You decide to see what's going on outside.
Sliding the door open, you find Nitori and Marisa, along with a few people you don't recognize. There's a woman dressed in black and white with a camera around her neck trying to ask Nitori questions (and mostly being ignored); a girl wearing bunny ears, a white button-down shirt with a tie, and a blue skirt; and a woman with a very strange clothing consisting of quadrants of alternating red and blue with what looks like constellations, and on top of that, what looks like a nurse's cap, only blue with more constellations.
"Who is your first suspect?" The girl taking notes attempts to ask Marisa. "And why did you bring Miss Yagokoro here? Are you going to be looking into this as an incident?"
The witch ignores her.
Meanwhile, the strangely-dressed woman talks with Nitori.
"Yes, that is quite strange. I don't think I've ever heard of anything like that before."
"Yeah." Nitori responds. "From what I hear, the rest of it isn't that stange if we assume that it's Yukari-"
Everything turns white.
It takes a moment for the pain to sink in. When it does, the only way to describe it is pure and intense.
But it isn't just pain.
It's ironically easy to forget, perhaps because of the pain, but the pain isn't just sudden pain upon hearing a name. The pain comes from remembering something. It's like the memories are sealed deep inside. You could imagine that they were stored in a heavy steel vault. For them to suddenly be torn out without first unsealing the vault, it would need to be very violently pulled through the solid metal walls. While you're absolutely certain that this isn't how memory works at all, your intuition tells you that it's a pretty good model for what's going on.
...You're trying to force yourself to analyze this to distract yourself from the absolutely terrible pain that you're feeling. It helps a little bit, but it requires a lot of concentration. By this point, not only are you in pain, but the effort has left you mentally exhausted.
When your vision manages to blurily return, you find yourself on your hands and knees where you were previously standing.
(Well, that's a good sign.)
How the hell is that a good sign? It hurt like fucking hell.
(Yes, but you seemed to have recovered from it pretty well. It seems like the more it happens, the less painful it gets. Your analogy might be more accurate than you thought. If you pull objects through the solid wall of a vault forcefully, wouldn't that make it easier to get the next few objects through by pulling them through the same hole? Of course, they won't fit perfectly through the hole, but it'll still be easier.)
Honestly, you don't want to think about anything, especially pain, at the moment.
"-okay?" You feel a hand on your shoulder as your hearing starts to fade back in. The voice sounds like it's coming from that very oddly dressed nurse. "Nitori, I think I should take him back to Eientei with me."
"No, I don't think that would work. Last time we tried that, he disappeared into thin air."
You take a deep breath.
Your body feels shaky, but you slowly feel control return to your body.
So, you do the obvious thing and lay down, rolling onto your back.
From this perspective, you can see everyone looking at you worriedly. Except the reporter, who appears to be writing something down in her notebook.
The nausea slowly fades, and your senses return to normal. You feel exhausted, but thankfully you no longer feel half dead.
"Are you okay, John?" The nurse asks.
"Yeah, I'm fine now." You slowly respond.
A look of relief appears on Nitori's face.
"I'm sorry, John. I didn't know you were there, or I wouldn't have said her name."
"It's fine, Nitori." You reassure her.
"Do you think you can stand?" The nurse asks.
"Alright, let's get you up on your feet then. We should at least move inside so we can talk while sitting down." She holds a hand out. Grabbing it, you pull yourself into a standing position with her help.
You still feel just a little shaky, but you feel fine walking. It still seems to be getting better, at least.
"Let's head inside, then."
So you move inside and take a seat on a couch. The nurse is sitting in front of you in a chair.
"Well, before anything, I should probably introduce myself. I'm Yagokoro Eirin, Gensokyo's premier pharmacist. And you're John, correct?"
"Well, I'd like to try and figure out what's causing you to pass out. First, I would like you to describe as best you can what you know about what's been happening. Oh, but first, would you prefer to do this in private?"
