floor while looking at Katsuki though black eyes.

"The poor thing seems very paranoid... can I help you at all Bakugou?"

The blonde quickly dismissed the offer "j-just leave me alone! I don't need your help" he panicked and scurried off to the bathroom, a little uneasy about Nezu's strange grin and hollow stare.

"Ho ho~ I think he's the one most in need of therapy" the rodent laughed, watching the door swing shut. Mic followed closely behind, laughing awkwardly at the thick atmosphere.

"Maybe you're right Nezu.."

"I'm always right! Anyways do you know where I can find Shota?" Nezu stopped outside of class 1-A, not seeing the teacher anywhere. All the students were conversing in their own little groups while waiting for him.

"I'm not sure, maybe in the teachers lounge? I'll go check for you!" Mic beamed while running off before stopping suddenly at the sound of Nezu's voice again.

"Wait! Do you think you could do me another favour while you're at it?"

"Sure anything you need, I don't have any classes to teach this morning"

A smile slipped onto the rodent's face "if you go to my office there should be a box of small electronic devises..." he started to explain. The blonde raised his eyebrow, intrigued by what these so called 'devises' were for.

"Take them and place each one around the security gates and surrounding this building please~ it would be a great help" Nezu waved off the teacher, hopping into the classroom while Mic stood there rather confused - however he chose not to question the principle today.

After all no one wants to get on the satan rat's bad side.

"Alright class! Listen up, Your teacher isn't feeling well at the moment so I'll be teaching you"

All students looked in bewilderment at the rat, his little nose twitching as he hopped onto the beak so everyone could see him.

"Being taught personally by our one and only Principle! It's an honour!" Iida made it his personal task to quiet everyone down, sitting robotically as usual. Sometimes others wondered if the boy really did have a stick up his ass.

Nezu giggled, his black eyes glowing as he stared at the class.

Those sinister black eyes... they seemed somehow familiar?

"Now students, I'm sure your teacher will turn up any time soon... also we're expecting a visitor. He's here to teach you a few things" nezu smiled, a strange cold air filled the room as he did.

'I've got a bad feeling about this... something off' we're the thoughts of many students in the room as they stared at the rodent.

He was silent.

Just staring with a blank look.

"Uhh... Sensei? Who's the visitor who's coming to teach us?" Uraraka was the first to break the tension, her voice uneasy.

Mina looked at everyone with worry, seeing even Bakugou's face drained of colour.

"Ho Ho~ just cute little Tamaki." Nezu's face looked like it glitched when he talked, body suddenly becoming contorted before it merged back again in a second.

Only a few noticed, but it was enough to make them fully panic now.

"I-Im going to the bathroom!" Kaminari yelled out suddenly, the poor boy felt as if his heart was about to thump out of his chest.

"Denki!" Sero yelled as he sprinted to the door. But however much he pulled and yanked at the handle, it only rattled on the hinges and would not open.

The electric user looked at the principle in hidden terror "sit back down Denki... why so scared I won't bite" a small giggle escaped his lips.

"Why'd you lock the door Sensei..." Denki's voice trembled. The room fell silent again, quiet enough to hear a hummingbird's whisper.

Nezu's tail whipped from side to side "Tamaki should be here any minute, in the mean time shall we play a game?" He purposefully dodged the teen's question.

Silence once more. "Kaminari sit down." The principle demanded, however the blonde was frozen in fear, his feet would not move.

Nezu's eyes narrowed before a sudden strong force swept the boy off his feet, pushing his body at speed towards his desk and forcing Denki to sit.

"now... let's start" he grinned, ignoring the surprised screams which racked the classroom.

"Shut up! Jesus fucking Christ I don't know how Aizawa-Sensei does this every day" 

Everyone stared confused at their teacher, his voice had become more high pitch now - a slight echo ringing on the end of each sentence.

"Fuck sakes this form is really uncomfortable, I hate it" Nezu's face scrunched, however it was brutally apparent that this wasn't Nezu...

"Trying to keep all the body parts together is sooo tiresome~ Aizawa-Sensei really did a good job at dismembering your principle hehe"

"Sensei... what are you talking about?" Momo shakily questioned, her face pale.

"Oh! Looks like Mic has finished putting up all the quirk suppressants around the school. What a good teacher, a shame he has to die really..." he giggled strangely, looking out the window with glowing eyes.

Suddenly there was a knock upon the door, Nezu's ears perked.

"Tamaki- Sempai!~" 

Instantly the rodent's body started to float, again everyone screamed as he emitted a dark green glow before a blur of light left the principles body.

"Aghh, that's so much better!"

Izuku appeared above Nezu's lifeless body,  to be honest you couldn't really recognise it at all. His tail lay separated from the body, fur peeling off his face and ribs to show dry bloodied organs and broken bones.

"What kind of sick joke is this!" Katsuki screamed, looking at the the glowing body of the boy he murdered many moons ago.

Izuku appeared in a gruesome form just for the fun of it.

He looked the exact same as that fateful night he was murdered, torn and tattered UA uniform sagging on his bleeding back - deep red holes where his wings were. His face was purple and swollen, black eyes leaking blood to make a horribly vivid image.

"Come in Tamaki-sempai!~ let's get this party started!"
