So I was wondering why Yhwach isn't in the "Universal, possibly Multiversal" category. Or at the very least Solar System level? Star level? In my view this should be changed and here's why.
First off, I understand that the size of Hueco Mundo and Soul Society aren't known. However, the "world of the living" is supposed to be our universe. Bleach takes place in an alternate reality based on the real world. Places like Japan, Mexico, England, etc are confirmed to exist. The Moon and the Sun obviously exist. With so many parallels, it's safe to say that the Human World has a defined size, the same as ours. The burden of proof is on proving that the Bleach world isn't universe sized. This is independent of the size of the other worlds, mind you. It's just in relation to the world of the living.
If, for some reason, you choose to believe that the Human World isn't universe sized, Yhwach should still have a Solar System rating. The Moon and the Sun are shown multiple times throughout the series, so a solar system exists. I couldn't find panels with other stars being shown, but things are named after stars (Sternritters are literally Star Knights, among them is "The Superstar" with star-themed clothing), so stars definitely exist in the universe of Bleach and humans are aware of them. There is no reason to believe the contrary.
All of this can be concluded without getting into the size of Soul Society and their potential universe size. Though it's important to note that Soul Society has a day/night cycle with its Moon and Sun being shown, and Hueco Mundo also has a Moon.
I don't want to name any names, but other characters from other series have gotten ratings from attempting to destroy and recreate completely made up dimensions of unknown size. Their size were then gauged by background celestial bodies, not limited to the planet they were on. So why does Yhwach have to be at Planet level?
