* ArcFatigue: The chapters focusing on Asuna's monologues about her life after SAO have been criticized for being too long or being a series of WallOfText especially those who are waiting for the part where Asuna and Co. goes to rescue Kirito in ALO. It didn't help when the next arc was about Kirito's time in ALO which many felt should have been done earlier rather than making more chapters of Asuna.
* EnsembleDarkhorse:
** Yui, Silica, Klein, and Lisbeth took up the following placements to Kirito and Asuna in Knowledgeseeker66's popularity poll.
** The original character Hideyoshi has some popularity. This is most likely due to how he hates Sugou, and some readers find him more interesting than Sugou.
** Knowledgeseeker66's depiction of Asuna's brother, Yuuki Kouichirou, has earned a fair number of fans.
