Is the Progressive vol 9 pt 1?

Reading the other Progressives Reki did pt1 and pt2 for some of the books and was wondering cause he said he was trying to stear away from that but wanted to know if it or if vol9 was covering the entire floor, if it was just pt1. Was wanting to look at the synopsis post but didn't want to spoil myslef with the story trying to look for the answer, so decided to just ask.
