The official website of Blue Exorcist started a countdown on Thursday, which will expire on July 4 at 8:00 am Japan time. For now, we do not know further details about this mysterious countdown.

At the same day, it was announced from Viz Media and Aniplex that the creator of Blue Exorcist manga, Kazue Katō, will be a guest at this year's Anime Expo, which will be held from 1 to 4 July. By chance, the end of the countdown coincides with the Anime Expo that Katō will attend.

Maybe, her appearance at Anime Expo will not be so random? Does she hold us good news? Time will tell.
