All For One: Rebirth in a New Era

---

**Year 2000**, a surprising year for many, marked the beginning of quirks. The story starts with a significant event in Qingqing City, China, where a baby was born emitting a radiant light—the first documented case of a quirk, or special power, in a human. This event signaled the dawn of a new era for humanity.

Six years have passed, and now it's **2006**. I, Isamu Shigaraki, am four years old. To some, I am known as All For One, and I am a reincarnated soul. Currently, I live with my brother, Yoichi Shigaraki, and my mother, Reiko Shigaraki, in a two-bedroom apartment with a bathroom, kitchen, and living room.

Reiko: "Kids, today we're going to the doctor to see if you have quirks or not."

We both nodded, and I continued writing about the events of *My Hero Academia*. Although I already knew I had a quirk since birth, I have never used it.

Yoichi: "Brother, what do you plan to do if your quirk awakens?"

Isamu: "Nothing."

Yoichi smiled and returned to his spot while I continued writing the story of *My Hero Academia*, occasionally wondering what would happen if I weren't in this situation.

Time passed, and our mother called out.

Reiko: "Kids, it's time to go to the doctor!"

We left our rooms, held her hand, and started walking to the clinic. As we descended the building, we saw several women prostitutes and men offering drugs or living on the streets. This was Kamagasaki, Japan's poorest district, with high crime rates and prostitution.

We walked several meters until we reached the hospital. Without waiting in line, a robust man with long hair greeted us. He spoke to my mother:

Doctor: "One of your children has a quirk, and the other does not. The one with a quirk is Isamu Shigaraki, and the one without is Yoichi Shigaraki."

Reiko: "Do you know what quirk my son has?"

Doctor: "No, ma'am."

Reiko: "Alright, thank you."

We left the office and returned home. Upon arriving, our mother said:

Reiko: "In 20 minutes, I'm going to work. I left food in the fridge and 200 yen for whatever you want at the store. I also left the house keys in the usual spot. Don't stay up late, and don't wait for me. Goodbye."

She quickly changed clothes, kissed us on the forehead, and left.

A few minutes later, Yoichi asked:

Yoichi: "Brother, can I go out to play?"

Isamu: "Yes, but tell me the rules for being on the street."

Yoichi happily responded:

Yoichi: "Don't talk to strangers, don't accept anything from anyone, and return home if the men outside start fighting."

Isamu: "Okay. I'm going to the store. What do you want?"

Yoichi: "A juice of any flavor, except kiwi."

Isamu: "Okay, see you, brother, take care."

I grabbed the money, and we left the house, taking different paths.

I walked for several minutes until I reached an alley where I started shouting:

Isamu: "Quirk removal for 100 yen!"

A lot of people, especially those with mutation quirks, gathered around me. A man with a baby whose head looked like a hammer approached me.

Man: "I want you to remove the quirk from my baby."

He handed me 100 yen, and I replied:

Isamu: "Give me your baby's hand, and you'll see."

The man gave me the baby's hand, and I closed my eyes, focusing my energy to extract the quirk. Gradually, the baby's head lost its hammer shape.

Then I heard bells ringing in my head. When I opened my eyes, I saw a golden screen.

The screen closed, and the people around me got excited. The man thanked me:

Man: "Thank you very much, kid."

Isamu: "No problem. Please form a line and have 100 yen ready."

Next was a woman with her child.

Woman: "I want you to remove the quirk from my child."

She handed me 100 yen. I took the baby's hand and repeated the process. The system sounded again, and I told the woman:

Isamu: "Done. Next."

I continued this for several hours until the sun began to set. I told the people:

Isamu: "That's it for today. I'll be back tomorrow, and you can bring your friends or family."

Everyone nodded and left. I also left and walked to a convenience store, where I bought two juices, one apple and the other mango. I returned to our apartment and saw my brother Yoichi watching TV.

Yoichi: "Brother, why did you take so long?"

Isamu: "I got a job."

Yoichi: "Wow!"

Isamu: "Let's eat."

I heated the food our mother left in the fridge, and we ate together. Afterward, I told Yoichi:

Isamu: "Yoichi, let's take a bath."

We undressed and I started bathing him. As I did, he asked:

Yoichi: "Brother, have you ever wondered what would happen if we had a dad?"

Isamu: "Yes, brother. Mom would work less. Why do you ask?"

Yoichi: "Today, everyone was talking about how amazing their dads were, and they asked me if I had one. I said no, and they started laughing."

Seeing tears in Yoichi's eyes, I said:

Isamu: "Don't cry, Yoichi. If they laugh at you, tell them you had a dad, and he's in the USA."

Yoichi nodded. I quickly finished bathing him, and then it was my turn. We got dressed, and I asked:

Isamu: "Yoichi, do you want anything for dinner?"

Yoichi: "No, brother, thanks."

Isamu: "Then let's go to bed."

Yoichi nodded, and we went to bed.

Yoichi: "Good night, brother."

Isamu: "Good night, brother. I love you."

Yoichi closed his eyes and fell asleep. Then I said:

Isamu: "System."

The same system screen appeared.

The last abilities surprised me. Before I could do anything else with the system, a screen appeared, saying:

(System update)

Yes/No?

I tapped "Yes" in the air. All the windows closed, and only the following text appeared:

The screen closed, and I turned to see my brother already asleep. Then I slowly closed my eyes and drifted off to sleep.
