For those wanting to see the previous 2 occasions:
- #509 (2009/05/22)
- Mori-D no Ie Kara 2010 Saikai (it's a Season DVD extra)
The first time was pretty messy too, the second time it was less messy and only 1 year after the first clean-up.
I think they really throw some extra stuff in to make it look worse, but this time it looked really bad, especially the bathroom. But I thought the amount of footage inside the apartment was so little compared to the amount of a mess it was. Why go to so much trouble and only show like 10 minutes of it? I have a feeling we might see a continuation of this later on, since we didn't actually get to see the final fully cleaned-up apartment in the end.
What if the punishment game for the Idoling!!! vs Idoling NEO single battle is further cleaning up his apartment? Which was in fact the original punishment for the first clean-up, when it was also a battle between teams to get the highest selling single. It's just a wild guess but the timing might be right, but then again, why already show an episode with it? I'm more inclined to think there will be another episode with part 2.
