you still have not noticed it? that Tobi is Madara himself
Japanese mythology Izanami (Rikudou) bron his children Kagutsuchi, Amaterasu,Susanoo Tsukiyomi,Ebisu
but Kishi maked the Japanese mythology as Jutsu and the character became other names
Rikudou Sennin (Izanami) is praised as the founder and creator of all Ninjutsu, which would seem to imply that he's the creator of the Ninja way of life.

Japanese mythology Kagutsuchi(Juubi) is a fire god deity of Japan who burned his mother-(Izanami) to death when Izanami(Rikudou) gave birth to him.
Izanagi, in his grief, beheaded Kagu-tsuchi with his sword, Ame no Ohabari (天之尾羽張), and cut his body into eight pieces 8 Bijuu?s kishi maked Inari< is a fox= Kyuubi as the 9 tail he was a god like Kagutsuchi(Juubi)10 tail.Its the same what kishi did The Rikudou Sennin sealed the juubi within himself, becoming the world's first jinchuuriki. The power of the juubi was so great that when the Rikudou Sennin died, the juubi would escape instead of dying inside of him. Knowing this, the Rikudou Sennin split the juubi with Izanagi and who created 9 other Bijuus as Reality.

Kishi changed much things but I like kishi story more as

Japanese Mythology Amaterasu goddess of the sun and fertility who brings light to the world Amaterasu,ruler of all gods.after Izanagi is dead.

One day Susanoo looked around his sister's garden, and finding no one around, had a bad idea to show off what the could do. He blew strong winds and scattered Amaterasu's beautiful flowers all over the area. Having seen her garden totally ruined by his misdeeds, Amaterasu was deeply saddened, and hid herself in a cave behind a thick, heavy rock door. The whole world became completely dark and very cold. Days and weeks passed without sun, and everybody became sick and depressed. One day a female deity said, "I cannot stand this anymore. I will dance to cheer you all." So she started dancing a lewd dance. Then musicians started playing enticing music with drums and instruments. The dance and the music were so outrageous that everyone began laughing out loud. It turned out to be a big party in the darkness.

Meanwhile, behind the rock door in the cave, Amaterasu heard the strange noises outside and wondered what they were. She approached the door, and found that the noise was music. She felt that something interesting must be going on outside, so she came even closer to the door. Outside, the strongest deity was awaiting for that moment. as soon as he saw the first line of light coming through the rock door, he pulled on the door with his full strength. Amaterasu came out and shined again and order was restored. The was the beginning of the country of Japan.

original mythology Susanoo&(a girl) Sakura< like kishi said by her she has no goddess a normal girl ) brings Amaterasu to the light
I'm sure kishi will change it and it will be Itachi&Naruto who bring Sasuke to the light.

Kishi will doing the same things Sasuke will brings light in the world and will become
as the next Rikudō(this is why we saw 2 times Rikudō on Sasuke) and who will
suppress all gods was said by the Japanese Mythology.

And this why Sasuke is the reborn of Rikudō you can read
the Japanese Mythology.
