Eric and Vivian looked around at the interior of the DenLiner with awe. The place was a polished white metal interior, like one of the very expensive bullet trains in Japan. In the center of the car were multiple tables and a cooking area. This part of the train was the dining car, where three imagin, one light blue, one yellow, and one purple, sat down drinking some strange coffee.

As they entered, a young woman wearing a sleek black and white outfit came up to them and offered them a cup of the coffee. "Welcome to the DenLiner! I'm your waitress, Naomi. Would you like some of my original coffee?"

Kotaro whispered in Eric's ear. "Don't drink the coffee. She puts wasabi in it."

Eric shuddered. He knew well enough what wasabi felt like after all the times he and his parents went out for sushi. "Who puts wasabi in coffee?!"

Momotaros happily accepted the coffee, much to Eric and Viv's surprise. Teddy also obtained a cup, and the two sat down next to the other Imagin.

Ryutaros looked up at Eric, then turned to Kotaro. "Hey, who's this guy?"

"This is Eric, and he's our new Kamen Rider Den-O," Kotaro replied.

In that instant, Urataros paused in shock then spit out his coffee all over Kin. "New… new Den-O?!"

Kintaros wiped off the coffee, then turned toward the rest of the group. "Well, we do need someone, now that Ryotaro's gone."

Ryu stood up and walked excitedly over to Eric. "Alright! A new singularity point! It'll be exciting to shoot up some Imagin once again!" He then pointed his fingers in a gun formation, and made a slight "bang!" movement with his hand toward Momo.

Ura moved over to see Vivian, eyeing the girl interestedly. "And who might this be? Quite an innocent girl you are, but such a fiery soul you have. Just what I like,"

Viv looked somewhat grossed out at the turtle-like Taros, as Momo pulled Ura away.

"Either way," Kotaro stated, "they are now a part of the group. So, hopefully his fiery spirit will help us in the battle against Imagin."

"Quick question," Eric interrupted, "What are these 'Imagin' which you keep talking about?"

The Taros all looked at Eric with a strange look. Kotaro looked over at the boy and started to explain. "Imagin are humans from a future timeline that was erased from existance. They feed off of memories to keep themselves alive. They find hosts in people of the past, making contracts for their bodies in exchange for one wish."

"Similar to the wish Momotaros gave me," Eric stated.

"Well," Momotaros replied, "I wasn't going to use your body to go back in time to wreck the past, if that is what you mean. I have a train to help me do that!" he then chuckled jokingly, while the other Taros and Kotaro eyed him with hostility.

"Anyways…" Kotaro continued, "Once the host's wish is complete, the Imagin can use their host as a gateway through time to the host's most powerful memory."

"So, if these guys are human, why do they look all monsterous?" Vivian asked. The Taros then began to eye her angrily. "No offense, guys," she stated.

"Imagin take the form of what is in the host's memories," Kotaro replied, "For example, Teddy was based on the stories I heard from my grandfather."

"Which is why he looks like the powerful ol me! Eh, Neo?" Momotaros stated.

Teddy looked over at Momotaros and rolled his eyes. "Now then, should we go to our next destination?"

"Alright! We get to travel through time! This is exciting!" Eric exclaimed.

"Hang on…" Kotaro interrupted, "Something about that new Imagin we fought seems off. I need to investigate more on this before we leave."

Eric groaned. He really wanted to get started on his adventure. "Well, if we have to stay around here for a bit, then we might as well go say a proper farewell to my parents."

Kotaro nodded. "If we are to be going soon, you might as well. Teddy, let's investigate the spot where the Imagin disintegrated. I'll call the rest of you if we need back up."

The time train suddenly stopped, and Kotaro hopped off the train, along with Eric and Vivian.

The train of time, Denliner. Will the next station be in the past or the future.

When Eric opened the door to his house, his mother was there staring him in the face. "Where have you been? It's 2 o'clock! You're late!"

"Sorry, mom, we got lost," Eric stated. He cursed silently at Kotaro not being able to drop him off near noon.

"Whatever. Anyways, your father and I are going to be leaving soon. Your grandmother is going to be here till 4, so…"

"Mom, I kinda just came to say goodbye."

His mother looked at Eric like he was crazy. "Wha… what do you mean goodbye?!"

"Mom, you know how I feel about my life as it is. I don't want to live out my life the same boring way. Now, I finally have the chance to go on the adventure of a lifetime. Don't you understand?"

Eric's mom looked at him with hostility, then sighed in defeat. "You're right. You've never been known to be the type to do what other high-schoolers do. You have such an adventurous soul, Eric-chan. Wherever you're going, I wish you the best of luck."

Eric then moved in to hug his mother. "I love you, Mom."

Viv then spoke after Eric finished. "Don't worry about him, Mrs. Uchina. I will make sure he is safe."

"Of course, Vivian," his mom replied, "I know you will. Well, goodbye, Eric, and I hope you have the adventure you're looking for."

Suddenly, an elderly woman walked from the living room to the doorway. She looked different from her daughter, as her skin was a lighter color than Eric's mother. She had pearl white hair, and wore a gray coat and black heeled shoes. To Eric, his grandmother looked similar to the leader of MI6 from the recent James Bond movies.

"I knew that you would find your path, my young Eric. I wish you the best of luck. And also tell your blue warrior friend hello from an old friend." She then winked, which surprised Eric. How did she know about Kotaro? Unless she meant some other blue warrior.

"Goodbye, everyone. I'll miss you!" he called as he and Vivian ran off toward the DenLiner.

Kotaro looked around the battlezone, trying to see any evidence he could find. However, it seemed hopeless trying to find any evidence as to what caused the Imagin to reform like that, except for all the sand that it left behind.

"This doesn't make sense! When we beat it down the first time, it just reformed again!"

Teddy paused, realizing something. "Hang on, Kotaro. If the Imagin can reform out of nothing, then wouldn't that mean…"

Suddenly, a flash appeared, attacking Kotaro in the chest. The Tiger Imagin appeared in front of the two, claws at the ready.

Kotaro waited for the worst, when he heard a voice. "Leave him alone, fish-breath!"

Eric appeared out of the shadows holding his rider pass in his hand and the Den-O belt across his waist. "Let's see… how should I defeat you this time?"

He then heard the voice of Ryutaros in his head. "Ooh! Pick me! It's been soooooooooo long since I did battle!"

Eric rolled his eyes at Ryu's childish personality, then pressed the purple button on his belt. He then passed the pass over his belt, causing it exclaim "Gun Form!"

Eric began to change into Den-O, but this time, purple armor appeared around him instead of red armor, and his helmet resembled the mouth of a dragon.

He then pulled out the pieces of the DenGasher, assembling them into the form of a blaster, then spoke in the voice of Ryutaros. "Mind if I blast you up a bit?"

The tiger Imagin roared ferociously, causing Ryu to chuckle slightly. "Your answer doesn't matter," he stated, rushing into battle.

Den-O began blasting the Tiger Imagin, but because the Rider was moving so fast, some of the shots missed and hit the surrounding buildings. Den-O suddenly began breakdancing, causing a whole bunch of shots to fly out from around him, causing damage to the surrounding area. One blast nearly nicked Kotaro in the chest.

"Ryutaros, what do you think you're doing!" Kotaro shouted.

Suddenly, Den-O stopped, and it appeared as if the Rider was fighting himself on the inside. "Dude!" Eric's voice shouted, "We can't harm the surrounding area! Calm down!"

Ryutaros sighed. "You're no fun!"

"As long as you are in my body, I am in control! So, no more wild shots!"

"Fine!" Ryu groaned. He then moved toward the Tiger Imagin and shot him at point blank. The Imagin rolled across the ground and stared at something sparkling on the ground.

"Aha!" it shouted. It then picked up the object and gave it to a man waiting for him. Eric realized it was the same man he saw earlier! "I've granted your wish. Now it's your turn to redeem the favor."

Suddenly, the man split in half, revealing a time portal within him. The Tiger Imagin laughed evily, then walked toward the portal.

Suddenly, a mysterious figure appeared out of nowhere, and attacked the Imagin. Kotaro and Eric looked over at the strange figure surprised. The person was female, about 21, and had light brown hair. However, there were a few things that seemed off. The woman had an orange cat tail protuding from the back of her, and cat-like ears on her head. In her hair was a single streak of orange, and she smiled with a fanged grin.

"Traitor!" the Imagin shouted, "Why do you attack your own kind?!"

The woman spoke in a smooth, yet fierce voice. "Sorry to disappoint, but I have my own agenda."

"Who… who are you?!" Ryutaros asked.

"Just your average Imagin. However, my host has taken to calling me the name… Nekos," the woman replied. Nekos then sliced at the Tiger Imagin, causing orange claws of light to appear on her fingertips. She then stabbed the Imagin with her claws, and it fell over and disintegrated to sand.

The time portal suddenly closed, and the man reappeared. He looked at what had happened, then ran away scared.

Nekos looked over at the Liner crew and smiled. "Well, boys, I'll see you sometime soon. Au Revoir!"

With that, the Imagin emerged from her host, causing the tail and ears to disappear from her. She appeared as an orange humanoid cat, and wore clawed gloves to make her claws even longer and sharper. Then, the two jumped up onto a building, and disappeared.

"What was their big idea?!" Ryutaros demanded as he split from Eric, "Next time we find her, she's gonna get another thing coming!"

"First things first," Kotaro stated, "We must go consult Owner on this. He might know why these Imagin keep reforming."

"Alright!" Eric shouted, "Time for a Time Tripin' Ride!"

As the Denliner appeared, Ryutaros mused at Eric's comment. "Hey, that has a bit of a ring to it."

Notes: New OC? Yep. I'm somewhat tempted to say "Dang it, Waka, keep your french outta mah japanese stuff!", but whatevs. I just thought the french speaking was a good touch to Nekos. Also, my friend Livie is probs gonna rant me about proper french speech when she sees this. Anywho...

Anyother thing I should note is that it seems strange how Eric's grandmother knows Kotaro. Well, guess you'll have to find out later. Ha Ha! I'm Evil! :D

Also, a derp on my part in the last episode. I said Owner's outfit was white, not black. *facepalm*
