Inheritance and Hierarchy: Isuma's Beginning in the Yakuza

The next morning, I felt something poking at my stomach. When I opened my eyes, I saw two things: first, I was lying on the couch, and second, the person poking me was Yoichi.

He looked at me with a smile and said:

—See you later, brother.

I raised my thumb in approval, and the last thing I heard was the door opening and closing as he left.

I stayed staring at the ceiling for a while until the clock struck 9:00 AM. As I stood up, a system screen appeared in front of me, displaying the following information:

- **Shop:** Purchase items, quirks, or upgrades using money or soul fragments.

Interesting, though a bit long. I moved my hand in the air and pressed the shop icon. Immediately, numerous pop-up windows appeared with messages like:

"Give me 100 quirks and you'll get 5 spins on the wheel."

"3 spins for 10 quirks."

"Buy an amulet and get 5 free spins."

I realized everything seemed to be about selling me something. It was like a flood of colorful ads surrounding me, until a small 2D gray monkey appeared, humming a tune.

The monkey turned to me and, with a smile, said:

—Hello, user. I'm your guide for the shop. Before you ask, no, I'm not an AI. I only answer simple questions.

I scratched my chin, curious, and asked:

—What are those pop-up windows?

The monkey also scratched its chin and replied:

—Those are offers from sellers. It's up to you whether to waste or use your stuff wisely.

I nodded, understanding that these were ads. The monkey continued:

—The shop is divided into three sections:

1. The first section is for products you can buy with money, like food, clothes, appliances, etc.

2. The second section is where you can acquire quirks from other "universes," using soul fragments.

3. The third section won't be available until the next update.

—Any questions? —the monkey finished.

Before I could answer, I heard a knock at the door.

*Knock! Knock! Knock!*

I got up from the couch, opened the door, and found a man in a brown suit holding a cardboard box.

—Hello, I'm here on behalf of Mr. Jiro. This package is for Isuma Shigaraki —he said.

—Yes, that's me —I replied.

The man lowered the box to the floor and handed me a pen.

—Please sign here before receiving your package.

I signed on the sheet he handed me, and the man added:

—Thank you. Here's your... relative. The pen is a gift.

He handed me the box and left. I brought the box inside, placed it on the dining table, and opened it. The seconds felt like they dragged on. When I finally opened it, I found an urn containing my mother's ashes.

I stared at the urn in silence for several minutes, processing the situation, until I heard knocking at the door again.

*Knock! Knock! Knock!*

I opened the door again, and this time it was Jiro, dressed in an elegant black suit and matching shoes. He was holding a box in his hands. Upon seeing him, I asked:

—Why did you come, Jiro?

—I want to talk to you, kid —he responded seriously.

I invited him in, and after closing the door, he looked at me and said:

—Before we talk, I brought you your new clothes.

He handed me the box, and I nodded gratefully.

—Thanks, Jiro.

We sat down at the dining table, and after a long silence, he began:

—Let me explain how the hierarchy works in our organization. We Yakuza follow a strict structure:

1. **Oyabun or Kumicho:** The supreme leader, the "father" of the organization.

2. **Wakagashira:** The second-in-command, the "older brother," who coordinates daily activities.

3. **Shateigashira:** The third in the hierarchy, in charge of regional operations.

4. **Kyodai:** The "older brothers," veterans with a certain level of power and responsibility.

5. **Shatei:** The "younger brothers," who report to the Kyodai.

6. **Kobun:** The newest or lowest-ranking members, apprentices.

—And what does this have to do with me? —I asked, a bit confused.

—Since you're now part of us, I'm assigning you the rank of Shatei, or "younger brother." I am Wakagashira, your "older brother" —Jiro explained.

I nodded, understanding.

—Now, put on your suit —Jiro instructed.

I took the box and went to my room. Inside, I found a suit consisting of a white long-sleeved shirt, an elegant black jacket, matching pants, and black shoes, all tailored to my size.

After changing, I returned to the dining room. Jiro looked at me, nodded, and said:

—You look good. Let's go.

He approached me, and a black liquid covered both of us.
