Bandai Namco has published an official First Look Preview video of Unanswered//butterfly, the special Sword Art Online anime show that will be available via purchasing the Ultimate Edition of Echoes of Aincrad. It is available via the company's Southeast Asian YouTube channel with original Japanese voiceovers and official subtitles in English, Indonesian, and Thai.

Note that although the official video description mentions "20 minutes", this preview actually runs for just around 18 and a quarter minutes (with the last 20 seconds showing promotional details about Echoes of Aincrad).

You can find the video right below. Echoes of Aincrad will be released for PlayStation 5, Xbox Series X, and PC via Steam worldwide on July 10 (with Japan and Asia getting the console releases a day earlier).
