The reason for that is a little more complicated. Luckily, you're talking to someone whose assignment it is to research and collect data about all this.
[Since he's giving a full on lesson he'll just doodle on a piece of paper and hold it up.]
Now, instead of a wavelength, try to think about the world around you in a more physical way. Like this is one big dig site, and you're drilling down to take a core sample. [This really does look like a geology diagram.] You have the normal mundane stuff, like the big lake and the architecture and other fixtures of the normal city. The supernatural things that are a part of daily life here, those are another layer. And beneath that, there's a whole other layer that even people who live with the supernatural might not be aware of. This is Kaisou's Spirit Vein, and it marks the barrier between Kaisou and other worlds entirely.
If you look up at the sky at night, you should see something resembling aurora borealis. That's what the Spirit Vein does to the sky when it's particularly strong or active, and Kaisou's is both.
A while ago, there was someone with... ill intent... who tried to punch through the veil between worlds. He damaged it in such a way that the Spirit Realm—which is on the other side of that—has been leaking into our world. Suddenly becoming aware of the supernatural, gaining powers and features you didn't have before, visitors from other worlds, gates to the Spirit Realm appearing with alarming frequency... these are all symptoms of that.
To be clear, Spirit Gates leading to other places have been a part of our history for a long time, and they feature prominently in many mythologies and legends. But it usually isn't like this. That's part of why me and my colleagues, including... it looks like you know Abasi? That's part of why we're here.
I'm Mikleo, by the way. Officially I'm Assistant Wisteria, but just Mikleo is fine.
