The Case Where I, The Strongest Mercenary, was Reincarnated as a Bullied, Introverted High School Student – With My Unbeatable Fighting Skills, I Rule the School and Underworld

Bang Bang Bang!

The sound of guns of the mafia rang out loudly.

Deep in the forest that had become such a battlefield, I―Ryuji Miyamoto―was fighting tirelessly all by myself.

“It’s The Invincible Dragon’! “Kill him!” 

“If you kill him, you’ll be promoted to executive rank at once! “

“He’s the only one left! “We still have 40 soldiers here!” 

The ‘Invincible Dragon’ is a nickname given to me by my enemies, who fear me.

There is also a huge bounty on my head.

As a mercenary, I was aiming for a base deep in this forest.

My objective is to destroy a certain weapon.

Intercontinental Stealth Ballistic Missile (IICBM).

It’s a new type of sonic missile with stealth capabilities added to conventional missiles.

The Mafia’s goal is to launch it at Tokyo, the Japanese capital.

The base just ahead was the launch pad.

Nowadays, a single missile is enough to start a war.

Japan’s missile interceptor technology is not as advanced as that of the U.S. If a missile lands on Japan, the U.S. will side with Japan, and a world war involving the entire world will begin in a matter of seconds.

So, I must destroy the missile along with its base to prevent a world war.

My comrades have sacrificed their lives, and I, entrusted with their final wish, have been given a mission that I must accomplish.

“Phew…”

With a deep breath to sharpen my mind, I began my counterattack.

With a survival knife in hand, I crawl through the forest like a snake, silently killing each of the mafia members one by one.

Stealing the enemy’s weapons, hiding, making them fight each other, strangling them, and cutting off their heads―and then I’m gone.

Gunfights, hand-to-hand combat, stealth, diversion… I used every skill at my disposal as a mercenary to turn the overwhelmingly disadvantageous situation in my favor.

“No. He’s too strong! It’s no use!”

“He’s moving too fast! I can’t get a shot off!”

“The voices of my allies are disappearing one after another… Damn it! Where are you?”

The high-spirited mafia voices turned into screams for help.

Even so, I continue to kill mafia members to avenge the deaths of my comrades.

I remained active and relentless until the forest returned to its natural silence.

After defeating the enemies, I arrived at the launch pad for the Intercontinental Stealth Ballistic Missile (IICBM).

“If I destroy this, the mafia’s plot would fail.”

The timer was already running, and I had to quickly destroy the missile along with the base.

With a heavy heart, I took out a photo of my family that I had kept in my chest pocket and gazed at it one last time.

I’m rendezvous to hell with this missile.

“Shiori, Yuuka, Masaya… Please be happy.”

BOOM!

The surrounding air trembles in the aftermath of the base’s explosion.

On that day, without anyone knowing, the legendary mercenary saved the world and departed from this world.

The invincible dragon ascended to heaven as a heroic spirit.

―However, it seems that there was no place for him in heaven or hell.

As if drawn by something, Ryuji Miyamoto’s soul took up residence in the body of a certain dull, bullied high school boy in Japan.
