"From what you explained, it sounds like Saisho wants to release parasyte spores into the atmosphere to guarantee the survival of parasytes as a species," Yūjin recapped. They were in the apartment.
"Yeah, that's the gist of it," Seijū affirmed as he pulled on a new jacket.
"In order to launch a substantial amount of spores into the atmosphere, one would need some sort of launching device," Yūjin concluded. "Am I wrong?"
"I guess not," Seijū said, looking in the mirror as he brushed his long bangs to the left. "They'd also need some way to create said spores. After all, they can't reproduce normally, or the result would be another parasyte like you, right?"
"Correct. They'd need to make a copy of their DNA and inject it into a hollow spore; in other words, the spores themselves are artificial. This bit of information, coupled with the necessity for a launching device, leads me to conclude that they must be operating out of a large laboratory, the likes of which is most likely hidden underground," Yūjin deduced.
"But to copy that much DNA in a short amount of time, all the parasytes would have to be in the lab at once," Seijū assumed. "So all we have to do is find the lab and destroy the equipment before they can use it! I mean, they've had two months since Saisho took over Ayumu's body to build it, so if we destroy it, that gives us two months to hunt and kill the parasytes."
"Maybe not," Yūjin interjected. "For all we know, they haven't even begun to build it yet, or maybe they didn't start until a week ago. We don't know how fast they work. However, regardless of what scenario it is, they surely have a location already. We just need to find that location."
"And how do we do that?" Seijū asked. Yūjin thought for a moment.
"We head back over to their meeting place. Surely, they must have some sort of plan there if they were able to meet there, assuming Saisho or one of the other parasytes didn't already retrieve it," Yūjin decided.
"What if they have retrieved it? What then?" Seijū said.
"We'll have to take our chances. It's either that or nothing," Yūjin explained.
"Alright, then. Plus, that has the added bonus of me recovering my flamethrower. Speaking of which, I need to restock on propane and alcohol to fight these parasytes," Seijū added.
"I went through the liberty of doing that for you," Yūjin revealed, walking over to a cabinet. He opened it; inside was a belt of propane cans and several bottles of alcohol. Well, that's convenient. Yūjin handed Seijū an empty backpack; Seijū filled it with bottles of alcohol and slung the propane belt over his shoulder, pulling the bag onto his back.
"Let's go."
"We're here," Seijū announced as he stopped the car on the side of the road. He and Yūjin stepped out of the car. Seijū looked over at the building. The window hasn't been replaced yet. I guess the parasytes don't really care about things like that, huh...?
"We'll split up to maximize efficiency," Yūjin planned.
"No!" Seijū countered. "That's a bad idea! Without you, I don't have anything to defend myself with!"
"Yes, you do, Sei. You have alcohol bottles and a knife, and you'll soon have your flamethrower. You'll be fine," Yūjin reassured. ...Yeah, I guess he's right. "We'll meet in the lobby in exactly one hour."
"Agreed." The two of them stepped inside; the door was still unlocked. Yūjin entered the stairwell; Seijū opened the elevator and stepped inside. After pressing the buttons, he had but to wait. Wait a second. What happens when we do find the lab? Obviously, we'll need to stop them from releasing the spores. But...How? How will we know what machinery to destroy? How will we destroy it? Can we destroy it? Plus, if all the parasytes are there like I suspect, then it'll just be what happened here all over again. What'll we do then...?
The elevator slowed to a halt; the door slid open. This is it. Seijū stepped outside the elevator and into the conference room. The place was completely charred from the fire from before. Seijū scoured the floor for his flamethrower. Over there! He walked over to his flamethrower and picked it up, refueling it immediately.
"You've returned? That was unexpected," a voice greeted. Ack! Seijū whirled around. A parasyte stood by the doorway. "Saisho sent me back to retrieve the blueprints, but it seems you've returned. Did you, by any chance, find them?"
"...Blueprints?" Seijū wondered aloud. ...Damn it, I said that out loud! He probably wanted to know if I had given them to Yūjin, but now he knows the truth...! He pulled the trigger on his flamethrower; however, the parasyte sidestepped, avoiding the cone of fire. He lashed out at Seijū, knocking the flamethrower to the ground. Shit!
"AUGH!" Suddenly, after a brief moment of intense pain, his senses went numb. Seijū looked down at his chest. No...way...! The parasyte's blade was stuck in his chest. He...got me! The blade withdrew, and the parasyte regained its human appearance. I can't...move... Seijū fell to the ground, too weak to stand. His vision had become hazy.
In a blur of movement, Yūjin stepped into the room and seemingly decapitated the parasyte. He ran over to Seijū and started saying something. Seijū tried to respond, but couldn't. He started seeing black spots which slowly expanded into an abyss of darkness.
