Hard-Boiled of the League

'America, so many mysteries here. Perfect for a hard-boiled detective like myself.' Shotaro Hidari thought as he looked on at the landscape of America's Windy City, Chicago from the window of his new office. He was completely unaware of the danger inch closer and closer till...

BONK!

"OW!" he said as he turned to the one who hit him. It was his so-called chief Akiko Narumi.

"What did you hit me for?" he asked.

"You were staring out into space. Besides Phillip's done researching and now wants to experience 'Chicago Style Pizza'." Akiko said waving her 'Green Slipper of Doom'.

"Fine fine." Shotaro said as he and Akiko went to go get Shotaro's partner Phillip.

Hours later after Shotaro was reading the newspaper while Akiko and Phillip were watching a movie and eating pizza. Shoatro was scanning the paper for any Dopant sightings. With the high-ups of the organization defeated, the few remaining Gaia Memory dealers took what memories that they didn't sell or weren't destroyed and took them to America which prompted the detectives to chase after them.

A scream shook Shotaro from his thoughts as he turned towards his companions. "What now?!"

"Shotaro, there are aliens attacking Earth." Akiko said as Shotaro stood and walked over to where they were sitting.

"You sure it's not just part of the movie?" Shotaro asked just as he looked at the tv screen.

"It's a live newscast from Metropolis Shotaro." Phillip said as the report showed strange-looking 3 legged walkers attacking the army.

"Are we sure that this isn't some sort of Dopant ability or something?" Shotaro asked in which Phillip quickly replied "Actually I'm not sure. Let me do a look up."

Phillip then went to the Gaia Library but as soon as he got there he was bombarded with images which quickly stopped leaving Phillip alone in the Gaia Library.

"What was that?" Phillip asked himself as he went back to do his look up.

A few minutes later the images reappeared but this time Phillip was ready. Quickly analyzing the images Phillip had gotten several keywords ready in which he would use to find out where the images were coming from as well figure out that whoever sent them had insight on the so called aliens.

"We're looking for the name of the person sending these images and his location." Phillip said as he stood in front of the bookcases starting a new look up.

"First Keyword: Telepath." Phillip said when he realized that these were images sent by someone's mind.

Most of the bookshelves disappeared yet there were still a few remaining.

"Second Keyword: Non-Human." Phillip said as he come somehow tell that the one sending the image wasn't human.

Now stood only one bookcase left with some books on it.

Final Keyword: Prisoner." Phillip said when he saw that the images that they were a little distorted like the one sending them was being blocked or something like that.

This time there was only one book remaining with the words "Name and Location" on the front.

Phillip grabbed the book and looked inside. "So that's who's sending those images. Better go see what he knows about what's going on." Phillip said just before he exited the Gaia Library.

"We have to go Shotaro." Phillip said as he moved a bookcase revealing a door. He opened the door and entered a hidden elevator with Shotaro and Akiko right behind him.

"Go where?" Shotaro asked as Phillip turned a key and the elevator started moving down.

"To find us an alien." Phillip said in a serious tone shocking both his partner and his friend.

The doors opened revealing a hidden hanger with the RevolGarry parked inside it.

"So we're going to Metropolis?" Shotaro asked.

"No. The alien we're going to meet is being held in a maximum security facility. He does however hold information about these invaders." Phillip said as the RevolGarry opened up and he got on board.

"So we're breaking him out then huh? Shotaro said as he got on board.

Phillip nodded and said to Akiko "We'll be back soon."

"Yeah so hold the fort for us." Shotaro said as the RevolGarry's sides closed up on them.

"I didn't hear anything about this." Akiko said as the RevolGarry drove on out of the hanger.

A few hours later the RevolGarry was racing through some woods. Shotaro was staring through the window while Phillip drove the RevolGarry via the Stag Phone.

Suddenly Phillip had a blank look on his face then just as quickly the look was gone and Phillip was quickly pressing buttons making the RevolGarry make a sharp turn and head in another direction.

"Phillip what the hell?" Shotaro asked his partner.

"Sorry, the one we seek has already been freed and is in danger not far from here. We should be there in a few seconds." Phillip said as the RevolGarry came out of the woods and parked next a strange black aircraft that was missing a wing.

Standing next to the plane was was what appeared to be the legendary Batman.

"Is that The Batman?" Shotaro asked looking at the Dark Knight.

Phillip looked at him and said "Apparently so. Means we're not the only ones here to help."

The RevolGarry opened up revealing the two detectives as they brought out their gaia memories.

"CYCLONE!"

"JOKER!"

"Henshin!" the two said as they pointed their occupied arm out to the side.

"CYCLONE-JOKER!"

Phillip then fell down unconscious as Shotaro changed into Kamen Rider Double

Double saw the battle take place in the sky and pressed some buttons on the Stag Phone making the HardBoilder detached it's green half and the rotating wheel moving till the red hovercraft half was on the bottom. The red half then attached to the black half changing the HardBoilder into the HardTurbuler.

"Watch over my body please." Phillip's voice said as Double's right eye flashed.

"Phillip, I don't think he understands Japanese." Shotaro's voice said as Double's left eye flashed.

"Oh." Phillip said as Double then got on board the HardTurbuler and flew off to join the battle.
