I Need To Order A Physical Copy Or Find An Audio Book Version - Tumblr Posts

In another translation of the fanbook the question is if the Inumaki family are the last cursed speech users left in the world... which is a very different question from this so how could it be translated so differently? Also, in the Thorny Road At Down novel, the cursed speech user Nobara and Toge are facing said that he learned ONE of the Inumaki family's cursed speech users is in Jujutsu High; meaning there are more. So I suppose this right here is the mistranslation?
