We all know that the juubi seen the 8.5 outta 9 beast chakra and then he looked closer at naruto and was quickly angered by the site of looking at the sage and the fact he sees a new reincarnation of the sage
From the sage naruto must be the power of peace he was inferring to and to the baby beasts
The gold and silver brothers are also a huge find because the fact they ate kuramas meat and had lived to have chakra of the ebast and was even able to talk while in v2 form and this also states there line sjust like naruto and even A said they could be distant relatives to the sage......and they might have lived during the time of uzumakgakure before it was destoried and by some weird thought the brothers might be the beast that attacked the village
Another great find was they easily used the sages tools for many years before there deaths
and with this the sage made them distant blood relatives of the Senju clan and as such, both were on good terms And even as of now there is more believe that Rikudou sennin is a uzumaki based on the fact he had a very long life and had extreme chakra preserve Members of this clan were very knowledgeable in the art of fūinjutsu,the sage was a god at fuinjustu and the fact the sage was respected, and feared to those corrupted hearted people worldwide because of his prodigious skills.
