Reader-chan POV

"EREN!!!! WHAT THE HELL?!??" I shouted at the top of my lungs. My shoulders rising up and down with the rhythm of my fast breathing.
He turned and looked at me, but then immediately looked down, probably in shame.
"HOW MANY TIMES HAVE I TOLD YOU TO BE CAREFUL?!? PEOPLE COULD GET HURT!!!" I shouted up at him.
Eren had suddenly transformed while trying to pick a fight with Jean...again.
I was helping with cleaning in the mess hall, my hand thoroughly scrubbing the dishes when I suddenly heard a familiar boom! A short earthquake following.
I threw the dish in the dishwater and ran outside towards the training grounds.
Eren turned his head to the side and growled deeply.
"Oi what the hell happened you brats?" I winced when I heard Levi's voice behind me, knowing Eren, and most likely me too, would get in trouble.
I closed my eyes and sighed before whirling around to face Levi.
"It was an accident Captain. Eren sort of lost control-"
"Tch, again?" He raised an eyebrow and folded his arms over his chest.
"Well, you see, he's still getting accustomed to controlling it. But he's getting it!" I rushed the last part.
His eyes, which held a bored expression, flickered to where Jean was standing.
"How did this start?" he calmly asked.
"Jean? Mind explaining?" I called out.
I saw him walk towards us with hesitant steps and a nervous expression plastered on his face.
"(Y/n) help Eren, in the meantime I'm going to have a talk with Kirschtein. Once you're done, send him to my office. These two idiots will be dealt with," said Levi. I nodded and he walked away with Jean trailing behind him.
I turned around to face Eren again and opened my mouth to say something but the words never escaped my mouth when I felt a familiar presence behind me.
I turned my head, and looked over my shoulder, noticing that Sebastian was standing behind me, Ciel standing beside him.
"So this is the other titan shifter?" ask Ciel as he lazily looked up at Eren.
"Yeah, but this moron still needs help," I sighed.
"EREN!" I shouted. His turquoise eyes met mine, silently questioning me.
"Try to get out of the titan form and if you can't then I'll take over!" He nodded and attempted to follow instructions.
"(Y/n) Are you his teacher?" asked Sebastian behind me.
"Well I guess. I mean I teach him whenever I have time the basics but he doesn't seem to improve as much as he did in the beginning," I explained, tucking a strand of hair behind my ear.
"HOLY CRAP!!! (Y/n)!!! Why didn't you tell me Eren was in his titan form?!? I could have collected a DNA sample!!!"squealed Hanji as she ran towards me.
"Well, it was sudden Hanji-" I was cut off when she jumped and landed on my back.
"You need to tell me next time 'kay?!? I'll forgive you this time!!!" she shook my shoulders and ran towards Eren as he continued to struggle to get out of his titan form.
"She's mad," stated Ciel. I smiled.
"Yeah tell me about it...EREN!!! I'm taking care of it just hold on!!" I shouted and made my way towards him.
I pulled my blades out and launched the hooks out, latching onto his shoulder blades.
I angled my body forward but twisted, placing the blades behind my head, ready to strike.
The second my blade touched the nape of his neck, I knew something was wrong. I felt it in the air.
My head turned to the left and saw Eren's hand flying towards me.
My eyes widened and I jumped back before he knocked my to the side. I landed on my feet behind him. I could hear Eren's heavy breathing.
"(Y/n)?!? Are you right?!?" Said Sebastian as he ran towards my side. I was panting slightly, probably from the sudden action. I nodded, my eyes still wide. Sebastian grabbed my hands and pulled me towards the side, putting distance between us and Eren.
His crimson eyes filled with worry searched my face.
"Are you sure he didn't hurt you?" He asked and turned to look at Eren.
Ciel was running towards us, along with Hanji.
"Are you okay?!" Hanji asked. I nodded and saw that there were soldiers already surrounding Eren, sitting atop tree branches and the roof of the buildings.
But Eren...he stood completely still almost as if he were dead.
I slowly approached him once more, until Sebastian caught my arm and pulled me back.
"Stay back. What if he hurts you?" He asked. I shook my head, placing my hand atop his.
"Trust me, he's better now. I just need to cut his nape open. He's limp he can't do anything." I said, my eyes pleading.
Sebastian sighed and let go.
Once again, I shot the hooks out and in a flash, I could hear the steam erupting into the air.
I turned and saw Eren's nape cut open. He didn't react toward it. So I jumped atop his shoulders and reached inside, ignoring the steam that hit my face.
I saw Eren's limp body stuck in the muscle. I grabbed him by his arms and pulled.
I grunted when he finally got loose and I was falling backwards. But my back never hit the floor, because Sebastian broke my fall.
Eren's titan body fell forwards and began to dissolve into steam as I placed his head on my lap. I leaned down and placed my head on his chest, above his heart.
Thump........thump........thump
My head shot up, and I began shouting.
"Someone! Get the doctor! His heart is slowing down!!"

So here's the update like I said. Please review!! Oh and I've erased the Mystic Messenger story since it wasn't as liked as this one so yeah. Thank you for reading!!!
