Sacrfical Scout (A Diabolik lovers x Attack on Titan crossover)

Eren or Ayato? Yui must decide.

Yo guys, I'm so sorry I haven't updated in a real long while but I promise I'll get more chapters done faster now. I've been really busy working on my calves.. and thighs. This is gonna be really cringy just a warning for people with vision.

* YUI'S P.O.V*

I was still sitting on the roof that Eren and I met up at. I sat there like a fool. And they're they were. Like animals fighting over a single shred of meat. Eren, was my childhood friend, my best friend, the only one who I could trust and count on no matter what the situation calls for. As well, over the years I gradually developed strong feelings for him. At the same time these thoughts raced through my head I also thought of Ayato. Why Ayato...huh? At first I wanted to rip off his head and make him feel same pain he put me through but, I no longer had that feeling. I can't explain or evaluate it honestly. Who do I truly want to win here..? Suddenly I felt my body feel weak, unstable. I was sweating like a pig. It wasn't even hot outside. I felt my limber body collapse. I was near the edge of the roof but, thankfully Subaru was there to catch me. Before I leave...I've decided....I-I chose....

*AYATO'S P.O.V*

Eren and I simultaneously began running along the tempered roofs ahead of us. Making our way to the beginning of the race.

" Well then Jaeger boy I guess it's just you and I! You should start to calm down by the way. We wouldn't want any innocent bystanders getting hurt just because of MY game. " I told Eren as I skimmed through my hair with my thin fingers.

" Fine by me. Let's get this going!" The feeble boy claimed.

My plan was put into action. We saw Reji with his left arm out. I planned on using a two whistle method. Reji's first blow of the whistle will signal Eren and I to start, essentially that's when we'll get in position. The second blow of the whistle will indicate our starting of the race. We both stopped at this tampered ugly green roof. It had chip marks all around it. We heard the first blow and started sprinting. I heard both of our loud breaths. I saw the first flag in our circumference. It was a bright yellow. There were two Titans in front of it. A five metre and a normal. I used my hand signals to Reji to tell him to distract the five metre. I now only had one Titan. I pierced through the normal Titan's nape and it shuttered to the ground of Trost. " This is getting me bored already!" I shouted.

" HEY AYATO! I SAW WHAT YOU DID! YOU CANNOT ORDER YOUR BROTHER AROUND TO CHEAT!" I sighed to Jaeger's statement.

" Have you no memory boy? I'll say it once again... It's well MY game!" I wish I could've drilled those words into his thick skull.

" TCH." Eren said with a frustrated look.

I started gliding through the streets of Trost. I've captured seven flags so far. I planted twenty. I look behind me to find Eren with four in his hand. That means there is only nine flags left. It won't be longer till I reach the finish line and that fake representation of a man will leave Yui alone. She's my property. I've even made that clear to my five brothers. I saw Eren come in my view. He was running hopelessly on sheer luck and false hope.

" Ayato tell me one thing if you can. What is Yui to you?" He questioned.

" Hmph. Why should I answer?" I stammered back.

" Stop playing so goddam stubborn and prideful! It's irritating me!" He replied.

" Why don't you guess Jaeger? I'm going to deny all options you provide regardless. Stop wasting precious time and focus on what's ahead of you!"

" Tch. Challenge me to some dumbass game and then keep all of your secrets confined."  Jaeger blurted.

We both continued to grapple onto buildings heading south to the wall of Trost. I've captured fifteen flags now. I knew Eren had obtained four. As I started to make my way to the checkpoint I see Eren already there. He had five flags in his hand. " Hmph well I guess... MY game is over now. How pleasing. We are all finished here aren't we ?" I whispered to myself. My foot finally made contact with the finish line. " Okay Eren. That was your little treat for now. Please disperse." I waved my hand indicating him to leave.

" Ayato......" Eren said with his hair in a mess. My eyes widened. What else did he have to say?

"IM THE ONE WHO WON HERE!" He screamed. Silence was the only one here at this moment. I was shocked. My brothers were shocked. So were the remaining Scout and Garrison regiments who knew about MY game.

" Uh...are you so fucking pathetic and foolish that you think you won? What qualifies you as the winner? I captured the most flags. Ten more than you. I captured the fifteen out of twenty.

" IM THE ONE WHO ARRIVED HERE FIRST! HAVE YOU FORGOT.." Eren then glanced up with his stern turquoise eyes .

" Sorry if you weren't able to hear but I said that whoever captured the most flags are victorious. I don't have time for your bullshit. Erwin is expecting me back at his office for an update on the mission. Bye for now." I made a peace sign behind me as I walked signifying my passing.

"This time I want a clean match! No cheating! Hence I would like us to have a real fight. Whoever kills the other one wins of course! I won't entitle you to it immediately but, soon enough Yui will be free of your prosecution! And I can finally be able to protect her once again. Shake on it? " Eren asked with a confident filled smirk.

" I have no idea why you're so confident. But until then...Sure." I shook his hand. Suddenly...I see my younger brother Kanato running towards me.

" AYATO HAVE YOU HEARD?!" Kanato asked acting like I should have known.

" No of course not. What happened?" I asked the fragile young boy with purple hair.

" YUI'S BEEN HOSPITALIZED!" He told me.......
