Amidamaru

Amidamaru was born on January 6, 1385 in Japan. As a child, he trained to be a samurai in order to drive away bandits to protect the orphans with whom he was living. However, his katanas frequently broke because he was too poor to afford quality steel, and he refused to steal katanas from the corpses that were found scattered across the land. His friend, Mosuke, being a very skilled swordsmith, was able to make a katana using his own father's knife. After Amidamaru shed a tear in gratitude, he pretended that it was the rain and the katana was named Harusame (lit. "Spring Rain").
