Rebecca Silverman of the Anime News Network noted that the series has “its own unique take on what has become a subgenre of fantasy” when compared to the previous Sword Art Online and the earlier .hack series. With respect to the anime adaptation, Silverman noted that one of the major drawbacks was the artistry. She held the designs of the characters with small regard, calling them “somewhat bland and generic in design, which is a bit of an accomplishment given how many character creation options there apparently are”. She used the design of Akatsuki as an example, explaining that the character’s beauty has to be constantly reminded to the audience despite the fact that “she’s one of the less striking female characters on screen”. Another issue Silverman pointed out was the apparent overuse of Naotsugu’s perverted nature for comedic relief and finding that for some viewers he may be “line-crossingly obnoxious”. Despite these drawbacks, Silverman remarked that the “show shouldn’t be dismissed as ‘just another ripoff’ before giving it a chance” since “it has the potential to expand rather than rehash the basic premise of players trapped in a game”.
