Ryotaro Nogami sighed dejectedly as he walked home. Now at the age of twenty, he was hoping to enter Tokyo University. However he had failed the exam. He thought that going back to high school and finishing his final year would prepare him for the entrance exam but it was all for naught.

"What to do?" Ryotaro asked himself.

'Ryotaro, why so glum?' asked Urataros.

"I failed, Urataros," said Ryotaro.

'Now, don't give up. Whatever happened to that young man who saved the world?'

'Oi, Ryotaro! Just keep on trying!' another voice spoke in his head.

"Thank you, Momotaros," Ryotaro smiled.

'Persevere, Ryotaro,' spoke another voice.

"I will, Kintaros," replied Ryotaro.

'Hey, let's go and see Onee-chan, OK?' a childish voice asked.

Ryotaro grimaced at the thought of facing his sister. Ryotaro had moved out of the Milk Dipper after Sakurai Yuuto had returned. Ryotaro didn't mean the younger incarnation. He meant the man who was now his sister's husband. They were also expecting a child soon and Ryotaro knew who that child would be.

Suddenly, he heard a loud shout.

"Please, get out of the way!!!"

Ryotaro followed the source of the voice and looked up to see a girl falling. "EH!!!???"

"Please get out of the way!!!"

WHAM!

She fell right on top of him. It seemed Ryotaro's luck hadn't changed. He then found himself staring at her backside and he blushed.

"Ow…" the girl groaned as she crawled off him. "I must've jumped too high." She then turned to look at Ryotaro. "Thank you for saving me."

Ryotaro looked at the girl. She had dark brown hair pulled into a ponytail and wearing a white kimono top with a short pink skirt, white thigh high socks with black boots and red combat gloves.

'Wow, she's cute,' said Urataros.

"You're…welcome," replied Ryotaro. After fighting the Imagin for over a year, Ryotaro could take the unusual events around him in stride.

She smiled. Suddenly, she shoved him backwards. "Watch out!" Her breasts landed on his face for a moment and bounced off him just as a bolt of lightning came crashing down on the spot they had been sitting on before.

"Nani!?" Ryotaro yelped.

"There's no use running!" Ryotaro heard and he looked up to see two women in matching S&M standing on a rooftop. One was dressed in red and the other was in purple, but judging by their identical looks they were obviously twins. "Fight with us."

"I don't want to fight yet!" the girl Ryotaro just met said.

"Even if you don't want to fight…we'll make you!!!" the twins jumped off the roof, hands crackling with energy.

"We have to run!" the girl said as she grabbed Ryotaro's arm but she met with resistance. "Huh?" She looked to the young man and saw that his hair was now in a ponytail with a yellow streak. "What are you doing?" He tugged his arm out of her grip.

K-Ryotaro popped his neck to the side and said, "We must face all challenges head on!" The lightning bolts missed him as the girl leapt back.

"Oh, so the man wants to fight," one of the women said.

Her twin added, "Move out of the way."

Suddenly, Ryotaro changed again and now had a blue streak in his hair as his eyes turned blue with glasses over his eyes. "I'm sorry, but I cannot let a young woman be harmed. You both may be pretty, but I can't allow any harm to come to this girl," said U-Ryotaro.

"Listen! You have no idea what you're dealing with!" one of the leaher-clad women spoke. That was when Ryotaro's look changed as the glasses vanished and a cap appeared on his head with a streak of purple hair falling at the side of his head.

"Hey, are you strong? I don't hear an answer!" R-Ryotaro spoke in his childish voice.

"Get out of our way!" the twins demanded.

Now Ryotaro's hair was spiked up with a red streak and he said, "I can't do that! It's been awhile since I've had a good fight! Now, let me tell you this; from the beginning to the end I am at my climax!"

He took out the Den-O belt and strapped it on. The three women looked at him curiously as he took out a rail pass and pressed the red button on the belt. The belt released a musical tune as he called, "Henshin!" before swiping the pass over the belt.

"Sword Form!"

Transparent shards enveloped his body, much to the women's surprise, before forming a black bodysuit with silver boots and white gauntlets. The torso was covered by black armor with a silver stripe running down the middle. His helmet was white with a silver mouthuard, large black eyes and a silver stripe running down the middle as well. After that additional armor appeared. The armor that attached to his back was black with yellow trimmings and the armor attaching to his chest was red, still with the silver stripe. He had broad shoulder armor attached to the shoulders. Finally, a red metal peach slid down his helmet and attached to his faceplate before it split with the tips extending.

"Ore…Futatabi Sanjou!" Den-O (Sword Form) announced as he was transformed.

The girl Ryotaro had saved exclaimed, "Sugoi!"

"What is this!?" one of the twins questioned. Her twin could only respond with silence.

"Alright, you bitches," Den-O began, "If it's a fight you want then I'll give you a fight. Ikuze, ikuze, ikuze!" He charged at them and the two women sent bolts of lightning flying at him. They struck him in the chest, sending him flying. "Itai…Oi, that wasn't fair!"

"Hmph, he's weak," said one of the twins.

"Well, we better deal with him first before going after that unwinged one," said her sister.

"Kuso…" Den-O cursed as he rose to his feet.

'Momotaros, are you alright?'

"I'm fine, Ryotaro," Den-O answered. "But these bitches are going down!" He began to assemble his DenGasher and the blade extended. "Now, time for my hissatsu attack!"

'So soon?' Ryotaro asked.

Den-O ignored Ryotaro as he swiped the Rider Pass over his belt buckle.

"Full Charge!" the belt announced.

"Hissatsu!" began Den-O as energy transferred from his belt into his sword. The blade glowed. "Ore no Hissatsu Waza! Part 2!" The blade detached from the DenGasher, connected only by red electricity, and Den-O swung at the twins who saw the blade coming. They leapt out of the way of the attack but Den-O continued to swing at them. "Take this!!!" The blade came crashing down but missed. "Hey, where did they go!?"

'Forget about them, Momotaros. We need to check on the girl,' said Ryotaro.

"OK." Den-O removed his belt and the armor vanished. Ryotaro regained control of his body and looked to the girl he'd rescue. He approached her and asked, "Are you-Urk!"

"Oh, thank you! Thank you!" she said gratefully as she hugged the stuffing out of him. "You drove them away! You're truly my savior!"

"It was nothing," said Ryotaro.

"What's your name?" she asked.

"I'm…Ryotaro Nogami."

"Oh, I'm Musubi!"

"Nice to meet you, Musubi-san."

"How did you do all that?" she asked. "How did you get that cool armor and that sword? How did you learn to fight?" Her tummy rumbled. "Oh…I'm hungry." She looked like she was close to passing out.

"Let me treat you to something to eat," said Ryotaro.

------------------------------------------------

Ryotaro went to McDonalds and got some food for the girl. He took his order to go and now was sitting on a park bench with Musubi who was eating two burgers at once, alternating between the two she was holding in her hands.

"Oh, thank you so much! You're a lifesaver!" she said.

"You're welcome…" answered Ryotaro.

'Oi, Ryotaro! Ask her about those two bitches!' demanded Momotaros.

"Ano…who were those women and why were they after you?" Ryotaro asked.

"Well…it's because I'm an unwinged Sekirei," she said.

"Sekirei?" Ryotaro blinked. She then gazed at him. "Huh?"

"I wish someone like you was my Ashikabi…"

"Ashi…kabi…?"

Musubi then remembered what she had wanted to ask about. "So, can you tell me where you got that armor?"

"It's…a long story," said Ryotaro.

'That's putting it mildly, Ryotaro. How about I be the one to tell the young lady?'

'Oi, shove off you perverted turtle!' Momotaros exclaimed.

"Well, well, well, look what we've found," a familiar voice spoke. Ryotaro gasped when he saw the S&M twins again.

"Oh, no!" Ryotaro cried.

"You may have surprised us before, but this time we won't give you a chance to do that trick again!" one of them said.

Ryotaro grabbed Musubi's hand. "Hurry, we have to run!" He dragged her along as they fled from the two women whose hands were crackling with electricity.

"There's nowhere to run!" the shouted after Ryotaro and Musubi.

As they ran, Ryotaro said to Musubi, "I'll slow them down while you run!"

"But, Ryotaro-san," she argued.

"Please!" He let her go. "Go! Go now!" He stood in the twin's path as Musubi ran. She did look back. "Leave her alone!"

"You're not her Ashikabi," said the twin in red. "Why are you protecting her."

"I don't know anything about Sekirei or Ashikabi," said Ryotaro, "But I'm not letting you hurt her!" He took out his belt but he dropped it when the woman in purple shot a lightning bolt at his hand. "Itai!"

"Sorry, but no more tricks," they said. Ryotaro grimaced. He ignored his belt and ran away as the twins gave chase, thinking he would lead them to Musubi.

Ryotaro ran in front of an alley but someone grabbed him and pulled him in. He was shoved against the wall. He was about to yell when he felt a hand cover his mouth and a pair of breasts pressed against his chest. 'Musubi-san?'

"Please, be quiet, Ryotaro-san," said Musubi. He gave a nod. Of course the twins had seen him getting pulled inside and went into the alley.

"Nowhere to run," the one in red said.

"Just give up, it's pointless," said the one in purple.

Musubi glared but her heart began to pound in her chest. She turned her eyes to Ryotaro and said, "It's you…" She removed her hand from his mouth. "You're the one." Without warning, she kissed him.

"No! She found her Ashikabi!!!" the twins cried.

Suddenly, pink light exploded from Musubi and formed a pair of wings. Ryotaro was amazed by the display. "Su…sugoi…"

"Thank you, Ryotaro-san," said Musubi gratefully.

"Che, looks like you've found your Ashikabi," said the red twin, Hibiki, with her hand crackling with electricity.

"It won't change a thing," said the purple twin, Hikari, her hand crackling with electricity too.

"Ryotaro-san, let me protect you now," said Musubi.

Ryotaro was about to open his mouth when all of a sudden his Den-O Belt formed around his waist. "Huh?"

'Ryotaro, let's fight! Together!' said Momotaros.

Ryotaro reached into his pocket and pulled out the Climax Cellphone K-Taros. He looked between Hikari and Hibiki who had their attention focused on Musubi. "Boku-tachi ikuyo." He pressed 3-6-9-# on the phone.

"Momo-Ura-Kin-Ryu!" the phone spoke. He pressed a button on the side of the phone. "Climax Form!" He attached the phone to his belt.

Musubi, Hikari and Hibiki turned their attention towards Ryotaro who began to transform again. They then saw masks fly around him as his armor formed. His torso armor changed, with a circle on his chest and train tacks in the centre of the circle as well as his shoulders, arms and legs. A yellow mask with a horn in the centre attached to his left shoulder as a blue one with orange eyes and a pair of horns attached to his right shoulder. A purple mask that resembled a dragon's face attached to his chest and finally the peach shaped mask appeared on his faceplate before it became 'peeled'.

"Ore-tachi…Sanjou!" Den-O announced as he was transformed into Climax Form.

"Ashikabi-sama!" Musubi squealed. He looked so cool. "Sugoi!"

"Stop showing off!!!" shouted Hikari as she sent a bolt of lightning at Den-O who ducked out of the way. He then charged towards her and rammed his fist across his face.

"Take that, you S&M bitch!" Den-O shouted.

"Hikari!" Hibiki went to help her twin but Musubi got in her way.

"Your opponent is me," said Musubi.

"That suits me just fine," growled Hibiki.

------------------------------------------------

OK, whaddya think? The first Kamen Rider Den-O/Sekirei crossover. Sorry it had to end here but I wanted to take the time to watch the anime first and maybe read the manga for more ideas.
