Brother forbidden underworld magic or not it literally DOESNT MATTER

other people have already explained you can't hand wave anti feats with "Mana affecting Mana", this just once again means that despite apparently being beyond literally EVERYTHING it's effected by something lesser

not to mention would this not temporarily make Mereoleona a 1-A being? She shouldn't be able to exist in the reality without it all collapsing (Hell mana shouldn't be able to exist at all in the physical world if it's ALL 1-A). Another problem, this would mean that literally every character who manipulates and uses Mana has the potential for 1A.
Stop the wank

we like BC but this is RIDICULOUS
