As a weapon, it is a jet black needle that is extremely thin with a slightly thicker handle. On the handle, "Black March" is embroidered in cursive, written in a language similar to Japanese.

When Ignited, Black March comes to life. It assumes the appearance of a young lady with golden hair and pointed ears dressed in an elaborate red gown.  The needle is sexist as it prefers handsome males over other categories, refusing to listen to female users.
