I think it's a message saying that the video was removed from nicovideo for some reason. I don't know enough Japanese to know the reason. However, I know enough Japanese to see from all the comments bunched up at the end that they are commenting on stuff in a video that used to be there. That video, incidentally, has been re-upladed again by some nip here:http://www.nicovideo.jp/watch/sm1573466
For example, one comment refers to ramune, and the original anime had ramune.
That said, since the superior Makoto is in RahXephon, a nice boat is very appropriate.
