Good evening. Sorry for all the confusion concerning the release of the trailer that I mentioned for next month. So I will give a prediction on when to expect it. The next trailers will be released in December.
On the 10th> New video
On the 18th> Final
On the 21st> A 30 seconds commercial movie (for theaters)*
I am planning it because it is still in progress. So it is undecided until its proper release time. Well then, until next month.
*Previously, after the release of the Together trailer, Nomura tweeted that he was working on a separate version for Japan.
