Harsh Reality but Strong Optimism.

'Where am I, *grumble* can't see, have I already reincarnated?' Kai thought to himself while trying to move.

Suddenly, Kai was lifted by someone.

"Hello Kai I'm mommy" said the mysterious woman while carrying Kai.

´Mommy is she my mom in this world? Well, ok I'll keep pretending to be a normal baby for now' Kai thought while trying to move.

"Oh, dear it seems like he has allot of energy" the woman said to the male figure in front of her.

"Humph let's just hope he is not a failure, the only reason why he was born was for the benefit of the company so he better not be a blank". Said the male figure with an annoyed tone.

'Welp, crap how do I tell him that I don't have a quirk? Wait, wait a second Kai, maybe he is a tsundere, like the grandfather of Kusuo Saiki. Yes, let's hope for that' thought Kai trying to convince himself about the harsh truth his possible father will have to face in the future.

"So have you decided he's name yet" asked the woman to the man.

"I couldn't care less, name him however you want" the man said while exiting the room.

While looking helplessly at the door the woman lifted her chin and looked at Kai, after seeing he's face, she asked him "so son would you like the name of Kaito?".

After hearing the name Kai immediately laughed to show how much he liked it.

After seeing this the woman smiled and said while hugging Kaito "my name is Kobayashi Kaia, your father doesn't want you to have he's last name yet so for now you are Kobayashi Kaito, are you happy with this?".

Kaito was stunned, he wondered why he's mother would say such a thing, but for now he only smiled and gave her a somewhat of a kiss, needless to say that Kaia was extremely happy.

[Kaito POV]

It has been 2 years since my reincarnation, the first thing I noticed was that my father was basically never in the house and my mom was the only one who would stay with me, the house where we live is big too big in fact, it reminds me of Yaororozu's home. Even when we had maids my mother was the one that would remain with me almost 24/7, to be honest I was a bit sad when I thought of letting everyone's expectations down when they discover the fact that I'm quirkless, but I'm not the type of person to regret he's own actions so I'll cross that bridge when I get there.

In these 2 years I managed to find who my father is, he's name is Masaru Daisuke, apparently, he is co-founder descendant of the hero association, I know I was also tripping balls when I heard this. If I had to say the most interesting thing I have done it would be the fact that I do nothing but read and do breathing exercises, even though I have the Kimetsu no Yaiba manual the truth of the matter is that my body is too weak to even handle Zen Shūchū no kokyū so I can only practice a lesser version and can only do it at least 1 hour per day, of course this means that I also have not done even the single physical exercise the best I can do is "run" around the house, sliding, jumping and dodging, I'd say it is good enough for now let's hope nothing goes wrong.

Today is the day I'm getting tested for quirks, even though I know the answer it is still nerve cracking.

(After the tests)

I was sitting in the bed of the room and my parents were beside me, I noticed my mom's worried expression while my father had an impatient one.

A few seconds later the doctor came in and said in a low and somewhat sad tone "Miss Kobayashi Mr. Masaru, I have the sad news that your child Kobayashi Kaito is quirkless".

After hearing this my mother's face went pale and my fathers was red as if he was boiling with anger.

My mother tried to calm my dad saying "d-d-dear its not s-s-o bad" my mom was scared, suddenly my father slapped her, I was in shock and almost immediately I also received a slap.

Furious my father said "get your things out of my house and never come back, I don't need a useless wife and a reject of a son".

I rushed at mom to try and help her but she was helplessly crying, afterwards I got angry and shouted "WHY DID YOU HIT MOM WHAT DID SHE DID TO YOU!!!!!" I have never been so angry in my whole life even in my past life the worst was a tantrum for ice-cream.

My father got closer to me and kicked me, I lost all the air in my lungs but I felt that nothing was wrong but it still hurt, afterwards my father with he's cold voice said "how dare a reject like you to talk back to me, but since you are going to disappear from my life, I don't mind telling you if you can even understand it. Your mother and I are or rather were on a fixed marriage, it is an activity in which to persons with powerful quirks join themselves in matrimony with the hope of creating a child with an enhanced or combined version of each of the parent's quirks, however since you are quirkless I don't need a son like you"

Father's words hit me like a truck I couldn't believe what he was saying, before I could think straight, I asked again "but why, why do this from the beginning?"

My father subsided he's anger and answered "to create the best hero of course, since the creation of the hero system every politician has tried to take over the top 10 heroes for their political and economical faces to advance towards the rest, however after All Might became Japan's No1 hero no one has been able to reach to him since he always avoid them, so I thought if I create the next No1 hero everything will be under my control, my quirk is known as Darkness is a quirk that allows me to merge myself in dark areas, but also allows me to create weapons and elements from said darkness, your mother has the quirk of spatial space she can create a pocket dimension in which she can store anything up to a certain limit, but now my dreams are shattered because of your uselessness, I believe I have wasted more time than I should so I'll be leaving, goodbye Kaito let our paths to never cross again".

With that my father left the room, there was a moment of silence before my mom said to me "I'm sorry, I'm sorry for being such a lousy mother that cannot even give you a proper quirk" after hearing this my mother burst into tears, so I hugged her.

She was shocked but before she could say anything I told her "Mom you don't have to apologize for anything, I don't have a quirk but I have a strong and healthy body, I love you for that and even if I could get the same quirk as All Might I would not change anything for this body that you gave me".

My mother and I remained there crying for who knows how much time until some men escorted us out of the doctor's office.

My mom was forced to sign a warrant in which she was not allowed to talk about my father, my father did not include me in the warrant because he thought I was a dumb child so he left me out of it "ha sucker" I thought, after signing the papers my mother and I were at the front of the hospital with a few bags and 100,000¥.

My mother sighed as if a weight was lifted upon her and said "Kaito, beyond this point forward we are going to be on a rough road for a long time so again sorry for not being a good and competent mother, I can leave you in an orphanage, they will take care of you or you can come with me…" before she could finish, I immediately answered "with you with you I don't need anything else I'll be with you forever".

My mother was about to cry, she cleaned the tears in her eyes and said "ok honey lets see what the future has for us, do you know what you want to be?"

I answered yelling "I WILL BECOME A TOP 10 HERO; I'LL SHOW THAT NO MATTER WHO YOU ARE OR HOW WHERE YOU BORN EVERYONE CAN BECOME WHAT THEY WISH FOR!!!!!!!!!!!!"

My mother was shocked and the told me "If that's what you wish then mommy will help you in any way she can".

I smiled and went forward with my mother in search for our new home.
