Mystia and Vante were back in their room, with Vante's demonic protusions and scythe gone, and Mystia's foot still being massaged by the bird herself. Both were sitting down beside each other, like the night before.
"Yes, I'm convinced this isn't a dream. And if it is, at least I have full control of myself. I never had that when I dreamt before."
"Okay, good. You're a smart one; outsiders usually keep telling themselves it's a dream, but that gets them eaten sooner or later. So can I ask you again: what happened a while ago?"
"Uhhhh, let's see. Oh, that's right, I don't know."
"Gosh, I should probably stop asking. It's making my head hurt."
"Yeah, and I thought you would get it the first time-"
"Shut up." Mystia was exasperated. The sudden rush of energy had left both her and Vante without anymore of it. Vante's head was about to use Mystia's shoulder as a head rest, but this was quickly averted with a shove.
Like last night, there wasn't so much to talk about. Only the seldom thuds of feet on wood and the unchanging view of wooden walls kept them company.
Vante was the first to strike some small talk. "...I heard you a while ago. You said something like 'being able to do something again.' What did that mean?"
The bird nodded. "In Gensokyo, we don't fight like how we did a while ago. Not entirely. We have rules to follow; they're called the 'Spell Card Rules,'" Mystia held her hand out and, out of sheer willpower and energy, formed a bullet, "This bullet here is usually what we use for fighting, but they can come in any shape or object. And if you saw before, there are also lasers."
"So, they kill? You killed a blob with one," Vante recalled the time when he saw Mokou and Kaguya fighting with their own mass of bullets. "And what about if there were a lot of them at once?"
"They... don't kill," was Mystia's immediate reply, "Huh. Come to think of it, how did those things die? Anyway, what if there were 'a lot of bullets?' Depends. Did they shout something before the bullets appeared?"
"Yes."
Mystia sighed. "Then that's a spell card. You see, everyone's got one, and every card is different. Okay, sometimes, two people have the same spellcard, but that's rare. The shrine maiden, Reimu, says it's for variety, but it's really just so that we can dump a whole bunch of bullets on opponents," she took out one of her own spellcards, waving it around in front of Vante, "Besides bullets, these cards can do a whole lot more. Mine's specialize in making you go nightblind. Then there are those that make people invincible, or really fast, some stop time-"
"What?" Vante sat upright at those last two words, "say that again?"
"You humans," Mystia grumbled, "If you're surprised, wait 'til I get to Yukari. Your jaw will have nothing to hold on to."
"Okay, so how does this tie in to not doing something?" Vante began to sound extremely annoyed.
"The rules say that we can only fight with bullets. There were some times we could go hand-to-hand, but that was all blunted by magic. Can you imagine how nice it feels to finally dig through skin and blood?" Mystia, as if smelling something fragrant, took a deep breath of the imaginary scent.
"...alright, I get it already, you're a sadist. You don't need to rub it in my face."
The youkai growled audibly. "Okay. Hey, I have a great idea: let's get that scythe of yours out and see who's the sadist here!"
"...can we just go rest now?" they said at the same time.
