A/N: I DO NOT OWN ANY OF LAST OF US OR YU GI OH 5DS! ALL RIGHTS GO TO THE CREATORS OF BOTH!

Epilogue

Yusei was standing at the overlook, staring at his bite mark and debating if he should've found a way to stay and create the cure. Yes, he was happy to be back at New Domino and alive; but at the same time, he knew the other world was suffering due to the actions of his friends.

"What do we have here?" came a familiar man's voice. Yusei turned to the man, unintentionally going to the left so his mark would be able to be seen. It was Halldor, Dragan, and Broder. "The man returned from disappearing for a year and three months? We had heard the rumors but didn't think they would be true."

"It's more complicated that you think," Yusei responded.

"Rumor has it that you went to another world," Dragan stated. "But that wouldn't be possible, would it?"

"I did, though," Yusei replied shocking them. "I was somehow forced onto another Earth with some bad problems and was after an apocalypse."

"What proof is there of that?" Broder asked.

"First of all, this," Yusei replied holding up his bite mark. They went wide eyed. "This is a bite mark from what they called Infected. In that world, an infection called the Cordyceps Brain Infection had created a worldwide pandemic. It's a fungal infection that once it's in you, takes away your higher brain functions, makes you aggressive and want to kill anything. It spreads by someone breathing in spores of the fungus or getting an Infected's fluids into you. There are four stages of Infection after you turn: Runner, Stalker, Clicker, and Bloater." He flung a folded paper at them. "This holds a picture of each type of stage." They unfolded the paper and were shocked by each form.

"If you were bit by one of these Infected, why didn't you turn?" Halldor asked.

"I'm immune to the virus," Yusei answered.

"How is that possible?" Dragan asked. "And what have you been doing there for the past year and three months?"

"For the past year and three months, I've been working and fighting with a group called the Fireflies. The Fireflies were dwindling down in numbers as the military were hunting us down, trying to kill us off. Those who weren't Infected were typically kept in Quarantine Zones, which was run by strict laws and one break of them would get you killed. The military saw the Fireflies as terrorists because we would do all we could to keep their armories and abilities to hunt us down lower while getting what we needed to survive. That's all we were doing, though: surviving. The Crimson Dragon eventually brought my friends to that world, to get me off that world. But I was following the leader of the Fireflies', Marlene's, orders to get to Salt Lake City Hospital in order to find out what made me immune and make a cure," Yusei explained.

"And did you make a cure?" Halldor asked.

"In order for the cure to be made, I had to die," Yusei answered leaning back. They went wide eyed. "The Cordyceps Brain Infection growth wraps around the entire brain." They then understood. "My friends wouldn't allow that, however, and got me out right before the procedure to get the growth could begin. I had willingly agreed to do the procedure so that world would've gotten a second chance, but it didn't happen and that world is probably suffering a lot more because of it. In fact, some people would say that they are more afraid of normal people than the Infected. I can understand that thought process."

"Why is that? Wouldn't you be more afraid of these things?" Broder asked.

"Those are more predictable and easier to deal with than you would think. At least, compared to a normal person. Gangs would usually take over cities. In one at Pittsburgh, they were a gang that took over the Quarantine Zone there by killing all military there. Anyone coming in they would shoot on sight and look for any supplies the victims had on them. After that, they would either burn their bodies or eventually eat them. There were other gangs that you were lucky to find them eating normal foods. But those gangs' normal source of food was other humans. The military was merciless and you couldn't really know what to expect from them, which is why the Fireflies would do all we can to hold them back. I've seen families get torn apart by Infected. For instance, when two brothers met me and my friends while trying to get out and away from Pittsburgh area, one got Infected. When he began to turn, his brother reluctantly shot him before shooting himself." They were struck with absolute shock as he explained all the world's problems that came with non-Infected. "Normal people are something probably more dangerous than Infected. And Infected had taken up over sixty percent of the world."

"Sixty percent? Are you serious?" Broder asked.

"Dead serious," Yusei answered. "If I had been able to make the cure, maybe things would've gone back into order and people would start surviving and taking back their life from the Infected."

"Or maybe things would've turned into chaos with one group having the cure while no one else did," Dragan stated.

"That is another possibility," Yusei responded calmly. "But it doesn't matter. There's no way to make a cure now. I'm not on that world anymore and they don't have what they need to make one. And I'm sure it's only getting worse."

"You did what you could, Yusei," Halldor told him. "I'm sure another will come who is immune."

"Maybe," he responded.

"Did any of your friends get bit?" Dragan asked.

"Leo did," Yusei answered. "He turned out to be immune as well."

"Huh," was all Dragan responded with.

"What brought you to New Domino anyway? It's not like you to just come to this town all of a sudden," Yusei asked.

"When we began to hear rumors of you finally returning, we wanted to see if it were true or not," Halldor answered. "After all, if the one man who can defeat our gods disappeared forever, who would we have to duel against when the next tournament comes along?"

"I understand," Yusei replied. "If you ever want to duel again, I'll be happy to face you again."

"And when we do, we'll see who comes out on top," Halldor responded folding the paper he still had back up and tossing it to Yusei who caught it with ease. "Until then, Yusei."

"Until then, Halldor," he responded and the three men left.

Yusei turned back to New Domino and thought, 'Sometimes being back feels like a dream. I don't know if I'll end up going back there… If I do and Marlene and the Fireflies are still around, I know that means I am really supposed to die there to make the cure. And I'll do so for the Fireflies. Whatever reason the Crimson Dragon had for getting my friends to save me, whatever reason it was that I originally went to that world, I'll figure out what I'm really supposed to do as my final destiny. Whether it's making a difference in New Domino, or dying for the cure on the other Earth. I'll find out. But until I do, I'll focus on keeping the peace we have here and making sure the pandemic on that Earth doesn't reach here.'
