not commenting on the subject itself but this doesn't necessarily shoot down anything higher if the cosmology allows for it there have been things like marvel writers saying the omniverse is just infinite universes (believe Al Ewing said this once) when we know it's significantly more than that. Transformers is largely portrayed as a single multiverse even though there's consistently been material (obscure, but it's there) that makes it out to be a lot more. So Kamachi just saying it's just one universe while simultaneously including a bunch of other weird shit, it's possible for ToAru to be stronger by obd standards, if said weird shit meets the requirements
