Harusame

Harusame (春雨, Sword of Light in the English anime) was the personal sword of Amidamaru and later the main medium used for Over Soul by Asakura Yoh.

About
Harusame is a katana with a hilt wrapped in red cloth and a golden tsuba with indentions at the four corners and crescent markings on the sides of the blade. The scabbard is charcoal-black.

It is the greatest sword created by the blacksmith Mosuke when he and Amidamaru were kids. During the time, the two protected a group of orphans with Amidamaru fighting of bandits and would often break the swords he used. Because it was almost impossible for Mosuke to gain any quality steel, he could not forge one for Amidamaru, until one day he decided to use a small knife, the only thing he inherited from his father and created a katana.

It was believed that with Harusame, Amidamaru would never lose a fight and ironically he died fighting the one time he was unable to use it. Hundreds of years later it was put on display in a museum. Mosuke's spirit watched over the aged katana, often crying on it, until Asakura Yoh appeared and used Mosuke's spirit to repair the sword.

It has twice been broken since. The first time was when the spirit of a bandit Tokagero, who was killed by Amidamaru, stole it and used it against Amidamaru to get his revenge. After it was repaired again, Yoh never returned it and instead kept it, using it as a medium for his Over Soul with Amidamaru. The second time was when he clashed with the Archangel Michael and Mosuke was once again summoned to repair it.

After the Shaman Tournament in the year 2000 it somehow came into the possession of Tamamura Tamao who, when she snapped, used it to run amok in Tokyo for three years straight. Tamao would later use it as medium for her Over Soul with Dai Tengu.

Trivia

 * Its name Harusame means Spring Rain. It was named such when Amidamaru, touched by Mosuke's work, shed a tear on it and claimed it was a rain drop.
