The Clad of Black Wings, or how I like to call them "Flying Monkeys" are a huge threat that I need to get rid of as soon as possible.
They are insane cultist who worships the devil himself, from the information I've gathered about them so far from the ones that I have eliminated.
Apparently they are currently conducting experiments on children to give them artificial abilities and plans to use them as weapons.
And they had already began this operation years ago. They would either buy or forcibly take children from their families.
Yuzuki: Unforgivable! I can't take any chances.
There is a possibility they would target Kaneki and his friends and family. After all he was kidnapped by them when he was a kid once, and they would be interested in a kid that was able to kill 19 of their fellow cultist.
I'm on taking that chance.
So during the day when Kaneki wasn't at my house helping with the cleaning I began to do some research.
I had my own pocket dimension where I do my preparations, there I began to do use all the information I got to find their base.
Yuzuki: Sigh~ this is not easy.
But with the limited information I got, It was very difficult.
Days had passed and we finished cleaning my home and I still couldn't find any good information.
After we had finished cleaning my house, and I began to train him.
Yuzuki: alright let's see your aim, shoot this can off this stump.
Kaneki: Okay!
Bang!
Thud!
Yuzuki: Kaneki?!
Surprisingly the kid was sent crashing to the ground, his mother's web gun had a strong recoil.
Kaneki: Ouch~ that hurts!
He wasn't very good at handling the gun, the recoil was too strong for him.
Thud!
Thud!
I've watched him fall over and over again but he just wouldn't give up. He only stopped when the time we had was over.
Kaneki: Thanks for the training Senpai! I'll see you tomorrow night!
Splash!
Although I planned to do research, watching over Kaneki will take up more time. Leaving me little time for my search for the flying monkeys base.
So on the next nigh, I decided to get him a gift that could aid in his training.
Kaneki: Ouch~ it hurts. Man! When will this stop happening to me!
Yuzuki: you'll get used to it, the recoil of your web gun is pretty strong. In fact too strong for your small body. But remember keep a tight grip on your gun, last thing you'd want is your enemies getting a hold of your weapon.
After I've given him that advice I gave my gift to him.
He was a bit surprised and a bit mad, he probably thought I was not going to teach him how to use real guns.
But after reassuring him, he accepted the toy guns.
He then stopped training with me for two weeks and "trained" with his friends using the toy guns I gave him.
And during these two weeks.
Yuzuki: Hmm... These guys always go around here?
I've continued my search for their base, and found quite a few things.
One of them being that the flying monkeys I've killed so far in Japan were all in places near mountains.
I suspected that their base would be somewhere in a mountain, but considering there are thousands of mountains in Japan finding the base in them was no easy task.
The 2 weeks of looking through the information I got, that was the only lead I ever got.
Yuzuki: Damnit, if I don't do anything he would get involved with them! I don't want that to happen!
I was very stressed, I feared that Kaneki would get involved with them. They already took away his mom from him I can't let him get involved more!
I was very desperate to find and eliminate them all as soon as possible, but Kaneki was already waiting for me, so I didn't have any choice.
I know that he had improved since last time, but I know he was still not ready to use real guns. So I given him a nearly impossible task.
That was that he has to hit me with at least one foam bullet from his toy gun.
The challenge was simple and difficult. With the catch being I'd be doing the same thing but if I hit him the training would be over.
It was mostly an excuse to get more time to search for the base, but also to test him.
So we did exactly that.
Kaneki would get upset every time I shot him and would leave.
As much as I hated to do that to him I'm doing it for his sake.
I continued to search for the base but there was no luck, days turned to weeks and still couldn't find anything. Until...
Kaneki: Man! Senpai you're just that good at using guns huh?
Yuzuki: Yup, it will take you years to surpass me. I am number one at shooting after all.
Kaneki: yeah yeah. Oh yeah! I've actually watched a new Knight Rider today, it was spy themed.
Yuzuki: that's nice, what happened?
He talked about a Knight rider series so much, I wasn't really interestes until...
Kaneki: they were about to lose them until they attached a tiny tracking device on his car!
That sentence had given me an idea.
In the following days I worked on making my own tracking device.
After a while I was able to complete it and it worked perfectly.
It was a small robot that looked and has the size of a mosquito, it would fly and embed itself inside the skin of it's targets.
After I finished it and did my challenge with Kaneki, I decided to use it.
I had already identified one member, the usual species that would be a flying monkey. A rich Arch-Demon.
I've sent my robot to that flying monkey without him noticing, and.
Drill~
???: hmm? Must be my imagination.
After it had successfully embedded itself I've began tracking his movements.
After a few more days of challenging with Kaneki and tracking I made the decision to retire as an assassin.
Querxes: Finally! I could rest easy now! Please live a better life okay?
Kirin: I don't know what made you retire, but I'm glad that you are.
Robecca: Yuzu. I'm so happy for you.
Needless to say all my sensei's were happy, but they didn't know about my last "mission".
Kaneki: Yay! Senpai will be my teacher in the future!
Kaneki was also happy thinking that I would become his teacher in the future.
Seeing his happy face made me guilty, that was because my last "mission" was to eliminate all of the flying monkeys, I doubt I would come back alive.
Just in case I've prepared a will that would make Kaneki inherit all my belongings including home.
On our last day of training together, I was hoping that he would hit me but.
Kaneki: dang it!
Yuzuki: it's alright... There's always next time.
Kaneki: Yeah you're right. See you next time Senpai! Even if you're retired you'll still teach me right?
Yuzuki: Yeah...
Kaneki: See ya!
Splat!
As he left I felt a huge sense of guilt, seeing that happy face was too much for me.
And so at the next night at midnight.
Yuzuki: Time to go!
I began to run towards the base.
The Flying Monkey I tracked proved my suspicion, the base was inside of a mountain. I knew there was going to a lot of them so i brought a bag that has a portal to my armory, which holds all of my guns.
After a few hours of running I found the entrance to the secret base.
Yuzuki: this is it...
I hesitated for a moment, but.
"Yuzuki-chan!"
"Yuzuki!"
Memories of my friends and family came into mind and I was filled with rage.
"Senpai"
But the memories of Kaneki gave me a sense of duty.
Yuzuki: I won't let you end up like me.
Without a second thought, I went in and begin my massacre.
Bang!
Punch!
Pierce!
???: C'mon Kill her! She just one girl!
I moved quickly, not letting a single one of them hit me.
I used my guns and killed many flying monkeys near the entrance, I continued to go up the higher floors killing everyone getting in my way.
But when I got to the 10th floor everything went horribly wrong.
Yuzuki: Die!
Click!
Yuzuki: are you kidding me?! Not now!
The gun I was using jammed and that small opening led to my defeat.
Bang!
Yuzuki: AAAAARGH!
Crash!
I was shot point blank and was immediately knocked down with a punch that followed.
Arch Demons were naturally physically stronger than humans so when that punch landed it broke many of my bones.
And I crashed onto the wall violently.
They began telling me some stuff but my ears were ringing so I couldn't hear them, I yelled out saying "I'LL KILL YOU ALL!"
After I said this, they all began to laugh and as they walked closer I knew they were going to use me as their experiments.
That was when...
Slash!
???: What the?!
Kaneki came to save me, he came with his Katana and cut many of them down while wearing a mask covering his face.
In mere seconds he had wiped out all of the flying monkeys that we're near us.
Kaneki: Senpai! Get up! Let's go!
I was both scared and furious at Kaneki, why was he here? How did he get here? Did he know about my plan?
Many questions came into mind but he couldn't answer, as we were making our escape.
I still couldn't believe he was there in the base, but as we were running trying to escape.
???: Get them!
Yuzuki: !!!
A flying monkey had a rocket launcher and aimed it towards Kaneki.
Yuzuki: Kaneki!
Kaneki: Senpai!
With what remains of my strength, I jumped to cover Kaneki.
Swoosh!
Boom!
As the missile exploded right beside us, we were both sent flying.
And once again.
???: Sigh~ to think two kids killed hundreds of us in a matter of 20 minutes.
???: these two would be good experiments.
They were all talking about turning us into experiments. And then...
???: wait that sword, doesn't it fit the description Lilith-sama told us when he tried to kidnap a kid a few years back? And the kid he tried to take killed his group after they killed his mother?
???: hey you're right.
They unme recognized Kaneki.
???: He would be perfect! We can use him as a vessel!
They changed the subject, they were no longer planning to use Kaneki as an experiment.
But a vessel for the devil himself!
I didn't want that.
Yuzuki: Like hell.
I came to kill those flying monkeys for revenge and for Kaneki, but because of my vengeance Kaneki gotten involved.
Being turned to their experiments is a horrible thought, but turning him into a vessel was too much.
I will not allow that to happen. I will protect you kid.
Yuzuki: No matter what.
I was definitely scared when I first came to the base, I knew I wouldn't see everyone again. But at that moment I lost all fear.
"Yuzuki!"
"Yuzuki-chan!"
"Senpai!"
I could hear the voices of my friends, family, my sensei's and Kaneki in my head.
As I stared at them, I made a finger gun with my hands and pointed it at the flying monkeys in front of me.
???: Hahahaha! Has she went insane?!
???: What are you gonna do? Shoot me with imaginary bullets? Hahahahaha!
They were all laughing at me, but I didn't care.
Yuzuki: If you want this kid, THEN YOU HAVE TO TAKE HIM FROM MY COLD DEAD CORPSE!
???: Hahaha! She still has some fight in her!
???: let's give her one shot, I fill a bit bad for her haha!
While they laughed, I only said one word.
Yuzuki: Bang.
With that one word.
Pierce!
???: What the?!
???: No way?!
???: how is this possible?!
Pierce!
Thud!
I began to change, red molten metal began coming out of my body and bullets made form this metal shot out hitting the flying monkeys in front of me.
I was confused but stood still, and in seconds my entire body was covered in molten metal.
The metal mostly concentrated around my arms, face, upper body, legs and back.
And after that they began to crack and explode.
Crack!
Boom!
After the explosion happened, the metal that came off disintegrated.
I immediately went to check on Kaneki, but when I saw my hands I was in complete shock.
When I looked at a reflective surface, I saw wings, claws, a tail and horns. The form I took was of...
A Demon Knight.
