Fist of the North Star, Vol. 13 (Hardcover) (manga)

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. Han, the general of the Asuras, sends his most brutal fighters to take them on, and Falco must face his greatest battle as the successor to Gento Koken.
