Fist of the North Star manga volume 17 features story by Buronson and art by Tetsuo Hara.

Kenshiro and Ryu have reached the land of Sava, a kingdom nestled in a mountain valley. But Sava is under attack from barbarians, and even worse, its royal family is weakened by internal strife. King Asam is ill and dying, and his three sons now squabble for the throne. Kenshiro might be able to knock some sense into the competing brothers, but he'd better do it quickly. Something strange has happened in the neighboring kingdom of Blanca, and Sava has more to worry about than just the barbarians!
