Sword Art Online. Volume 25. Unital Ring IV

Kirito cannot recover from the shock after his chance encounter with Eolain, as this masked man with eyes and voice reminds him of his late friend. However, the events affecting both virtual worlds do not allow Kirito to indulge in... emotions. — Perhaps all this is the beginning of a new war of worlds. After two hundred years, signs of an impending conflict are again noticeable in the Underworld. Meanwhile, a decisive battle against the "Society for Virtual Research" led by Mutasina approaches in Unital Ring. She commands an army of a hundred players enslaved by the dreadful magic of the "Noose of the Cursed." Kirito and his friends will have to think about how to respond to the huge difference in power.
