Rooftop of DEM's Building:
Tortured roars and screams echoed through the rooftop. Westcott crucified both brothers on a steel post and he used his summoned spears as a nail and a siphon to consume Dante and Vergil's powers. While he is devouring their powers, both brothers are bleeding heavily that a normal human being could've died with such blood loss.
"Once I'm done with you two, there will be no one to stop me for gaining the power of God." He chuckled, but stop and rages after Dante spitted blood on his face.
Westcott responded by piercing his whole hand inside Dante's chest and he emitted dark electrical energy making Dante roared out of agony. Westcott stops and glared at the weakened demon hunter.
"That hurts... You... You motherfucker..." Dante panted.
Westcott then faced the older son of Sparda and said. "Based on your history, is this seemed familiar to you? The feeling of helplessness?"
"I have no intentions remembering, I am only here to kill you." Vergil glared and coldly replied.
"Let me help you remember." Westcott put a hand on Vergil's head and he emitted the same dark electrical energy.
"GRRRAAAHHH!!!" Vergil roared out. His form turning back and forth between his sin devil trigger and human form.
Westcott stopped and grinned at Vergil.
"When... When I get out of here... I promise you that your death will be slow and painful." Vergil panted and growled.
Inside the ship:
The ship ascended even higher on the sky, hopefully Westcott wouldn't be able to detect them.
"Karen, I see them!" Elliot was shocked when he saw two of the brothers being held by Westcott.
"How?!" Elliot cried out in disbelief.
"It's obvious sir, both brothers are not in there hundred percent strength when they fought Westcott. Ellen and Artemisia served as a pawn to exhaust them." Karen explained.
And she added. "Westcott wouldn't even be able to handle even one son of Sparda, even though he had Nia's inversed powers and wizard magic combined with demon powers."
She looks at Elliot who is staring at her with a surprised look.
"I did some research on the brothers and both of them already surpassed all of the past rulers of the underworld, including non-rulers like their father." Karen pointed out.
Elliot glanced on his monitor again and tapped his finger against the arm rest of the chair.
"We need to distract Westcott immediately so the brothers can recover. We have enough fire power and and this ship is very durable." Elliot stated.
"Let's just wait for the right timing. Karen, contact Kotori and Shido now to hurry to the rooftop before Westcott can drain the brothers power." He added.
Karen nodded and pressed a button on her computer.
Inside DEM's Building, 2nd Floor:
Footstep echoed throughout the corridor as the smell of dead decomposing body reeks and entered the nostril of Shido and the girls.
"Not again, I think I'm going to faint." Miku said with both hands covering her mouth and nose.
Kotori's wireless earphone suddenly buzzed. She pressed the button and she heard Karen's voice.
"Hello, Kotori? Elliot will be speaking to you."
"Sir, what's wrong?" Kotori replied. She noticed Elliot's voice in a panic.
"You need to get to the rooftop quickly, Westcott had captured both Dante and Vergil, you all need to hurry before he absorbed the brothers' power! All will be lose if he - Is that thing again!"
Kotori's eyes widened and she yelled out. "Sir what's happening?!"
"Open fire!!!" Elliot roared out of the earphone.
Kotori heard the cannon of the ship being fired as a familiar roared rung out.
"Kotori can you hear me?! Get to the rooftop quickly, massive hoards of demons are approaching your way! ...GO!!! RUN!!!" Elliot demanded before his voice turned to static.
"Guys run!!!" Kotori roared out.
Shido and the girls all sprinted up to the stairways as they heard the roars and howls of multiple demons outside the building. Tohka gasped when she  peeked outside of the stairway window and she saw millions upon millions of swarms are getting summoned from the dark clouds that are descending upon the sky.
"Tohka keep running!" Shido screamed.
Rooftop of DEM's Building:
Westcott is seen flying to the sky, summoning dark clouds to summon all of his minions as he further expanded the invasion from Japan to China and Korea all the way to the the countries of South East Asia. The clouds descended from the dark heaven like smokes that has a life on its own. Once they had reached the ground, the clouds transformed into Onis and demonic samurais.
Westcott being distracted with summoning all of the demons, one figure can be seen flying to the rooftop. After the figure reached the rooftop, she quickly run up to the sons of Sparda.
"Are you going to finish us up?" Dante chuckled.
She glared at the demon hunter and replied in a whisper. "No, I'm here to help you. Whatever you do, don't make any noise."
"Why change of heart?" Vergil asked.
"Shut up before he gets here." She whispered sternly.
She grabbed the spear that is piercing Dante's right hand. When she put a hand on it, she yelped when the spear emitted a dark electrical energy. She tries again, but this time she is ready to take the pain. After a minute of searing pain, she successfully pulled out the spear and made Dante moved his right hand and arm again.
"Watch out!" Dante yelled out.
The girl that helped him immediately evaded the spear that came hurling towards her, destroying the steel post that is crucifying Dante and making him move his whole body again.
