User blog comment:OverlordRocks/What is the plot of season 7? (Let's look at the facts, work together, and have everybody collaborate!)/@comment-27507964-20160326033600

One thing we haven't actually listed here yet it the sets. The significances I notice in the sets are Ronin's Mech from the video game. It is possible they just liked the model and they wanted to use it again, but there could be a darker side.

Although there are still two more sets to be revealed we still haven't seen Nya's new suit. Insignificant in my opinion.

The really interesting thing is little Nelson. He would not appear in a set if he did not appear in Season 7. They did not include Misako for ages; he must have SOME major importance to be included,
