Realizing that their sister was dead, the two women tried to dash out of the red mist, but Silvy wouldn't allow it. The mist in front of the girls suddenly became thicker and two clawed hands suddenly manifested themselves and grabbed both girls by the throat. Before they could react, Silvy's head suddenly appeared out of nowhere and her mouth opened wide, wider than should be possible, and bit the head off one of the girls. As blood sprayed in the air, the other sister started in shock at her dead sister, but Silvy just gave her a wide grin. But before Silvy could finish her off, she gave screamed pain and was forced to reveal her next victim. She quickly coalesced her body as she was now vulnerable in her mist form.
Beelzebub and the others had heard their sisters and rushed forward to help, releasing multiple slashes of demonic energy towards the mist. In her mist form, Silvy, although immune to physical damage, was vulnerable to energy attacks. They were able to damage her with their attacks, forcing her to take on her physical form once more. Beelzebub rushed towards her sister and when she saw the two corpses, she gritted her teeth in rage.
"Idris, you need to get up. Now is not the time to mourn, but to get revenge." Beelzebub said and Idris slowly nodded her head as she got to her feet.
"Revenge huh, you seem so certain that you can defeat me. Why don't I put that to the test?!" She said as she flew downward towards Beelzebub. The rest of her sisters dashed towards where she was, but they weren't fast enough to make it in time. The three sisters who were busy spinning web to bind Silvy were finally finished and shot three strands of thick web towards Silvy. Sensing the danger, she stopped and used her great sword to block the webs.
"Ahhhhhhh." She screamed as she felt a great pain in her chest, looking down, she could see a sword sticking out of her chest.
"Take this you bitch." Beelzebub said and bit her into her neck. Silvy could feel the venom being injected into her body from Beelzebub's fangs and she could feel it reeking havoc inside her body. She released her greatsword, and grabbed Beelzebub with her tall hands. She forcefully removed her, ripping her own flesh in the process and threw her to the ground. The rest of her sisters arrived and used their weapons to stab the strigoi. She screamed in pain as she could feel her HP dropping at an incredible rate. Just as her attackers were backing away, she grabbed one of them and bit into her neck. She struggled to get free, but before anyone knew it, her body became limp and pale as her blood was being drained at an incredible rate.
"Much better." She said as she tossed the drained corpse to the side and pulled a spear from her stomach.
"You monster!!!" Beelzebub screamed, but Silvy just smiled. She threw the spear in her hand towards Beelzebub, who was barely able to dodge the weapon, before moving towards her next victim. She tried to fend off Silvy with her axe, but Silvy's eyes suddenly glowed ominously and her mind became blank and by the time she returned to her senses, she could feel her blood being drained out of her body. The surrounding sisters rushed over and swung their weapons at the demon, but she simply turned into mist and recoalesced a distance away. And luckily for her, she didn't die and still had blood in her body.
By this point, Beelzebub was completely enraged and golden string started flowing out of her hands and coiling around each other forming two thick, golden ropes. She swung them towards Silvy and managed to wrap one of them around her hand after a few minutes.
"Attack her with everything you got!!!" Beelzebub shouted and her sisters unleashed a barrage of slashes towards her.
"[Blood Affinity: Blood Orb]." Silvy muttered as her body was damaged by the barrage of attacks and the corpses, that still had blood in them, burst apart as the blood rushed towards her and formed an orb.
"What the-" Beelzebub said, but before she could complete her sentence, small spikes, about the size of a toothpick, were shot out of the orb, shot in all directions towards her opponents. Most of Beelzebub's sisters weren't able to dodge in time and were hit by the small spikes. Although the spikes weren't big enough to kill them, it was sharp enough to pierce their bodies, causing an excessive amount of blood to leak out and float towards the blood orb. Additionally, the wounds caused by the spikes didn't heal and they were too deep to be taken out, which made them rather painful ssince most of them had dozens inside their bodies.
Just as Beelzebub was wondering what the point of that attack was, Silvy lifted her free hand and swung down onto the hand that wad bound by the golden ropes. Surprised, Beelzebub wasn't able to react as Silvy ran towards one of her sisters and decapitated her. The sister tried to run but wasn't able to escape as the spikes in her body were too painful slowing her down greatly. Her blood floated into the air and joined the blood orb floating beside her. Finally snapping out of it, Beelzebub whipped the two golden ropes towards Silvy again, trying to bind her, but Silvy wasn't having it. She turned into red mist, but unlike last time, she didn't spread herself outward but kept the mist closely packed together.
Beelzebub's sisters tried to send more energy attacks towards her, but the spikes were too painful for them to swing their arms and Beelzebub finally realized what the purpose of the attack was. Silvy, still in her mist form, rushed towards one of the injured sisters and Beelzebub and the two other uninjured sisters sent attacks to try and stop her but Silvy didn't care. The mist enveloped the helpless woman and passed almost as quickly as it came, leaving a bisected corpse drained of its blood.
Beelzebub rushed towards the sister next in Silvy's path while sending attacks, but Silvy simply changed her target. As Silvy continued to slaughter her sisters, Beelzebub was on the brink of going mad when something miraculous happened, a red multilayered tune lit up under Silvy and she quickly took her physical form.
"Well, aren't you lucky? If I were you, I would pray that we never met again, because if we do, I'm gonna eat yah." She said, before disappearing and leaving Beelzebub and her six sisters.
