For a long time, I have been analyzing the rikudou related powers related to Kaguya and her lineage. This has been mainly for the purpose of trying to make some sense of Naruto's RSM, but there are also some other controversies in the community pertaining to these rikudou powers. Here is a breakdown that I have come up with that could potentially explain some things. Before I get into that however, I want to make one thing clear (that I know for a fact):
One more thing: In this thread, I will refer to rikudou senjutsu and RSM (six paths sage mode) as two different things. You will see why later.
Now without further ado, let's get into the break down:
1. For starters, we know that Kaguya's power is essentially that of Earth's shinju. By eating that chakara fruit, she obtained the rinnesharingan and several other kekkei morra, as well as extremely powerful chakara. When she merged with the shinju, she became the juubi. We also know that Kaguya possessed the byakugan.
(Here is where the more theoretical parts start)
2. Hagoromo did not inherit Kaguya's byakugan trait. However, he did inherit a diluted version of her rinnesharingan, which became the rinnegan. Furthermore, he inherited his own unique diluted brand of rikudou chakara, which is diluted from Kaguya's chakara.
3. Hamura did inherit Kaguya's byakugan trait. Furthermore, he also inherited his own unique brand of rikudou chakara that is also a dilution of Kaguya's chakara, but Hamura's brand is different from Hagoromo's. Hamura's brand of rikudou chakara caused a reaction with his byakugan that ultimately caused his byakugan to evolve into the tenseigan later in life (basically, I am saying that the tenseigan is basically a byakugan mutation that is caused by Hamura's unique brand of chakara, which would explain why Kaguya didn't have it. It has to be Hamura's diluted brand). Hamura's chakara may not cause this evolution in all byakugan eyes as seen by the fact that Hinata received Hamura's chakara, yet no tenseigan. Of course, it technically isn't too late for Hinata to awaken it since Hamura himself was implied to have awakened it later in life, so for all we know, the same could happen to Hinata (though I doubt it will). However, the fact that Toneri awakened it almost immediately upon taking Hanabi's eyes does pose somewhat of a mystery in this matter.
4 (controversial). Hagoromo and Hamura both obtained rikudou senjutsu by simply learning senjutsu (no bijuu chakara necessary, and remember, rikudou chakara =/= bijuu chakara). Now hear me out on this one. Even if we completely ignore the anime filler, the manga still confirms that Hagoromo personally knew Gamamaru (on a first name basis) and even received prophecies from him. Every person we know who has received prophecies from Gamamaru has been a toad sage or someone affiliated with Myboku (such as Jiraiya, and Naruto). Therefore, it is feasible that Hagoromo (and by extension Hamura) learned senjutsu at Myoboku at some point. The senjutsu mixed with their rikudou chakara produced rikudou senjutsu.
Again, I must reiterate, rikudou chakara =/= bijuu chakara, and Hamura was never even a jinchuuriki, yet we know that he had rikudou senjutsu too.
Basically, what I'm touting is that, rikudou chakara + senjutsu = rikudou senjutsu (not necessarily RSM mind you).
Now let me address a certain counterpoint pertaining to Madara that someone might come with:
"Alive rinnegan Madara with Hashirama's sage mode had rikudou chakara + senjutsu, yet he didn't get rikudou senjutsu until he became the juubi's jinchuuriki".
True, but I assert to you that Madara didn't really have enough rikudou chakara, or it didn't really flow through his body in the right way. Allow me to better explain what I mean:
Madara obtained his rikudou chakara by taking a small piece of Hashirama's flesh and injecting it into himself (thus mixing Indra's and Asura's chakaras and producing Hagoromo's chakara). While this was enough to awaken the rinnegan, I feel like it was only enough to awaken the rinnegan, and that the rikudou chakara just went straight to his eyes and stayed there.
Obtaining rikudou chakara from a small piece of flesh is different from actually having rikudou chakara flow through your body naturally like Hagoromo, or receiving a large quantity of it in bulk directly from the source like Naruto/Sasuke. The things that I am saying can best be understood if you look at some key differences between Madara and Sasuke.
Madara mixed in a small piece of Hashirama's flesh (Asura's chakara) to obtain his rikudou chakara, and in turn, he awakened a standard dual rinnegan, and it literally took him a lifetime in order to awaken it.
Now let's look at Sasuke. While Sasuke did receive Hashirama's cells from Kabuto, he also received a large quantity of rikudou chakara from the source himself (Hagoromo). What did he get in response? In turn, Sasuke awakened a seemingly more advanced rinnegan (a tomoe rinnegan) and he also awakened it immediately (unlike Madara who had to wait for decades). Furthermore, Sasuke's rikudou power actually showed in some of his other jutsus (such as the black rikudou chidori), whereas pre-jinchuuriki Madara never showed any rikudou power in his non-dojutsu oriented techniques (though I will admit that this could be because the rikudou effects only seem to show in raiton, which Madara never actually used aside from using a few storm element techniques once he was already the juubi jinchuuriki). It should also be noted that Hagoromo himself did not have to wait until the end of his natural life span to awaken the rinnegan. He too, awakened it as a relatively young man, unlike Madara.
What is the point I am making here? Basically, I am saying that the way in which you obtain rikudou chakara (being born with it, mixing in DNA, receiving it in bulk, etc...) may very well actually make a difference in the power you exemplify (because let's be honest here, anybody who is not delusional could clearly tell that there is a major difference in power between rinnegan Sasuke and pre-jinchuuriki rinnegan Madara). This could explain why Madara didn't obtain rikudou senjutsu upon absorbing Hashirama's sage mode. In short, Madara's body didn't really flow with rikudou chakara at the time. It simply had the trace amounts that were necessary for rinnegan.
Anyway, now we can move on with the break down.
5. Hagoromo had Indra and Asura some time after he had already become the juubi jinchuuriki. Now let's start with Indra since he is the easier one. We all know that Indra inherited the sharingan. Now the source of his sharingan is kind of debatable. I can think of 4 possible reasons as to why Indra inherited the sharingan, and I will get into them in this spoiler tag.
Either way, it was certainly feasible for Indra to have sharingan.
6.Now here is the hardest and most controversial one. Asura! We know that Asura somehow ended up with RSM (notice that I am using RSM this time, and not just rikudou senjutsu).This is the same RSM that Naruto got. Well, remember how I proposed that Indra may have been influenced upon conception by the juubi? Well, now I am proposing that Asura may have also been influenced by the juubi, but in a different way than Indra. Instead of inheriting the eye power of the juubi, I am proposing that Asura inherited dormant residual juubi chakara (which is the mixture of all 9 bijuus' chakaras). In addition, he later received a powerup from Hagoromo. The combination of this residual juubi chakara, and Hagoromo's chakara gift led to the formation of RSM.
Now, I ask you all to please put aside any personal biases and consider this:
This explanation would actually make a number of statements and facts make sense and properly coincide with each other. For example:
Having Asura's RSM be due to the mixture of residual juubi chakara within him and a chakara gift from Hagoromo, would directly coincide with how Naruto gained RSM (he received chakara from all 9 bijuus (which is juubi chakara)), and then he received a chakara gift from Hagoromo.
This would also make sense of Hagoromo's verbal statements. When talking to Naruto, Hagoromo actually said that eventually Asura's own chakara bloomed and he achieved a power to rival his brother's. This chakara that bloomed could refer to the residual juubi chakara that I speak of. Then later, Hagoromo said that he entrusted everything to Asura, and that now he entrusted both Naruto and Sasuke. This implies that Hagoromo also gave Asura a powerup in the same way that he did for Naruto and Sasuke.
Having Asura's RSM be juubi chakara + Hagoromo's chakara would go perfectly with that sequence of statements.
So that's my theory in a nutshell about rikudou senjutsu vs RSM.
Rikudou Senjutsu = Rikudou Chakara + Senjutsu
RSM = Rikudou chakara (or Hagoromo's specifically) + juubi chakara (or chakara of all 9 bijuus)
Now it should be noted that RSM is a derivation of rikudou senjutsu (since juubi chakara seems to automatically give you senjutsu as well, as seen when Madara and Obito became the juubi jinchuuriki). However, rikudou senjutsu does not necessarily imply RSM. Think of it like this: All thumbs are fingers, but not all fingers are thumbs. It's like that, but replace thumbs with RSM, and fingers with rikudou senjutsu. Therefore, when Madara made the statement "Naruto awakened the senjutsu of the six paths, Sasuke awakened the rinnegan, I have both of those powers", he was still accurate.
Now you may be wondering about some things like:
Rikudou Madara possessed juubi chakara + Hagoromo's chakara. Why was his mode not the same as Naruto and Asura's.
My answer: The mazou. Even though Naruto and Asura (according to this theory) possessed juubi chakara, they were not actually the juubi jinchuuriki and did not possess the mazou. We know that the mazou possessed its own chakara, as seen by the fact that old Madara was able to keep himself alive by tethering himself to the mazou and living off of its chakara. In fact, it is the sheer life force of the mazou that keeps a juubi jinchuuriki alive after the tailed beasts are extracted. It is clear then, that the mazou has some power and influence. This is what makes it feasible that actually being the juubi jinchuuriki (mazou and all) grants a different form from Naruto's and Asura's RSM. However, Madara and Obito's form can still be considered as like an advanced form of RSM since they do have Hagoromo's chakara + the juubi's chakara.
Note: I know I said that Madara only had traces of Hagoromo's chakara, but using a jinchuuriki mode amplifies even one's own chakara. For example, when Minato and Naruto teamed up and used ftg to warp everyone outside of that barrier, several shinobi stated that they sensed specifically Minato and Naruto's chakara. Note that they didn't just say Kurama's chakara, even though they were all surrounded by Kurama cloaks. They also sensed Naruto and Minato's chakara as individuals. This shows that jinchuuriki forms don't just amp up and use the bijuu's chakara. They also amp up the individual's own chakara as well. This is also highlighted by the fact that when a jinchuuriki goes bijuu mode, they meld their chakara with the bijuu's chakara, and both chakaras become stronger as a result. Having said that, when Madara became the juuubi jinchuuriki, the traces of Hagoromo's chakara that he had would have amped up to be a significant amount. Also, this would have been the case with Obito as well. You may be wondering, "Where did Obito get any traces of Hagoromo's chakara?". Well, Obito at the time had Madara's rinnegan which contains Hagoromo's chakara.
Now, you may also be wondering, "What has Naruto been using all this time?".
Well:
In the war he only used RSM.
As an adult, he uses rikudou senjutsu. That is why his mode lacks the pigmentation despite using senjutsu. Now you may say that we've seen the Last Naruto and adult Naruto (while not using Kurama's chakara) use regular toad SM (with the pigmentation). Yes, that is true. Naruto never lost access to toad sage mode just because he gained rikudou chakara. Naruto and Sasuke can choose to use or not use rikudou chakara in their jutsus (as seen by the fact that we saw Sasuke willingly make his chidori black, while we've also seen the same Sasuke use normal chidori). That is why Naruto can still use base toad SM and BSM with pigmentation. He doesn't have to add his rikudou chakara to the mix.
Now, before you say, "Rikudou Senjutsu has the rinnegan symbol on the back and 9 tomoe", remember that Naruto, Madara, and Obito were using not just rikudou senjutsu, but RSM when they had those symbols on the back. As for Hagoromo and Hamura, those rikudou cloaks were actually just their base clothing. They wore those cloaks casually even when not using any power whatsoever. In fact, even Indra and Asura wore those cloaks (and Indra never used rikudou senjutsu or RSM).
You may also say that Naruto used RSM without the cloak and the rinnegan symbol and all when he kicked Madara's truth seeking ball. Well remember that Naruto can display that he is using a small amount of bijuu power (without going into any cloak) via a small change in the eyes. He has even shown this with Kurama.
Remember this:
or this:
These were examples of Naruto tapping into Kurama's power and displaying it via the eyes without going into a cloak. If he can do that with Kurama's chakara, then why not all 9 bijuus chakara? That would explain his "base RSM" when he kicked Madara's truth seeking ball.
If you say that Naruto's skin doesn't glow for RSM, you're right. Like I said though, he hasn't used RSM as an adult. He has been using Rikudou Senjutsu as an adult, which doesn't actually change one's appearance as evidenced by Hagoromo and Hamura just being in their base clothing and no special cloaks upon using it. (Once again, I remind everyone that Madara and Obito's forms were also advanced RSM due to the presence of the mazou, in addition to being rikudou senjutsu since RSM is a derivation of rikudou senjutsu). Therefore, Naruto can use Kurama's power with the rikudou senjutsu if he wants to and have his skin still glow even though he is using rikudou senjutsu.
As for the truth seeking balls, adult Naruto should technically be able to produce those even in his base looking form (using rikudou senjutsu though). After all, Hagoromo and Hamura produced truth seeking balls in their base looking forms (rikudou cloaks are their base clothing).
Anyway, that is my theory break down in a nutshell.
Hope you enjoyed. Discuss.
Rikudou chakara and bijuu chakara are not the same thing!!! We have seen several instances in the manga that prove this. For instance, when Obito jabbed his hand into Rikudou Madara's chest, he stole some rikudou chakara and formed a truth seeking ball even before he even touched any of the bijuus' chakaras. Later, he gave all the bijuu chakara he had (Shukaku, Gyuki, and yin Kurama) to Naruto, yet he still had rikudou chakara (which he later gave to Kakashi). Kakashi even proved that Obito gave him rikudou chakara by producing a black raikiri (we know that rikudou chakara can make raiton turn black and more powerful). Yet, did Kakashi have bijuu chakara? No! He had rikudou chakara! Also, Obito's truth seeking ball was still seen with him in kamui's dimension even after he gave all his bijuu chakara away to Naruto.
Another example of this concept is seen in the fact that Sasuke outright stated in the fight against Rikudou Madara, "I also possess the power of the six paths", and then he proceeded to produce a black (rikudou enhanced) chidori. Yet he had no bijuu chakara at the time.
There is also the fact that there are different brands of rikudou chakara, as seen by the fact that Hamura has rikudou chakara, but his is not the same as Hagoromo's, and Momoshiki and Urashiki most likely have rikudou chakara (as evidenced by rinnegan), yet theirs is not bijuu chakara or Hagoromo's chakara either.
What is my point here? Rikudou chakara is its own thing, so please do not make the argument "Hagoromo and Hamura were Kaguya's kids and Kaguya is the juubi, so they naturally inherited bijuu (juubi) chakara, and that is why they had rikudou senjutsu without being jinchuuriki". They did not inherit bijuu chakara from Kaguya. They inherited rikudou chakara! They are not the same thing!

One more thing: In this thread, I will refer to rikudou senjutsu and RSM (six paths sage mode) as two different things. You will see why later.
Now without further ado, let's get into the break down:
1. For starters, we know that Kaguya's power is essentially that of Earth's shinju. By eating that chakara fruit, she obtained the rinnesharingan and several other kekkei morra, as well as extremely powerful chakara. When she merged with the shinju, she became the juubi. We also know that Kaguya possessed the byakugan.
(Here is where the more theoretical parts start)
2. Hagoromo did not inherit Kaguya's byakugan trait. However, he did inherit a diluted version of her rinnesharingan, which became the rinnegan. Furthermore, he inherited his own unique diluted brand of rikudou chakara, which is diluted from Kaguya's chakara.

Furthermore, he also inherited his own unique brand of rikudou chakara that is also a dilution of Kaguya's chakara, but Hamura's brand is different from Hagoromo's.

It has to be Hamura's diluted brand). Hamura's chakara may not cause this evolution in all byakugan eyes as seen by the fact that Hinata received Hamura's chakara, yet no tenseigan. Of course, it technically isn't too late for Hinata to awaken it since Hamura himself was implied to have awakened it later in life, so for all we know, the same could happen to Hinata (though I doubt it will).

Anyway, now we can move on with the break down.
5. Hagoromo had Indra and Asura some time after he had already become the juubi jinchuuriki. Now let's start with Indra since he is the easier one. We all know that Indra inherited the sharingan. Now the source of his sharingan is kind of debatable. I can think of 4 possible reasons as to why Indra inherited the sharingan, and I will get into them in this spoiler tag.
1. Indra may have inherited it as a diluted form of Hagoromo's rinnegan. Dissenters to this notion argue that the rinnegan is an entirely separate dojutsu from the sharingan, as it can be awakened separately from the sharingan as evidenced by Momoshiki and Urashiki. I actually have a theory behind this whole concept that I will get into in a later thread.
2. Indra may have been influenced upon conception by the juubi inside of Hagoromo. We have seen that it is possible for a baby to be influenced on a genetic level by the fact that one of its parents is a jinchuuriki. This is seen by the fact that Naruto has whiskers. We know that whenever this happens, the baby is actually affected on a genetic level, as seen by the fact that Naruto actually passed the whisker trait down to both Boruto and Himawari (though I supposed that it is worth noting that Naruto himself is also a jinchuuriki, so Boruto and Himawari could have been influenced directly by Kurama). Having said that, it is possible that Indra inherited a very diluted version of the rinnesharingan due to the juubi being inside of Hagoromo. This diluted version would go on to become what we know as the standard sharingan.
3. Indra may have inherited the sharingan gene (a diluted version) from Kaguya (rather than the juubi). As we know, traits can skip a generation. A child can inherit a gene from a parent and be a carrier of it, but not manifest the trait, but still pass the gene down onto a child that does manifest the trait. That could be the case here with Kaguya, Hagoromo, Indra and the sharingan. Hagoromo could have inherited the gene for a diluted version of Kaguya's rinnesharingan (the standard sharingan), but instead he manifested the rinnegan, but was still able to pass on the sharingan aspect of the gene to Indra, who did manifest it.
4. This is the simplest explanation for why Indra had sharingan. However, it is least accepted since most people here are manga purists who hate filler, but... Perhaps Hagoromo simply had sharingan (dun dun dun)!!!!!!

Instead of inheriting the eye power of the juubi, I am proposing that Asura inherited dormant residual juubi chakara (which is the mixture of all 9 bijuus' chakaras).

This implies that Hagoromo also gave Asura a powerup in the same way that he did for Naruto and Sasuke.
Having Asura's RSM be juubi chakara + Hagoromo's chakara would go perfectly with that sequence of statements.
So that's my theory in a nutshell about rikudou senjutsu vs RSM.
Rikudou Senjutsu = Rikudou Chakara + Senjutsu
RSM = Rikudou chakara (or Hagoromo's specifically) + juubi chakara (or chakara of all 9 bijuus)
Now it should be noted that RSM is a derivation of rikudou senjutsu (since juubi chakara seems to automatically give you senjutsu as well, as seen when Madara and Obito became the juubi jinchuuriki). However, rikudou senjutsu does not necessarily imply RSM. Think of it like this: All thumbs are fingers, but not all fingers are thumbs. It's like that, but replace thumbs with RSM, and fingers with rikudou senjutsu. Therefore, when Madara made the statement "Naruto awakened the senjutsu of the six paths, Sasuke awakened the rinnegan, I have both of those powers", he was still accurate.
Now you may be wondering about some things like:
Rikudou Madara possessed juubi chakara + Hagoromo's chakara. Why was his mode not the same as Naruto and Asura's.
My answer: The mazou. Even though Naruto and Asura (according to this theory) possessed juubi chakara, they were not actually the juubi jinchuuriki and did not possess the mazou. We know that the mazou possessed its own chakara, as seen by the fact that old Madara was able to keep himself alive by tethering himself to the mazou and living off of its chakara. In fact, it is the sheer life force of the mazou that keeps a juubi jinchuuriki alive after the tailed beasts are extracted. It is clear then, that the mazou has some power and influence. This is what makes it feasible that actually being the juubi jinchuuriki (mazou and all) grants a different form from Naruto's and Asura's RSM. However, Madara and Obito's form can still be considered as like an advanced form of RSM since they do have Hagoromo's chakara + the juubi's chakara.

This shows that jinchuuriki forms don't just amp up and use the bijuu's chakara. They also amp up the individual's own chakara as well. This is also highlighted by the fact that when a jinchuuriki goes bijuu mode, they meld their chakara with the bijuu's chakara, and both chakaras become stronger as a result. Having said that, when Madara became the juuubi jinchuuriki, the traces of Hagoromo's chakara that he had would have amped up to be a significant amount. Also, this would have been the case with Obito as well. You may be wondering, "Where did Obito get any traces of Hagoromo's chakara?". Well, Obito at the time had Madara's rinnegan which contains Hagoromo's chakara.
Now, you may also be wondering, "What has Naruto been using all this time?".
Well:
In the war he only used RSM.
As an adult, he uses rikudou senjutsu. That is why his mode lacks the pigmentation despite using senjutsu. Now you may say that we've seen the Last Naruto and adult Naruto (while not using Kurama's chakara) use regular toad SM (with the pigmentation). Yes, that is true. Naruto never lost access to toad sage mode just because he gained rikudou chakara. Naruto and Sasuke can choose to use or not use rikudou chakara in their jutsus (as seen by the fact that we saw Sasuke willingly make his chidori black, while we've also seen the same Sasuke use normal chidori). That is why Naruto can still use base toad SM and BSM with pigmentation. He doesn't have to add his rikudou chakara to the mix.
Now, before you say, "Rikudou Senjutsu has the rinnegan symbol on the back and 9 tomoe", remember that Naruto, Madara, and Obito were using not just rikudou senjutsu, but RSM when they had those symbols on the back. As for Hagoromo and Hamura, those rikudou cloaks were actually just their base clothing. They wore those cloaks casually even when not using any power whatsoever. In fact, even Indra and Asura wore those cloaks (and Indra never used rikudou senjutsu or RSM).
You may also say that Naruto used RSM without the cloak and the rinnegan symbol and all when he kicked Madara's truth seeking ball. Well remember that Naruto can display that he is using a small amount of bijuu power (without going into any cloak) via a small change in the eyes. He has even shown this with Kurama.
Remember this:

These were examples of Naruto tapping into Kurama's power and displaying it via the eyes without going into a cloak. If he can do that with Kurama's chakara, then why not all 9 bijuus chakara? That would explain his "base RSM" when he kicked Madara's truth seeking ball.
If you say that Naruto's skin doesn't glow for RSM, you're right. Like I said though, he hasn't used RSM as an adult. He has been using Rikudou Senjutsu as an adult, which doesn't actually change one's appearance as evidenced by Hagoromo and Hamura just being in their base clothing and no special cloaks upon using it. (Once again, I remind everyone that Madara and Obito's forms were also advanced RSM due to the presence of the mazou, in addition to being rikudou senjutsu since RSM is a derivation of rikudou senjutsu). Therefore, Naruto can use Kurama's power with the rikudou senjutsu if he wants to and have his skin still glow even though he is using rikudou senjutsu.
As for the truth seeking balls, adult Naruto should technically be able to produce those even in his base looking form (using rikudou senjutsu though). After all, Hagoromo and Hamura produced truth seeking balls in their base looking forms (rikudou cloaks are their base clothing).
Anyway, that is my theory break down in a nutshell.
Hope you enjoyed. Discuss.
