 Three Scrolls contain the secrets of creating the Zantetsu Sword(Goemon s sword). They were first stolen by Arsene Lupin the 1st in the 19th Century. Arsene Lupin the 2nd stole a dagger with the same cutting ability the Zantetsu Sword had. He was challenged by a Swordsman(who is Goemon s master later on), but lost during the duel. But he stole the scrolls from Lupin the 2nd for himself. Now Lupin the 3rd wants to steal them back to regain his family pride. But Goemon and Fujiko also want the scrolls.
