Castle 2: Maninjisang

Shin Kim is an elite assassin driven by a singular, consuming purpose: the total destruction of Castle, the undisputed absolute power ruling the criminal underworld. To achieve this monumental goal, he recruits and unites skilled fighters from across the country, forging them into a formidable organization known as Baek-Yi. With his forces assembled, Shin prepares to wage war against the very syndicate that dominates the shadows. However, rather than launching a direct assault, Shin orchestrates a calculated infiltration. Through a tense negotiation, he secures a position within Castle itself, forcing him to work side by side with the very enemies he swore to annihilate. Now embedded deep within the heart of the underworld's most powerful faction, he must navigate a treacherous environment where a single misstep could mean death. As he walks the razor's edge between ally and saboteur, one question remains: will Shin successfully dismantle Castle from the inside and finally claim his long-sought revenge?
