On board the DenLiner as it sped through the sands of time, Kotaro told Owner what would happen as the elder man ate his rice dish, while the Taros and Vivian sat at the table to eat. However, Viv soon realized that Eric and Momotaros weren't at the table with them.

"Hey, guys, where's Eric?"

"Who knows?" Ura responded, "I haven't seen him or Momo for a while."

"You don't think they got left behind, do you?" Kin asked. As he asked that, they heard a smash on the top of the roof. The Liner crew jumped as the DenLiner returned to its normal path, then the smash happened again.

"What's going on up there?!" Kotaro demanded. Meanwhile, on the top of the DenLiner, Eric and Momotaros practiced their sword attacks on a wooden dummy the two had brought up there.

"My Hissatsu attack, Part 3!" Den-O shouted, as he slashed the dummy with the detachable blade of the DenGasher, then cleaving it in half, causing a clang on the top of the time train.

Suddenly, Kotaro popped his head out the window. "What are you guys doing up there?"

Den-O waved to Kotaro, then spoke in Eric's voice. "Hey, Kotaro. We're just practicing our techniques for when we fight Imagin."

"Yeah! Together, we're gonna kick Imagin butt!" Momotaros added. With that, he cleaved the dummy again with another Full Charge.

Rolling his eyes, Kotaro put his head back inside as the Rider continued training. Later, Eric stopped Momotaros for just a second to talk to him.

"Hey, Momo, why were you so accepting of me after I made my wish to come with you guys?"

Momotaros paused for a second, then answered. "I don't really know. I guess part of it is because you remind me a bit of Ryotaro."

"So, this Ryotaro guy was the original Den-O?"

"Yeah. He was a bit of a coward at first. He had really terrible luck, but one thing you could never forget about him was his true strength and his devotion to his friends."

"You think I have true strength?"

"Well, I shared a body with you, and you were able to stop me, so I guess I should know you have true strength."

Den-O looked over then to see a familiar face in the sand. "Hey, that's the cat Imagin that I saw earlier!" Eric shouted.

"How did she get in here? Unless…"

With that, Den-O climbed inside the train again, and ran to the front of the DenLiner. Climbing onto the DenBird, the front part of the driver car opened and the motorcycle popped out.

"Guys!" Kotaro shouted as the DenLiner slowed down.

"Sorry, but we've got a cat to go see!" Eric called back.

Kotaro groaned annoyed, then changed into New Den-O. "Owner, can you use your bike to power the Liner manually? I'll use the spare DenBird to chase after those two."

"No problem, Kotaro-chan," Owner stated, "I needed some good exercise today."

New Den-O ran to the back of the train, where two spare DenBirds were held, and jumped onto one of the spares, as he rushed off to chase the teen and his Imagin partner.

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

Nekos sat down on the sands of time, looking out at the watery beach in front of her. "Isn't this a beautiful sight? All that has been, is, and will be all convene here in this sand."

Her host, the young woman with brown hair, rolled her eyes. "Let's not forget, cat, that you promised to help me find the diamond."

The Imagin looked over at the woman and smiled with a Cheshire Cat-esque grin. "No worries, ma cherie, I shall be able to help you steal that sacred artifact soon. However, let's just enjoy the serenity here."

"Get over here, you Cat-jerk!" Momotaros yelled, flying over a sand dune on the DenBird as Den-O and landing in front of the two.

"You! You're that purple armored warrior, aren't you?" Nekos recalled.

"We're Kamen Rider Den-O!" Eric stated, "And we're about to kick your feline butt!"

"Well, my pêche rouge, I'd love to stay and chat, but I have a little something to do," Nekos replied, "Au revoir!"

"Stop speaking a language I don't understand!" shouted Momo, charging toward Nekos. However, when he got to her, she flip kicked him up and Den-O fell into the temporal sea.

Nekos and the woman were about to take their leave, when Kotaro on his DenBird came into view as Kotaro jumped into the fray as New Den-O. He then snapped his fingers twice and called out subtley "Teddy," in which Teddy then appeared in his hand in sword form.

Meanwhile, Momotaros was having a hard time keeping Den-O afloat. "Help! I can't swim!"

Suddenly, Urataros's voice appeared in Den-O's mind. "Mind if I help out?"

"We don't need your help, Turtle!" Momo retorted, "I am doing just fine on my own,"

"Says the Imagin who can't swim," commented Eric with some snarkiness in his voice, "Urataros, go ahead and help us out."

"Nani?!" Momo shouted. Then, the Imagin was forced out of Eric's body as Ura entered. Den-O's armor suddenly changed from red to blue, and looked more turtle-like.

Den-O then swam to where Kotaro and Nekos were fighting, while at the same time placing the pieces of the DenGasher together to form a staff that extended outwards. When he reached shore, he stood toward Nekos pointing his finger at her and the other hand held the Rod DenGasher. "Mind if I reel you in?" Den-O asked in the smooth voice of Urataros.

"Seriously, dude? That was pretty lame," Eric stated.

"Do I complain about what you say?" Urataros retorted. With that, Den-O charged forward with his staff and attacked Nekos. The two riders swung at the Imagin with their weapons, but Nekos blocked with her claws and slashed at the two.

"This is a waste of time. You can't even think of beating me," Nekos chuckled.

"We'll see about that," Eric replied, as Den-O placed his rider pass to his belt, activating full charge. Suddenly, a line of energy emerged from the DenGasher. With that, Den-O swung the energy whip around Nekos, catching her in the line.

In synchronicity, Ura and Eric shouted "Den-Rod Liner Smash!" and flipped Nekos over Den-O's head toward the ground. However, Nekos disappeared at the last second and possessed her host.

"Good try, boys, but not good enough to beat me. Now then, my host Katherine and I must take our leave. Try to follow us if you can."

With that, Nekos disappeared, likely into the time stream. Kotaro and Eric's armor dissolved and turned into their human forms.

"Well, how are we going to find him now?" Eric asked.

"They probably left some temporal essence here that could tell us when they have gone," Kotaro deduced. He then held his Rider Pass into the air, and a ticket appeared inside of the case. The numbers read 6, 20, and 2011.

"We'll have to find them fast, before whatever they do to the timestream has massive consequences."

In the nightlight of New York City, Nekos looked down upon the building where she and her host were about to pull a really massive heist.

"Here we go," she stated. With that, she jumped off the rooftop and used her clawed gloves to grab onto the wall. She then began to scale the wall up to a window, which she used her gloves to make a hole big enough for her to slip through. After silently taking out the guards and disabling the alarms, Nekos moved toward an object in the center of the building. It was a sparkling white diamond that sat on a tall wooden pedestal.

"Jackpot!" she grinned, grabbing the diamond without fear of alarms ringing in the building. She was about to take her leave, when a golden warrior holding a large axe jumped from the nearby building, nearly cleaving Nekos and Kat in half.

"My strength has made you cry…" the golden warrior, who was Den-O's Axe Form, stated.

"You?! What are you doing here?!" Nekos shouted.

"We followed your temporal trail all the way here," New Den-O stated smugly.

"Alright! Now it's time to finish this!" Eric shouted from inside Den-O.

Den-O then sliced at Nekos, who dodged. While she was in Kat's body, the imagin made her host incredibly agile.

"You'll have to do more than that to beat me, Mon Amie."

Den-O then placed his rider pass to his belt, and activated Full Charge. He then jumped into the air and brought his axe down upon the Imagin, shouting "Dynamic Chop!"

At the last second, Kat and Nekos split from each other and dodged the attack. Nekos then moved towards her host, holding the diamond, and gave it to her. "I have obtained what you wanted. Now, you give me what I need."

Kat fell to her knees, finding it hard to speak. "I… I did it. The memories… coming back…" She then split in half to become a time portal. Nekos walked towards it, when she felt a shot to her back.

"We aren't letting you go any further!" Ryutaros shouted. In that instant, Den-O had changed into his Gun Form. He ran toward Nekos, changing into sword form, and sliced her with the DenGasher. Den-O then started to change rapidly between forms, as if there were three Den-Os in each of the melee forms striking the Imagin in succession. He then did a backflip, and activated full charge with Gun Form.

"Kamen Den-Shot!" Den-O shouted, sending an immense blast of energy into Nekos.

"Impressive, but I must take my leave. Farewell, Kamen Rider Den-O. I hope to see you again soon." With that, Nekos backed up into the portal and cackled, disappearing into the portal just as it closed, followed by the blast hitting the wall. Soon after, Katherine reappeared in front of them.

"Drat! Where did she go?" Eric asked as he changed into normal.

Kotaro walked up to the young woman. "Where did you send her?"

Katherine looked up to him with tears in her eyes and smiled. "The pain… it will be over. The future… it shall be changed."

"Where did she go?!" Kotaro demanded.

Suddenly, Katherine dissolved into sand. The world suddenly began to shift around them. Next thing they knew, they were outside the building. It hadn't been broken into! The future hadn't been changed.

"Does stuff like that always happen?" Eric asked.

Kotaro looked around the area, concerned. "This could be bad. We don't know where that cat Imagin has gone. She could cause irreperable damage to the future. This is really bad."

Teddy put his hand on Kotaro's shoulder. Kotaro looked at his partner and smiled, as the heroes returned to the DenLiner.

Onboard the time train, Vivian ate some ramen noodles that Naomi had whipped up for her. She always had a liking for Japanese food like that, despite the fact that she was not of Asian descent at all. Eric sat back next to Kotaro, as the young man explained to Owner the situation.

"Man, I bet I could have beaten that cat all by myself if I was in direct control. All these Imagin would fall to me if I were in full control."

Momotaros glared at him. "Good luck trying to get access to your weapons then, kid."

"You know, Eric, you remind me of myself when I was younger," Kotaro stated, "I was once cocky and arrogent, and thought that I could take on the world all by myself. However…" he paused, then looked over at Teddy, as it was thanks to his friend that he was able to fight all these Imagin, "After getting my hind beat and almost losing my friend and partner, I realized… strength and skill alone cannot win the battle. I guess on that day, I found what my grandfather's true strength was… his spirit. His humble and selfless nature is what I truly needed. That is why I now lead the Den-O team across time to defend those who need help.

"That… is what makes a true Kamen Rider." Kotaro then held out his hand to Eric, who stared at it with wonder.

"That… is what it means?" Eric wondered.

"No matter what, you'll always have your team by your side," Urataros stated.

"We're with you, Eric," Kin added.

"There's a reason why I chose you, Eric. You have a heart of gold, and are willing to help those in need," Momo said.

With that, Eric smiled. "Thanks, you guys. No matter what, let's aim for a better future!"

"Alright!" Ryu cheered.

In August 6th, 2009, a 17 year old girl ran through a burning house looking for her parents. "Mother! Father!" she shouted. She reached her parents' room, seeing them asleep in their bed, unaware of what was happening. The girl shouted for them, but it was no use.

Suddenly, something began controlling her body. An orange cat-like tail sprouted between her legs, and she grew cat ears on her head. She then jumped into the flames, grabbing her parents and bringing them safely outside unharmed. Her tail and cat ears suddenly disappeared, and a cat-like humanoid stood near her.

"Who… who are you?" she asked.

The cat looked at the girl and smiled slightly, then held out her hand to help her up. "A friend. Now then, I must go to find something in this time. Would you like to come with me?"

"But… my parents…"

"They'll be safer here. Now then, shall we get going?"

The girl smiled, and followed the cat. As she looked behind, she saw her mother waking up. "Katherine? What happened? Where are you going?"

"Don't worry, Mom. You're safe now, but there's something that I must do right now…"

Notes: Hooray! Finally added in the Den-O theme to this part! I've realized that It wouldn't be Kamen Rider Den-O w/o the theme song. I might go back and add it in later. Y'know, I initially thought of adding the lyrics to the Den-O theme after reading some of Kamen Keyblade Duelist's fanfics, so props to you, KKD. You're a pretty awesome writer.

Anyways, story-wise, I think this episode went well. However, I find it hard to understand Nekos's true intentions. Is she good? Or is she evil? Only I know, and you'll have to find out. X3 Anywho, tune in next time.
