Nakano Broadway
The Nakano Broadway, a iconic landmark in the Nakano district of Tokyo was for the most part surprisingly absent, having been closed for 'Routine Cleaning' meaning the only people present in the building would likely be a skeleton crew of workers. There was also a homeless man sleeping in a nearby allyway, as well as a passed out man on a bench on the opposite street. Likely from a night of drinking.
A decent stroke of luck for the two masters and their servants. But also a rather spot of bad luck potentially for the workers inside. Given that they would be for the most part going to get added to the list of mysterious deaths in the Tokyo Metropolis area. In such a beloved place no less. Simple scouting would give this much at least.
However without even scouting, the mere proximity to the Broadway would feel slightly sickening for mages possessing magic circuits. A unknown headache inducing pressure. As if the very molecules in the air were saturated with something thick and viscous. This same pressure would also be felt by the servants due to them being beings formed from magic. However those with no such Magical circuits could not even detect this 'gas-like' saturation of something. Which would mean that a normal human would have no warning that something was wrong.
It would start to become obvious with the passing time that whomever had called you here wasn't outside the building, and you'd have to get inside to even get a better bearing of what was going on. Of course how you'd both enter is up to you... or Even what you'd do when you feel each other nearby.
Sukiyabashi Crossing
Sukiyabashi Crossing, A scramble crossing not uncommon in Tokyo. Though much less populated then during its day-life and slightly less then normal amount of people enjoying the tokyo night life due to the recent news. There was still people walking about. Unaffected by the strange instance in the center of the crossing. Vehicles were not driving at hours this late. Because if they were they might sink in what appeared to be a visible distortion in reality. Visible only to servants and masters that possessed magical circuits. The Distortion took the form of a 'refraction' of light. The area behind the distortion appeared well 'distorted' from all angles viewed it seemed like a singularity of space. Seeping out from this 'distortion' was trace amounts of water vapor that quickly disappeared indicating they came from a more magical origin.
The Night-life ignorance and self-distractions would mean that nobody would really be noticing nore attempt to step towards the centre of the road. Less of course you were but a curious master. Though with both of you approaching this meeting location. Would you be meeting up on good terms, or would you consider the others presence to be an ambush...
Still then as you'd get closer to the distortion. That magical 'heaviness' in the air would be felt, and the headaches for mages and servants alike would worsen the closer you got to the point of distortion. But where on earth was the person you were supposed to meet?
