My Interpertation On Soulmates - An Aiura Analysis and Saiura analysis dissection.
Okay so as we know, Aiura herself is not truly aware on the way soulmates exactly work as it's a blurred line for her and is necessarily stated as more of a desire, most soulmates canonically do not always meet in the saiki k universe. Aiura herself takes the initiative to find her soulmate for her desires, I believe that she thinks soulmates reflect your desires and are the person to understand you the most, so she attempts to advance Saiki into sexual and romantical relationships by that, (remember this point moving forward.) she seems to fully be aware that Soulmates is not a guarantee that they'll be your fated partner as she doesn't refer to other people's fated partners as soulmates when she's doing readings. There are definitely different types of soulmates that will determine their FORTUNATE or UNFORTUNATE fates and circumstances with you - this is how ill categorize the types under two categories. What are Saiki and Aiura then? I believe they are actually in the fortunate section- they do affect eachothers *soul* fortunately through fate because of Saiki's circumstances, Aiura was there to help and be able to achieve what Saiki's wanted fortunately.
One of the ways I see soulmates is that their main pointers and integral effects is that soulmates are - "mission for eachother/together" and I actually completely agree with that too, soulmates is a broad concept that can fit into anything, good or the bad. There's this other media im in where these characters are connected to be soulmates but the other is extremely toxic and abusive. So soulmates in their concept doesn't mean good, that they're just connected by souls fortunate or unfortunate. That would make sense for Saiki and Aiura, and fits more as shown that he needed her, because his future wouldn't have changed if not for Aiura..? In his case, being somewhat fortunate. That's why I categorize them as fortunate, relationships are up to fate and is matters on how you treat your soulmate. There is also different compatabilities to consider so soulmates matters in the circumstances that are set, some don't NEED to meet their soulmate for their future but Saiki and Aiura did as his future changed expetenciously. Aiura uses her powers in good fate with the presenting of Saiki, gaining her a new perspective ahead. This was fortunate and affective for both.
Aiura and Saiki's souls comply with eachother, I think that they're soulmates where it's not about romance or platonic but they're souls are connected, their powers comply with one another just like their souls. That's exactly what has been shown. This doesn't guarantee their platonic or romantic bond will be strong as this is up to fate! As heavily shown.
My interpertation on Aiura's character with Saiki:
Aiura is a very cool and unique character, to which her emotions may not immediately clash with Saiki's because they have different views on how to treat certain situations (example: Mera and her Dad), which makes a compelling perspective/POTENTIAL in their relationship to where Aiura may try to give Saiki a push on how to approach things just as Saiki does with her. Although, sadly, their relationship did not progress/develop as much as it should have. So this is only potentials and slight slight progressions.
But I feel that her flaws exaggerate more expetenciously/horrendously when she's with Saiki, which isn't a good thing. That's why I'm always surprised to see people prefer Aiura when it comes to choosing who's great with Saiki, when you realize how she was harassing him about her desires and her assuming he'd like them too, and she even goes to thinks he's a sadistic, she only thinks this just so she could like the idea of him being her soulmate because she found him very boring.
Desires in this context are about advancing into romantical/sexual relationship, and those are Aiura's Desires.
Aiura is a very sexual person who has tried putting these Desires onto Saiki because she believes soulmates reflect your desire and that he would genuinely enjoy that to which he wouldn't, which shows her very flawed perspective on Saiki and shows this flaw, crossing boundaries. Because of the many times she has harassed them in interest to advance their relationship to more romantical/sexual, she has crossed many boundaries set by Saiki, so far that she has used her own divine powers to intervene within Saiki's life after he purposely avoids her, she then tries to plan a "lucky feel" moment.
(EXPLANATION: a lucky feel moment is when two people get into a suggestive accident, both parties not knowing of this suggestive, mainly sexual - feel, contact on contact moment, hence the name a lucky * feel * moment.)
But this wasn't the case here, since Aiura was aware of what would happen and she was planning this while using her divine powers to intervene and pass it off as an accident to Saiki. (See Chapter 186 to understand)
This is one of an example of her flaws on how she selfishly used her powers to cross Saiki's boundaries and reflect her desires onto Saiki. She doesn't seem to usually do this with anyone but once she is with Saiki, all of her flaws are heavily exaggerated and worsen within.
She has made assumptions onto Saiki, calling HIM selfish because he seemed unkind to her, a negative moment she had on Saiki's character, to which, she doesn't seem to do with everyone else either. Which adds to the list of flaws shes shown expetenciously with Saiki.
Sometimes, it seems like Aiura doesn't take to consider Saiki's best interests at times only because she misunderstanding him and does not have a great perspective on who Saiki truly is, her ideas and assumptions blind her to connect with Saiki any further, which is another flaw that gets emphasized when shes around Saiki.
I believe Aiura is a kind and usually selfless person, but as I said, when she is with Saiki, her flaws end up exaggerating and heavily will overshadow her positive aspects and traits.
The way she views soulmates is inherently a stubborn and selfish way, as she's not able to think more above her horizon other than her advancing her relationships romantical and sexual with Saiki, not realizing she has already made a strong bond within their powers and friendship. <-THIS is what soulmates is for her and Saiki. She gravely misunderstands that and blinds her from advancing a better bond platonically with Saiki unless it's within/about her powers, though she tries to use them negatively and intervene divinely - AGAINST saiki, unfortunate act but this wouldn't count towards the unfortunate category since this was just her misusing her powers.
In conclusion: Saiki and Aiura are soulmates, in the sense their souls comply with one another within their powers, it's not romantical or platonical but its so their future can move forward, so that their SOULS are able to move forward, they're connected divinely FORTUNATELY
It's good that she found him even though in mind she had it as a stubborn desire, it moved into something else giving her a new perspective positively and fortunately from Saiki, just as she, Aiura, does with Saiki.
Does this mean Saiki has to stick with Aiura forever? No
Does Aiura have to stick with Saiki forever? Also, No
Is it anywhere implied that their compatability/soulmates is inherently tied to love? No ^^ that's all! That's something fate will do. It's not a guarantee!
I do wish this was more elaborated within the soulmate connection, but to me—this is the one that makes the most sense and aligns with canon while considering the actions and placements in mind of Saiki and Aiura's relationships, they are different than normal people who are not psychics, thus they'll have a different connection in mind but they still have the same goal as most non-psychic soulmates do - for their futures to move forward.
