The Beast goes To School

the quest for answers

Today I was leaving on a quest to the center of the Yggdrasil continent,apparently there are a lot of Grimm monsters that need to be cleared out as soon as possible so they decided to send both me and aella there

At first koro sensei didn't agree since the exams were coming up and I was reluctant myself to do socBut when he came back he told me this

"After talking with the headmistress I understand better the situation,though it will be a handicap for you as a student but

It will be a life changing experience as Y/n Oga"he said in a serious tone hidden behind his smile

I nodded as I knew I shouldn't ask anymore questions

I looked over to the helicopter to see aella standing there as she took a glance at me before she left out of sight

"Are you leaving for real?"asked hollow

"Yeah,but don't worry I'll be back and I'll bring you a skull of the rarest grimm I find"i said

Then from afar i noticed ryuko running towards us as she was shouting

"WAIT!!"

She then walked up to me as she was then reaching out for her pocket and pulled out a much smaller version of her scissor blade put in a necklace,she then put it in Grimm's neck

"Keep it with you okay?as long as you have it,you two will always be together"she said

I looked at her with a look that spelled confusion

"Just leave it with him,you can give it back to me when I come back from a trip I'm going to"she said

I nodded and smiled as I waved the others goodbye as I got into the helicopter

+++++++++++koro sensei PoV+++++++++

As I watched the helicopter leave I could only wish that he could find the answers he was looking for even though it might open up a whole new world for him and he might not even be interested in class anymore and I do not wish for that

Ryuko who was standing besides me poked me as she gave me a piece of paper which I opened as it said

<come to my house tomorrow,she wants to talk to you>

The next day I followed her as we entered her house to see the headmistress also there but also in a pyjama outfit

"Oh,koro sensei now that Y/n has left it is time to resume our discussion"she said as I nodded

+++++++++++++flashback++++++++++++

I was in the headmistress's office complaining to her

"But my goddess!he needs to study for the exams!he will fail if he goes on another quest"i said

"Koro sensei,this quest will benefit him more than these exams ever will"

"How?"

"Y/n isn't only made of void

He is also tied to an old world which is now in an alternate dimension to ensure the safety of humans,I will explain it to you later did I make myself clear? "

"But still..."I said looking down before i looked up to face her

She was staring at me as if she could reap my soul any moment she want

"I said did I make myself clear?"she asked

"Yes"said koro sensei as i remembered what tied us both before employer and employee

Goddess and her subject

++++++++++++current time+++++++++++

"I'm sorry to surprise you but I have been living here for the past few months as I found it to be quite enjoyable,please have a seat"she said as she materialized a tea set with cakes  out of thin air

Ryuko sighed

"That's the fourth tea set she creates in the house this week"said ryuko under her breath

"I heard you"said the headmistress before her attention was back to me

"Help yourself,now the reason I sent him there is quite simple

Have you noticed that I was too kind with the rejects from time to time?"she asked

I nodded

"Talk to me normally or I will cut your pay for the next three months"she threatened me

I nodded as I was shaking

"I have noticed that,you haven't done this ever since I joined this school and even before that I presume"i said

"Yes,that's because Y/n is my son"she said nonchalantly

I spit the tea in shock

"YOUR WHAAAAT?!"I asked

"Yeah I expected this reaction,I am the mother he is looking for,he doesn't know it yet
Normally I wouldn't care about the rejects or probably

The world in general

This world is nothing more than a sandbox I created for my son

I sandbox which could entertain me,so everyday when you wake up,remember that if you are all still alive it's thanks to Y/n

But I'm not saying this so that you will worship him or treat him like he's above you,by all means keep talking to him the way you are doing it now,I still want to judge people

Before everything else I want him to be happy

To study,meet the love of his life,to grow and give me grandchildren

And the rejects are an essential core in this with you as well

But I'm getting off topic

I know you may be asking yourself 'how can she have a baby if Y/n is made of void?'the answer is

The pale king and white lady had many children to spare and unfortunately they were all dead and the vessel they chose was starting to weaken

So we made a deal

I would recreate hallownest from scratch and they would give me one of their children

After getting one of them

I mixed in his soul with my essence which fused with the void,the people of the other dimension were all chanting in a ceremony celebrating his birth

But then things happened and I gave him to oga tatsumi

And this is the whole story,but I can read your mind

Normally hearing that their life depends on a single child would wreck the mental of anyone

But you're not feeling that am I right?"she asked

"Exactly,you see,even though we were all created in a sandbox for Y/n,you still gave us purposes In our lives

And mine is to make sure y/n can explore that sandbox the best he can along with his other friends"said koro sensei

The headmistress giggled

"You know,I did the right choice choosing you as my chosen mortal

You are someone with a mindset that does not stray,even though you are a pervert,you would still never in your whole life think of doing lewd things to your student

That is why you are the only mortal I can trust besides Y/n's father"she said

"You honor me with your kind words,but I can't help but wonder what may Y/n be doing right now?"I asked myself

++++++++++++++Y/n PoV++++++++++++

I was standing on top of a defeated aella with nine of my tentacles out as I looked at what was in front of me,it was a giant gate inside the mountain we crashed into during our fight

"What the hell is that?"I asked

"Grii?"answered grimm
