I didn't even realize that jujutsu was a category of jutsu in naruto, my brain just automatically thought of jujutsu kaisen because i dont speak japanese and they have the same word in the name... that is interesting... it is odd that we haven't seen any more curse jutsu techniques because from what weve seen of them they are very powerful and do not require hand signs, such a powerful category of jutsu not having any other techniques despite being so useful is strange...
