Chapter 12

Y/N POV:

Y/N: *YAWN* Dammit these women are gonna be the death of me...

I sat in the teachers lounge getting my coffee. I put everything in, 3 spoons of coffee mix and 5 spoons of sugar, as usual and 4 waffles. I wasn't really hungry so I lightened the load today. I tried to pick up the coffee with my right arm. But I couldn't as all that remained was a stub. I remember that killing the beast cost my forearm. I sighed and looked at my stub. This was going to be a little weird from now on.

I was about to grab the cup with my other hand. But my stub started to burn. I gripped it and gnashed my teeth. I looked to my arm seeing the same black mist from the night before forming and extending outward. The mist started to clear but in its place was a black Grimm like arm. Claws on the end and all. I looked stunned at the new development. He heard talking down the hall getting closer. 

Y/N: Scarab cover it!

Scarab: On it.

A blue gauntlet like arm with claw outlines on the actual claws extended outward and covered the arm. The moment the gauntlet had complete formed Oobleck and Peach entered the room. They looked towards me as I waved with my now robotic covered arm.

Oobleck: Hey we heard about the arm. Did you use the scarab to do that?

Y/N: Huh? Oh! Yeah, yeah I did. Hehe, umm it got really weird with not being able to use my right arm so I did this in order to maximize... efficiency?

Peach: Are you ok Y/N?

Crap they might know something is up! I got to think and fast. I got it!

Y/N: To be honest not really... It's the anniversary of my mom's death today. I'm just a little shaken is all... I guess it's just a lonely time of year... 

Peach: That really is a shame. If you need anything don't be afraid to ask.

Y/N: Will do.

Oobleck: Young Y/N, would it be alright if I were to ask a favor of you?

Peach: Honey, maybe we should leave him alone today.

Y/N: No it's alright. I need a distraction anyways. What do you need?

They looked at each other for a second. Peach sighed and stepped forward.

Peach: We need someone to take care of our classes while my husband, Zach and I head out for a day off. Ozpin said it was fine as long as we get someone to take care of our classes. Would you mind being a substitute in our stead?

That would let me spend more time with the girls as well as extend the periods of the children to fight Grimm, plus I can put all lessons into one big mash-up.

Y/N: You kids enjoy your fun. And give little Zach a tickle from me.

I smiled as Peach gave me a hug and walked around the corner with her baby boy Zach in her arms.

Peach: Go ahead he's all yours!

I started to tickle little Zach as he laughed and kicked in the air trying to get away from the tickles.

Zach: Blaboap!

Y/N: Heh, cute.

Oobleck: Thank you Y/N, we will make sure to get you something for your troubles.

Y/N: No you really don't need... aaaand they're gone...

I chuckled to myself and sat back down drinking my coffee thinking of how to mash the lessons together when Glynda walked in.
