Chapter 1: Royalty of Tokyo

In the underground, one villain controls all. His name, All for One. But it wasn't the same always. Before, the yakuza, ruled everything. And when I say everything, I mean, everything.

From bath houses to sports, he had all and everyone in his pocket. Hell, even when quirks arrived, they still had a good control over the game.

Then the heroes and villain system appeared. Then, it went to shit.

The yakuza might be ruthless and criminals, but the live with honor. They would never lower themselves to the thugs that use quirks however they see fit, they would never be villains, no matter what people said.

But raid after raid, arrest after arrest... they lost. With heroes like All Might and Endeavor, made things hard. And it was even harder when you fought two wars at the same time.

If the heroes stopped them, All for One destroyed them. You either joined him, or you can say goodbye to your quirk and life.

The Boss, a respected crime lord of a past era, knew that fighting this, would end in more bloodshed.

Over the years, The Boss became the one leader of every Yakuza family, everyone respects him and fears him. So, when he speaks, people listen.

And people obey.

Just like that, the Yakuza, once the most feared mobs in all the planet, became another bunch of villains.

Their operations were taken by All for One, their weapons confiscated by heroes, and they are under surveillance 24/7.

Izuku remembers when his grandpa called him the day after they fell. He was in his office, drinking sake as he looked across the window. His father and mother died early in his life, so this old man, was the one raising him.

"Little Izuku, I want you to promise me something." He started as Izuku sat in front of him "You will bring glory to our family again, but you will never lower to the standards of villains."

Izuku tilted his head "How so?"

The Boss smiled and ruffled his green hair "You know what makes us different from the rats?"

"Ehm..."

"The Jingi. Our code of ethics. You will live and die with them. That way, you will not be another villain. You will not be All for One..."

"You will be the new king of this country."

Izuku knows the Jingi from memory. There aren't that many rules, but that he will never break. He knows that the Yakuza are criminals, but they are different. Their Ninkyodo (Chivalry) should put them up over the random thug.

A lot of shit had happened since that day. Her cousin, Eri killed his uncle and now he takes care of her, God bless her. More than cousins, she is her sister.

The rivalry between Chisaki and himself. Both of them want to bring the Yakuza to glory again, and both are the candidates of the Old Man to rule the new generation as he called it. He respects Chisaki and Chisaki respects him. But neither likes each other. Mainly for their methods.

Chisaki has taken his branch of the Yakuza that he took control after the hospitalization of the Old Man, the Shie Hassaikai, and has become a violent group. He hates the word, but is the only word he has for them, boryokudan (Violent Group), how the cops and civilians see the yakuza.

His own branch, the Juunishi (12 Signs of the Zodiac) has been respecting the Ninkyodo since its formation and lives by the Jingi. And if you are wondering, the Jingi is the following.

Respect your Oyabun (Father) in this case the old man.

Don't steal from the everyday man.

Don't disrupt the harmony of the gang, be Shie Hassaikai or the Juunishi.

Never involves yourself with drugs. Be selling them or consuming them.

Always act chivalrously.

And now, the Juunishi are having a meeting, to discuss their next move.

The first to take over.

*Club Sunshine*

In the VIP section of the club, there is a round table, with twelve sits on it. In each sit, there is someone sat. All dressed in sharp suits, where tattoos covered their bodies.

"Well, we are all here at time, so we can begin I imagine." Monoma Neito, 12th son of the Zodiac, sign of Saru (Monkey). Quirk being Copy; can duplicate someone's quirk by making physical contact with that person.

"Hell yeah! I can't wait to make big moves now!" Tetsutetsu Tetsutetsu, 11th son of the Zodiac, sign of Tori (Rooster). Quirk being Steel; can turn his body into iron. The strength of his quirk depends on his ingestion of iron.

"I agree! We need to show our hot spirits and passion we have! Otherwise, we will get stomped!" Inasa Yoarashi, 10th son of the Zodiac, sign of the Hitsuji (Sheep). Quirk being Whirlwind; He can manipulate freely the air around him over a wide area.

"You are too loud. Each and every one of you." Shinso Hitoshi, 9th son of the Zodiac, sign of the Nezumi (Rat). Quirk being Brainwash; When his target answers him verbally, it is put under his control.

"I saw that light is breaking into the darkness our group has been trapped. Something will change soon?" Fumikage Tokoyami, 8th son of the Zodiac, sign of Hebi (Snake). Quirk being Dark Shadow; he can create a sentient monster of shadow that can communicate and move freely.

"I don't know what you mean, but it sounds positive!" Tenya Iilda, 7th son of the Zodiac, sign of the Uma (Horse). Quirk being Engine; his calves have car-like engines giving him an incredible running speed and kicking power. The engine gets fueled with orange juice.

"...I... Sure..." Tamaki Amajiki, 6th son of the Zodiac, sign of the Usagi (Rabbit). Quirk being Manifest; he can manifest physical characteristics of any animal he eaten.

"That's the spirit! Now, let's start the meeting!" Mirio Togata, 5th son of the Zodiac, sign of Inu (Dog). Quirk being Permeation; He can become intangible and pass across any tangible matter.

"You know, we have to wait for the food first. Our rules dude." Ejiro Kirishima, 4th son of the Zodiac, sign of the Ushi (Ox). Quirk being Hardening; he can harden and sharpen any part of his body.

"..." Shoto Todoroki, 3rd son of the Zodiac, sign of Inoshishi (Boar). Quirk being Half-Cold Half-Hot; He can generate ice from his right side and flames from his left side.

"Shut the fuck up! Tatsu will say when the meeting starts and when it finishes!" Katsuki Bakugo, 2nd son of the Zodiac, sign of Tora (Tiger). Quirk being Explosion; his sweat in his palms is nitroglycerin-like and he can ignite it on command to create explosions.

Everyone turned to Tatsu, that looked at the door open as the waitress bought the food. He waited for them to leave and once they closed the door he smiled "Now, we can begin. First off, enjoy the food." Izuku Yamaguchi, 1st son of the Zodiac, sign of Tatsu (Dragon). Quirk being Ultra Processing; His body works faster than the regular human, making wounds heal almost instantly, even those that could kill at impact, and his brain can process more things at a higher speed.

As they started to eat Izuku spoke "As you know; our cousin branch, the Shie Hassaikai, has been doing more and more criminal activities that break our code. Normally, The Boss would take care of it, but, my dear rival, Chisaki, is using the fact that he is in a coma to do whatever he wants without any repercussion. So; I believe it is time for us to start making more moves in the underworld. Ideas, comments?"

"Why don't we just go and beat their ass!?" Tetsu suggested and Monoma shook his head.

"Because it isn't the right time to do it. If we just go, bust down the door and start fighting, we, would be the bad guys in the situation by breaking the Jingi."

"But they already broke it! They committing petty crimes should give us the reason!" Inasa commented and Shoto nodded.

"In theory. But in reality, he has more influence than us in the family, due that most, if not all, fear him."

"And even if they respect Tatsu more, they don't believe he can beat Chisaki." Shinso said.

"The rumors also say that he is creating weapons to neutralize quirks." Tokoyami said rubbing his chin.

"They are. But the process is almost nonexistent..." Tamaki muttered.

"So, let's not worry 'bout that just yet. Back to the topic, how can we make them, the bad guys in the eyes of the Yakuza?" Kirishima continued the flow of the conversation.

"I know! We let them continue!" Mirio suggested and they looked at him.

"Why?" Tenya asked and Izuku smiled.

"That's good actually. The more they lower themselves, the less respect they will have in the family. The less respect... the more we gain." Izuku said "Very well, I want to have ears and eyes in the Shie Hassakai activates. If they kill to rob, I want to know, if they rape, I want to know, if they don't help a granny cross the street, I want to know. Tora, convince one of the lower thugs of the Shie Hassakai to help our cause."

Katsuki raised a brow "And if they refuse?"

Izuku smiled at him "I said convince. Not ask."

Katsuki smirked "It will be done. Anything else?"

"Yeah, Aoyama says that a new group of villains wants to meet me. They call themselves the League of Villains. Information on them?" Silence "Okay, the meeting will take place this Sunday at a bar. We have one week to find info on them. Inu, Uma and Nezumi; lift every single rock to find information on them. They might be small now, but I have a feeling about them. With that said..."

"Let's continue eating."

A/N: Okay, some things to clarify, because I did a lot of research on many things to make this.

The order (1st 2nd etc) is the order when they joined.

In the future I will do chapters on how each member joined.

The signs, they are from the Japanese Zodiac, I tried to fit each one on their personalities, not their birth.

Jingi, it exists. The code of honor and ethics of the Yakuza.

Yamaguchi, it exists, being called Yamaguchi-gumi. The biggest Yakuza family since 1915 😊.

I feel I forget something, so I'll answer questions and suggestions. Hate will be ignored.

Next Chapter: Life of a Yakuza Outside of it.
