I think some dojutsu are meant to be single eyed and not a pair. Madara calls Sasuke's Tomoe Rinnegan the "One-eyed Rinnegan"

Pretty sure he just describing it being only in one eye

I'm not sure how it was said in the literal text, but in the official translation it is not just "the Rinnegan in one eye" but "One-eyed Rinnegan" which is more akin to him naming it that instead of just describing it.

I dont think any of these abilities are attributed to the RinneSharingan. The only ability shown exclusive to it is the Infinite Tsukuyomi

Or blue. Or gold.

This isnt a Rinnegan ability

Mmmm only Tomoe Rinnegan. For Sasuke its a sign that he has his Sharingan/MS active at the same time. Not sure what it means for Urashiki

RinneSharingan has a few exclusive techniques

• Infinite Tsukuyomi
• Amenominaka

Its a hard stretch to say he is naming it rather than describing it.

since yomotsu hirasaka has only been used by rinnegan users and urashiki's rinnegan was the source of his i will count it as a rinnegan ability. and yes i know sasukes rinnegan is essentially his mangekyo as well,because his is literally a rinne-sharingan in every way besides name. since every rinnegan comes with unique abilities kaguya's infinite tsukuyomi and amenominaka can easily make sense as just unique to her eye alone and not just a rinne-sharingan thing,after all we have seen the regular make portals and travel through time.

We have seen Rinnegan open portals, not transport multiple people intantly to a new dimension and nothing close to the likes of the Infinite Tsukuyomi has been used with it Rinnegan

Sasuke's Rinnegan is not the same as the RinneSharingan because the series has made a point to differentiate them and RinneSharingan has abilities on a much larger scale than Sasuke's Rinnegan-Sharingan

Simple explanation. Rinne Sharingan is a parent to both Sharingan and Rinnegan. Kekkei Mora simply means, the progenitor/original ability.

Like Kaguya's Ash Bones are KKM and Kimimaro's bones are a KKG, diluted version of it. Therefore in the Sharingan-Rinnegan family, Rinne Sharingan is the highest one can get.

There are people who have both the Sharingan and Rinnegan:

• Madara had to switch between the two and couldn't have both active at the same time
• Sasuke can have both active at the same time unlike Madara, but has only 1 Rinnegan (most likely because a pair is more powerful, as not to make him too overpowered)
• Urashiki for all we know, might have had the Sharingan as well, explaining the tomoe and is just like Sasuke, but has 2 Rinnegan, making him technically superior

Now, having powers of both the Sharingan and Rinnegan and even being able to use them at the same time, STILL isn't the same as having the Kekkei Mora Rinne Sharingan, I'd say it's a close 'recreation' so to speak, but still inferior.

the rinne-sharingan is sort of like the parent of both since they got the powers from ten tail tree fruits and all ten tails possess rinne-sharingan. kaguya's manifestation just seems to be the most genetically complete out all examples we have seen. currently there is no evidence of sharingan/mangekyo being present in the otsutsuki clan outside of the tomoe rinnegan though we atleast know from kaguya that amaterasu was likely seen in their clan.

The rinnesharigan is manifested when the god tree is eaten hence the sharingan being the first dojutsu known to earth. The rinnesharingan has no connection with the rinnegan or sharingan infact it is just looks as jigens juubi seemed to posses one edit: im a idiot lol

the rinne sharingan could likely be an evolution to rinnegan since otsutsuki eat many fruits gaining more and more powers. since kaguya and isshiki are much more powerful than the others we have seen they have likely eaten many more fruits and have evolved more powerful dojutsu.
