4 year old Y/n's POV
"Y/n, we're playing a game of hide & seek with your dad. Quick! Go hide before he finds you and don't make a noise ok?" (M/n) said as she rushed downstairs.
"Hmmmm, where should I hide. Oh I know! I'll go to the roof (don't question how does a child's mind work)."
I carefully climbed up the roof and got comfortable, drifted off to sleep after 10 mins since it was kinda cool at night.
Timeskip
"Kid, wake up." I heard someone said as the person softly nudged me.
"I'm awake, I'm awake. Who are you and where are we." I asked the man.
"We're on top of your roof and my name is Naomasa Tsukauchi. You can call me whatever you want as long as it makes sense. Hold on tight, I'm bringing you back down" he said as he pick you up into a piggy back ride.
"Can I just call you Tsu-chii? It's cute" I asked as I finally made up my mind.
"I came up with something worse like Sherlock or Naosama but oh well"
As Tsu-chii carried me down the stairs, he covered my eyes to hide something.
"What is it, why did you cover my eyes?" I asked
"Let's just say the scene is not something a child should witness." he replied
Being the curious kitten I am, I somehow managed to jump off his back and see what he's hiding. What I see next was definitely unexpected, right in front of the door, a large pool of red liquid is present and I see dad and mom lying on the ground with another weird looking Sherlock surrounding them.
"Like I said, you shouldn't be see this." Tsu-chii said as he tried to hold me back. (tried)
I escaped his grip and walk towards mom and dad, seeing them there on the ground made something inside me snapped. I understood what happen almost right after, that's why mom and dad forbid me to watch the news on tv. I started to analyse the situation in front of me and came to a few conclusions.
"Naomasa...(only when your serious you don't use nicknames)" I called with a dark aura surrounding me. "You should already know that my parents are murdered by most likely a villain. But from looking at the damage that's done, it's not possible with only one quirk, it's either a villain with multiple quirks or a few villains did this. My mom came to my room and told me to play hide & seek out of nowhere at around 10:00 at night, now I understand why. When I got up to the roof, I'm certain that no one left the front door in the next ten minutes before I fell asleep, this damage can be done in less then five minutes so I say there was a person who can warp or teleport them away and my parents died about eight minutes ago seen as it's 10:43 at night right now... am I right Naomasa." I finished as I turned around to see a surprise look planted on him.
"H-how did you analyse everything so quickly." stuttered Tsu-chii.
"I think I just got my quirk maybe due to the shock when I saw the parents' dead bodies. I will say I got my mom's quirk which is high spec but I'm not sure if I got dad's quirk or not yet." I answered.
"Yea, I will say the same and I think your deduction is quite accurate, you even picked up a few points I didn't pick up." the other Sherlock said as he walked towards us.
"Y/n... I need to tell you something," Tsu-chii said so he can get my attention, " your parents' last words were "help us explain what happened to Nezu and he'll take care of Y/n. Make sure she lives a happy life, lastly tell her that we're sorry about lying the whole hide & seek thing and that we will not be able to stay with her physically but only spiritually." Tsu-chii finished as he walked over to me and gave me a hug.
I can feel that tears are starting to form and I quickly rubbed them off.
"I'm ok, Tsu-chii. And also you should check the cctv footage, it probably caught most of what happen here." I said as I pat his back as if I'm the one comforting him.
Very little time skip
After checking the footage, we found out that I was right, there was a guy that looks like mist warped a weird looking bird and another man with a hand cover his face. The fight between the bird and my parents were brutal but I endured. I found out that the villains were part of the LoV(league of villains) from Tsu-chii and made up my mind that I will take revenge on them in place of my parents.
Bigger time skip
Principle Nezu (you call him a talking hamster from time to time)took me in and now I secretly live in UA dorms seen as no one lives there yet. You kept training to prepare yourself when you will finally get revenge on the villains but nothing much happen in your life because you did not go to school after your parents' death until...
{A/N: Yaho~ Just in case if you're wondering, you're other relatives are either dead due to various reasons or are currently not in Japan. Also, don't hesitate to comment on what you think nee?}
