Ox is searching for the legendary sword Excalibur in order to write a report about him. However, upon meeting him, he discovers that the holy sword is not quite what was expected, forced to listen to the sword's one thousand provisions as well as his tales. Excalibur tells about his times when he was resided in a ghettoized city, when he performed at an opera house, when he incorrectly solved a crime case, when he accompanied an expedition into battle, and when he suffered a heartbreak from his first love. Excalibur ends up singing a song about himself, and later gave Ox the opportunity to be his partner. However, Ox chooses to abandon him, negatively commenting on his personality.
