Shoutarou speaking

As Kamen Rider Mar:

Shou speaking

Philip arrived back at the Narumi Agency and saw Shoutarou and Akiko sitting down. Shoutarou had a stern look on his face.

"Is something the matter?" Philip asked.

Shoutarou faced Philip and stood up. "Where were you? You couldn't have taken that long to bring Sozoka back to her house. Did she ask anything? Did you find a way to explain what she saw?"

Philip nodded, taking in the questions calmly. "I told her the truth," he stated casually.

"What!" both Shoutarou and Akiko exclaimed.

"Why would you do that?" Shoutarou asked.

"I believe I've read that you should not keep any secrets from someone that you're dating," Philip replied.

"'Dating'!" Shoutarou was speechless. However Akiko got up and was happily smiling. "That's so wonderful!"

Philip blushed. He faced Shoutarou. "This is the first time I felt like this towards anyone. Please, can you support this?"

Shoutarou sighed. "As long as it won't interfere with our investigation."

Philip smiled. "Thank you."

Shoutarou got his fedora. "I'll be going out. See if I can find any more information on Shou's whereabouts. Try to do a look-up about why these Dopants are attacking." He then left.

"Well to work then." Philip remarked.

A/N: The following events will be split into three points of view.

Shoutarou's POV:

Shoutarou rode out and headed for the Futo station, wondering if Terui was okay and if he found anything yet. Before he arrived though, something got in his way and he pulled his brakes. "Hey, watch where your-" Shoutarou started, but stopped when he realized he was looking right at Adauchi Shou.

"Hidari Shoutarou," Shou said. "I hear you've been looking for me." Shoutarou prepared to pull out his Driver. "I wouldn't do that if I were you, not now anyway."

"And why should I listen to you?" Shoutarou was ready to transform.

"Because if you don't, I can't be liable to the number of people that will be killed from the Dopants I'll release," Shou said with a smile.

Shoutarou growled and he kept his Driver.

"Good," Shou said. "Now, meet me at the Futo Tower in one hour so we can have a proper battle." Shou then turned around and before he left, he looked back and added, "Come alone." He dropped a smoke bomb and disappeared.

Shoutarou pounded his fist on his bike. He then got a call from Philip. "What?"

"Shoutarou, I think I found something about the Dopant attacks," Philip said. "Get back as soon as you can." He hung up after.

Shoutarou looked at the time. "I still have an hour," he thought before he drove back.

Shoutarou arrived back and entered the hangar. He saw Philip drawing a map of Futo on the board. "What did you have to show me Philip?" he asked after removing his fedora and sat down.

Philip turned around."I think I found a connection between the attacks." He encircled three areas on the map. He pointed at one. "This was where Terui Ryuu faced the Triceratops Dopant." He then pointed at another circle. "This was where we fought the Gene, Nightmare, and Old Dopants." He pointed at the final circle. "And this was where we defeated the Violence and Beast Dopants." Philip connected the three locations, forming an incomplete square. "All the points are equidistant from each other. If my calculations are correct, then, Adauchi Shou will send another Dopant...here." Philip then encircled Futo Tower.

Shoutarou flinched and remembered what Shou said. "Now, meet me at Futo Tower in one hour so we can have a proper battle." His face then turned grim. "We have a problem then." Shoutarou then told Philip and Akiko about Shou's challenge.

"You're not really going are you! It's obviously a trap!" Akiko said.

"Akiko is right. You'll be walking into Shou's trap," Philip agreed.

"If I don't, then Shou will send another Dopant to attack the city. At least this way, no one else will get hurt." Shoutarou stood up and put his fedora back on. "You could either agree to help or stop me. It's your choice."

Philip sighed. "Very well then. Just be careful."

Shoutarou grinned. "Of course. After all..." He held up the Double Driver. "I'll have you with me." He then left.

Sozoka patiently waited outside the Narumi Agency. She held up her binoculars and saw Shoutarou getting on his bike and leaving. She pulled out her cellphone and called her brother. "He just left."

"Good," Shou replied from the other line. "You know what to do." He quickly hung up after.

Sozoka walked to the door of the agency, put on a fake smile, and knocked on the door.

Shoutarou parked his bike as he arrived at the Futo Tower. He looked up at the structure before he entered. As he arrived at the top floor, he stepped out and saw Shou standing across him.

"So, you finally arrived," Shou amusingly said.

"You can stop your games and just get to the point," Shoutarou shouted. "Why did you want me here?"

Shou grinned. "Oh right." He pulled out his Mar Driver and attached it to waist. "It's time we finish things between us, don't you think?"

Shoutarou pulled out Double Driver. "I don't think you brought me out here just so that we could just fight."

"Of course not," Shou said. "I want to see how you can fight without your partner."

Shoutarou was confused at what Shou said. "What are you talking about?"

Shou grinned. "Just try and transform. You'll see."

Shoutarou put on his Double Driver. However, he sensed that something was wrong. "Hey, Philip." Shoutarou tried calling Philip through their link from the Driver, but there was no reply. Shoutarou removed the Double Driver. "What did you do to Philip!"

"My partner took care of him." Shou gave a soft chuckle. "Now it will just be you by yourself." Shou put on his Mar Driver and the Smog Memory was already in place. He took out his Ace Memory and pressed it. "ACE!"

"Henshin!" He inserted the Memory under the Driver and opened it. Dark wind surrounded Shou and he transformed into Kamen Rider Mar. "Now, count down to your end."

Terui's POV:

Terui arrived back at the Futo police station after the encounter with the Brain Dopant. His body was still in pain from the fight, but he knew that he had to confirm his suspicions.

He entered the coroner's office and saw Sai working. "Sai."

Sai turned around, surprised. "Superintendent, what are you doing back here?"

"I think you know why." Terui threw on the table the scalpel that the Brain Dopant dropped.

"What is that?" Sai asked.

"This is a scalpel that a Dopant dropped," Terui said, the tone of his voice serious. "But you would know that, since you dropped it."

Sai was shocked. "Superintendent! Are you accusing me of being a Dopant? You don't have any proof that I'm a Dopant."

"I know that you make your own medical equipment. I also know that you mark your initials on all of them." Terui pointed at the scalpel.

Sai picked up the scalpel and gave a horrified look when he saw his initials, K.S. He stayed silent for a few moments, then he gave a chuckle, which soon grew into maniacal laughter. "Very perceptive, Superintendent."

Suddenly, he threw the scalpel, aiming for Terui's face. Terui quickly reacted and dodged the blade, but he saw that Sai escaped through the back exit. Terui ran after him and saw him standing around the containers where the corpses are kept.

"You should have stayed away," Sai said. "Now, it seems that I'll have to take care of you first." He pulled out his Gaia Memory and pressed it. "BRAIN!" He then inserted it into the crown of his head. Sai transformed into the Brain Dopant, his attire changing into the blood streaked lab coat, his hands turning into the sharp claw and large scalpel, and finally, his head changed into the purple brain with its single eye.

Terui pulled out his Accel Driver and prepared to transform, however...

"I won't give you the chance to transform." Brain's eye glowed. Suddenly, the body containers started rattling and they opened. The corpses started crawling out and headed towards Terui. "Enjoy." He then took his leave.

"Damn it!" Terui put on his Driver and pressed his Memory. "ACCEL!"

"Hen...shin!" He inserted the Memory into the Driver and revved the handlebar. "ACCEL!" As he transformed, the energy surrounding him blasted the corpses back. He punched some corpses, causing them to fall back, but more of them just got back up. Accel knew that he could not damage any of the bodies since they were being used in investigations and their sheer numbers would overwhelm him soon. He then decided to transform into his Bike Mode and rammed through the remaining corpses. After he escaped, he locked the exit, trapping the corpses inside.

"Now to find Sai."

Philip's POV:

Philip opened the door and saw that it was Sozoka. "Sozoka, what are you doing here?"

"I just wanted to see you again." Sozoka smiled.

Philip blushed. "Thank you. Come in."

Sozoka then stepped inside. "Are you alone?"

"No. Akiko is here as well." Philip answered.

Sozoka faced him. "Oh. Can you ask her to leave for a while? I want to talk with you alone."

"I'm sorry," Philip said. "But we're working on a case right now. Maybe we can talk later."

Sozoka turned away from him and, for a few moments, said nothing.

"Sozoka?" Philip tried to see what was wrong.

Then Akiko came out of the hangar. "Philip-kun. What's taking so-" Suddenly Akiko collapsed to the ground.

"Akiko!" Philip rushed to Akiko and saw a tranquilizer dart on her neck. He then turned around and saw Sozoka with a gun in her hand. "What did you do?"

"Don't worry," Sozoka said, her voice now cold. "I just put her to sleep. It would have been much easier if you followed what I said."

"Why did you do this Sozoka?" Philip asked, not understanding why this happened.

"For my brother's revenge." Sozoka pointed the gun at Philip.

"Your brother...?" Philip then came to a realization. "Your brother is Adauchi Shou!"

"Very good. Onii-san said that you would be smart. Now get up." Sozoka ordered.

Philip slowly got up. "What do you want? If you wanted me dead, you could have killed me already."

Sozoka grinned. "Oh no. Onii-san has something much better planned. But first, I'll let my associate take care of you. As for me," She pulled out the Mar Driver and attached it to her waist.

Philip's eyes widened. "It can't be. Your-"

"That's right." Sozoka pulled out her Memory and pressed it. "SMOG!"

"Henshin!" She inserted the Memory and it disappeared as she collapsed to the ground.

"I need to get out of here." Philip said as he picked up Akiko. However, something was thrown at his neck and it entered his body. Philip yelled in pain as he collapsed to the floor. "I can't...move." He then passed out soon after.

The Brain Dopant entered the office "Now for the plan to take place." However, before he could get close to Philip, the Fang Memory appeared and attacked him. "Annoying pest!" He used his claw and knocked Fang across the room, damaging it down and now unable to get up.

Brain then picked up Philip and Sozoka's unconscious bodies and walked out, leaving an unconscious Akiko and a damaged Fang.

Shoutarou took a step back as Mar took a step forward.

"Don't even think about running. I can kill you as fast as you turn around. Now be good and just wait to die."

Shoutarou grunted. "Don't think I'll go down so easily."

Mar laughed. "What could you possibly do? I've taken care of your partner, so you can't even transform."

Shoutarou smirked at Mar. "Philip isn't the only way I can transform." He pulled out the Lost Driver and attached it to his waist."

"What?" Mar was confused at what Shoutarou was doing."

Shoutarou pulled out his Joker Memory and pressed it. "JOKER!"

"Henshin!" Shoutarou inserted it into the slot and opened the Driver. "JOKER!" Purple energy surrounded him as armor formed over his body transforming him into a full black version of Double.

"Impossible!" Mar shouted, enraged.

"This is the other Kamen Rider that protects Futo," Shoutarou said. "Kamen Rider...Joker!"

Joker and Mar stared at each other, preparing to fight, as the winds of Futo blew around them.
