The second solider pulled out a grip and lifted it towards his faceplate. "Awaken."

The grip spoke: "STANDING BY..."

He slid the grip into the right side of his belt. White energy flashed around him as he transformed into the armor of Kamen Rider Delta. "COMPLETE"

Kaixa armed his Blaygun in a reverse grip and charged towards the skirmish. Delta ran at his side and opened fire with his Delta Blaster.

Bullets sparked against demons and the Samurai Rangers, blasting them backward.

Kaixa charged through the battle and slashed aside Demunio with bursts of spark. The Rider spotted Samurai Gold ahead and chopped his blade towards the Ranger's back.

But the Gold Ranger turned and blocked the blow with a burst of spark.

"Another one?" Samurai Gold kicked the Rider and slashed him upside the chest with a burst of spark.

Faiz cursed beneath his breath when he saw.

"I said focus on the demons!" he shouted to the two Riders.

Kaixa and Delta ignored Faiz.

Kamen Rider Delta swung his blaster and opened fire, blasting through Demunio. Several blasts sparked against the Samurai as they fought the same demons.

Faiz opened a commline to INET. "Cranston, your new toy soldiers are worthless. They're not following-"

"The Rangers and demons are both targets," Cranston said through the commline. "Focus on apprehending Simon."

"But you said-"

"Save your friend, Ryan," Cranston said. "Just stay out of my other Riders' way."

Eiji, Shirogane and Zadie found a massive tunnel that extended beneath the Hellfire mansion. They moved through the tunnel and made their way towards the center of the structure above.

"Do we wait to find a door?" Eiji asked. "Or do we just blast our way up?"

"You do love blasting things," Zadie said.

Suddenly, the tunnel walls sparked with electricity and surged towards the trio like waves of rock. The hunters leapt upward to avoid the wave.

Ahead, the Hellfire Club's two alchemists stood side-by-side: The White Rook Quentin and the Black Rook Kimblee.

Shirogane swung his sword wide; the blade fired a wave of energy that shot towards the two alchemists.

The rooks slapped their hands against the ground and formed a wall. The energy blade blasted through the wall with an explosion of rubble and debris that hurled the rooks backward.

Eiji and Zadie charged to attack.

The White Rook climbed to his feet. Zadie launched at him with a flying kick that smashed his chest, knocking him backward.

The Black Rook stood, placed his palms together, and started to slap towards the wall. But Eiji's staff knocked the villain's hand aside and whacked his head. The hunter spun forward and swung his staff, which bashed the villain's gut.

A group of men poured into the tunnel and opened fire with standard handguns. The hunters dove aside and took cover behind rubble.

Zadie grabbed vials of holy water and threw them down the tunnel. The vials shattered and splashed the men, who screamed and staggered as the holy water singed their flesh.

Eiji leapt from behind the rubble. "Hoi! Joso! Ketsu!"

His barrier snapped around the men.

The hunter swung his hand downward. "Metsu!"

The barrier collapsed with bursts of blue flame that incinerated the demons within the men, who collapsed to the ground.

Eiji swung his staff into a defensive stance and waited. But nothing else happened. "That's it?"

"Hey!" a voice shouted from further ahead. "Over here!"

The hunters ran ahead and spotted a girl standing on top of a pile of demon-possessed men. She wore a red-trimmed Hayate Way uniform and carried a slender sword. Golden hair flowed across her back.

It was Lauren.

"Don't worry," she said. "They're not dead."

"Yes, I was so concerned," Eiji said.

Lauren looked to her hand, still surprised by her power. Because her bloodline descended from angels, her Kiryoku could burn demons from the souls of possessed men and women. Adam Park possessed the same ability.

"Who are you?" Shirogane asked.

"My name's Lauren," she said. "Tommy sent me here to find Simon. He's...kind of my half-brother. But without the demon complications."

Tommy sent Lauren to the Hellfire mansion with specific instructions: "Whatever you do, stay with the Hurricane team. They'll keep you safe and get you in. Don't go off alone."

Lauren didn't listen well.

Zadie shook her head. "Can we speed this up?"

Eijiarced an eyebrow. "Did you hear what she just-"

"I heard," Zadie said. "Simon's half-sister. At this point, I wouldn't be surprised if half the city was related to the guy."

Shirogane gripped his sword and looked cautiously down the tunnel. "We can't stay here..."

"We don't have to," Lauren said as she pointed her sword above her head. "Look up."

They looked to see a lid that likely led to the mansion above.

Zadie looked to Eiji. "I've known her for two seconds, and I already think she's more useful than you."

"I really hate you," Eiji said.

"I get that a lot."

Lauren, Eiji, Zadie, and Shirogane entered the lower level of the Hellfire mansion.

Azmodai's men surrounded them in a hallway and opened fire. Their bullets blasted through the floor and walls and shattered vases and statues.

Zadie tossed her knife at the group ahead. The blade punctured through a man and burnt the demon from his soul as he fell.

The hunter leapt through the air, landed against the fallen man while pulling her dagger free, and swung wide, slashing through a pair of demons.

Three men swung their weapons towards the girl.

"Ketsu!"

Eiji's barrier knocked them aside before they could fire. The hunter landed on his barrier and aimed towards the attackers. "Ketsu!Metsu!"

He formed a barrier that collapsed around them with bursts of blue flame, burning the demons from their souls. The men dropped to the ground.

Eiji powered down his barrier and dropped next to Zadie. "How many times do I have to tell you. You're not-"

Behind, Lauren charged towards a wave of demons while slashing bullets from the air with bursts of spark. She slammed against the attackers as if a fighter her whole life.

The girl smashed her pommel across a demon's head, kicked the legs out from a grunt, and slashed the gun from a demon's hand.

She grabbed a man by the forehead and ignited her Kiryoku, which burnt the demon from his body with a flare of red light.

Two more men swung their guns to attack.

Lauren spun wide and slashed their guns from their hands. She grabbed them one-by-one and purged the demons from their souls.

Eiji stared silently, impressed. "Maybe I should visit this little school Tommy has..."

Azmodai stood on the center of a stone platform. The platform hovered within a cyclone, which spun within the villain's pocket dimension.

His sons surrounded him on the platform. Their bodies ebbed with shadow power that flowed into Azmodai's body as he laughed with insanity.

"That's it, my children..." he said. "Let me drink your power!"

Simon rolled his hands into fists and tried to climb to his feet. But pain seared through his every nerve and kept him pinned down. Not just his pain. The pain of his brothers. He felt Owen's fear and panic. He felt Samuel's guilt - guilt for their failure to save Brandon, and now Owen and the others.

Samuel's guilt mixed with Simon's own, and he tightened his fists so tight, his nails dug into his skin and drew blood.

Corpses. Animated corpses blocked the hallway when Lauren and the others moved to the next level of the Hellfire mansion.

Shirogane chopped his blade and fired a wave of blue energy that slashed through the zombies, blasting most of them to ash.

The hunters rushed through the remaining grunts. Zadie slashed them left and right as she charged ahead. Eiji bashed them aside with his staff. And Lauren slashed them back with her sword.

"What are these?" Lauren asked. "Are these really zombies?"'

"If you have to ask that, you really shouldn't be here," Zadie said as she hacked the head off a corpse.

Eiji stabbed his staff through a corpse's chest. "The Hellfire Club must have another necromancer..."

The floor exploded with a burst of flame, and the group crashed into a library below. Piles of corpses rained to the floor around them.

Lauren and the others climbed to their feet, as did the corpses.

Eiji cursed beneath his breath and swung his staff into a fighting stance. "This whole place is a death trap."

Ahead, two men stepped from behind a massive bookcase. One of them wore a black jacket and carried an amulet that glowed with power. A necromancer, the Black Bishop commanded the dead.

The other, the White Bishop, wore a white jacket and white gloves etched with black, demonic symbols.

The White Bishop snapped his fingers, and flames erupted throughput the library, igniting every book and shelf.

"Let me guess..." Lauren said. "A pyromancer?"

The White Bishop smiled. "Smart girl...And pretty."

Eiji lifted his staff. "Ket–"

Corpses tackled Eiji and pinned him down as smoke clouded the room.

Zadie stabbed a zombie in the chest. But the corpse collapsed onto her, tackling her to the floor.

Shirogane spun and slashed wide. But a zombie grabbed his wrist, and another corpse bashed him to the floor.

Lauren kicked a zombie upside the head. But a corpse grabbed her leg and dropped her to the floor.  

The White Bishop laughed and snapped his fingers, igniting another pulse of flame that blasted through the room.

"I can't get enough of that..." he said as he snapped again, sparking another flame. "I can't get-"

A bullet blasted the villain through the head, whipping him to the floor.

The Black Bishop took a step back. But bullets blasted through his head and chest, knocking him off his feet.

With the Black Bishop dead, the zombies collapsed into lifeless corpses.

Lauren and the others pushed themselves to their feet. They looked up to see dozens of soldiers drop down zip lines and land in the library. Dressed in all black, they used fire extinguishers to battle the blaze around them.

A suited man stepped from among the soldiers and walked towards Lauren and the others.

"Quite a mess you've made here," the man said.

Lauren knitted her brow. "Who are you...?"

"My name is Elias Kaine," he said. "Former Black King of the Hellfire Club. I've come to take back my Inner Circle."

"Simon told me about you..." Zadie said. "I thought you didn't want anything to do with this 'Ranger business'?"

"I don't," Kaine said. "But when I returned home after my last encounter with the Rangers...My mistresses tried to eat me."

Eijiarced an eyebrow. "Were they possessed or just kinky?"

"Clever," Kaine said sarcastically. "Make no mistake, I despise the Rangers, I despise you demon hunters, and I despise the demons. But if I am to live my wonderful life of sin and debauchery...it's clear I need to bring the Hellfire Club back under my control, and cleanse the rot from its core." 

Kaine pulled out his cellphone and activated it. "Commence Operation Checkmate."

A group of White Pawns and Black Pawns rushed through the upper levels of the mansion. Cellphones beeped in several of the Pawns' pockets.

Those Pawns wasted no time. They pulled out their guns and killed their companions without mercy. Loyal to Kaine, they reloaded their weapons and moved to their next target.

The Hellfire Club's White Knight and Black Knight stood guard in front of the gate that led to Azmodai's pocket dimension.

The Black Knight's phone beeped in his pocket.

The Black Knight unsheathed his sword and sliced off the White Knight's head.

Kaine led Lauren, Shirogane, Eiji and Zadie up the stairs of the Hellfire Club mansion. They heard gunfire and bursts of flame as those loyal to Kaine fought those loyal to the Black Queen and Azmodai.

Kaine stopped at one of the floors. "Keep moving ahead," he said. "You'll find Azmodai's children in a pocket dimension on the top floor."

Lauren knitted her brow. "Pocket dimension?"

Kaine looked aghast that she didn't understand.

"She's new..." Eiji said.

"What about you?" Lauren asked.

"I have a date with the Black Queen..." Kaine said as he pulled out his gun. "Go...and please don't ever let me see you or your kind again. When this is over, I want nothing but a life of wealth and luxury."

"I'm sure everything will be puppies and kittens," Zadie said. She looked to the others. "Let's go..."

Simon struggled against his chains. He felt his powers drain and seep into Azmodai, who laughed as the storm intensified around them.

The demon's skin started to peal, revealing black tissue. He smiled and looked up as his eyes turned solid black.

"This is it..." he said. "Just a little-"

His voice caught in his throat. He choked, grasped his throat, and collapsed to his knees. He still absorbed the power of his sons. But some of that power felt...tainted.

Azmodai looked to Simon and glared. "What have you done...?"

Simon felt hundreds of demons scream in his mind. The screams belonged to the demon energies he spent the past year siphoning. Many of those demons hated Azmodai and viewed him as an enemy.

Their power invigorated Simon with white-hot energy. The power felt warm, yet coated in filth.

The ranger snapped from his chains and stood.

Azmodai continued to siphon Simon's power. But that power overwhelmed the demon.

"So..." Azmodai said as he climbed to his feet. "It seems you've become powerful enough to..."

The villain staggered back with pain. "Powerful enough to resist me..."

Simon rolled his hands into fists, which ignited with black flame. He lunged and pommeled Azmodai with punches that burst with black energy.

Azmodai grabbed his son by the wrist and kicked out his legs, forcing him to his knees. The villain back-hand smacked his son's face.

"This is no way to treat your father!" Azmodai shouted.

Simon elbowed Azmodai in the gut and stood with an uppercut punch upside the demon's head. The blow whipped Azmodai to the ground.

"I'm not your son, you son of a bitch," Simon said.

Azmodai climbed to his feet. His skin pealed back and tore away, revealing a body of pure black.

"Whatever you're doing here..." Simon said. "It ends."

"You're too late, my boy..." Azmodai said as his eyes glowed with fire. "You're too late...With the blood and power of your brothers...I will finally step foot onto the mortal plane in my true, physical form."

Azmodai lunged and grabbed Simon in a chokehold. He pinned the ranger to the ground and punched his face, breaking his nose.

The demon lifted his hand and summoned waves of black wind, which circled his hand like a drill.

"Now, my son...I have need of you no longer..."

Simon narrowed his eyes and blasted Azmodai with a TK burst that hurled him backward.

Azmodai landed in the center of his star formation. He looked to his son and snarled. "It's time."

The demon slit his palm and slammed the ground, which erupted into an explosion of shadow energy.

Lauren, Eiji, Zadie and Shirogane rushed onto the top floor of the Hellfire Club mansion. They spotted the gateway that led to Azmodai's pocket dimension.

"Okay," Eiji said. "Let's-"

The gateway exploded with a burst of shadow fire. Simon and his five siblings crashed onto the floor and skid backward. Their bodies sizzled with smoke and flickers of shadow flame.

Azmodai stood within the gateway. He looked down, took a step. And his foot touched the floor.

Outside, the Hellfire mansion fired a pulse of shadow energy that smashed against the combatants and hurled them through the air. The shockwave tore through the city's Ley Lines and unraveled them.

Across the globe, lines of magical energy thrashed erratically. No longer did magical lines converge into knots, like the largest in Angel Grove. The planet's power spread everywhere, lighting the world like a supernatural beacon.   

In his physical form, Azmodai set foot on the mortal plane for the first time, which broke the Third Seal.

The demon rolled his hands into fists and summoned black Soul Metal armor. The armor looked similar to Garo's, but bulky and black, with a black cape. The villain carried a two-handed axe, and a sword attached to his waist.
