I'm Just Part of the League (BNHA Izuku x Sister! Reader Book 2)

Ch7- Another Shared Secret

Izuku's POV
I felt a large pain in my side as I opened my eyes to see that I am tied to a metal chair. "You're awake? That was fast... Looks like I underestimated you." A looked up to see my sister...

'We're still in each other's bodies.' "What the h*ll is wrong with you?!" I dared to scream as loud as I can at my sister. Out of all of the crimes she had committed, this o's far beyond her villainous deeds.

"Y-you ran away from home! Y-you've injured my Sensei multiple times! Don't even get me started on all the damage you've caused to our school! I-I just... I JUST CAN'T!" I brought my head down as I began to cry.

"And look where all of these events had led us up to, you crying, as usual." My sister sat in a chair across from me and crossed her legs as I knew she was enjoying watching me suffer. "The Age of Heroes has fallen, Izuku... You don't have to pretend anymore."

My sister glared daggers into my eyes as the silence in the room grew thinner. "You think this whole thing is make-believe?" I asked her as I could tell that she wasn't fazed by my reaction.

She looked as if though she expected this from me. She stood back up and walked towards me holding dozens of old notebooks. A loud thump could be heard as she dropped them onto the chair she sat in.

"You think these were all make-believe, too?" (Y/N) opened up a notebook and began to read a page.

Today I just received a new patient. I could tell that there were a lot of mixed feelings hiding between her bones. But I'm worried, she'll be fixed up in no time. After all, she's just another patient that's just lost in life.

Just got finished with another patient. But I couldn't stop thinking about how my last one was a burden.

"Uh, I don't understand.?" My sister rolled her eyes and grabbed me by the neck. "Of course you don't understand! You weren't the one that got sent to therapy!" I widened my eyes as (Y/N) pushed my head against the asks of my chair.

I groaned in pain, but I still kept a shocked expression. "Ever since we started middle school, Mom couldn't help but care about my wellbeing, so she sent to talk to a stranger who thinks they know everything because they earned a degree!"

(Y/N) lost it and kicked all of the notebooks off the chair. "Talking to someone that takes you as an experiment will only drive you into madness. Just look at what I've become! I'm a f*cking masterpiece!"

(Y/N) pulled out a giant needle holding a green substance and walked towards me. "Don't worry, I already injected myself with this, too. So you're not alone!" (Y/N) kissed me on the cheek and threw a wicked smiled as she stabbed the needle in my neck.

I tried my best not to cry as the pain was overwhelming. I soon passed out due to me not handling the strong feeling flowing through my body.

(Y/N)'s POV
My diabolical laughing soon died down as I saw Izuku passing out in the chair. I winced in pain as I felt the substance mixing in with my blood. I growled in frustration and decided to quickly get the procedure over with.

"(Y/N), look, it's Kamui Woods!" My eyes died down into a calm state as I glanced back at Izuku. "Hey, Aniki, if you ever had a secret..you would trust me with it, right? We would always tell our secrets to each other?"

I looked at ourselves through the broken mirror that's leaning on the wall across the room. "Don't worry about it." I huffed as I took an old scrunched-up photo from my pocket.

I opened it up to see the last picture Izuku and I took together.  "(Y/N)..we can end all this... You can come with me." Both of our bodies started to glow green as I felt myself getting tired. "We can attend UA, together."

I've heard people telling me what I'm doing right and what I'm doing wrong. But no one has ever gotten close enough to break through my barrier. I sat against the wall as I stared up at Izuku.

I pressed the red button on the wall as the automatic transmission started playing. "Thirty seconds until fluid launch." The robotic voice over the speaker said as I sat there in silence.

I listened to the countdown as I prepared to forgo the final step of the extraction. "Giving up is what kills people; and you..you've given up your dream on becoming a hero, just to become someone evil."

A small smile appeared on my face as I recalled another memory. "Twenty seconds." A broke out into a small laugh as I felt my insanity slipping away. "What the h*ll is wrong with you?!"

My legs started it shake as they've almost given up on me. "Ten seconds. Nine... Eight..." "Don't even get me started on all the damage you've caused to our school!" I made my way towards Izuku as I traced my face.

"Seven... Six... Five..." Both of our foreheads made contact as I felt his slow breathing. "Four... Three..." The green light flowing our bodies grew lighter as our Quirks also activated.

"You... are a stubborn idiot," I mumbled as I fell to the floor. "Two... One..." I closed my eyes as I felt the substance caving its way into the room. "Extraction completed."
