All the way back to the chapter Obito went back to Madara to learn about the Eye of the Moon Plan in that flashback. She was hinted ever since then. Not really. All that was shown was the Ten-Tails and Hagoromo. The first time Kaguya was mentioned in the manga was when Madara told Hashirama about the origin of shinobi, when Obito unleashed the Ten-Tails' tree form.
