Rebirth of the Strongest Dungeon Master

The Ryudo Family was a small Yakuza family headquartered in Shibuya, Tokyo.

Starting from thirty members, including the founder, Haruno Ryu, they collected a lot of money from illegal activities; gambling, narcotics, extortion to murder, and many more.

The Ryudo Family was relatively weak in the underworld. They couldn't compete with other syndicates. For 20 years, since the organization was formed, there had been no significant development at all. Even so, their brotherly bond remained strong.

However, everything started to change since the Dungeon landed on Earth. All members of the Ryudo Family experienced an awakening.

At that time, Japan was in turmoil, just like any other country. Violent monsters that only existed in fantasy stories appeared in the real world and preyed on humans. It was a national disaster.

While people viewed this as a disaster, there was one person who saw this situation as a golden opportunity. It was Akira Takaoka, Vice Chairman of the Ryudo Family.

"Every disaster has an opportunity."

Akira advised Haruno Ryu to recruit people who had experienced awakening, especially those people with criminal records. When the government focused on dealing with disaster, the Ryudo Family expanded its power. They got rid of all their rivals in the same area.

Within 5 months, they took control of Shibuya and Shinjuku. They even managed to make Kabukicho the business centre of the dark world.

Thus, the Ryudo Family became the most powerful syndicate in Tokyo.

However, the power achieved by the Ryudo Family brought corruption.

It turned out that without Haruno Ryu's knowledge, Akira built strength. He gathered strong and loyal people, then disarmed all of Haruno Ryu's confidants. In the family meeting, he forced Haruno Ryu to step down from his position, but the man refused. As a result, Haruno Ryu was killed on the spot.

That way, the Ryudo Family fell into the hands of Akira Takaoka completely.

Haruno Ryu not only left the Ryudo Family, but also a descendant who has been prepared to become the heir—Haruno Taji.

He was the 'old friend' that Isaac was looking for.

"After all I gave, this is what I got?"

Taji had devoted his time, energy, and even morals to the Ryudo Family. He had been involved in many criminal acts. He was even willing to get his hands dirty with blood by becoming a hitman for the Ryudo Family.

None of his targets ever managed to escape alive.

He studied the systema at the highest level and even mastered various weapons; everything he did was to complete every task given by the Ryudo Family.

After his selfless devotion, those he trusted the most paid him back with betrayal and his father's death.

Hence, Taji tried to claim his right. If he couldn't get his right back, then he would just destroy it.

And he did it right now.

In the midst of heavy rain, Taji slaughtered the Ryudo Family members witnessed by dozens of pairs of eyes, though they were only a small part of this big syndicate.

"Come on… let's forget about that problem."

There was only one person standing in fear. The man repeatedly persuaded Taji to join the Ryudo Family, but his words were ignored.

Taji continued to walk while aiming his dagger at the man's neck.

"Traitor must die."

Splat—!

The man's neck was bleeding, and he suddenly collapsed.

The last man had died.

With this, the bloodshed ended. At least for the first wave.

"OOOOYY!"

A loud cry echoed amidst the sound of the pouring rain. Taji's attention immediately shifted to the voice.

A group of fierce-looking men came with weapons. They appeared from two directions, blocking all the escape routes. If Taji counted, their numbers reached 100 people.

They were members of the Ryudo Family. All of them were E-Class Hunters with a level above 10.

The actual bloodbath was about to begin.

A man with dyed blond hair stepped forward. He looked around. His comrades were lying lifelessly on the asphalt.

The blonde-haired man spat out. "So, you're the one who's been interfering with our business?"

"Yes," Taji replied firmly.

The man with polished hair was furious. "Kill that bastard!"

Instantly, a sea of people attacked Tanji who fought alone. The Oni masked man swayed because dozens of humans attacked him in turn.

Splat! Splat!

"Arrrg!"

Various sharp weapons; axes, swords, spears, katana, came close to his neck. Some of the weapons managed to graze on his skin.

However, what happened was the opposite. Tanji slaughtered them all. Not the other way around.

Splat! Splat! Splat!

Everyone who tried to approach Taji was killed. The dagger in his hand was incessantly stabbing at the human stomach and chest.

"Don't let him escape! Attack!"

Taji quickly jumped high and floated in the air for a split second to find a position, but the enemy did not stand still. Instantly, bolts of flames and ice crystals aimed out of his life.

Clang! Clang!

Taji managed to block off the ice crystals, but he couldn't dodge the flames. Part of his arm was burned.

He landed on the body of one of the enemies and slit the man's throat.

Splat!

After that, dozens of people immediately attacked Taji in various directions. Some of the attacks were deflected, and they hurt each other. However, many attacks also landed on Taji's body.

"Arrrgh! Run forward, all of you!"

Stab! Stab! Splat—!

Three people died covered in blood. Their bodies were trampled.

Slash! Slash! Splat!

Five people died. Two of them had their necks nearly cut off.

"Arrrrrgh!"

The one-on-a hundred battle continued. As time went by, the battle got fiercer.

The rain grew heavier, sweeping red blood into the gutter. Screams echoed along with the sound of trickling water.

Taji continued to fend off the onslaught of dozens of humans. His body continued to move, even though his muscles screamed in pain.

Splat! Splat! Splat!

He kept fighting, regardless of his condition.

"Keugh—"

As time went on, his body became heavier and heavier. His movements slowed, and he started to feel pain every time he moved.

"Hiyah!"

Bang! Bang! Slash!

Suddenly, his body stopped moving, then various attacks hit him.

"Arrrgh!"

When Taji saw himself, his entire body was covered in blood and full of cuts. The mask was half shattered, showing part of his face.

"Looks like I've reached my limit…"

After that, Taji collapsed. His body was lying in a pool of rain and blood. He realized he had lost. At that moment, Taji had accepted his fate.

However, strangely, his opponents kept their distance. This surprised Taji.

Then, he saw the figure of a man standing before his face. The man looked like he was a foreigner; white hair while holding guns.

"Who are you?"

Taji's voice was weak, but the man still could hear him.

"Nobody. Just someone who wants to return the favour."

Taji closed his eyes. After that, all he heard was the sound of non-stop gunfire.
