is it possible to have a hatsu that cancels out other peoples nen? besides specialist i don't think it is possible for someone to have a nen that cancels out other peoples nen and if possible how would it work? i had an idea from the manga boku no hero academia mangas home room teacher the eraser, it cancels out all nen in a are but then i realized that is emission and emitters cant change quality of arua like transmuter so do i need both and if i do what is the range? what are your thoughts
