'Naruto Shippuden' updates, spoilers, rumors: Is there another Otsutsuki clan member?

The previous episode of "Naruto Shippuden" featured the backstory of Otsutsuki Kaguya and her twin sons, Hagoromo and Hamura. While the recent episodes of Masashi Kishimoto's highly popular anime series are fillers or non-canon to the original manga version, they revealed the untold narrative of the mysterious Otsutsuki clan member who fell from the skies to go after the Divine Tree. Also, the previous episode gave the viewers an idea about Kaguya's motivation in gathering human sacrifices for the Divine Tree with the use of her powerful third eye, the Rinne Sharingan.
Episode 462 of "Naruto Shippuden" titled "I Created the Past" showed the Sage of Six Paths, Hagoromo, confronting his own mother with regards to the Divine Tree. Hagoromo insisted on his mother that they need to stop sacrificing humans to the Divine Tree, but Kaguya staunchly disregarded his son's plea. The Otsutsuki matriarch and the so-called "Rabbit Goddess" claimed that the Divine Tree ritual is needed because she is getting herself ready for the arrival of "The Others."
Kaguya claimed that these individuals which also belong to the same place where she came from are vicious, and they are only after power. In a particular scene, there are three Otsutsuki clan members shown besides Kaguya. The two members appear to be the characters already introduced in the "Boruto" movie last year, Kinshiki and Momoshiki. The end of the movie showed them to have died in the hands of Naruto, Sasuke and Boruto. However, the other Otsutsuki has not yet been encountered in the series and the previous "Naruto" movies.
Many users at the Gamefaq forums have discussed the mystery of the other Otsutsuki clan members that led Kaguya to create the White Zetsu army. It was first thought that "The Others" were actually Kaguya's relatives, Momoshiki and Kinshiki, who were first introduced in the "Naruto" universe through the "Boruto" movie. However, the two were already dead and there are doubts if they were the beings Kaguya had always feared of. There are speculations that Kaguya's real enemy that is far more powerful than her has yet to be introduced in the stories, and the current "Boruto" manga series may introduce the greatest threat to the shinobi world in the future.
