This is a bit of late news, but hey, better than not informed aren't we?
There is going to be pre-airing stream of episode 1 in Nico-nico, Bandai Channel and one more site that I couldn't remember. Time and date: 23 September, 6 pm ~ 7 pm, JPT. It's a livestream, so far that I know, so make sure people who are planning to watch them go to the site a wee bit before 6 pm! And setting up those streaming thingy ofc...
It sucks that I won't be able to view the livestream thanks to trashy net at that time
Ah well, will wait for someone to rip it and sneak upload it without Aniplex knowledge~~
P.S: Any mistake please correct it! I'm having serious jetlag with iPhone as my connector orz
