In The Abyss:
Helpless agonizing cry echoing inside this hellish void. Shido thrashed and wriggles, hoping the hands that are subduing him lose its grip. Unfortunately, the demonic hands holding and scratching his limbs only got tighter while they pass him over to another. From Shido's suffering, the succubuses giggled and moaned out in pleasure as they feed themselves with the boy's torment.
Blood already dripping out of Shido's mouth. His screams became hoarse until he can hardly emit any sounds. His vision is starting to get blurry and the blood pouring down his face only worsen his sight. 
He wanted to faint, he wanted this suffering to end, he wanted to die. However, it feels like these demons surrounding him are preventing him to have some peace.
"Don't worry sweet little Shido, we are almost there and your pain will be over." One of the succubuses giggled as she licks the blood on Shido's face.
As they move forward through the abyss, a gust of wind brushed against Shido's face. The shadow around him transition into giant trees and thick bushes. The hands that are immobilizing him disappeared and he fell on the grassy ground.
He looks around his surroundings, no demonic hands and no other demons -- nothing. Not wasting anymore time, he quickly stood up, however he fell back down cause of the sharp pain he is feeling throughout his whole body. The purple flames that are healing his injuries are too slow, he will surely lose tons of blood and die before the flames closed up his wounds. He exhaled a sharp sigh out of frustration before closing his eyes and pray, hoping the others will find him very soon.
"Wake up!"
He groaned out in agony when he felt a gut wrenching blow hits his stomach. He coughed and vomited violently while the succubus laughed at him.
"N-No more!" Shido sobbed.
"I've never seen little Shido so helpless before?" The Succubus chuckled. 
The demoness grasp Shido's hair tightly before spreading her wings and started flying through the forest. Shido being used like a ragdoll, his body scrapes over sharp fallen branches and hard rocks.
From the pain, Shido's consciousness instantly fade after feeling the final straw. His mind already at its limit and already endured enough suffering. His body got pierced by small and large splinters while his bones crunched and crackled after hitting huge rocks and boulders.
Tengu Forest:
"How long will you keep fighting douchebag? You know you can't win this fight."
Dante aggressively picked up Westcott from the ground. Using his demonic powers, he summoned red rings around Westcott to chain him in place.
Dante looks over at Vergil and spoke. "What're your plans with him?"
"My actual plans are killing him, however let's not risk one of the two demon Kings inside him to take control over his body. We will separate both demon and human using the Yamato."
"Mundus and Pluto will be set free after this. That means?"
"More fun." Vergil unsheathed his sword. Yamato got covered by a dark blue demonic energy.
When Vergil was as about to pierced Westcott with the sword, the elder son of Sparda got tackled on the ground by a succubus with Dante getting the same treatment like his brother.
Both brothers easily eliminated their attackers, unfortunately Westcott's binds disappeared in a flash. He threw two spears towards the brothers and it pierced them on the stomach, sending them flying to multiple trees.
"Ugh... Damn that hurts!"
"Argh!"
Both brothers tried to stood up, however the spear piercing them sends an electric shock all over their bodies making them fall into their knees. The spears transformed into a cage with just a right size for both of them. The cage then sends electrical current throughout their body to keep them paralyzed to prevent them escaping.
"Smartass!" Dante yelled out.
With the last demon standing, Westcott glared at his succubus one by one, making them flinch and cower.
"Where's the boy?!" Westcott roared out.
"They already on their way father!" The succubus whimpered.
"Then what's taking so long?!"
Suddenly, Westcott glanced to his right when the trees got destroyed and the leader of the succubus appeared out of nowhere holding a bloody Shido on her hand. The succubus throw the boy in front of Westcott, making him lick his lips and chuckled.
"Finally..."
When Westcott was about to take Shido, he got hit by a blast of steel melting beam over the sky while the succubus around them got shot by golden blast of lasers.
"Damn you!!!" 
Tohka was about to sliced up Westcott with her broadsword, but one of the succubus blocked it using her long sharp blade like nails.
Westcott glanced at the higher succubus and ordered. "Distract the spirits while I take the boy!"
"Yes father!"
Without wasting anymore time, Westcott put Shido's unconscious body over his shoulder and flew off. Unknowingly, the battleship of Elliot blocked his way.
"Return the boy to me Westcott, so we can settle this once and for all!" Elliot voice demanded through the speakers.
"Get away from my brother!!!"
Westcott barely dodged the incoming flaming halberd that was about to slash. He smiled at the flame spirit who is breathing heavily while looking at him on the eyes with killing intent.
"Itsuka Kotori, it is nice to see you again." Westcott greeted her with a mocking tone.
"Give him back right now!"
"What if I refused, what will you do then? Kill me?" Westcott laughed.
"You are only a petty spirit, your powers won't work on me."
Westcott summoned a spear on his hand. When he was about to throw it towards Kotori, he got shackled by a chain with a spear end. Shido fell from his shoulder. Thankfully, the other Yamai, Kaguya, caught Shido. 
"Hurry! Me and Kotori will hold him off!" Yuzuru yelled.
Kaguya flew far away from Westcott, hoping her sister, Yuzuru, can make time for her to hide Shido away from these demons. Unfortunately, he got tackled by one of the lesser succubus and Shido starts plummeting to his doom.
"Shido!" Kaguya cries out.
Shido got caught by two succubuses. When they about to summon a portal, both Tohka and Origami strike down the she-demons. They tried to fly away, but they got surrounded by succubuses.
"You think we will give up the boy so easily?! Father will prevail!" One of the succubuses roared.
Two familiar screams were heard when Westcott break free from his chain. He subdued Kotori and Yuzuru by placing them inside an ethereal cage made of spears. He opened his mouth and his jaw bone splitted like a snake. The girls let out a painful scream as their powers started to get suck out of them.
After absorbing every last drop, both girls lay inside their cage pale, naked, and unconscious. The cell disappeared with the girls after a dark purple aura consumed them.
"Now, let's see what I can do now." 
Westcott enchant his summoned spear with the fire of the flame spirit before hurling it towards Tohka and Origami.
Unfortunately for him, Natsumi and Miku used their angel to block the spear by using a sound barrier, but the spear exploded into a mass fire, burning the shield of both spirits and sending the girls with Shido crashing down to the forest floor.
Westcott laughed as he landed on his feet. He started approaching Shido slowly. Suddenly, multiple clones of Kurumi with the original appeared before him, blocking his way to his victory.
"I won't let you have him!" Kurumi glared at the fallen founder of DEM with guns lock and loaded.
Westcott chuckled. "What do you say we make a deal? You hand me over Shido and I will take you to the first spirit so your revenge can be fulfilled?"
Westcott slowly steps forward, but a warning shot stops him.
"Oh come on nightmare, stop pretending you cared for Shido. You only want his power so you can kill the first spirit, am I wrong?"
Kurumi gritted her teeth and yelled. "You're wrong! Shido protected me, almost died for me! I'll be glad to do the same for him!"
"Fine by me." Westcott growled.
With that statement the original and her clones opened fire. Westcott summoned his spears and spin it with unmeasurable speed to block out all of the bullets.
"Useless!" Westcott roared.
"Zaphkiel! Zayin!"
Westcott eyes widened as Kurumi shot out a special bullets from the muzzle of her pistol and rifle. Westcott quickly fly through the air trying to dodge the projectiles, but immediately got hit and freeze in time.
Kurumi summoned a large spiky tentacle shadow from the ground. It wraps itself around Westcott like a snake captured its prey and started to pulling him to the shadow.
"Begone monster." Kurumi stated with venom in her tone.
"Too bad!"
Kurumi's jaw dropped after Westcott breaks out from her time freeze. He quickly used his powers to absorbed the shadow that are binding him and he quickly flew towards the original Kurumi after being completely released.
"Urgh!"
Westcott wraps his right clawed hand around Kurumi's neck before lifting her up. All of the clones glanced behind them with fear and surprise.
One clone wearing a gothic dress and an eye patch immediately charged at Westcott while blasting her pistol rapidly at him. Westcott block his body using his wings, repelling all the incoming bullets. When the clone Kurumi is almost close to him, he threw the original Kurumi at the clone's direction bringing them both into a collision.
Westcott's hands glow a dark purple aura. Without any warning, all the other clones got impaled by multiple spears that Westcott summoned from the ground.
Westcott smiled, satisfied knowing there won't be anyone else to stand on his way. However, he quickly took a step back when two figure nearly cut him in down.
"Glad to see you again traitor!" Westcott growled.
The girl wielding the power of the Gashadokuro, Artemisia and the spirit nicknamed Zodiac, Mukuro are now standing between him and Shido.
"You think the two of you can stop me?" Westcott taunted.
Another spirit appeared behind the two. It was the second spirit, Nia and she already summoned her minions similar to the nibelcole, named, Maria. Over the sky, the battle ship guns wailed and roared, eliminating all of the succubuses that are infesting the area.
"You're surrounded Westcott! Surrender or die?!" Elliot demanded.
A bright yellow flash occured and Karen appeared standing there all suit up for battle and blades ready on hand.
Westcott chuckled until it turned into a full laughter like a maniac.
"You stupid fools! Without the sons of Sparda guiding you, all of you are just a mere annoyance to me." Westcott glanced at all of them, but his eyes ended up on Shido.
"I need to consume that boy quickly before Dante and Vergil destroy their shackles."
"I'll go easy on you. Are you all ready?" Westcott suddenly disappeared from where he is standing, shocking all of the people around the area.
Suddenly, one of the Marias get in front of Nia and she cries out in pain as her heart gets pierced by Westcott's burning spear. The others are in shock on how quick Westcott got so close to them.
"Everyone get away quickly she's gonna explode!!!" Artemisia demanded.
She quickly run up to Shido and imprisoned herself and him inside a metallic cocoon like case while the others run away from the death zone. The Maria that Westcott caught glowed a fiery red. Her skin started to melt while eyeballs exploded.
Westcott charged her with flame energy as she started to bloat until...
*BOOM!!!*
Inside the cocoon, Artemisia mumbled. "He is very different than before, I can sense... Kotori's power and not only that others as well. This is very bad."
