if she creates a barrier around her target and the sword is on top of the barrier she is effectively holding the sword.Lol what? How are her chains lifting the sword like did you really just say that?
Because kurama is the same size as the rest of the beasts. If he were to be half size he'd be smaller than the other beasts when in naruto's mindscape. Same reason why the rest of the beasts are actual size in naruto's head yet only 10-20% chakra wise.According to what? Its half Kuruma, why would he be 100% in Naruto's head?
