I am still clueless as to what the condition is for Yuta copying other CT's could be. Bc in JJK 0 he just kinda uses Cursed Speech and its not really explained. Sukuna's quote about him eating his finger makes it seem like a condition for using his technique. Kinda iffy but it makes sense given Yuta's list of opponents. If we take JJK 0 out of the question then Yuta must have eaten Inumaki's arms when they got blown off lol
