An alternate timeline of July 2015 goes like this: I submit a paper to ICALP and it gets accepted. I get to go to Kyoto in July. I take a week or two of vacation in Japan. I am able to snag a ticket to 10th with some help from my good friends. I go to M@STERS OF IDOL WORLD!! 2015 on July 18-19 and have a good time at my first live, seeing the 765PRO All Stars and the CGs and MLs, and meeting some cool people from the internet. I go leave Japan and go to Liverpool for my next conference. In our current timeline, only one of these things happened.
10th was a really great live for celebrating imas as a whole. Focusing on the 765PRO ALLSTARS on the first day was a great way of marking their 10th anniversary and incorporating Cinderella Girls and Million Live in the second day was a great way of marking the 10th anniversary of the series as a whole and for setting it up for the years to come. The only unfortunate thing was the decision or circumstances that resulted in SideM not being included. It’s understandable, since it was early for them, but they’d have been debuting just a bit later, so it seems like some unfortunate timing prevented them from also participating in this series milestone. It seems like DRIVE A LIVE playing on Day 2 is a bit of a concession on that point.
