In this post I will theorize the arrival of Kaguya and Isshiki on Earth, the betrayal of Kaguya, Ten-Tails, the Shinju and the Otsutsukis with elements from both Naruto and Boruto!
Important note: I will also take into consideration the Naruto Shippuden Anime.
First of all, let's start at the beginning, Kaguya and Isshiki land on Earth together and plant a Shinju, Amado confirms it and Kaguya's flashback in Naruto Shippuden too (since there is a planted Shinju and Kaguya was on its tracks)
In Naruto Shippuden we could see the Shinju crashing on Earth in the form of a meteorite and this is indeed how they plant it on a planet
What makes me say that? The other Shinju we saw in Boruto:
- The Shinju present on the planet where Momoshiki and Kinshiki took Naruto to remove the Nine-Tails from him
- The many Shinju that we could see in episode 15 of Boruto
A common point between all these Shinju is the hole formed by the impact which is always present, which can therefore confirm that a Shinju is created by crashing on the planet in the form of a meteorite as in the flashback by Kaguya (Naruto Shippūden)
Now, regarding Kaguya and Isshiki's arrival on Earth, I will theorize what happened and how they did it
Thanks to Amado we know that the Otsutsuki travel in pairs mainly for this story of Ten-Tails/Shinju
In an Otsutsuki duet, it is the one who is of lower rank who must be eaten by Ten-Tails to give birth to the Shinju, the one who is sacrificed prepares a receptacle to place a Karma on them and thus resurrect after being eaten by the Ten-Tails
For the Kaguya and Isshiki duo, it was confirmed by Amado that Kaguya is inferior to Isshiki (we can also see it thanks to the stelae) and it is therefore she who must be eaten by the Ten-Tails to give birth to the Shinju
However, Amado contradicts himself, in chapter 46 he says that Kaguya and Isshiki planted a Shinju and that's only after Kaguya opposes him (for the fruit or another thing) but in chapter 51 he says she "had to 'sacrificed herself so he's implying she didn't
Amado says a lot of things but we can't believe him on everything 100%, the only ones who can tell us the whole truth are Kaguya and Isshiki, the only thing we know about Amado is that he wanted to revive his daughter Akebi, so he may very well modify some information for his own interest
Now I will tell you how I think Kaguya and Isshiki's arrival and Kaguya's betrayal played out chronologically
Kaguya and Isshiki land on Earth (Kaguya must have had her betrayal in mind from the beginning), so that Isshiki wouldn't suspect anything she had to do everything that normally had to be done, prepare her vessel to resurrect and be eaten by the Ten-Tails
She gets eaten by the Ten-Tails, the Ten-Tails is planted on Earth, it turns into Shinju, she comes back to life sometime later thanks to her receptacle
And it is at the moment of her resurrection that she betrays Isshiki by taking him OFF-GUARD (Please @NarutoShipp8 and @Bob74h2, don’t start a debate over this😭), he could not have expected it since she is part of his clan and she had done everything as planned
Image 1: Kaguya is eaten by the Ten-Tails and the tree is planted
Image 2: Kaguya goes to see the humans
Image 1: the tree is very small
Image 2: the tree is really very big
So, I think it was between this time interval that she betrayed Isshiki
furthermore, when she goes to see humans, she presents herself as "the one who protects the Divine Tree", the role that Isshiki had
And another thing that can prove that Kaguya did indeed resuscitate via the Karma and therefore that she was indeed eaten by the Ten-Tails to give birth to Shinju on Earth is this form of Kaguya, let me explain
In this form Kaguya no longer has her Otsutsuki clothes like those of Isshiki, nor her horns and I may have found why
The Karma
The Kama allows the Otsutsuki to make a replica of themselves and implant it into the receptacle's body, but the Otsutsuki may "regress" in form when it does (it may vary in quality depending in the receptacle used)
In chapter 35 when Sasuke discovers the steles, we can see that Kaguya is represented in the Otsutsuki dimension with her horns and her clothes resembling those of Isshiki
So, I think that when she landed on Earth with Isshiki she was in this form (horn and clothes) but after being eaten by the Ten-Tails and resuscitated thanks to the Karma she "demoted" in her form
And besides, when she decides to eat the fruit of the tree, she directly recovers her form with which she fed the Ten-Tails so that it turns into Shinju
And what's crazy is that's exactly what happened for Momoshiki with Boruto, since Kinshiki was inferior to him it was up to him to sacrifice himself to the Ten-Tails all the time
He landed on Earth with the same form present in the Otsutsuki dimension, which shows that this is his "base" form as an Otsutsuki
During his fight against Naruto, Sasuke, Boruto and the Kages he changed his lower duo (Kinshiki) into fruit and ate it, resulting in this transformation
But at the time of his defeat against Boruto he decides to put the Karma to him to be able to resuscitate later
And exactly like Kaguya he "retrogrades" in his form after putting his Kama on Boruto, no more rinnegan on his forehead, tiny horns, no more his black marks on his face and body
It's the same in the manga when Momoshiki announces a dark fate to Boruto, he has much smaller horns compared to his "base" form present in the Otsutsuki dimension but also the one with which he came on Earth
Image 1: Kaguya "base" form
Image 2: Momoshiki "base" form
Image 3: Kaguya after being revived via the Kama
Image 4: Momoshiki after putting his Kama on Boruto
Everything sticks, when an Otsutsuki uses the Kama it "retrogrades" to its "base" form
So, if my theory is correct the in Boruto explained why Kaguya had a different form (without horns, Otsutsuki clothes nor Rinne Sharingan on her forehead) during her flashback in Naruto Shippuden, she "demoted" after resurrecting through Kama
And we can also see it with Isshiki, his "base" form present in the Otsutsuki dimension has a slightly different and much longer horn compared to his horn when he resurrects via the Kama facing Kashin Koji (but less blatant than for others)
Besides, the moment he absorbs the Ten-Tails' chakra to go and retrieve Kawaki from Konoha, he undergoes a slight transformation and he has exactly the same horn as in the hologram, perhaps there is part of his power to its "base" form in the Ten-Tails
The moment he took full control over Jigen's body, he may have gone to retrieve his lower body from its "base" form that Kaguya ripped from him, to feed it to his Ten-Tails
What explains why Jigen (Isshiki) could take so much chakra from his Ten-Tails, is because his Ten-Tails has his lower body in the form of a "base" inside him that Kaguya ripped off, and saw that the lower part of his body was non-living, his Ten-Tails did not turn into Shinju
The only hole I found in this is that Shibai, the one from Amado gave DNA to Daemon and Ada (Daemon still weaker than Prime Isshiki @Dyss00😉), apparently became more powerful through resurecting several times with the Karma. However, the statement says that he "cheated death" and its not talking directly about power.
And that's all! What you all think?
