Side Character Transmigrations: The Final Boss is No Joke - Chapter 1

Five years ago, humanity’s strongest Tower Climber was betrayed at the peak of his conquest.Rael Arden, known only by his codename Phantom, was the silent genius who cleared impossible floors, crushed monsters with forbidden magic, and shaped the rules of Tower exploration. No one had ever seen his real face—yet his legend was feared across the world.But at the Tower’s summit, the teammates he carried to glory stabbed him in the back. For power. For godhood. For fear of what he might become.They thought he died.They were wrong.Reincarnated in secret, Rael awakens in a modern world that’s on the edge of collapse. Dungeons bleed into cities. Monsters evolve. The Tower is no longer just a gate—it’s infecting the world. And the very ones who betrayed him now rule from the shadows, hiding behind titles, guilds, and lies.But Rael isn’t alone. His soul split across hidden clone bodies, each designed to infiltrate, gather information, and prepare for war. As each clone reawakens, his power grows—and so does his rage.With him are three women tied to his fate:Selene, the shadow rogue who never betrayed him.Lyra, a curious researcher drawn to the legend of the Phantom.Aeris, the sword saint who still mourns his death… and may not be as loyal to the enemy as she seems.Now, Rael hunts the seven betrayers who destroyed his past.One by one, they will fall.But revenge is just the beginning.Because deep within the Tower, something else is waking—an ancient force that even Rael feared. And this time, the world may not survive unless the Phantom reigns again.

Nagasawa crossed to Naruto Universe and was bound to Konohagakure.If Konoha is severely damaged and destroyed, Nagasawa’s lifespan will be reduced.He panicked at the thought of the upcoming Nine-Tailed Demon Fox's attack , and the thought of Konoha getting destroyed left him in despair.Fortunately, while bound to Konoha, he can obtain templates of powerful characters.At the beginning, He got the Whitebeard template! Since it's the Whitebeard from the Summit War of Marineford, he can use Tremor-Tremor Fruit's ability and Haki.Facing the Tailed Beast Ball, which terrorized Konoha Shinobi, Nagasawa leaped and shattered the Tailed Beast Ball with one punch!

Lu Liran, the former deputy captain of the first federal mobile team, disappeared in a great war, and his life and death are unknown.
Seriously injured in the war, lingering on his last breath and penniless, Lu Liran was luckily bound by the survival system.
Under the tasks issued by the system——

The Giant at thirty degrees below zero, conquer the Arlok Glacier;
In the No Man’s land under the black wind and sand, travel deep into the oasis in the hinterland of Salba Desert;
The Island in the Sky under the blue sky, the challenge of surviving on an uninhabited island;
The Blue Hole in the Endless Abyss, exploring deep sea wrecks and lost ancient cities.
The Muddy Lands, the Forest of White Bones, gathering specialties of the Haunted Swamp;
The Lord of Fire, the giant dragon lurking on the ground……

Therefore, in the Desolate Star that hates the federal army the most, a man with a disfigured face and mysterious identity quietly appeared in the top ten dangerous uninhabited regions of Desolate Star. In exchange for rich bounty rewards by hunting rare and exotic beasts that ordinary people can’t hunt, and the live broadcast of wilderness survival, he also started rapidly sweeping the entire planet.

“Ah, the anchor looks so scary, no one dares to marry such an Alpha no matter how powerful he is!”

“??? Brother Lu, I can! Marry me! The sense of security is at max level, like!”

“The anchor is really a god. This is the first time I’ve seen someone at the top of this year’s list of Desolate Star’s Most Attractive Alpha + Least Wanted to Marry Alpha at the same time…”

During a live broadcast, a heavy rain washed away the scar on Lu Liran’s face.

The whole live room is boiling!!!

“Marry me, marry me! Brother, marry me!”

After the live broadcast was closed, another man, so handsome that people subconsciously held their breath, appeared. He surrounded Lu Liran’s body and whispered: “You’ve been missing for so many years with my cub, when are you going to give me a name?”

Lu Liran: “…”

Yes, this is still an old-fashioned story of O pretending to be A and running away with joy.

…

His Excellency, the First Commander of the Federal Army, disappeared suddenly in the peaceful post-war era. Until one day, everyone noticed that he appeared in a live broadcast room, happily pretending to be a s*upid human-shaped pendant, and unscrupulously pestering a male anchor with a terrifying face.

“Official announcement, this is the commander’s wife.” His Excellency, the Commander-in-Chief of the Federation, said so.

The live broadcast room is boiling again!!!
