Arc 18Mist Island and the Black Knight
Luther defeated Leomaster on Mist Island, overcame the divided personality the island created, and advanced to Black Knight. After reaching Toscarter Island with Anderson, he began planning a fleet to target pirates and Loen officials as he pursued revenge.
- Luther and Anderson killed Kircheis and discovered that the Death Announcer worked with Agalito, then followed a message from a trapped Aurora Order saint toward Mist Island.
- Luther entered Leomaster’s dream and learned that the island divided people into opposing personalities, while Barros Hopkins arrived seeking the black key.
- Luther confronted Leomaster in the island’s fog, used the Abyss Card and Medici’s power to fight him, and killed the Saint of Darkness with a Flame Spear.
- Mist Island split Luther’s personality, but he caught and devoured his despairing double before escaping as the island dissolved.
- Bernadette identified the black key as belonging to Roselle’s Black Throne, and Luther used Leomaster’s characteristic and Grigel’s Shadow Trace to become a Black Knight.
- Luther and Anderson reached Toscarter Island, where Anderson collected the bounty on Kircheis and two other pirates while Luther registered as Alexander Gascoigne.
- Anderson explained the pirate kings and generals, and Luther decided to target Tracy and investigate the force behind her.
- Luther invited Anderson to become the first mate of a fleet aimed at pirates and Loen officials, and Anderson asked for time to consider.
