Blackout.
In Seoul, strength decides everything.
Schools are ruled by fighters. Crews control the streets. Money buys power, and the weak are crushed quietly beneath it all.
Han Siheon is nobody.
An orphan surviving through part-time jobs, sleepless nights, and silence, he lives unnoticed at the edge of the city. No friends. No dreams. No future.
Until one night, he witnesses something he was never supposed to see.
A student disappears after crossing paths with a hidden organization known only as BLACKOUT.
No police report.
No investigation.
No trace left behind.
As Siheon digs deeper, he’s pulled into the violent underground world connected to J High, runaway crews, illegal fight rings, and Seoul’s darkest businesses. Along the way, he crosses paths with monsters disguised as students and legends whispered about across Korea.
But BLACKOUT is different from ordinary gangs.
They don’t just ruin lives.
They erase them.
Now trapped between the Four Major Crews, underground politics, and a secret organization hiding beneath Seoul itself, Han Siheon must fight to survive in a world where losing once can make you disappear forever.
this is the story that unfolds in the shadows.
