Ryotaro watched as Musubi and Yomi fought with the two Sekirei fighting violently. Despite the tip of her scythe being broken off, she could still cause considerable damage to Musubi due to the vacuum blades she could launch at the brunette Sekirei. A blast of vacuum blades actually tore of Musubi's top, leaving her topless. Ryotaro blushed as he saw this.

Yomi laughed, "Wow, you look really nice! You love giving your pervert of an Ashikabi a show, huh?"

"Someone like you will never understand Ryotaro-sama," said Musubi.

"What is there to understand?" Yomi sneered. "He's weak and useless. A pathetic little man. He can do nothing but watch as I eliminate you!" Yomi swung her scythe at Musubi but Musubi jumped and kicked her in the face. Snarling, Yomi exclaimed, "You'll pay for that!!!"

As Ryotaro held the sleeping Kusano, he frowned as he watched Musubi fought. He then called for help, "Sieg, take care of Ku-chan for me." A white haze of energy flew out of Ryotaro and then reformed into the Swan Imagin known as Sieg.

"Let me take care of the little princess, Ryotaro," said Sieg as he took Kusano into his arms and held her protectively. "Do what you must?"

Ryotaro nodded and he stood up. The Den-O belt appeared and equipped to the buckle was the K-Taros. The DenKamen Sword also appeared in his hand as he narrowed his eyes. He took the Den-O Pass out from his pocket and said, "Musubi-san, let me help you!"

"Ryotaro-sama!" gasped Musubi.

"Huh?" Yomi cocked an eyebrow. "What are you going to do with that toy?"

"This," said Ryotaro as he inserted the Den-O pass into the back of the DenKamen Sword's blade. "Henshin."

The sword called out, "Liner Form!"

Yomi watched as a suit of black and white armor enveloped Ryotaro when all of a sudden a ghost train appeared. It raced towards Ryotaro but since it was intangible it passed right through Ryotaro without harm. His armor began to change. His boots became red as did his bodysuit as the red color rose up his legs, leaving the sides black. The sleeves and gauntlets also changed, becoming black on the inner side, white on the outer side, with a red line running in between the black and white sides. New armor formed. It was mostly white with yellow headlights on the chest and some back and red accents which were also present on the broad shoulders. Finally, to complete the change, a T-shaped antenna rose and set on the top of his helmet as a pair of triangular eyes fit upon his faceplate with yellow, blue and purple spikes on the sides of the eyes.

Ryotaro had become Den-O Liner Form.

"Musubi-san, let me handle this," said Den-O as he strode towards Yomi who was stunned by the sudden transformation.

"What sort of Ashikabi are you!?" she demanded.

"The Masked Ashikabi," he answered and then he swung his sword at her. She blocked with the shaft of her scythe and sparks flew as the weapons collided. They continued to swing at each other and their weapons clashed. Musubi watched, amazed, as her Ashikabi handled himself against another Sekirei.

Seo, Hikari and Hibiki watched the fight and Seo whistled, "Wow, now that kid really has some very interesting skills." He never expected Ryotaro to have any tricks up his sleeve but now he knew better.

Den-O himself was trying not to harm Yomi. Defeating an Imagin was easy but fighting Sekirei was harder. He didn't want to kill any of them since they looked so human. But, he had to fight. He had to protect Kusano and Musubi.

He pulled the Delta Lever and the masks spun.

"Ura Rod!"

He pulled again.

"Kin Axe!"

And once more.

"Ryu Gun!"

He adopted Ryutaros' fancy dance moves as he dodged Yomi's swings. "Stand still!" she shouted, trying to land a strike but he was far too agile as he dodged. He then closed the gap between them and bashed her hard with the turntable hilt of his weapon, sending her crashing to the ground.

"Momo Sword!"

He pushed in the Delta Lever and the symbol in the centre of the hilt turned green. A red AuraLiner resembling DenLiner Gouka appeared around him as the golden energy tracks appeared under his feet. He rushed towards Yomi who could only shout in shock as he called, "Densha Giri!"

It was a killing move but this time Den-O used the flat side of his sword to execute the attack, striking Yomi violently and sending her flying. However, this managed to rip off all her clothes and expose her Sekirei crest.

Musubi swiftly took advantage of this and chanted her norito as she touched the crest, "Fist of my contract, destroy the calamity of my Ashikabi!" In a flash of pink light Yomi's crest vanished and before long she was unconscious.

Den-O wondered what Musubi had done but then turned his attention towards Sieg who was holding a sleeping Kusano. "Thank goodness." He turned to Musubi who was covering her naked breasts with her arms and he blushed under his helmet. "Musubi-san, you're alright."

"Yes, and you were amazing as well," said Musubi as she smiled to Den-O.

Seo sighed. "Let's go," he said to Hibiki and Hikari before they left the scene.

"Alright, let's take Ku-chan home," said Den-O.

"I'm afraid I can't allow that," spoke a mysterious and stoic voice and Den-O spun around to see a familiar figure which also made Musubi gasp.

It was Den-O Sword Form but all the red parts of his armor were purple and decorated with black tribal markings which also decorated his gauntlets. He was holding the DenGasher in his hand and looked like he was ready to fight.

It was Nega Den-O!

"What?" Den-O gawked. "Negataros?"

"Give me No. 108 you damn Ashikabi," demanded Nega Den-O.

Den-O looked to Kusano and then back at Nega Den-O before shaking his head. "I…I can't do that!"

"Why not?"

"She was calling to me! I'm not going to abandon her."

"Then…you leave me no choice!" Nega Den-O charged at Den-O, forcing Den-O to raise his sword to block Nega Den-O's attacks.
