Hello, Asuna! Enjoying your scree time? Welcome to Tentacle Art Online!
Personally, I think this episode was just to give Asuna more screen time and to pander to a new set of fetishists. In my opinion, it really doesn’t tell us anything new as most of the info shown in this episode have been disclosed by the villain himself at the beginning of the arc. The parts that mattered were only the final moments of the episode where in Kirito suddenly goes “MUST SAVE ASUNAAAA!”.
Oh well, hopefully the anime will show something new next episode.
