On this episode, Yuki, Asuna and the raid finishes their battle against the final battle. Later, the raid celebrates and then Yuki dies at her final moments.
So as expected just like in the novel, Yuki dies. Also I'm actually surprised that they didn't focus much on the final boss battle. It was just like a quick glimpse. Other than that, I guess the finale was decent but I'll be really looking forward for the Alicization/Underworld Arc (which will be way better than the ALO side arcs) for the third season if it comes out. Overall, decent finale and little action.
Conclusion: Decent finale and little action.
