With great sacrifice, the Arabakia Kingdom Expeditionary Force succeeded in retaking Alterna, but Haruhiro finds himself crushed under the weight of what he's lost. The ambitious General Jin Mogis of the Expeditionary Force, the survivors of the Volunteer Soldier Corps, and the mysterious residents of the Forbidden Tower. In the middle of these different factions, each with their own goals, Haruhiro's party has one of their own members taken hostage, and are forced to go on a dangerous mission. Incredibly, their goal is… an alliance with the goblins?! As the team struggles, unable to find a way out, the man who once shared their joys and sorrows, but was forced to go down a different path, reappears! Now that Haruhiro and his party have lost their memory once more, the bonds they formed in Grimgar will become their strength.
The second volume in the endgame arc. It starts off well, he find out that Haruhiro is now made one of the mentors of Thieves Guild like Barbara. After that point, the story becomes very boring (particularly thy starting parts of infiltration of Damuro) but it picks up the pace when we get our history lesson.
We find out about the establishment of the Kingdom of Arabakia and get to know some lore about the noble houses. Finally, we know who Enad George is (mentioned by Jessie, in which he refers to the No Life King's curse as the Curse of Enad George).
Since then, the story gets good and the group starts suspecting Shinohara at the end. We see how Leslie/Master Unchain starts influencing Mogis and Volunteer Corps. Setting things up to further whatever his plan is.
