Set in the Edo period, Gabimaru the Hollow—a legendary, nearly un-killable ninja—faces a pardon if he helps locate the Elixir of Life on a perilous island. A shogunate task force pairs death-row convicts with executioners, each duo racing to return with the elixir to win clemency. On Shinsenkyo, lethal trials, monstrous foes, and shifting loyalties force Gabimaru to confront his purpose, his past, and his will to live—driven in part by his love for his wife—in a dark, stylish blend of action, fantasy, and redemption.
