> Mitakihara.
Okay, on second thought, you... honestly don't know why you're even considering Kamihama. You've only ever heard of the place in passing, don't have a clue what the city is like, and you're not even entirely sure where it is. In the same vein, you know basically nothing about Hohzuki, meaning you'd be heading into completely unknown territory and hedging your bets against an unknown number of magical girls. You'd very much prefer to avoid that, and since you're definitely not going back to Sengeitsu, that narrows your options down to three: Asunaro, Kazamino, and Mitakihara.
As it happens, those are the three closest cities to Sengeitsu, and also the ones you actually know something about the magical affairs of, thanks to being curious enough to ask Kyubey about them back before he started stonewalling you. While you no longer trust the little rat much further than you can throw him (which is now nowhere, seeing as how that would be difficult without ARMS), you don't recall him ever actually lying to you outright, so you don't doubt the information he gave you was at least technically correct. Hopefully, that should make this choice a little easier.
Asunaro... it would be convenient, seeing as it's the nearest of the three, but given what you've been told about it, perhaps that's not the best idea. According to Kyubey, Asunaro is home to a frankly ridiculous number of magical girls, including a long-standing seven girl team thereof. So far as you're aware, team ups in general are relatively rare in your former line of work, not just because of competition for limited resources, but because most "teams" don't tend to last very long. For one to manage to keep seven people alive and functional long enough that Kyubey actually took notice, either their strength or their teamwork must be utterly absurd. As such, you imagine heading into Asunaro might be something akin to deliberately leaping directly in front of a firing squad, so- yeah, you think you'll be crossing that one off the list.
Kazamino... Kyubey didn't have much to say about that one, to be honest. He basically just told you there's nothing all that notable about it, and that in terms of its magic situation, it's fairly average. Unfortunately, this was before you learned how good Kyubey is at twisting his words to imply meanings completely separate from what he actually says — his definition of "notable" may be very different from yours, and you never got clarification on what "average" specifically meant either. Presumably Kazamino has less magical girls than Asunaro at least, since the latter most definitely is not average by his metrics, but that still means you have functionally zero clue what to expect from the city, which is practically begging for disaster. It could be perfectly fine, maybe even your best option, but you're not entirely sure you're willing to risk it.
Finally, Mitakihara. Apparently, the place is pretty much controlled by a single magical girl who has essentially the entire municipality under her jurisdiction, and whom Kyubey managed to sound almost fond of, despite his self-purported total lack of emotion. While Mitakihara is relatively small as cities go, to the point that it's interchangeably known as Mitakihara Town, if territory for magical girls is as contested as you've been led to believe, you think you can assume that the noted girl is really good at what she does. Probably even more so than the Asunaro group, in fact.
That being said... if your general approach to magical girls is just going to be "don't approach", then the city with only one of them might make more sense to go than anywhere else, regardless of how powerful she is. A single girl cannot possibly be hunting witches at every waking moment, nor should she be able to reliably patrol the city in its entirety within the span of a day. Mitakihara may be relatively small, but it's still a city, so total coverage seems like it would be impossible short of some sort of teleportation power. Even if she did find you, you could always just shove yourself into the sky again, and unless she can fly you'd be totally safe... granted, you have no clue what her powers are beyond the type of weapon Kyubey says she uses, and you literally just encountered someone with something pretty dang close to flight, but magical girl powers vary heavily enough that that would be a risk no matter where you go.
Yeah, in the end, that seems like your best option. Mitakihara it is.
...now, how does one get there, again?
It takes you a little while, but thankfully you do still know at least generally which direction one needs to leave Sengeitsu in order to get to Mitakihara, and your ability to go upwards seemingly without limit does eventually allow you to pinpoint it. At least, you think it's Mitakihara you're looking at now, unless there's some other nearby city with a port on one end, a river running through it, and a building with a spire so high that it's noticeable even from a couple miles up.
Actually, given that last one, it's definitely Mitakihara. Nowhere else around here has architecture anywhere even near that ostentatious.
Moving at a slight diagonal, you push your barrier forward towards the distant city. Easier than going back down since you can keep the city in sight, and hey, the quickest path is a straight line and all that.
...unfortunately, it may be a straight line, but it's not a particularly short one, and your barrier does not seem to move any faster going downwards than it does going upwards. This could take a while. It doesn't seem to take much effort or concentration to just keep pushing yourself forward though — maybe you can do something else in the meantime?
[-] Exit?
[-] Leave?
[-] Vacate?
[-] Egress?
[-] Seriously, go! There's only so many ways to rephrase it, so stop getting distracted and go take a look at the outer layer of your barrier already!
