Leon had always been the weakest.
In school, in sports, and in his entire life, nothing about him ever stood out. While others were strong, confident, and talented, Leon was just… ordinary. No strength. No skills. No special talent.
But tonight was different.
As Leon walked home late at night, he felt the ground tremble beneath his feet. The city lights flickered. A cold wind brushed past him. Something unseen was calling him toward an abandoned construction site.
A deep heartbeat echoed around him.
Not his own.
The ground cracked open, and a sharp beam of blue light shot upward. Lines of glowing energy spread across the earth—branching like veins under the skin of the world.
Leon stepped back, fear rising in his chest.
But before he could escape, the blue light rushed toward him and wrapped around his body like living energy. The shockwave slammed him to the ground. His vision blurred, and his heartbeat raced uncontrollably.
Then a glowing blue screen appeared in midair.

Leon stared at it, stunned.
"What… what is happening?"
Another line appeared:
The Infinite Vein has chosen you.
A new path begins.
Suddenly a sharp pain shot through his chest. It felt like invisible hands were carving new pathways inside his body—opening something that had been asleep for his entire life. His veins burned. His muscles tightened. His fingers tingled with power.
Leon screamed.
Then everything went silent.
When he stood up, blue sparks flickered around his body. He felt lighter, stronger, and faster—like the world had slowed down around him.
Another message appeared:
Tutorial Quest Unlocked:
Defeat the creature watching you.
Reward: +1 Level
Leon froze.
Watching me?
He turned slowly.
Behind a broken wall, two glowing red eyes were staring at him.
Not human.
Not friendly.
Not from this world.
Leon swallowed hard.
His fist trembled.
His new life had just begun.
