Before the series ends (will review the last two episodes on a single post once my source releases ep 13) and since this is Japan, we have a baseball-related episode! But this is not just any baseball-themed episode, we are back with Yukitaka, now with his teammates!
Probably the weakest episode in the entire series, in short filler. It is basically that they are in a space created by someone thoughts because he or she is in stress due to the championships. So why I decided to talk about it? Simply because that Yukitaka is back and the Prince is here to troll Yukitaka for good times sake... well, supposed to be until this whole fiasco happen! Also, those baseball loving Disconians are back. So yeah. That is the only thing that is special in this episode.
Overall, the only thing that is interesting in this episode asides from the ones mentioned above is the concept about that there are supernatural forces existing in the Level E Universe that is not aliens. Period.
