The victim who seemed dead at first becomes infected, aka a Zombie. Pala, who was bitten became a Zombie as well and chased the Running Man players and Detective Frick through the Train Car. Biting and turning the other Passengers into one of them as they pass by.

"Zombies are really here? Wait... how the heck do I know that word?!" Yuu yelled at himself as they tried their best not to get bit while running away. Soon they stopped at a small train car with restrooms before Kuga locked the door behind them, preventing the Zombies to break in but not for long.

"Guys are you alright?" Liu asked, panting heavily along with the others

"Yeah we're alright... how about you, Yuu?" Miyo asked Yuu who was staring distantly through the window.

"I'm okay, a bit hard running with both of my hands cuffed" Yuu replied

"Yuu's right, Detective! How about you finally let us go with these cuffs alright?" Lonky asked but Frick was acting differently. Lonky tapped Frick's shoulder before he jumped to turn towards them with the same eyes as the Zombies. The Running Man Players ran in a panic, they arrived at the dining car where Liu closed the door along with a safety precaution of an Iron barricaded door for added defense.

"Good thing the door has double locks" Liu muttered as they all panted after the long run.

"What the heck is going on?! Why is this happening!" Lonky yelled looking like his whole life was suddenly ruined, soon he jolted in fear when he stepped on something from behind, jumping onto Kuga's back before seeing what it was. It turned out to be a small crying Pululu in a hazmat suit.

"It's done, it's all over... the red virus" The Pululu muttered.

"The Red Virus?" Miyo muttered

"The Red Virus is spreading! The Vaccine! We need the Blue Vaccine right away!" Said the Pululu

"Do you know anything about any of this?" Gai asked.

"Yes I do... but I was sure I had the Red Virus... Oh! That guy stole it from me! He must have drunk the Vile..."

"You mean the big Pululu? Hmm it makes sense, that guy was a thief" Popo stated

"So where is the vaccine you were talking about?" Kuga asked while subconsciously choking Lonky with his left hand.

"The Vaccine is blue... The Virus has spread" The Pululu replied that seemed to be in a state of trance due to fear.

"Okay, but where is it?" Miyo asked but the Pululu kept repeating his words until Yuu spoke.

"That Pululu is a goner, the vaccine must be in the luggage car" Yuu stated before they all looked over at Liu.

"This is the map of the train, we are in the dining car and to get to the dining car we must get through 7 more train cars to reach our goal," Liu announced as he pressed the screen so he could lean on the wall but accidentally opened the door behind them were a countless horde of zombies was waiting for the door to be fully opened.

"Let's discuss our plan first," Said Liu as the others started to run away

"I don't think so" Yuu muttered before Liu and Popo realized the door was opened and the Zombies were loose, another chase escapade happened. They ran through the other train cars as the zombies bit and attacked the other passengers in the train. Lonky was bitten by the hand after attempting to get the keys from Frick since the door knocked him out but was bitten in the failed process. Kuga pulled him out and continued running without realizing that he was a bit. Liu closed the door along with the second lock behind them to catch their breath but Yuu seemed to be missing and Miyo noticed it.

"Are you guys okay?" Liu asked in concern.

"Wait where's Yuu?!" Miyo said with a loud voice as the others noticed the sudden disappearance of the bandaged man.

"Was he... left behind?" Lonky asked as the others came to the same conclusion.

"We must keep going, Once we get the vaccine, we'll bring Yuu back" Liu stated. The others nodded and agreed before they heard noises above them.

'What's that sound?" Asked Lonky

"It sounds like... they're making their way from the top of this train" Miyo replied before the Zombies dropped from the ceiling vent and landed on the train car in front of them, trapping the running man team in their current location. Lonky opened the door but the zombies were expecting them from behind the opening door, launching towards Lonky with a hostile intent before Kuga cleared the way by cleaving the Zombies away with his free hand. Miyo and Gai followed Kuga and Lonky while Popo and Liu stayed in their current car and closed the door. They thought they were safe but little do they know that the Pululu with the Hazmat suit was bitten and so tragedy happened to the bug and the penguin. Kuga kept clearing the way for them but not for long, Lonky was feeling the virus slowly making its way towards his brain.

"Come on! Go faster!" Lonky yelled as Miyo and Gai responded by clearing the way instead. They made their way to the other Car where they closed and locked the door, but Lonky doesn't seem to have any more time. Soon he turned into a Zombie and attempted to bite Kuga but his reflexes were strong.

"Are you kidding me?! When did he get bit! Never mind, stick to the plan!" Kuga stated, holding Lonky by the neck and using him as a battering ram for the zombies as they pushed their way forward to the last car. Kuga made it to the end while Gai and Miyo were left behind, once they ran towards Kuga, a zombie Pululu appeared in front of them, they managed to jump over it but not before Miyo get bit by the hand.

"One more door and the vaccine is ours..." Gai muttered before noticing Miyo on her knees, breathing heavily with a bite mark on her fingers.

"Miyo... no" Gai muttered once more before carrying her. Kuga suddenly threw them towards the next car before noticing the Lonky already bit him by the back of his head.

"Find the vaccine!" Yelled Kuga before detaching his train car from Gai and Miyo.  Gai watched as the train Kuga was on fell behind before mustering his remaining energy and carrying Miyo inside the luggage car.  He searched the darkroom with a very dim light in the luggage car for the vaccine until he finally found it inside a black case. He opened the case to see three vaccines, one red and the others blue.

"Please Miyo... be alright," Said Gai before making her drink the blue vaccine, she struggled at first after drinking but went quiet and peaceful afterward while Gai let out a sigh and sat on the floor with his back on the wall.

"Oh... thank God you're okay..." Gai smiled at her and brushed her hair before he heard the door open to see Yuu, limping towards them and looking injured.

"Yuu?! What happened? we thought you were turned into one of them?" Gai asked in shock

"As if... I turned invisible and headed out here through the roof of the train, I used my bandaged to grapple here before you could get any further and rested on the roof... but I got bit on the leg in the process" Yuu responded before sitting on the floor behind the other luggage as he started to breathe heavily.

"Oh no, do you need the vaccine?!"

"No I need a knife to cut my foot, of course I need the vaccine!" Yuu yelled before Gai tossed him the other vile and drank it after pulling the bandage on his mouth down and pulling it back up to cover it. Soon he started to feel the pain disappearing from his foot as he let out a sigh of relief as the train continued its way. After a few minutes of silence, Gai muttered while brushing Miyo's hair to the side.

"Can you believed that I'm holding her in my arms once more?" Said Gai while Yuu let out a silent groan, rolling his eyes to the side. "She smells like roses... her skin is so soft and warm... she's like an angel..." Yuu got irritated and groaned even louder before speaking.

"Dude, if you love her just confess to her" Said Yuu with an Irritated tone while Gai just smiled as part of his response, gazing at her porcelain-looking face.

"I would... but it seems that she likes you more than me or any of other guys... But I'm okay with that, we're friends and I'm happy if you two were to be together..."

"Shut up!" Yelled Yuu that made Gai jolt from shock before nervously looking over at Yuu who was staring at him dead in the eye. "Sorry for yelling... Look, I don't have feelings for Miyo, I just came here to win"

"But... I thought you did? You two seemed very sweet even the others think you like her" Gai responded as Yuu sighed before closing his eyes.

"You're letting your imaginations run wild Gai... just be quiet... I need a rest... this is the 2nd worst day of this time of year..." Yuu muttered before they rested in silence. After a while, the train stopped at the station and Gai exited first while Yuu was still resting. Gai was shocked to see a crowd of Pululu cheering for them, a robot appeared and announced them as the winners.

"Congratulations on the first two winners of the team around!" Said the robot as Charming Gold walked over to Gai and Miyo.

"Running Man hidden game: Escape the train, I commend your efforts in these courageous event" Charming gold announced.

"What? This is just a game set up by you?!" Gai asked

"From the Murder mystery to the Zombie outbreak, it is all part of the game! and the final survivors to make it to the final destinations are the winners of the game. Surprise! We got you two" Soon the remaining cars of the train arrived to see that the Pululu and the other Running men were okay. "First I would like to say thanks to the citizens of tree City for their amazing acting, Liu and Popo showed great teamwork in turning the tides, Lonky gave the dramatic climax as for Kuga. And the secret main character of the game, Pala! and Yuu... where...where is Yuu?"

"Looking for me?" Yuu responded after exiting the train and shocking Charming Gold and the crowd.

"Oh, I never noticed that you weren't eliminated, apologies... it seemed that there are three winners after all! The Love Triangle of Gaiyo and Miyuu!" The crowd cheered even louder for the three players, soon Miyo woke up as Gai gently placed her down.

"Who do you all love most? Gai and Miyo or Yuu and Miyo?" Charming Gold asked as Miyo and Gai let out a small blush while crowd cheered for the feline and the bandaged man, but Yuu became even angrier, stomping his feet loud on the ground as his eyes blinked in a red flash that caused the Pululu and Charming Gold to raise their fear levels at the peak in a split second.

"Yuu...?" Miyo reached for his shoulders but he stepped to the side to avoid her before speaking.

"Who said I had feelings for Miyo? Who said that this is a love triangle? That's right... it was all of you... Why don't all of you just mind your own freaking business!" Yelled Yuu that caused the crowd to feel frightened while Charming Gold tried to reassure him.

"Yuu, calm down, it's just to keep the crowd~" He was cut off by Yuu with a simple frightening gaze, showing the reason why he was called the Red-eyed Phantom.

"No, It's just... I don't understand why all of you would intervene in my private business! This is a race, not a reality show! It... IT TICKS ME OFF!" The crowd went silent along with Charming Gold as Miyo suddenly felt like her heart sank after hearing what he said. 

"Buddy... It's okay" Said Gai as he reached for his shoulder as well but Yuu slapped his hand away.

"DON'T TOUCH ME!" Gai stared at his eyes before nodding and taking a step back. "Out of my way or I will beat you all!" Said Yuu towards the crowd who cleared away for him.

"Yuu, we are all friends still right?" Gai asked as he stopped in his track.

"Friends? I don't have friends, this a tournament, you don't befriend your competitors because, in the end, it won't matter... there can only be one winner... Be real Gai" Yuu responded with a cold dark tone before leaving the area while the others were left in shock and a state of silence before Charming gold reassured them.

"Sorry for the sudden aura change everyone, you can go back home, the next event will be a big one" Charming Gold announced as Miyo felt Liu's hand on her shoulder.

"Are you alright...?" Liu asked

"Y... yes" Miyo responded

"What's up with Yuu? Why would he say he had no friends?" Popo said as all of them were left in confusion. A few hours have passed, it was 7:30 and Yuu was already asleep. The door to his room opened as a female walked over towards him as he slept. It was Miyo, running her hand down to his cheeks with an upset look on her delicate face.

"I'm sorry Yuu... I know I told you that I won't read your mind but... I can't stand here to see you like this... I need to know what's wrong with you" She rubbed both of her paws on his fairly built chest before transferring her subconscious in his mind. Memories of Yuu's past were seen in a form of video screens in all directions.

"Hey Gramps, do you think I can be as wise as you"

"Haha... Unfortunately No, but You can be the best of who you are, little Yuu" Miyo smiled after seeing his memories of how he used to be happy, soon he noticed how he changed in the other memories.

"Why did the grand elder spare him after what this kid did?"

"He should be punished for breaking our law"

"I never had any trust in that kid one but, an orphan like him does not belong to this tribe... Uh-oh he's coming!"

"Stay away from us freak!"

"Gramps... I don't belong here anymore and you know it. You should stop caring for me like I am still part of the tribe, You will lose all the respect of the tribe towards you."

"That may be true but I cannot let you leave... you are like my son..."

"I knew you won't... that's why I am prepared to use the forbidden move on you if you still prevent me..."

"I see... Then I won't stop you anymore... but always know that this is where you grew up so this is your home"

"I'll find a way to regain the tribe's trust someday... Goodbye gramps" 

"Goodbye and... happy birthday"  Miyo came to a sudden shock of realization.

"Yuu was Outcasted after breaking their Law, and it was his birthday at that time... November 29... wait that's today! That means it's Yuu's birthday, that's why he's in a bad mood, his birthday reminded him of his past" After saying that she warped out of his mind and back to her body where she removed her paw from his chest before gazing over at him. "You shouldn't keep those feelings inside you... I can always listen to you... like you are to me..." She subconsciously leaned forward at Yuu and planted a soft kiss on his forehead before realizing what she did and leaned back in an instant, covering her lips as small tears fell from her eyes.

"Oh no... I kissed him... I do like him..." Miyo muttered with a muffled voice before Yuu woke up but Miyo was already gone in an instant.

"Was someone here...?" Yuu muttered before shrugging and heading back to sleep
