Dororo

Dororo, a young orphan thief, meets Hyakkimaru, a powerful ronin. Hyakkimaru's father, a greedy feudal lord, had made a pact with 12 demons, offering his yet-unborn son's body parts in exchange for great power. Thus, Hyakkimaru - who was born without arms, legs, eyes, ears, a nose or a mouth - was abandoned in a river as a baby. Rescued and raised by Dr. Honma, who equips him with artificial limbs and teaches him sword-fighting techniques, Hyakkimaru discovers that each time he slays a demon, a piece of his body is restored. Now, he roams the war-torn countryside in search of demons.

Blade of the Immortal (ONA)

New adaptation of Mugen no Juunin</i>. Damned to wander the Earth in an endless cycle of carnage and murder, the fallen samurai known as Manji seeks the chance to win back his mortality. To do so, he must first balance the deaths weighing against him by slaying 1000 evil souls, a task that would take even the greatest warriors a lifetime. Manji, however, has all the time in the world to kill, and his lonely quest leaves a trail of bloody bodies in his wake… until his path crosses with that of Rin, who has sworn vengeance against the murderers of her family and school, even though the cost will almost certainly be her own life.

Samurai Champloo

Let's break it down. Mugen's a reckless sword-slinger with a style that's more b-boy than Shaolin. He's got a nasty streak that makes people want to stick a knife in his throat. Then there's Jin, a deadbeat ronin who speaks softly but carries a big blade. He runs game old-school style, but he can make your blood spray with the quickness. When these roughnecks bring the ruckus, it ain't good for anybody, especially them. Enter Fuu, the ditzy waitress who springs her new friends from a deadly jam. All she wants in return is help solving a riddle from her past. She and the boys are tracking the scent, but there's 99 ways to die between them and the sunflower samurai. (Source: Funimation)
