Another thing I saw on another forum regarding the difference between viz and scans.
MS:
JB:
Viz:
The original sentence: “妖刀”と理屈は同じ弱い者には扱えぬ......
So basically Viz is correct again, but I can definitely see why MS is so off, they most likely read the sentence as “the cursed sword and reasoning are the same”, but the correct way is “it has the same reasoning as a cursed sword”.
