About the Fist of the North Star Manga Hardcover Volume 13

Kenshiro has crossed the only sea left on earth and arrived in the land of the Asuras to rescue Rin. It is a blighted place, ruled by a brutal code whereby only those who survive hundreds of deadly battles before the age of 15 are allowed to live. Although Kenshiro knows Jask is using Rin as bait to lure him and Falco into a trap, the two warriors won't be stopped. On his way to the Gate of the Asuras, Kenshiro learns about another rogue martial artist, a man whose Hokuto Ryuken style might just lead the land of the Asuras to salvation-or damnation!
