The moment he opened his eyes, the disorienting rush of memories hit him. He wasn't in his old world anymore. This was different—dangerous. Growing up in Tokyo's tumultuous streets alongside a boy named Mikey, he found purpose in the chaos. But when betrayal struck and he was kidnapped to South Korea, the chains of survival hardened him.

Now at 17, free from his captors, he's determined to reclaim his life. Offering kindness to a stranger, Nam-Soon, he finds himself pulled back into the whirlwind of gang wars, underground martial arts, and a world where every choice could mean life or death. Unknown to everyone, his alibis and talents conceal a power that could shift the balance of the streets and the underground forever.
