Samurai Deeper Kyo: v. 4 by Akimine Kamijyo
Tournament of Scoundrels: Tokugawa Ieyasu, recently instated shogun of all Japan, is holding a tournament in the capital city of Edo, and the fiercest warriors in the country are converging for the fight. The winner walks away with a fortune in gold, the shogun's blessing, and a pardon for any criminal history. The losers...well, the shogun isn't one to hand out consolation prizes. Demon Eyes Kyo has entered the tournament, but it's not fame or fortune he's after - he wants the head of Ieyasu himself!
