Also to point out the Shinsu Senju thing Asura used was a type of measure for us fans to use. Basically with the help of 15 people, Asura got enough chakra to rival Sage Mode Hashirama. Basically thanks to this it helps my theory be proven more truer than ever before. Now we know how Asura got the chakra needed to use the chakra avatar state we see once again in this episode.

Glad we can finally close the case on the "Was Kurama the one to give Naruto and Minato chakra mode?" The answer...Kurama provided the chakra but it was Naruto and Minato's blood that provided the skill. A skill that Asura and Toneri both shared(in their own unique way).
