The misunderstood teacher (kokushibo reader x hp)

first day , first death

Y/n pov
We teacher's were then told to go to the main hall where the dining feast is being held , everyone was there except quirrell , that slimy bastard

Dumbledore- I the princepal of Hogwarts welcome you here and you need to be aware of the following rules

He then laid out some rules that I don't remember since I wasn't paying attention and was more intrested in the candles hanging above , then suddenly I heard someone giggle and stared straight into their direction

Me- pesky students laughing at me , oh i will give you something morbid to laugh at

Minerva- please calm down professor tsugikini

Me- call me Kokushibo Minerva

Minerva- ok

Dumbledore- LET THE SORTING BEGIN!!!

???- TROLL!!! TROLL!!!

Ah yes of course it's quirrell

Harry pov-
Wait troll

Me- shit! Ron! Hermione , she is in the bathroom and doesn't know about the troll

Ron- OH YEAH , WE NEED TO FIND HER

We then sneaked past the rest of the students and towards the girls bathroom, running there we suddenly heard some grumbling and some squishing noises , it was a macarbe sight to see , blood splattered every where and a huge troll sorting there with his back to us

Me- n-no , he got to them before us
Thats when he reared his ugly face towards us and smiled

Troll- hehehehe

How? Why? I dont want to die so early , I looked towards Ron and he too was frozen in fear

The troll advanced towards us shaking the corridor with each step and came to stand still in front of us as it flashed his disgusting, bloody smile

And forwarded his hand to eat us , I closed my eyes and heard blood spill and a thud

Me - I am sorry Ron....

???- who exactly gave you the permission to try and eat my son

Me - F-FATHER

Troll- aaaaaahhhhhh!!
His screech shook up the entire building

Father- just shut up
And the he did something that I had never seen before ,
He calmly walked up to the troll and by the troll's facial expression , he was shitscared , my father pulled out his sword

Father- moon breathing , 1st form dark moon , evening palace

And he cut the troll in half with his guts spewing all across the room

???- HARRY ,RON  are you alright ?!

Both - Hermione!!! You are fine!!!
Hermione- Yeah , I heard some people talking about the troll and I immediately rushed to the great hall to tell the teachers , there I found out that you two were missing and found you, b-but w-why are you two covered in blood

Hermione pov-

Seeing them in such a state was horrifying for me

???- Harry , Mr. Weasley are you alright

Professor Dumbledore said with concern in his voice

???- they are fine professor but the troll I wouldn't say the same thing about it ,

A man covered in blood and intestine walked out of behind them

My eyes widened in fear , clearly this man wasn't a man to mess with

???- you might need some cleaning job in this corridor , it's a mess

Professor Dumbledore - sure professor tsugikini

Wait that is a teacher!!!

All the rest of the students - w-what!!! That is a teacher

Professor tsugikini- Yes I am your swordsmanship teacher , I am here to teach you all the variation in combat , that exist , you shall call me professor tsugikini or Kokushibo senesei , is that understood

Draco- fuck off!!! I am not going to except a swine like you as my teacher

Professor tsugikini- Is that so

Professor dumbledore- now now , professor tsugikini , please calm down

Professor tsugikini - I am calm , i just don't know why this blond bitxh thought he was worth my time , but keeping that aside let's go to the sorting ceremony shall we

With that said we went to the sorting ceremony and me , Harry and Ron were all put into gryffindor and that blonde boy was put in Slytherin and so on
Ron- hey Harry

Harry- yeah?

Ron- are you related to professor tsugikini ? Like you and him were talking quiet a while on the platform

Harry- oh he is my adoptive father

Ron and me - WHAT!?

Harry- yeah

Ron and me - damn

Ron- well I sure as hope I don't piss either of you off , if I want to live that is

Me- oh yeah! What exactly happened

Ron- so me and Harry went out of the hall to search for you and came across the troll , the whole corridor was covered with blood , it walked towards us and me and Harry were frozen in fear , that is when out of nowhere professor tsugikini appeared and cut the troll's arm , and then calmly slashed open the troll's stomach . Watching his e.otionless face ment he had done this for years

Harry- it even surprised me

Me- so in short there is a lot a we need to know about professor tsugikini
