On this episode, Kirito's gang hangs out at the cabin in New Aincrad. Later, a flashback was shown of the raid fighting against 22nd boss and to also unlock the cabin.
So it was interesting to see Kirito and Asuna living their peaceful lives along with their friends. Also they revealed more nice extra details on what could have happened back in Sword Art Online. Now I'll be looking foward to see the new character showing up for this side story. Overall, interesting build up for the new plot.
Conclusion: Interesting build up for the next plot.
