Some interesting points the elders revealed
- There are a lot of unnatural deaths inside the boxes.
- The red boxes we see in earlier episodes are made from brains cells of those who died in the boxes, or something like that. Bad taste.
There were a female(we only hear her voice from a communication device) conspiring with those guys in the moon just before they were frozen. So it might to be too early to say the third party is completely gone. I doubt they are going to introduce new characters at this moment. So multiple choice question: the voice belongs to (a) Kazane (b) Kaguara (c) Nina (d) None of the above( state your answer).
Tsusuji said something about "my empire". If I take her words literally, my speculation is that Kazane promised the moon colony to her( we do know that Kazane promised something BIG to her).
