Nope I am not blind.....Naruto is fully synched with his tailed beast. That is why Hachibi noticed Naruto's connection with Kurama before the cloak even transformed. Minato is not on Naruto's level. His cloak has not been upgraded, this is both Kurama's working together. That was the whole point of the fist bump.....
DKurama gave Naruto and his counterpart chakra so they can enter Bijuu mode...both Kuramas are acting as a whole
Yes I know Minato is for support because he can't use sennin mode...though again like the panel above clearly shows...Naruto went into Bijuu mode..and Minato stayed the same..
