Blade of the Immortal
What is the meaning of life if you cannot die?
Manji was a samurai bound in service to an evil master. When he chose humanity over duty and butchered his lord, he was forced to kill 100 honest men who made the opposite choice. At this point, when he had no future but death, he was granted eternal life by an old mystic. He spends his time taking care of his sister, who was the wife of one of the 100 men. But tragedy strikes Manji yet again, and he is driven to end his curse... and seek the gift of death.
