Under that logic even the RM from Nasu are universes or worse , Mundus illusions
Of course, that's precisely the problems with shit like that because by consequence, alot of the smaller shit can also be stated to be Universal by the same metric and to say that would be an absolutely stupid way to do so is an understatement.
It's why I reneged on the Planetary Bleach because people stupidly tried to springboard it into Universal and Multiversal with zero basis at all past "They each have Stars and a Sun" as if that matters for many, many reasons(We are sitting in a Solar System with multiple Planets orbiting around a single Star and have multiple stars around us? Universal Planets?).
I will gladly accept Planetary Bleach, I absolutely do not agree with anything above it at all past potential Multi-Planetary.
