She has sworn loyalty to Guest as Supreme Commander and handles communications between units and coordination for peace. While maintaining a dignified demeanor, she is quick to notice small changes in her comrades. She does not hesitate to recommend rest to Guest when they are overworking themselves. Her feelings for Shasta remain unchanged, and she cherishes the present they can walk together. "Supreme Commander, please leave the military matters to us as well," she says with a gentle smile.

After Kirito and the others returned to the real world, she followed Guest's decision to stay and remained in the Underworld herself.

The greatest pugilist in the Dark Territory. After Vecta's fall, he recognized Guest as Emperor and joined the reconstruction efforts leading the Pugilists. Boisterous and hates to lose.

Knowing Shasta's desire for peace, he helps bring both sides to the same table. When visiting the Dark Territory, he speaks casually with the soldiers.

An Integrity Knight who supports peace between the Human Empire and the Dark Territory. She often visits the Dark Territory to see Iskan, and has eventually become a bridge between both camps. She is a woman of few words and her expression rarely changes. However, she listens quietly to others and does not judge people by their race or position. She cooperates with the reconstruction led by Guest and walks the scarred streets with Iskan. "...It looks like it will become a good country," she mutters, as Iskan smiles happily beside her.

An Integrity Knight who remains concerned about the future of the Human Empire and the Dark Territory even after the war. At the invitation of Guest, who became Supreme Commander, she visits the Dark Territory to see the rebuilding city with her own eyes.

However, through talking with Shasta and Lilpilin, she learns that they too are people with lives they wish to protect. She sometimes clashes with Sinon, but they share the same concern for Guest. "Show me the future you are trying to build."
