When did she created a soul?
She doesn't need to. She could put existing souls in there.
Only in the same sense as the help from the future. I.e. a Bootstrap paradox.
1 - it is necessary to review her profile on the wiki since time travel is included as a Standard Tactics not as a passive ability.
Fair enough. I can do that.
2 - you still don't answer about the fact that Hajime can possess, control or steal Qiqi's technology even if the version of her comes from the future, Hajime could already use time travel like her analyzing her version of the present.
He has no time to analyze or possess anything. Qiqi can use her future development to boost her speed to the point that she blitzes. To that comes that he doesn't have prior knowledge.
3 - you said: In fact, it is likely that in the future Qiqi will have the technology necessary to create robots with souls, if she wants to.
If we are going to use "it is probable" then we could say that Hajime would have the ability to travel in time before the battle, as he creates artifacts often based solely on works of fiction, (so we have to be sure if he has a soul or not and if she can create souls)
I think the cases are a little different here.
There is significant evidence that future Qiqi has such tech. The only question is if the word "soul" is used literally.
That's far different from speculation that Hajime might have constructed a device he hasn't shown before the battle started, when he had no need for said device.
4 - it has already been mentioned, but Hajime can also walk away from the fight and leave his golems fighting for him so he can "prepare" for combat through time manipulation, so at this point there is really no difference between the two.
Qiqi can follow him wherever he goes. Also, again, future her can blitz, so he has no time to do anything or even decide that he wants to do that.
5 - Hajime's possessed golems are not "allies", they are servants, in addition to being possessed by golems with his permission and which can be destroyed whenever he wants, so I don't see how Qiqi invoking allies is fair (since if that were the case, he would be enough summon Endou and she would probably lose since while she's staring at Hajime she probably wouldn't be able to notice Endou)
Allies as equip are always an edge case, however, SBA does consider humans present and in principle allows for their use.
So while one can argue that Qiqi may not grab a specific human, she is certainly allowed to use some humans.
6 - My Opinion: if the two can stay away from the fight to prepare better and I think this fight will last forever unless they call on allies
Well, I don't think Hajime can stay away from Qiqi.
The miniature guarden is disconnected from the nine realms, this is the reason Tio wasn't influenced by the DRAGON while he was able to influence dragons in another universe.
She needs multiversal range to reach it.
Surely you mean interdimensional range, as Hajime himeself doesn't have multiversal range.
That aside, I don't know what DRAGON is or why it would prove that Qiqi with her transfer technology that works beyond spacetime wouldn't be able to reach it.
And then there's the option of tech improvement.
What prevent Hajime from creating Time traveling Grim Reapers?
That the moment the fight starts a future Qiqi fast enough to blitz him appears, costing him the chance to do anything that requires any time to do.
It detect anomalies, unnatural alterations, and nullify said alterations, how you may ask? simple, with evolution magic which view and manipulate information itself, that way it can know everything and filter just that.
What Qiqi does is not an unnatural alteration, though.
But even under your argument that the artifact wouldn't automatically work on techno stuff he can literally just change that in an instant the moment the fight start as he can evidently see her Qiqi use techno, his info analysis would instantly tell him it is indeed techno stuff, and he can just use his transmutation to change the artifact to also target techno.
Is that something he is shown to be able to do? How would he separate between technology and not technology? Could he even analyze what Qiqi is doing in an instant?
Also, future Qiqi is faster, so before he does that he's toast.
You are assuming that a version from a different time period wouldn't have any effect in time itself and also assume that the fundamental information itself of Qiqi wouldn't show that she is from a different time period, additionally you are also assuming that she or her weapons wouldn't appear near him the instant the battle begin to kill him the fastest possible way.
An effect? Yes. But a natural one. If you say that Hajime could make something erase anything that fulfills arbitrary criteria like "anything that ever ate bread before" than I want proof of that.
What the "appear near him" is concerned: If she can't win by doing that, it wouldn't happen, due to the nature of time travel. Again, time travel is forced to be non-paradoxical (bootstrap paradox aside). A future version of Qiqi that can't exist, because Qiqi gets killed and never becomes her, can never appear. Hence the future version of Qiqi that just instantly gets erased can't exist in the first place.
Suppose the talisman really doesn't allow future Qiqi to spawn near him. In that case, she will spawn further away from him, because those potential future versions that do that are the only ones that can exist without causing a grandfather paradox.
I'm bring it up to argue that he can indeed interact with time travel with restoration magic, because restoration magic affect the very time itself and its laws, so he is able to affect the very time paradox itself and likely even get his own.
I have no idea what that is supposed to mean in practice.
I doubt he can replicate Qiqi's technique using his own magic, if that's what you mean. That's just kinda beyond it's shown applications and just because Qiqi can do it that won't automatically change. I mean, as said, even a character that would steal Qiqi's time machine if her futue self didn't interfere didn't get it.
Because you haven't show at all any proof of Qiqi or her verse having technology able to affect the souls, neither the profile mention something remotely close to that, so as that's the case I'm going under the conventions established in Arifureta that state that you need spirit magic to give an inanimate thing a soul. Also, you are using a
nominal fallacy to assume that robot Qiqi have a soul due to the naming of the process with which her consciouness was transferred, instead of the more normal and logical assumption that the data from her brain was gathered and transfered to a robot to create an artificial personality equal to her. If that naming process was valid then all the AI in Arifureta, including the ones from the world with no magic at all and that were created purely through normal technology, would have a soul due to possess personalities and emotions, this despite the soul being something actually concrete and specific in verse that they wouldn't have a way to get, heck even
Apostles who were created through magic and possessed personalities explicitly didn't have a soul (because spirit magic wasn't used to grant them a soul).
See the scans I posted above.
And about using someone else, she wouldn't be able to use those from her world as they don't possess the unique energy will power (as they are from a different Earth than Hajime and are more like the habitants of the Factory World) that let them use any other type of unique energy (and thus any other energy system), she would need to use someone from either Hell, Earth or Tortus for that, but those from Hell are disqualified as they are closer to abstract beings and all of the sentient ones follow Hajime (his personal army of Grim Reapers is made from the most elites demons from Hell who are possessing his artifacts), so she would have to people from Earth or Tortus, but then she would need to face the problem of getting her hands in the artifacts that grant ancient magic but those are in possession of Hajime and she can't use the ones from the past because Hajime was very explicitly the first person to ever have ancient magic granted from most of them (something actually very important from the story, so she can't change that past as you said with Qiqi time travel outside of time paradox), but if she someone get her hands on said artifacts she then also would need to use a person with a strong enough soul to withstand the impact from learning ancient magic, her other option could be use natural ancient magic users but in that case she would need to use a lot of cross-breeding human experimentation (which doesn't sound honestly like something she would do with how good of a person she is) until she could get someone with ancient magic (complete ancient magic instead of just partial ancient magic like 99% of Atavist, who by themselve are already extremely rare) but with that method she would need to use various ancient magic users as natural ancient magic users are only able to use a single type of ancient magic user. And on top of all the previous things those persons would need to somehow overcome the busted fear hax of Hajime to not die, get paralyzed, have their bodily functions stopped or lose all thei SAN value against him, and they would need to be amazing enough to face in general all the stuff from Hajime.
Wasn't Hajime himself a human from Earth?
I will say that advanced genetic manipulation technology exists in the verse, so whatever crossbreeding you bring up is not that out of question.
The moment the fight start future Qiqi need to instantly appear, far away from Hajime to not be inside the range of the Guardian Talisman time nullification, and then instantly kill Hajime to not give him any sort of time to do anything: neither analyze her stuff, copy her technology or get a hold of it, create counters through artifacts, use concept magic, directly use his transmutation on Qiqi or anything she have to control and do whatever he desire with them, or even retreat to his pocket world the instant his body feel any incoming danger (because his body can take defensive options before he even think); then on top of that she would need him in a way that somehow he doesn't get resurrected by his time manipulation artifact inside his pocket world; she would also need to somehow deal with the army of abstract beings that follow Hajime in a way that prevent them from both protecting him and attacking her (including obviously the supernatural possession).
For Qiqi to win one would need to make a lot of assumptions and essentially write a fanfic, instead of just going with Hajime who have far more viables, realistic and likely options and ways to win, so at that point one may as well argue that Qiqi can defeat anything and everything. My vote if it wasn't clear go to Hajime btw.
I don't think those "assumptions" are assumptions at all.
The final boss of Qiqi's manga could blitz her, so we know Qiqi can upgrade her tech to those levels. That's not speculation, she definitely can just make herself fast enough to blitz. And it is not further out of character for her to do that.
And that alone basically eliminates most else.
She can just drag him to the past or future to separate him from any allies and equip he might have before he reacts. Or set up things to destroy the device in the right moment, like she did with the back-up devices of Ka'more.
And so on. One thing you don't seem to take into account is that only a successful future version can appear. I.e. her future versions in practice are filtered to have the right strategy. The only way Hajime can win this is essentially if Qiqi, with prior knowledge and prep, could
never win. No matter the scenario. It's like fighting people who know all possible futures, in the sense that only if no winning future exists, you win.
I find it far more assumptive that there is absolutely no way for her to ever win, given the outlined conditions.
