I apologize if this has been addressed previously. As we are aware, Kurama is permanently deceased and cannot be revived like the three tails due to the complete depletion of his chakra in the fight against Isshiki. However, during the war arc, the Gold and Silver brothers had access to Kurama's chakra, enabling them to create a cloak. If edo tensai were to be used, would Kurama's chakra still be present? Can the brothers exhaust it? Or is it comparable to the chakra of Minato/Kushina, where a certain degree of contact is required? While bringing Kurama back would detract significantly from his sacrifice, is it true that not all of him is gone in that case?
