Prologue
Gremory Territory 13 years later…
Deep within the forest of the Gremory Clan stood two devils facing each other and they were none other than Gallus Valefor and Sirzechs Gremory.
"Can we get this over with I had to pull a lot of favors to get this time off" said Gallus with a serious face.
"Come on this is the first time I have seen you in 2 years so I want to enjoy this" replied the red haired devil with a grin.
With a nod Gallus summoned a ball of hellfire wanting to get this over with fast he threw it at Sirzechs who threw his own orb of destruction causing an explosion, using the dust to his advantage Gallus flew through it and channeling black fire in his fist he punched Sirzechs with tremendous force knocking him into a tree.
Walking over to his friend Gallus offered to help him up which the red head accepted.
"You just go promoted to Ultimate Class a week ago why did you want to fight me you knew how this was going to end" said Gallus as the two started walking back to the Gremory mansion.
"Yeah I know it's just fun fighting you"
"Even though you constantly lose" said Gallus with a raised eyebrow.
"Yeah if I keep fighting you I know I will get stronger" Sirzechs replied.
"You really are an odd ball" Gallus remarked with an unamused tone with a completely serious face
"Well at least I can smile unlike you" Sirzechs joked back.
Gallus could only groan in agreement as it was mostly true, after Lucifer made him his student Gallus became even more serious and stopped smiling or joking altogether in the public eye for very few knew that Serafall Sitri was the only one who could get Gallus to smile.
"Anyway why did you ask me to come to your family's territory what's so important you can't tell me via magic?"
"You'll find out once the others get here now let's hurry"
Hours Later Gremory Family Library...
Sitting at a circular table sat Gallus Valefor, Serafall Sitri, Ajuka Astaroth, Sirzechs Germory, and finally Falbium Glasya-Labolas, they were all silent as Sirzeches ordered all the servants to leave them alone.
"Alright now that we are alone why did you ask us to take leaves from the war?" asked Falbium getting nods form the others.
"The reason that I called you all here is that I have received word that the entire Buer Clan as well as the Gusion Clan were completely destroyed and not a single devil survived" Sirzechs stated getting looks of shock from all but Gallus.
"Impossible are you sure?"
"This is bad"
"That makes 38 clans that have been wiped out along with the overlords"
"ENOUGH" Gallus shouted getting all of their attention.
"Look our race isn't the only one that has suffered the Angles lost Raphael, Uriel and finally God-"Gallus said but stopped due to the headache they all got from mentioning God before continuing.
"And the Fallen have lost Chazaqiel and Ramiel so I am fairly certain that all three factions would be open to ending this war" Gallus stated.
"And what makes you certain that they all would?"
"No one wants their race to go extinct and with all the death this war has brought I can only assume that every faction needs time to gather their numbers and strength. But what really tells me this is the fact that my father has confirmed that the Fallen Angles have all but retreated"
"How can your father be certain?" Ajuka asked receiving an angry glare from Gallus who replied with.
"My father Corbec Valefor is the Grand Marshal of the Devil military just under lord Asmodeus when it comes to matters like this he is always right so do not doubt him" Gallus all but shouted while releasing some of his demonic power.
Normally Gallus would let a comment like that slide but when anyone said something negative about his father, mother, or brother Gallus would drop his usually calm demeanor and let his anger out.
Wanting to diffuse the situation Serafall started stroking Gallus's hand to sooth him before turning to Ajuka with a glare of her own.
"Apologize" she ordered.
After a quick apology Ajuka sat back down and Falbium decided to ask one last thing.
"What about the Overlords descendents?"
That one question caused complete silence as everyone knew that Shalba, Creuserey, and Katerea would not want peace at all but the one they were most worried about would be Rizevim and Lucian as they were wild cards.
"Let me see if I can convince either Lucian or Katerea since the former is my best friend and the latter is my fiancé" Gallus spoke up but as he finished none saw the look in Serafall's eyes when he said fiancé.
"Alright Gallus you'll focus on convincing those two to gather all the reaming clans into throwing a meeting and I will focuses on the other descendents" Sirzechs stated bringing the meeting to a close.
Later….
After finishing the meeting Gallus decided to use the time he had off to visit Valefor territory and not surprisingly Serafall decided to come along with him due to the two of them being secret lovers forcing them to find any excuse to be alone.
"You made quiet the show by losing your temper and here I thought Gallus Valefor never loses his temper" Serafall teased.
"Well how would you react if he indirectly insulted your father" Gallus replied giving Serafall one of the secret smiles that he only showed her.
"I guess you got me their but enough about them were you serious about talking to Lucian and Katerea?" Serafall asked gloomily when she mentioned the women Gallus was set to marry.
Noticing her discomfort Gallus took Serafall's hand and looked her in the eyes.
"You know that I have been trying to terminate this marriage contract ever since I was told about it"
"I know and I've been trying the break my engagement to Ruval Phenex but thanks to the war all that I've been able to do is delay it"
"I know and trust me we will get out of this and when this war is over I will make it clear that I love you "Gallus said with passion a rare thing from him.
Touched by the sincerity and love in those words Serafall leaned forward and kissed Gallus and the two stayed in each other's embrace until they reached Valefor territory.
Upon reaching the Valefor castle Gallus and Serafall were greeted by a multitude of servants eager to see the heir to the family return but what surprised Gallus was that Coran was also there to greet him as he thought his younger brother was currently still attending the Lilith Devil Military Academy.
"Brother what are you doing here and why did you bring Lady Serafall?" Coran asked as he was the only one besides Serafall's friends who knew of their relationship.
"I came to see how mother was doing"
That caused Coran as well as some of the servants to look uncomfortable as their mother Mira Valefor had been born in Marbas Clan one of the clans that was now extinct leaving her the last of her line.
"It's not good with you and father off fighting and me at Lilith she's been really depressed and worried for your safety and according to Wilhelm she has stayed locked in her and fathers room"
Wilhelm van Astrea was a pureblood devil from the Extra Demon clan Astrea who had always served the Valerfor Clan as their butlers and servants and in addition he was the childhood caretaker and swordmater of Gallus
"I can try to comfort her while the two of you talk" Serafall offered surprising the brothers.
"Yes that seems like a good idea what do you think Coran?"
"I'm ok with it mother already thinks of you like a daughter and I already see you as a sister"
Hearing that made Serafall blush and want to scream in happiness as she wanted to call Mira her mother-in-law and Coran her little brother.
With that Serafall a maid took her to the Lord's and Lady's bedroom and knocked on the door.
"Lady Valefor you have a visitor"
"Who is it?" an almost emotionless voice asked.
"Lady Serafall Sitri my lady"
"Send her in"
Mira Valefor had always been a cheerful and optimistic person the polar opposite of her silent and stoic husband but the person in front of Serafall was not that person. Her one pristine and beautiful light brown hair appeared to have dulled as if she had stopped caring for it and her red eyes which Gallus inherited had bags under them and it appeared she had lost weight as well.
"Serafall what can I do for you?" Mira asked lying in bed.
"We need to talk" Serafall answered taking a seat in a chair by the bed.
"What do we need to talk about?"
"Everything but most especially about Gallus"
"Why do we need to discuss Gallus?"
Meanwhile…
While Serafall was comforting their mother the brothers decided to catch up as they had not seen each other in 2 years due to Gallus campaigning alongside Lucian and Rizevim against Michal and his angels.
"You'll be graduating from Lilith this year right?" Gallus asked in his usual serious tone after taking a sip of Earl Grey tea.
"Yes but mother is dead set against me joining you and father"
"It is understandable I mean our family has lost most of our extended relatives"
"I know but I want to at least taste some combat big brother and it seems like the war will be over once my class graduates what with Azazel pulling his forces out" Coran responded surprising Gallus as he didn't know that was public knowledge yet.
"How did you find out about that I only got word 2 days ago?"
"You don't need to worry about that big brother" Coran said grinning.
"Humph well there is one thing I need to ask you and I need you to listen" Gallus said leaning forward.
"And what might that be?" Coran responded.
"Me and some of the other heirs are going to ask lord Bael to call a meeting between all the remaining clans and we are going to propose that we cease fighting and focus on the restoration of our territory and breeding to fill our numbers and I need to know little brother will you stand beside us" Gallus finished offering his hand.
Coran had his mouth open in shock as he was beyond surprised that his older brother would be one of the devils on the side that supported peace. Coran hesitated before he spoke.
"What about father you know he would want to keep fighting?"
"That's why I need you to side with us hopefully the two of us can convince father that it would be in the Valefor's best interest to support peace"
"I must be crazy" Coran said shaking his brother's hand and then replying
"But what do I have to lose"
"Absolutely nothing"
"Now if there is nothing else can I ask you a question?"
"That depends on what it is"
"Why did you really bring Serafall here?"
Gallus took a deep breath before looking at Coran as red eyes met yellow.
"In the coming weeks I am going to speak to Lord and Lady Sitri about marrying Serafall" Gallus responded with a blank and serious face while Coran had to blink and shake his head if he heard him right.
"Are you serious you're not joking?"
"When have I ever joked" Gallus pointed out.
Coran who couldn't recall a time started to burst out laughing and Gallus could swear that he even saw a few tears threaten to come out his eyes.
"Your right in all the years you have never even cracked a joke you must really love her but I must say you have weird taste in women"
"What do you mean?" Gallus asked raising a dark brown eyebrow.
"The obsession she has about getting a younger sibling"
"Well" Gallus said before Coran interrupted him.
"Not to mention how every time she sees me she treats me like a teddy bear" Coran stated reminding Gallus that even after they had grown Serafall would pick up his little brother and swing him around like a toy.
"Alright enough I know she's an oddball but she makes me happy a lot more than that bitch Katerea would make me"
"You misunderstand big brother I like her she's been like a big sister to me" Coran said not noticing Serafall was right behind him with tears in her eyes.
"Well it's about to get worse for you" Gallus said in his unusual tone pointing towards Serafall and once Coran saw her standing their he knew what was going to happen. Before Coran could do anything Serafall rushed to him and started kissing Coran on the cheak and saying.
"Thank you little Cor from now on you can call me big sister" Serafall stated happily before going over to embrace Gallus.
"Does this mean" Gallus started before Sera interrupted him with a kiss.
"Yes it does lover" Serafall said using the nickname she used when the two were alone.
Making his presence know Coran decided to speak his mind "If you two are going to do something please take it into a bedroom" he stated not knowing that as soon as he would leave the room the two of them would.
Later that night in Gallus Valefors room…
Lying in bed was Gallus and Serafall both naked as the day they were born and in postictal bliss. Serafall had a big smile on her face as she was cuddled against Gallus as he ran his hand all along her back.
"I still can't believe your mother agreed" said Serafall causing Gallus to stop caressing her.
"She was always against the match between my clan and the Leviathan clan so I'm not all that surprised" that she agreed but the real thing is what will your parents and the Phenex clan say?" Gallus responded and was rewarded with Serafall pinching his cheek.
"You let me worry about my parent's I'm sure they will relent once they find out that we really love each other and because well you know" Serafall stated but then trailed off.
"Well it can't be helped now so let's get some sleep"
"Alright" and not long after saying that Gallus heard the quiet sound of Sera lightly breathing as she slept a sound he always enjoyed smiling Gallus closed his eyes ready to deal with the shitstorm that was about to happen and fell asleep…
Few weeks later Military Compound outside Lucifaad
After contacting Zekram Bael Gallus and Sirzeches were able to convince him that they needed to gather all the heads of the remaining clans to discuss the state of the underworld and the ascension of new Satans.
All remaining 34 clans were in attendance either coming personally or through a thought projection if they couldn't make it due to the war but they didn't want to make the great king Zekram mad.
Standing in the center of the room stood Gallus dressed in clothes that befitted a noble in the colors of the Valefor Clan maroon and black as he was conversing with his friend and fellow Lilith Academy graduate Kieran Valac heir to the Valac family but stopped when he felt eyes on him.
Turing his face Gallus saw that the descendents of the original Satan's were watching him very closely, excusing himself Gallus walked over to the four of them.
"Good to see you again Lucian" Gallus greeted after shaking his friends hand.
"Stressful ever since my grandfather was killed and father decided to go into isolation" Lucian replied with heavy bags under his eyes indicating that he hadn't been sleeping a lot lately ,"Now why has Lord Zekram called this meeting when there is a war going on?"
Knowing they would be against ending the fighting Gallus chose to act ignorant of the true meaning of the meeting.
"No my lord all I was told was that all remaining pillar heirs and military commanders were to come here so your guess is as good as mine" Gallus replied in his usual emotionless and cold tone.
"Yes and while we stand here and talk there is a chance that the angels could attack" Creuserey the descendent of Asmodeus stated, it was a pity that lord Asmodeus sired such a disappointment of a son a man who believed that he was automatically better than everyone and refused to believe the truth that Gallus and his friends were stronger than him.
Signing in annoyance Gallus turned to his "beloved fiancé" Katerea Leviathan who for some reason had hearts in her eyes and was that drool Gallus saw as she was looking at him.
"As long as it's quiet for a time that means that I can finally marry Gallus like we are supposed to" Katerea stated with a smile forcing Gallus to put on a fake smile as he noticed Serafall and Creuserey both send him glares.
"We still need to rebuild and stabilize our economy before we do that" Gallus pointed out wanting to get the crazy Leviathan heiress off his arm.
"True but that can wait until we wipe out our enemies" said Shabala making his presence known before turning to Lucian "What say you Lucifer?"
Lucian gasped as he wasn't expecting to be called Lucifer.
"You are mistaken Shabala my father is the one who is next in line to be leader" Lucian said before noticing that Zekaram was calling for every devils attention.
"May I have your attention" Zekram stated as all the devils were settling in their seats to listen.
"You all may be wondering why I called every Pillar Clan head and heir to this meeting as you all know that the Fallen Angles have completely pulled out of Devil territory and there are only a few very small forces of Michal's angels left now the question is what do we do" Zerkram said then taking a seat letting the younger devils debate.
"What do we do it's obvious we destroy them!" one voice shouted and was joined with others.
"No we should gather our strength and propose peace" another voice said.
"Shouldn't lord Rizevim have the final say where is he anyway" another voice stated as the devils went back and forth debating.
Gallus stood in silence contemplating on when he should intervene but before he could say or do anything. After an internal debate he decided to ask for the floor.
"Lord Gallus what do you suggest we do?" a random devil asked.
"In my opinion it was the teachings of Lucifer and the other Satans that led to this..." Gallus started and was met with some disapproving looks but continued. "Due to those teachings we have lost 33 Clans and countless friends and the Underworld is in a state of decay"
"So what?" an angry Creuserey Asmodeus stated looking at the Valefor heir with contempt while Gallus just faced him with a neutral expression before continuing.
"If we don't stop fighting it may lead to the complete destruction of our race as a whole, so I propose that we focus on rebuilding the Underworld and replenish our numbers before we even think about fighting anyone" as soon as he finished speaking someone in the audience fired a shot of magical energy directly at Gallus which he effortlessly blocked with one hand.
Turning their heads everyone was shocked to see that it was Shabala who fired the shot.
"You traitor how dare you propose peace" he roared and was soon joined by the other descendents of their leaders save Lucian.
"Look Shabala your grandfather as well as the other Satans would have led us to destruction if they were still alive and the same could be said for any of you" Gallus said trying to keep his temper in check.
"What are you saying Gallus?"Katerea said shocked that her 'beloved' fiancé would say that about her.
"I'm saying that in order to survive we need new leaders that won't continue the war" Gallus stated.
"So instead of fighting you suggest that we rebuild and focus on breeding for a few generations and implant a new form of government in terms of leadership" Zekaram summarized.
"That is correct".
There were a few moments of silence until Zekaram stood up and said "The Bael Clan supports this motion all others in favor raise your hands".
Gallus and his friends were the first to raise their hands and were soon followed by Coran and a few devils his age and then they were followed by 19 Clan Heads showing that they had the majority vote.
The descendents of the original Satan's were furious no that would be an understatement they were absolutely livid, not only had the devils decided to not avenge their fallen leaders, they had stripped them of their birthright but if they thought they were going to take this laying down they were dead wrong.
Lucian couldn't believe that his best friend would do this to him; in all the years he had known Gallus not once had he ever talked about being dissatisfied with the Devils choices he thought once he became the Devil's leader Gallus would serve as his right-hand man but apparently not, in a fit of rage Lucian walked up to his now former friend.
"Lucian listen I" was as far as he got before the silver haired devil grabbed him by the collar of his shirt.
"How can you do this to me?!" Lucian screamed.
Gallus took a moment to wipe spit off his face before replying.
"I know you're mad but we need to think about the future not inflating our egos by continuing the war this is what's best" Gallus reasoned.
"Well I won't stand for this" Lucian said shoving his now former friend away while turning to the assembled devils.
"You are all traitors to Lucifer by choosing peace and as a 'true' Devil you should want to extermante the angels and fallen " Lucian said as he was joined by the other Satan descendents and the remaining 16 Pillar heads and surprisingly Corbec Valefor.
"If you are not with us your against us" Lucian finsished and flared his power.
"You really won't back down will you?" Gallus asked Lucian before turning to meet his father's gaze.
"Not until we are deemed the true leaders" Shabala said.
"Then I guess this means war" Serafall said as she and all the Devils supported peace got behind Gallus creating a literal divide.
"Yes it does" Lucian said activating a Magic Circle leaving and was instantly followed by all on his side save Corbec Valfor and his guards.
Gallus and Coran held their fathers gaze none of them dared look away until Coran started to speak.
"Father I…" but was cut off by his father who said.
"How did both of my sons turn into cowards who are too afraid to fight" their father stated with disgust clear in his voice. While Coran was hurt and looked down Gallus held his gaze.
"You both disgust me" Corbec said before actuating his own Magic Circle and left.
After all the Old Satan forces left Zekaram assumed leadership of the now named Anti-Satan Faction and ordered everyone to gather as many troops as possible over the next 2 weeks and gather in Bael territory to decide on a course of action.
4 Hours later outside Sitri mansion…
After a secretly entering Valefor territory and gathering what few Valefor Family guards that were loyal to him he decided now was the time to confront the Sitri and Phenex families as her engagement party was set for tomorrow.
"Are you sure now is the time?" Sera asked while holding hands with Gallus.
"We won't get a better chance best get it over with now" Gallus said before kissing her.
After being announced the two were led to a room where in sat 5 people, Lord and Lady Sitri and the Phenex Lord and Lady and finally Ruval Phenex.
Upon seeing his daughter Lord Sitri rushed to hug and greet her.
"Sera what are you doing here your party isn't until tomorrow" Lady Sitri asked after she hugged her daughter.
"There is something we need to talk about" Serafall said sitting down and motioning Gallus to take a seat beside her.
"And what might that be "her father asked.
Taking the hand of her beloved she took a deep breath before saying "I don't want to marry Ruval, I want to marry Gallus"
This caused Lord Phenex to spit out his tea and Ruval to now look at her with a hurt expression.
"Absolutely not do you know what this would do to our family's reputation as well as the Phenex's "Lord Sitri said with Lord Phenex agreeing with him before Ruval decided to speak.
"Sera with this new civil war we need this wedding to happen so neither the Sitri or Phenex break ties with each other I'm sure you understand" Ruval stated before turning to Gallus.
"Not to mention you marrying the heir of an Old-Satan family would cast doubt on your allegiance"
In a flash Gallus grabbed the blonde Devil by the neck and forced him to look him in the eye as red meet blue.
"If it weren't for me we would still be deciding on what to do and if you hadn't noticed me and my brother joined Lord Bael instead of our father so I will hear no word about doubt to mine or Sera's allegiance" Gallus stated in a cold and dangerous tone.
"It's clear you my daughter love each other very much but there is nothing to be done I'm afraid" Lady Sitri said.
"Actually there is "Lord Phenex said shocking everyone.
"And what might that be Rarran" Lord Sitri said puzzled the Phenex head would allow the Valefor to challenge his own son.
"If you can defeat my son in combat then Lady Serafall's hand is yours if not then she will marry my son it is as easy as that"
"But why would you even allow me to fight your son" Gallus said wanting to know the Clan leaders reasoning.
"If you win it will motivate my son to achieve power greater than your own and maybe my son can find a women he loves on his own instead of being a good boy and following my every wish" Rarran stated.
"Thank you father" Ruval said before turning to the brown haired devil, "I accept your challenge" he stated.
Standing in the courtyard of the Sitri mansion stood two devils facing each other, Gallus Valefor and Ruval Phenex both stood there watching and waiting for the other to make the first move.
Ruval broke the silence when he fired a stream of fire out his hand, Gallus swiped the fire away with single swipe of his and used the momentum to launch a ball of hell fire. Ruval dodged the flames but was surprised when the ball of flames increased in size the moment that it was behind him and he was caught in the explosion.
Taking advantage of the situation Gallus used his wings and flew 20 feet into the air, Ruval thanks to his regeneration was back up but still showed signs of being hurt. Spotting Gallus Ruval decided to use his trump card, Using his fire magic Ruval surrounded himself in fire turning himself into a literal Phoenix he launched himself right at Gallus.
Watching Ruval get closer Gallus decided to try something new, bringing one hand back he decided to use his family power but he added wind magic, Once Ruval was close enough Gallus threw the black spiral of wind at the phoenix, once it made contact it turned into a large black whirlwind that stripped Ruval of his flames and violently thrashed him around for a good 3 minutes before fading away.
'It's over' Gallus thought before landing down to where Ruval fell, once he standing just above him Gallus conquered a sword made of black fire and raised it just above Ruval's head.
"Do you surrender?"
"Yes" Ruval replied weakly, and with that the sword disappeared and Gallus offered a hand to Ruval who accepted and thanked him for the match.
Serafall was beaming she was free of the Phenex Clan and free to marry Gallus, as soon as the fight was over she rushed to him and started kissing Gallus all over his face.
"Gallus you did it, I'm so happy" Sera said with tears in her eyes.
"I am too Gallus "said giving her the biggest smile she had seen on him before he turned to see her parents approach them.
"Well done Gallus" Lord Sitri said surprising Gallus as he was under the impression the Sitri head would be furious with him.
"You're not mad I won?"
"I was at first but then I realized that you wouldn't have done this if you didn't love my baby girl and I'm happy that she found someone who loves and treats her well" the Sitri head said with a smile.
"So does that mean?" Gallus started to ask but was stopped when Lady and Lord Sitri wrapped him in a hug.
"Welcome to the family"they both said...
Timeskip 20 years later brought to you by a chibi Gallus and Serafall in weeding cloths…
After 20 years of fighting it was almost over the Anti-Satan Faction had pretty much beaten the Old Satans as most of their armies would switch over to the Anti-Satan Faction after a loss. Gallus was sure that the fighting would be over within the year but was brought out of his thoughts by his wife's voice as she told him it was time to begin the assault on the last Old Satan stronghold that should end the was the assault on the Valefor territorys…
