Warmth of the Heart (Aincrad 48th Floor, June 2024)
Elucidator was first introduced when Lisbeth checked its name, to find it was not a player made weapon but a boss drop, and Kirito requested a blade of equal quality. It was then used to test the strength of Lisbeth's best sword, which broke upon striking Elucidator.
