As a Lucifer in DxD

Third Person POV

A year has passed since the start of the devil civil war. The devil population continued to dwindle and the devil pillars continued to go extinct.

Out of the 72 devil pillars only 50 remined alive after the Great Holy War, but till now in the civil war 11 devil pillars have gone extinct and the population has reached an all time low of less than a billion.

All the main leaders of the anti satan faction were in a camp outside the boundaries of Lucifaad and were planning on sieging it. 

Cain was sitting with Grayfia behind him while Zeaira, Ajuka, Serafall, Falbium, Zekram and some other devil lords sat in the camp along with him.

"As you all know all the other territories have been conquered by us only the centre stronghold of the satan faction remains. And Falbium stop sleeping."

While they were discussing some of the strategies about how to bring down Lucifaad. A devil barged in the camp and looked at Cain and said 

"Cain I also want to participate in the war meeting."

"And who the fuck are you?"

Hearing that Serafall started laughing but soon controlled her laugh. Grayfia came near his ear and said 

"My Lord it is the Oriax heir."

Cain cleared his throat and spoke again this time

"Oh you are the one who got thrashed by Shalba."

Hearing that Serafall couldn't control her laughter and started laughing loudly embarrassing the Oriax heir even more.

Seeing that Zekram spoke up to save some face for the poor guy 

"Heir Oriax please go out, we will talk about your plea at a later date."

Zekram was politely asking him to fuck off from here and he wouldn't be included in the meeting. 

Olive Oriax seeing that he was ignored looked towards Zeaira with pleading eyes thinking that she will surely help him like she did in the past.

He had fallen in love with her during the young devil gathering. He had trained himself so that he didn't need to be saved but to be the one who will save.

Zeaira being from the Gremory house said 

"Let him stay it wouldn't do any bad, right?"

Olive was happy seeing that but a cold voice cut through his happiness like a hot knife.

"No, this meeting is only for the people who have contributed enough in the civil war or have sufficient strength in the underworld not for any spoilt kid."

Hearing that Olive spoke "I am not weak I am also strong."

Seeing that Cain pressured him using his aura making him fall to his knees and cracked the ground beneath him and the spoke 

"Strong? You are pathetically weak. I only see a guy who got his ass beat in the devil gathering not someone strong. Now get out before I throw you out."

After that the poor guy understood that he couldn't do anything here. 

'Just wait till the civil war is over, I will make you regret it.'

...

Zeaira, Serafall, and Ajuka entered the city of Lucifaad alongwith Cain. Grayfia, Falbium and Zekram were left for dealing with the army.

Just as they entered the city the four of them started seizing the main facilities of the capital.

Due to their ridiculous power none of the soldiers from the satan clans were able to stand against them. In a few moments they reached Bidleid.

Even after knowing that he didn't run away like Zerekiel. At least he has guts. But unfortunately guts doesn't save you from getting killed in situations like this.

When ther squad reached the city centre they found Bidleid standing there with the elites of the Beezelebub clan ready for his last battle.

"Hey, You and Ajuka have already had their share of killing satans this is Serafall's turn right?"

Cain spoke like they were playing a game. Seeing that Ajuka said 

"Don't disrespect them like that but yes it will be Sera's turn."

"Ajuka! Don't join Cain's shenanigans you are supposed to be the intelligent one." Zeaira rebuked him while pinching Cain

Serafall had already went ahead and engaged Bidleid in the battle in which he was surprisingly adept. He was far better than any satan descendants thus far. 

The icy winds howled around Serafall as she faced Bidleid Beezelebub. The battleground was the middle of the devil capital. Bidleid, a formidable adversary with the ability to command swarms of flies, grinned with sinister anticipation.Even after knowing that he would die today.

Serafall's blue eyes locked onto Bidleid as she conjured a barrier of ice to shield herself from the incoming swarm of flies. "Your buzzing files won't save you, Bidleid. It's time to see how well you handle the might of my ice magic."

Bidleid chuckled, the buzzing of his flies forming a dissonant melody.

"Ice against the Beezelebub ? How disappointing. Let's see if your frost can withstand the storm of my swarm."

As Bidleid unleashed a horde of flies, Serafall activated her Cross Celsius Trigger. The very environment of Lucifaad was turned into a glacial battlefield. The air itself seemed to crystallize, and ice spikes emerged from the ground like frozen stalagmites.

This was only possible due to Cain ordering his soldiers to empty the capital or Serafall would not be able to use her strongest move.

"You're quite skilled with your petty tricks, Serafall, but can you freeze the relentless march of the flies?" Bidleid taunted.

Serafall smirked, weaving her magic with precision. As the flies approached, the icy terrain hindered their movements. Bidleid, momentarily caught off guard, realized the effectiveness of Serafall's strategy.

With a wave of her hand, she unleashed a barrage of icicles, piercing through the swarm and dispersing it. Bidleid, undeterred, formed a shield of flies around him.

"Impressive, but you'll have to do better than that."

Serafall's eyes gleamed with determination. "Oh, I intend to."

The battle continued, a dance of ice and swarming insects. Serafall's precision and control over the frozen terrain proved to be a potent force against Bidleid's relentless assault. Yet, the clan trait king of flies wasn't one to be underestimated.

Meanwhile, in the background, Cain, Zeaira, and Ajuka found themselves fending off a group of the elite Beezelebub clan. Amidst the skirmish, they exchanged banter.

Cain, parrying a strike with his scythe, smriked at Zeaira. "You call that destruction, Zeaira? I've seen better from a toddler."

Zeaira, her movements fluid as she dispatched foes with her PoD, retorted,

"Maybe you should focus less on annoying me and more on your aim, Cain. You nearly hit me with that last swing."

Ajuka, using his formulas to repel the goons, interjected with a monotone voice. "While you two bicker, I'm the one fighting the most."

Back in the main confrontation, Serafall conjured a blizzard, swirling winds of ice that engulfed Bidleid. The King of Flies struggled against the freezing tempest, his swarm disoriented and dispersed.

"You're persistent, Serafall, but you can't freeze my flies!" Bidleid's voice cut through the blizzard.

With a burst of demonic energy, Bidleid emerged from the blizzard, his form wreathed in a dark aura. The flies, revitalized, swarmed around him once more.Serafall, her breath visible in the icy air, smirked.

"I'm not done yet."

With a snap of her fingers, the icy terrain beneath Bidleid transformed into a field of razor-sharp ice shards. Bidleid, caught by surprise, found himself on unstable ground.

"You underestimated the power of my Cross Celsius Trigger. Now, let's see if you can stay alive for long." Serafall declared.

As Bidleid struggled to navigate the icy terrain, Serafall seized the opportunity. She unleashed a barrage of icicles that converged on Bidleid, piercing through his defenses.

Bidleid roared in pain, the ice was spreading through him he cut of his arm to save himself.

In the background, Cain, Zeaira, and Ajuka had almost dealt with the goons.

Cain, delivering a swift strike, quipped,

"You know, fighting goons is therapeutic. Like a devilish stress ball."

Zeaira, gracefully dodging an attack, added,

"Therapeutic? I think you just enjoy the sound of your own scythe clashing."

Ajuka, manipulating demonic energies, said.

"Well, at least it's a good distraction while Serafall works her icy magic."

Back to the battle between Serafall and Bidleid 

Serafall, a smirk playing on her face said "Looks like this ice girl is stronger than the Beezelebub."

 "This isn't over." Bidleid tried to but his arm was cut off, half of his wings frozen and broken while one of his legs was completely frozen.

Seeing that Serafall tried to offer him a surrender but was met with a ferocious response 

 "I won't surrender, The blood and wrath of the Satans shall always stand against you"

Hearing that Serafall creted a spike of ice and pierced his heart and brain officially bringing an end to the cruel and gruesome devil civil war.

Bidleid PoV

'I hope I buyed you enough time my son, Shalba. I put my faith in you that one day you will dethrone these fake devils and revive the pure Beezelebub clan.'

...

Serafall PoV

I was born at a very young age. I had a mutated clan trait which allowed me to use ice magic. I was a prodigy in it. I grew very strong but I liked more to be helpful to the devils of my territory.

The sitri's are know for their medical abilities, so most of the hospitals in the underworld are owned by my family.

I was always ready to help fellow devils. My friend also had a similar mindset. Even the Lucifer aka Cain-kun was not as bad as the other satans. 

So when Zekram asked me to support the rebel faction, I joined. I knew the cruelty the satans do in their territory, the patients were traumatized for life.

At first no one joined, but after a major incident every one Zeaira-Chan, Ajuka-kun and Falby joined too. And to top it off Cain-kun joined it too.

The strongest person I ever fought was Cain-kun but Gerhard Lucifuge with his skills was also very strong and to think he died like that. I wanted to help Grayfia-Chan but I left that to Cain-kun.

Now that finally the civil war has ended I can go back to my normal life, I will make sure that the underworld is a better place for all the devils.

After that everyone was in a good mood for celebration. The squad met up with the ones fighting the satan army. After learning of the defeat of the Beezelebub the satan faction lost their drive and surrendered. 

Seeing that Zekram came and started to speak to the lords and the heroes of the civil war.

"This war was won due to the great efforts of the all the devils. But even in them some have done greater things. These are Zeaira Gremory, Ajuka Astaroth, Serafall Sitri and Falbium Glaysa-Lobolas."

Many were confused not hearing the main devil Cain's name but Zekram continued. 

"So I want to nominate these guys as the next satans after the complete surrender of the satan faction and getting things in order there will be a ceremony.-"

He was continuing but Cain interrupted him and said 

"You were giving a nice speech old coot but the main villian hasn't even been defeated yet."

"What are you talking about?"

"You shouldn't forget that aside from the satan descendants which ran away and went out of the underworld and me, there is another satan child and he hasn't told us his alignment has he?"

Hearing that everyone remembered about Rizevim. Cain's reminder made everyone think again as if Rizevim supported the satans faction due to him being a Lucifer the civil war may be restarted.

"Ah, dont worry about it. I am here to stop him aren't I."

"Are you sure you can?"

This time it was the Lord Gremory who asked. Not many knew about the fight between the malebranche and Cain so they still thought that he was only a good commander and not fighter.

"The next fight which will start shortly will probably answer your question Lord Gremory."

Everyone wanted to ask him what that means when a voice boomed in the silent battlefield

"Been a while brother."

AN:- We are getting closer to the end of the civil war arc alongwith the volume. The fight between the brothers.
