魔道師二人旅～長壁と番人～ (Madoushi Futari Tabi ~Chouheki to Bannin~)

Background
Ah before their eyes is a long, long wall

Elluka Clockworker and Gumillia are on their way to Jakoku to search for the Twin Blades of Levianta, but are stopped by a guard when they reach a great wall he tells them that only people of his country can pass the gates. The mages then try to dye their hair black like his, but he tells them their skin isn't the right color. They then try to color their skin with mud but he tells them they don't have the right eye color. Elluka becomes so frustrated she blows the man away with wind magic. When they open the gates that lead to "The Great Country" they find nothing and Gumillia what the man was even suposed to guard.

This song was first released on the Nemesis no Juukou album.
