It has been two months since that incident, the police couldn't identify me but they managed to link this case to the one of the salary-man, a profile started to slowly appear for them. A young man with a quirk that allowed him to move at great speeds and control light.
That didn't make me feel threatened, they are looking for a man, they can't possibly know I'm just a really tall 11-year-old child. After a few weeks, their investigation still went nowhere, meanwhile, I kept training, only using my quirk when no one could see me.
Hiding like this is really hard, especially since in these modern times surveillance cameras are quite common, slipping into the backstreets unseen is hard, but they provide good training for my observation haki so I can't complain.
After training my quirk for a while I finally managed to get the hang of it, I couldn't hit anything at the speed of light, unlike kizaru I wasn't an absolute beast when it came to physical power. If I attempted to do so I would hurt myself more than my enemy.
Thankfully devil fruits are easy to control with enough practice, and I don't need a short grandpa to tell me how to use my power. Currently, the strongest kick I could deliver was enough to snap a tree in half, but it hurt a lot.
When I tested my limits I did so by slowly ramping up the speed of the kick until I almost broke my leg on a tree. My limits would change the stronger I became, so I wasn't too worried about it. I also needed to concentrate so my kick would be solid.
In the past few weeks, I also took to another hobby. It lead me to carry some more practical tools on me, like a rope.
In front of me was a masked man hanging upside down from a fire escape ladder, he just attempted to mug another civilian, I tied him upside down after knocking him out with a kick to the temple.
I didn't really care much for the safety of villains, I detest them, always acting without any regard for their fellow humans. Some may have excuses but many are just scum. Like the one in front of me.
The least they can do is provide me with battle experience. Even then I need to completely turn off my haki while fighting them, otherwise, they wouldn't be able to do anything.
To hide my face I just use a pair of gold-amber tinted sunglasses and a fake stubble. For my "costume" I just wore a yellow suit and white shoes. Obviously taking inspiration from Kizaru himself.
The police picked up on my activity, they gave me the nickname "Yellow Flash" for obvious reasons. At least they didn't call me Kizaru (it means yellow monkey). I only operate at night, I use my time wisely, I never waste more than two hours on hunting down villains, I still need rest, my body is still growing.
Anyway, after checking for cameras with Haki I use Yata no Kagami to reach a payphone and tell the police of the subdued villains' location.
My nights usually end here, but as I was going towards the orphanage I noticed a distinct smell of Iron, it was most definitely blood.
I turned my haki to the maximum to see a man getting stabbed in the middle of the street. Without waiting I turned into a beam of light, reflecting my way behind the aggressor and used the blunt Ama no Murakumo to deliver a fast strike to his side. Sending the villain crashing through a wall.
The villain was most likely severely injured just now, but I didn't have time to be concerned about him. I quickly searched the victim for a phone and called an ambulance and the police.
After doing that I took a glance at the obviously deranged villain, he didn't bother to wear anything to cover his face. He looked familiar, so I stepped closer to him. I now recognized him as the one that murdered the old Allan.
I decided to make sure he would get apprehended, I wasn't going to kill him, that wasn't a good way to deliver justice.
With my haki I felt him twitch, apparently he wasn't injured enough, when I was a few steps away from him, with my hands in my pockets, he pounced towards me.
I look at him with disdain, did he take me for an idiot? Laughing maniacally he tried to stab me in my chest, I didn't bother reacting to him.
He had a look of crazed elation when he saw his knife about to go through my chest, that look quickly changed into confusion when he couldn't feel much resistance as the knife went in my chest, I simply raise my leg and crushed his head down with my heel.
I used the appropriate force of all of my strength to knock him out, the man clearly had some sort of strength/endurance enhancement quirk, he was undoubtedly injured earlier but a normal man would have been put in the hospital.
After making sure the villain wouldn't be getting up, I heard sirens and booked it.
I definitely didn't want to deal with the police.
Unbeknownst to me, a camera caught the whole exchange.
