The Black Dragon Arc is the sixth major story arc within the Soul Eater series. Death the Kid and the Thompsons investigate the disappearance of many souls from a Baltic coastal town, leading them to not only the Kishin's Evil Spirit, the Flying Dutchman, but also Crona. In the aftermath, Kid learns a terrible secret as the anniversary of the DWMA nears. Meanwhile, Franken Stein and Sid Barrett investigate why Dr. Medusa is so interested in Maka Albarn and Soul Eater's blood, and in the anime only Ox Ford struggles to write a report on the annoying Holy Sword Excalibur.
