There! Seijū looked down at his newly constructed handheld flamethrower. It was built using simple household items, like aluminum foil, staples, cans, and the like. The only things he needed to buy were canisters of propane gas to serve as fuel. He looked up at Yūjin, who stood next to him. He had pulled on a white shirt and trimmed his hair, his hands in his pockets.

"I didn't realize you knew engineering so well," Seijū remarked. Yūjin smirked.

"I'm a parasyte, remember? I learn stuff extremely quickly. I even think faster than you, Sei!" Yūjin pointed out. Show-off.

"At any rate, the flamethrower's done. Let's go," Seijū decided.

"Go where?" Yūjin asked as Seijū stood up.

"Where do you think? We're going parasyte hunting." After having slung a belt of propane canisters over his shoulder and pulled a backpack onto his back, Seijū walked towards the front door.

"You're serious about this, aren't you? Well, what's your plan, anyway?" Yūjin inquired. Plan? Seijū stopped.

"Er...We can just drive around until...until you receive a signal from a parasyte," Seijū stammered. Yūjin thought for a moment.

"Actually, that may not be such a bad idea," Yūjin agreed. "Oh, and you should take this as well." He handed Seijū a liter of water.

"What's the water for?" Seijū wondered aloud.

"In case you catch fire!" Yūjin winked jokingly at Seijū, who sighed.

"Let's go."

"Stop the car," Yūjin ordered. A parasyte? Seijū pulled up the rental car to the side of the road, stopping.

"Did you detect a parasyte?" Seijū questioned. Yūjin nodded.

"It's 150 meters away. 135 meters. 120 meters. It's moving fast; it's probably in a car," Yūjin deduced. Seijū opened the car door, stepping outside the car and onto the street. Yūjin followed. "What are you doing?"

"If it's coming at us in a car, I'll hail down the car," Seijū said.

"That's stupid. It'll either ignore you or run you over!" Yūjin objected. Huh? Movement in my peripheral vision...

"Too late now," Seijū revealed. Yūjin turned around. A car sped towards them. Alright, here goes nothing. Worst case scenario, Yūjin can save me. Seijū waved his arms at it. However, it didn't slow down. On the contrary, it sped up. Damn it! ...Yūjin, you're up.

Yūjin put his arm out, morphing it into a powerful claw. The car smashed right into his hand; the entire car was crushed by the force of the impact. Several shards flew into the air, landing around Seijū. Phew, that was pretty impressive. Something knocked open the car door, and a person—rather, a parasyte—stepped out of it, calm as ever.

"Why did you stop me? Do we not have a meeting to attend?" the parasyte questioned.

"No. We don't have a meeting," Yūjin retorted. He attacked the parasyte; the two of them engaged in combat. Alright, then. I'll use my flamethrower only if absolutely necessary; I need to preserve my propane. If he needs me, I'll—wait, what was that?

The other door on the car flew off. A figure climbed out of the car. Shit! Another parasyte! Yūjin, are you—! Yūjin was still fighting the first one. What do I—that's right, the flamethrower! With trembling fingers, Seijū pulled the trigger on the flamethrower. Flames burst from the nozzle for a few seconds before Seijū stopped firing. Instantly, the parasyte wailed. It split in half and fell to the floor in a heap, struggling to pull itself together. It...It worked...! Seijū pulled out a knife and repeatedly slashed at the heap. Die, die, die! After a few seconds, the heap began to wither. The parasyte was dead.

I...I did it! I killed a parasyte! Seijū sighed in relief, lowering his weapon. To his right, he saw Yūjin finally stab the other parasyte in the chest. He slashed it into multiple pieces, killing it. Yūjin turned towards Seijū; his eyes widened slightly when he saw the withered heap on the floor.

"There was another one? And you killed it?" Yūjin asked, surprised.

"I did it...! I killed it!" Seijū exclaimed excitedly. Yes!

"I take it the flamethrower did the trick?"

"That's right!" Seijū confirmed. "You know what this means, right?! These things aren't invincible! We can take 'em!"

"So now what? You've proven it to yourself. What now?" Yūjin asked.

"What do you mean 'what now'? We keep going! These are just two of them!" Seijū declared. These damn parasytes are gonna pay for what they did to Kussaku! Every last one of them! He threw open the car door and sat in the driver's seat. "What are you waiting for, Yūjin?! Let's go!"

Damn it, where are they?! It's like they've just disappeared!

"Yūjin, where are they?!" Seijū yelled out of frustration. Yūjin didn't even flinch. He thought for a moment before replying.

"Did you stop to think for a moment that maybe there simply aren't that many parasytes?" Yūjin pointed out.

"Of course I did! Kussaku...He said there were a bunch of eggs, not just one! Those eggs had to have gone somewhere!" Seijū explained. He turned left.

"But you can't live the rest of your life hunting down parasytes! I didn't know your brother, but I'm sure he wouldn't have wanted this! Plus, what if—" Yūjin argued before stopping mid-sentence.

"What is it? You detected another one?" Seijū asked. Yūjin didn't respond; he seemed flabbergasted. "...Hey, Yūjin."

"No...Not exactly," Yūjin muttered enigmatically. Not exactly?

"What do you mean?"

"There's...more than one...There are...way more than one...!" Yūjin stuttered. More than one? Wait...Is this...the meeting...?

"...How many?"

"There are so many I-I can't tell!"

"Where?"

"Three hundred meters ahead, but—"

Seijū slammed on the pedal. The car sped down the street.

"What are you doing?!" Yūjin exclaimed.

"Following the signal. If they're meeting, then we've got them all together, so hunting becomes much easier," Seijū explained as he sped towards a large office building at the end of the street.

"No!" Yūjin shouted, grabbing the wheel and swerving out of the way. His arm twisted; he also pressed on the breaks. The car skidded to a halt on the sidewalk.

"Why'd you—!"

"You can't fight that many! They'll kill you in an instant!" Yūjin yelled.

"Like they did to Kussaku?!" Seijū countered. "Look, if I have a chance to avenge him, I will, with or without you!"

"But—"

"You're not even human! You're a parasyte, for God's sake! I don't know why you haven't killed me yet, but I'm not gonna let you stop me from killing the other ones!" Seijū roared before stepping out of the car, slamming the door. Yūjin just sat there, processing what Seijū had said.

I don't need that thing! Yūjin may seem human, but he's just a parasyte! Seijū stomped down the road towards the building. Here it is. He tried the bottom door; surprisingly, it opened. Seijū stepped inside; the door swung shut behind him.

It's surprisingly dark. But I can still see, so whatever...So what now? Seijū crept through the lobby towards the front desk. Hm? A directory? He picked up a directory from the front desk. Maybe this'll have something useful. Seijū perused the directory until stopping on the fiftieth floor. There was a massive conference room there that could apparently fit up to one hundred people. Here! They're probably here!

After leaving the directory on the desk, Seijū headed for the elevator. He tried the button; the elevator door slid open. Alright, here I go. Seijū punched in the floor number, and the elevator began to ascend. Tenth floor...Twentieth floor...Thirtieth floor...

Fiftieth floor! Seijū exited the elevator. To his surprise, the lights were lit on this floor. He stepped outside and crept towards a nearby door. He pressed his ears on the door and heard voices. This is them...They're on the other side of this door...!
