Feel free to skip to the end since the beginning will be the same plot as the show, although the next chapter will be different.

 It was nighttime at Tree City, Yuu, Kuga, and Gai were sleeping. Popo was unboxing his new magical cards. Liu, Pala, and Lonky were in Kuga's room hanging out but Kuga seemed to be missing all of a sudden. At that time, Miyo was running along the dark hallways in fear. She waited for the door to open and when it did, someone appeared behind her and abducted her with only a short scream before disappearing into the shadows. Gai and Yuu were awoken by her scream despite their room were far away from her.

"Miyo!" Said Gai and Yuu before getting up from their bed. Gai ran down the hallways in search of her while Yuu covered his chest with bandages and his grey jacket but before he could get out of his room, the same person appeared from behind him and whacked him behind the head with a right cleave of that person's fist, causing him to fall unconscious to the ground before getting abducted as well. 

Meanwhile, Lonky, Liu, and Pala were still in Kuga's room, having the time of their life. 

"This Potion of yours is quite strong, this could help us beat Kuga!" Said Lonky before taking a sip from Pala's potion.

"Come to think of it... should we be doing this in Kuga's room?" Asked Pala as they gazed over at Kuga's empty bed.

"Where did he go in the middle of the night anyway? He has been gone for a while, I hope nothing happened to him"

"Oh please, why are you worried? He's huge nothing can do him harm" Lonky replied reassuringly Until Pala spoke.

"By the way have you guys heard of the... Kuphaman?" Asked Pala in suspense.

"Kuphaman?" Liu asked without knowing who it was. Lonky seemed to know judging by the way he looks.

"You mean the Serial abductor? I hear it's all made up" Lonky replied.

"What is the Kuphaman?"

"They say he has been abducting Running Man players for centuries, pretty much from all the tribes too," Pala responded to Liu's question.

"I haven't heard of this take until now" Said Liu

"That's because it's not real, it's just another spooky story made up to scare people"

"I beg to differ Lonky, They say he's so strong that when he target's you, that will be the end of it, it's useless to resist. I have heard stories that contestants suddenly disappeared. All of them are due to Kuphaman." Pala responded with a nervous tone and shivering legs.

"So he just takes people for no reason?" Asked Liu in suspicion.

"yes, and they call him Kuphaman because of the strange breathing sound he makes all the time, kinda like Darth  Vader but deeper and low. He doesn't care where and when he takes you because once you became his target, not a single person comes back"

"What's the purpose of kidnapping them"

"Hey, I'm telling you It's all just Hogwash. I can't believe your tribe still believes in that childish ghost stories, you guys are so gullible, it's funny" Just as the Giraffe said that an explosion of thick smoke appeared in the room. It was Gai, using his Jutsu to blink towards the room, Lonky jumped on Liu's arms in fear and shock while Liu let out a sigh.

"Gai what's wrong?" asked Liu.

"Miyo... Kidnapped" Gai explained everything to them in a matter of minutes although Pala and Lonky barely understood what he said since he was very fast so Liu gave them the details.

"So you were asleep until you heard Miyo screamed and dashed in the dark halls and when you arrived you saw a weird man and followed him to the end of the halls and all of a sudden they disappeared?" Liu repeated so the others may understand.

"Miyo was desperately calling for me but I failed to save her... I wanted to tell Yuu so he could help me but he was gone as well, it seemed that he was captured as well"

"Well... maybe you're just hearing things since you think about Miyo all day long" Lonky stated which may have made Gai angry.

"That's not it! Yuu was not in his room as well and his bed was messy, he is always organized!"

'Well, Yuu is always mysterious, maybe he just went to the kitchen to eat some sweets" Lonky continued to disagree.

"Then what about the weird dude I saw?"

"Who now? The guy who vanished like a ghost? You expect us to believe that? Did he happen to breathe like someone wearing a very thick gas mask?" Asked Lonky with a laugh but the expression that Gai had was beyond belief.

"Lonky... how did you know that?" Asked Gai that shocked everyone in the room. "He was breathing very heavily like that Darth Vader from that old Sci-fi movie" 

"It's Kuphaman!" Pala yelled in fear.

"But it can't be..."

"Kuphaman is here and wants to kidnap us!" Pala muttered hysterically as Gai gripped Pala's Scarf.

"Tell me who that is!"

"Easy Gai, nothing is confirmed yet so we should look for clues," Liu said with a reassuring tone.

"I got your clue right here" Gai responded before showing them a piece of old fabric that he found on the floor where Miyo disappeared.

"This looks like a piece of bandage like what Kuga wears on his arm or what Yuu wraps on his body" Liu muttered as they heard Lonky let out a loud Laugh.

"Oh man, I almost fall for it"

"What are you talking about Lonky?" Asked Liu.

"They're making us play a game without letting us know like last time. Kuga and Yuu's mission is to abduct us.  Whoever survives until the end will win. That's why Kuga and Yuu have been out late at night these days, well Yuu seemed to be hungry all the time" Lonky assumed with his cocky smirk as if he solved a longtime unfinished case.

"That's ridiculous, Lonky. They wouldn't hold two hidden games in a row"  Gai stated.

"If you don't want to believe me then go ahead, Look up there, there's a camera" Lonky pointed at the top right corner of the room where a white security camera was focused on them.

"This isn't a game, the breathing was the same, this is Kuphaman" Pala muttered as they went outside to investigate. Soon Popo became the next target by the mysterious man. In the meantime, Liu and the others were investigating the hallways until they arrived at Popo's room. Liu was suspicious seeing that Popo's cards were on the floor and he was nowhere to be seen as well while Lonky was looking calm and relaxed since he still believes that this is part of the game. Not long after, Liu and the others exited the room and returned to where Gai saw Miyo disappeared with the Large Man. They investigated the area for clues or hidden doors until they heard Pala's faint scream, Liu turned to look to see that he was gone. They gaze over at the black portal and suspected that he may have been eliminated in the game as Lonky suggested but Gai became angry and refused to believe that it is all a game.

"This is not a game! Miyo's scream was real! Forget this, I'll look for her o my own" Gai stated in anger before jumping into the portal, Liu accidentally fell on the portal as well. Lonky assumed that they were out and won until he became the last target. The door closed in front of him as the tall and large man walked towards him slowly, its eyes and the mask were colored in bright dark red before abducting him without a trace. Meanwhile, Kuga and the others who have been abducted were put in a white square room similar to where they are often placed once they are eliminated. Kuga punched the wall several times in sheer anger, he felt frightened and took a step back until he bumped into Miyo who was just as angry as Kuga.

"What do you want?! Get out of my way!" Miyo yelled at Popo before retracting her claws and scratching Popo deep into his face. "Just you wait! You'll never see the light of them again! I'll tear him up! No one humiliates me like that and gets away with it!"

"I know you two are upset but why don't you just take it out on the guy once he comes back" Pala stated that captured the two Cat's attention.

"Yes! I'll crush him as a flee!" Yelled Miyo.

"No, I'll get him I promise you that" Said Kuga who had a terrifying penance stare but to made Miyo angrier.

"Are you sure about that? I heard he knocked you out in one blow" Said Popo that made Kuga angry at him instead. "Jeez it's not my fault he kicked your butt"

"Popo just shut up! What he did to me was way worse!" Yelled Miyo remembering how she was carried by the man with one hand like a wild animal.

"Well, you shouldn't have been walking around at night," Popo responded before she clawed him again.

"Hey after he caught us, why did he bring us to this place? And where's Yuu? I guess he did just went out to eat some doughnuts." Pala asked.

"Who cares?! He treated me... like I was a... like a... Like a RAGDOLL!!! RAAAAGHH!!!" She gripped her own to desperately let out her rage onto her own. "Unlike Yuu who treated me like I was special with his pats!" She blurted.

"Wait what?" Pala asked

"Nothing!"

"Hey, guys by the way... didn't Kuphaman looked familiar to you? I think I've seen him from somewhere... Oh! I remember You know that large black hand who always pulls us out of the game? I think That is his hand" Popo stated.

"Yeah but why now? We aren't playing a game" Pala asked as Kuga let out his rage in the wall with a powerful punch that shook the inside of the walls and towards the upper levels where Liu and Gai were in after falling from the Portal they took. Both of them ran towards the other side of the path and managed to open a portal towards every room of the running man players but the others were indeed gone. They fell once more on the last portal and landed on the hallways where they can hear a faint scream of a scared girl. It was Lonky, who managed to escape the clutches of the Kuphaman. The tall, large hooded figure dashed towards them that made Liu run but Gai stayed behind and fought the beast along with his clones but it was too powerful for him and ended the fight quickly with one punch. It chased after Lonky and grabbed him along with Liu who was grabbed by the leg by Lonky and disappeared into the portal where Gai jumped in as well. The Portal appeared in the room where the others were and tossed Lonky and Liu in it, Gai attempted to tackle him but the Kuphaman evaded, or so it thought when Kuga pulled him by the hand and into the room with them. With the light shining brightly upon the beast, it was clear that it looked like it was from the Bars tribe as well but Kuga's rage prevented him from suspecting the beast.

"hey! When I get my hands on you I will rip you apart!" Yelled Miyo who was held back by the others.

"No... this one belongs to me" said Kuga with a serious look as he stood face to face with the beast who was taller and bigger than him. Both of them did the same combat stance before rushing towards each other with hostile intent. Kuga threw a powerful right punch but was easily caught by the beast with an open palm. They took a step back before throwing punches at each other, both of them seemed evenly matched in strength until the game changed when Kuga lost focus and threw a random straight punch towards the Kuphaman. It countered it by letting it pass by him to the side and slamming his shoulder towards Kuga with incredible strength and power that sent Kuga flying towards the wall, but the blow was too powerful that even the wall was pushed back by a few meters along with Kuga.

"Is that the best you got? Come! try again!" Yelled Kuga with a smirk before his right paw glowed in purple and dashed towards the beast and used his power directly at him, sending the Beast flying at the end of the wall with a paw mark behind him but it had no effect what so ever. Soon it did the same stance Kuga did, his Right palm glowing the same way that alerted Kuga.

"Wait that stance is~" Just as Kuga could finish what he was about to say, The beast jumped towards Kuga and used the same power towards him. Kuga felt a sudden nerve and out of reflex, he evaded by jumping to the side. He turned to face the wall behind him only to be shocked when the Beast's paw print was bigger than his, Tenfold. The beast stood behind Kuga and was about to use the power again but it suddenly stopped, Kuga reached towards its hood until robots appeared out of nowhere and pushed him back.

"Get out of my way! let me talk to him!" Yelled Kuga as he cleaved the robots away but Liu and the rest as Gai held Miyo to prevent her from doing something she might regret. Pala picked up a piece of red crystal on the floor that was dropped by Kuphaman before he disappeared into the portal. 

"Guys calm down!" Liu yelled reassuringly.

"Liu let me go!!" Yelled Kuga.

"There is a huge gap between you two! You can't beat him!" With those words, Kuga realized the difference and calmed down, the same goes for Miyo.

"Tch! I'll get my revenge" Miyo muttered as a portal appeared, all of them over at the black portal to see Yuu walked out of it with bruises and dust stains on his shirt with his eyes glowing in red colors like at that time at the Train station.

"Yuu? Where were you?" Asked Gai.

"What happened?" Miyo asked noticing his injuries before Yuu fell on his knees.

"I fought... someone..." Miyo and Liu ran towards him and assisted him up.

"Who did you fought?" Lonky asked in curiosity and concern.

"A girl... but I defeated her... what happened to you guys?"

"We lost a fight..." Kuga responded.

"Figures... so... i'll just pass out now..." You suddenly became unconscious Miyo was very much concerned but was relieved when he was snoring. another portal appeared which was their way back to their dorms. All of them went back in while Liu and Miyo placed Yuu on his bed gently before leaving his room. the event of tonight haunted them all while Yuu just slept happily, what did happen to him?
