Breaker Omnibus GN Vol 04 (MR)

Chun-Woo Han, aka Goo Moon Ryong, aka Nine-Door Dragon, must rescue his student Si-Woon from the martial arts alliance, and the only way to do so is to put his own life on the line! Taking a page from the book of his own master, Chun-Woo starts down a dangerous path for his disciple's sake.
Hoping to finally bring an end to his long-lasting misfortunes, the Goo Moon Ryong willingly jumps into a trap, leading to what could be his final battle against the skilled fighters of the alliance. And while the big clash between the showy techniques of the martial arts schools and the immovable will of the Nine-Door Dragon will make alliance fighters fall like autumn leaves, Chun-Woo may not have what it takes to get past the most elite fighters of the Murim worlds and save Si-Woon!
