all might: excuse me doctor?
doctor: ah yes all might what is it?
all might: do you know where a woman called Miku is currently, she messaged me saying she went into labour
doctor: what was her last name?
all might: Yasha
doctor: oh, i'm sorry all might, but she died during labour
all might: no
i fell to my knee's as tears fell from my eyes
doctor: but her child survived, a baby boy
i looked up in shock
all might: may i see him
doctor: what is your relation to miss Yasha?
all might: i'm her lover
doctor: okay, follow me
i followed the doctor to the room where multiple babys were sleeping
doctor: he's on the left there
he pointed towards the boy
all might: thank you
he left as i walked up to the boy
all might: he's beautiful
i looked at his wrist and saw a name tag saying y/n
all might:don't worry Miku, i'll take care of our baby boy
i walked out and talked with the doctor again about getting custody over y/n, after filling out some forms i went back to y/n and picked him up in his blanket and walked out with him
time skip, y/n pov
it had been 5 years since my birth, dad told me about mom and how she died during my birth, i felt it was my fault but dad and his friends tell me otherwise, i had manifested my quirk at this point, dad had decided to hide me from the public until i'm old enough, i didn't really care
all might: y/n, your old enough that you have to join a school
y/n: okay
all might: your gonna start at a primary school tomorrow
y/n: okay
all might: y/n i always wondered why your not very talkative
y/n: i don't know
all might: i hope the school helps
the next day
all might:there you go y/n, have a good day,i'll see you in a few hours
y/n: okay, bye dad
he jumped away as i was taken inside, i saw a lot of kids in school uniforms, i was just in an alternate version of dad's bronze age costume, without a cape and with black boots not white and short sleeve muscle shirt instead of the full top
kid: hey miss why is he not in a uniform, i wanna not be a uniform!
teacher: i'm sorry but he's new, introduce yourself y/n
y/n: h-hey i'm y/n yagi
kid: whats your quirk?
i was told by dad to keep my quirk a secret and just tell everyone its a strength and speed boost
y/n: its a strength and speed booster,but i don't use it much
kid: why not?
y/n: i damages my body if i use it intensely
kid: sounds just like all might, but without the damage, he's so cool
everyone else: yeah he's cool
y/n: y-yeah i guess
i'm gonna hate this
time skip
i was the last in the school talking with the teacher
teacher: i still can't believe allmights son is studying at my primary school!
y/n: yeah but please keep quiet about it, my dad hasn't revealed my identity to the public
teacher: your secrets safe with me
y/n: thank you
all might: y/n my boy! i'm here to pick you up!
y/n: okay, bye sensei
sensei: goodbye y/n, goodbye all might
all might: goodbye
i got on his shoulders and we jumped back home
time skip
it was the weekend and i was just sitting around bored, dad had a day off which was rare
y/n: dad i'm bored
all might: hmmm? well since your quirk manifested, you should train it ,if you don't you won't be able to use it without damaging your body
y/n: well how do i train it?
all might: you need to distribute one for all around your body and only focus it into one spot for full power, not for every movement
y/n: what?
all might: i guess you need a trainer, who could it be?
y/n: how about uncle torino?
dad shuddered at the mention of his name
all might: are y-you s-sure?
y/n: i mean, your making no sense and he trained you so yeah
all might: okay, i'll send him a letter
time skip
i was currently on the floor doing push ups with grand torino on my back
grand torino: come on y/n keep pushing!
y/n: Hai!
i kept pushing to the point i couldn't keep going, i got up and faced grand torino
grand torino: now, i heard toshinori told you what to do but he made a mess of the explanation
y/n: yeah
grand torino: well, you need to let one for all flow in your body, and keep that flow constantly, and you'll be able to move like toshinori
y/n: right
grand torino: now concentrate
i closed my eyes and felt one for all come to life in my body as it began to flow, i opened my eyes as they flashed blue with a white shine around them
grand torino: good, now then!
he began dashing around trying to hit me, i started bouncing around the room matching his speed, he went for a kick which i blocked, i countered with a punch knocking him back from the air pressure alone, this went on for a few minutes until my body gave out and i collapsed
grand torinos pov
grand torino: looks like he hit his limit
i landed next to him and called toshinori to come pick him up
all might: i am here! hello sir!
grand torino: toshinori its good to see you
all might: how are you sir?
grand torino: i'm okay, you seem well
all might: yes,hows y/n been doing?
he picked him up
grand torino: he already figured out how to let one for all flow, he even managed to match my speed
all might: already? he really is amazing
grand torino: Miku would be proud
all might: yeah she would, but she's watching over us
grand torino: yeah, well you better get him home so he can rest
all might: got it sir, have a good day
grand torino: you too
all might: thank you
i nodded at him taking one last look at y/n, he'll be a great hero some day
time skip
all might pov
i put y/n down on his bed and saw his body relax and a small smile tug at his lips, the sight made me feel happy
all might: goodnight y/n well done today
i walked out and heard the doorbell ring
all might: hello?
hizashi(mic): hey toshinori!
all might: mic keep it down
hizashi: sorry toshi
all might: what are you doing here anyway?
aizawa: he dragged us here
all might: aizawa old friend
nemuri(midnight): hey toshi
all might: hello nemuri
hizashi: soooooo.... you wanna hang out?
all might: i would but i just put y/n down to sleep
nemuri: aww~! i bet he looks so cute!
all might: please be quieter
nemuri: can i go see him?
all might: yes i suppose
she rushed upstairs to y/n's room, i let out a sigh
all might: you wanna come in, we can have a drink
aizawa: sure
hizashi: yeah bro
i led them to the kitchen and got them some drinks
aizawa: so how's y/n's training going?
all might: good, he's already put on some muscle and grown a bit,his quirk helps with that, and he's gotten around his limb damaging problem
aizawa: good, i bet he'll be a great hero in his life
all might:you might be his home room teacher
hizashi: i feel bad for him
i chuckled as aizawa wrapped up hizashi
all might: hold on, i gotta check on y/n, i'll be back in a minute
i walked upstairs and saw y/n cuddled into nemuri
nemuri: he's so cute~
all might: haha,well he seems comfy, when you come down we got drinks down stairs
nemuri: okay
i walked back down stairs and saw a picture of Miku and me hugging on a dock in front of a cruise ship
all might: thank you Miku, you gave us the greatest son ever, i promise i'll look over him and... i'll see you again someday, nighteye told me so
i put my hand on the picture and then walked down stairs as i saw aizawa restraining mic with his wraps
all might: good thing i have great friends too
