After a mysterious attack wipes out the major cities of 19th century Japan, Korea, and China, survivors from all three lands find refuge on a hidden island and build a new society. Hana, the orphaned daughter of Korean peasants, and Kenichi, son of a great samurai leader, have little in common except for a mutual disdain for the other. But these young warriors will have to work together when an army invades the island with shocking news: there is a new Shogun and the Island is expected to pay fealty in exchange for protection from a new enemy...a mutated horde that threatens to wipe out all humanity. Award-winning writer Greg Pak (Firefly, Mech Cadet Yu) and artist Giannis Milonogiannis (Prophet) present a story that examines how we move forward when our past divides, set against the backdrop of a post-disaster 19th century Japan.

Denied re-entry to the island, and with the combined forces of the Shogun and the bandits closing in, Hana and Kenichi prepare for the battle of their lives.

With enemies on all sides, Hana and Kenichi struggle to protect the island and themselves. But the Shogun has a more sinister plan brewing, and for anyone to survive this fight, Kenichi will need to rally the island's forces, and Hana will have to prove to those loyal to the Shogun that his way of life is not worth fighting for.

The war for the Island rages on—but in the heat of battle, will neither side open their eyes to the true threat bearing down on them, in the form of the Byōnin?
