This is my personal favorite out of all of them as it not only gave us Azu, which is just a fun idea for a character to begin with, but also advanced the story the most out of all of them. Like, if anyone were to ever ask me if seeing the COVID episodes was necessary, I'd tell them that this one and, assuming they're willing to sit through them, the President Specials. Plus we got a step further in Horobi's' arc, with him refusing to admit that he's approaching Singularity himself.
