I’m only half serious, the other half is me being a mrk.
But to sum it up shortly, as you can tell by the ratings I proposed and got accepted “3-A, possibly Low 2-C” I’m not even a firm believer that Low 2-C is concrete (hence the possibly). Bleach is already vague as it is, and I find multiversal Bleach to be quite a generous leap to grant Bleach with its vagueness (not to say I don’t think solid evidence exists for uni Bleach tho, ofc that ain’t the case, I upgraded the verse). Also, to be blunt, I think a lot of people see more than 1 realm and just preemptively jump on the “more than 1 realm = more than 1 universe = multiverse = 2-C” when that isn’t inherently the case. I view it in the same vein as claiming “Kaguya is 2-C because she’s gonna create/destroy multiple spacetimes with her ETSO”.
