User blog comment:ChocolateSquirrel/Filler Arc Predictions (more like speculation)/@comment-25334245-20140929231124/@comment-25334245-20141003024142

My post said flashbacks in general. The s class was an example of something that I would like to see in a flashback, while you would like to know more of the spirits While to me, we saw many different spirits in their world, and it will not bother me if they are not all introduced. We all have different tastes and preferences and neither are wrong.

And yes, it would be interesting to know more about the celestial spirits that we know, perhaps they will touch on some things in the upcoming filler.
