Savior gaspard predicted a disaster called "the robbery of original sin". As a result, the sacred flame and the cold leaves joined hands to form the wings to break the sin. The wing of breaking sin has been constantly absorbing elites from all over the mainland for training to eliminate the original sin robbery. On the recommendation of the Global Geodetic System, Western Sahara joined the Crime Squad. During the training, the leader of the new SEED in Western Sahara repeatedly got into trouble because Karin insisted on her own fighting method. Western Sahara admired her and helped her out again and again. Finally, the stubborn instructor Lafarie Weng only gave in.

With the awakening of the dark original sin badge, the original sin robbery began. The new seed led by Western Sahara cooperated with the old Germany led by Reims and successfully sealed the first original sin badge.

Feng's second original sin badge was possessed by Satarudo, the mercenary king of Chengnaru, and refused to hand it over. In order to win the badge of original sin, the wing of breaking sin sent people to Chennault to participate in the competition. In the competition, Jiuyin, who was deeply loved by Cesar, was seriously injured by Satarudo. Cesar calls back Black Flame, defeats Satarudo, and helps Karin seal Feng's original sin badge (unsuccessfully, the black bride finally appears and seals the original sin badge).

The other four original sin badges were also sealed one after another, and the original sin robbery ended, and the broken sin wing retired and was officially dissolved.
