The True Heir of Lucifer {Oc Male Reader X Highschool DxD}

The Stand for Peace

Diablo's Pov
I'm sitting at a table with my Mother and Ophis along with the Devil Kings,Micheal who has Irina,Azazel who has Vali,and Odin who has a valkyrie with him.We're disgusting what to do about the Khaos Brigade and then a Kurumi comes in and comes over to me and whispers something in my ear
Kurumi[Whispering]There's a large army of the Undead being lead by the Evil Dragon Yamata no Orochi heading this way there's about 590 thousand soldier.[My eyes wide tiny bit at the numbers]
Me:Thank you for the report,tell the others to get ready.[She nods and then leaves quickly the others see my serious face]The Evil Dragon Yamata no Orochi is heading this way with a army of the undead[They look surprised]
Azazel:How many?
Me:590 thousand[Their eyes widen with shock and fear]Ophis[She looks at me]We'll spear head the defense together [She takes my hand and smiles]
Ophis:Yes,My King[I smile]
Me:We need to gather all the Soldiers we can and get the civilians and children some were safe

[They nod and make calls to their people,Thor and a few other Asgardians god show up and 200 Soldiers,The rest of the seraphs minus Gabriel show up along with the decks including Micheal's and 500,Azazel calles the other Cadre Fallen-Angels and about 300 soldiers,Sirzechs and the other Devil Kings call their peerages and gather ruffly 600 devils ranging from Low-Class to Ultimate-Class,Rias,Sona and their peerages show up and Me and Ophis look at each other and nod.Ophis goes and calls one final man.They look curious and soon Great Red shows up and enter his human Form 

Red:How far are they out[I look at Kurumi]
Kurumi:About 200 miles out due Northwest[We nod and look that way]
Me:I can definitely sense them[They nod and I turn toward the Soldiers to give a speech before battle]Everyone[They look at me]The enemy is nearing closer and will soon arrive[I notice some look nervous and scared]Do not fear stand tall and hold your self higher than ever,for showing fear is only recognizing them as a worthy threat,but they are from it they only have strength from attacking the weak and manipulation the dead.A disgusting action for it spits in the face of all of are creators whether you be from heaven,hell,or somewhere in between,these creatures dare to threaten the peace that so many of are Brothers,are Sisters,and are Creators have given their lives and spilled their own and each others blood for.To let them win today is to tell all of those who have been lost that their sacrifice were nothing.I don't know about any of you but I for one Will not tolerate anyone disrespecting my fallen comrades in such a veil and disgusting way.So I ask what say all of you will you stand and fight with me and protect the sacrifices of are families and friends or will you turn your back on them.WELL[The entire army of soldiers cheer and let out a powerful and daring War Cry for their enemies head and I smile]THEN LET'S SHOW THAT PATHETIC DRAGON AND THOSE WALKING CORPSES THE STRENGTH OF ARE COLLECTED PEOPLE AND THAT WE WON'T EASILY![They release a massive Battle Roar and the other leaders come up to me all of whom are in their armor and fully equipped for battle,I smile and they smile right back we hear marching and turn to see them and I see Yamata no Orochi.]
Me:I'll kick the party off all right.[They nod I create a ball of Annihilation and raise it in the Air and it quickly expand more and more till it's about 666 feet in radius alone I then close my hand but leave one finger up and it condenses to the point of less then a inch in Diameter and point it at the army and then I speak some last words to the enemy]
"A True Prince Fights till their last breathe
 Not for their own benefits but for their people and their Soldiers that,
 Love them and their homeland,
 For the children who hold their dreams and light of the future in their eyes,
 And of course [I glance over at Ophis and my Girls]For the Women 
 Whom They wish to never see cry but only smile and light their way to happiness 
 and for those things I pray,to my father,to my grandfather,to my people, 
 to stand by my side and face future with me[Two Ghostly figures appear beside me and my mother begin to cry along with Micheal,Azazel,and the Fallen and Angels for they See my Father and Grandfather,They place their hands on my shoulders and increase the power of the attack by 500 times I shed a tear knowing who they are without even turning around]
I pray for Peace and Salvation for all,so that none may suffer,So that the tears of a Child who has lost their Father to the poison know as war never fall[I feel tears on my cheek]But you dare to attempt to ruin that which so many have died for so now you will die once more for the ultimate sin      

Me,Lucifer,God:The Sin Of Spreading the Curse Of War

Me: REPENTION [I fire the ball and a massive beem hits the enemy and I get flung back from the power from it being caught by Great Red.The beam goes and hit the enemy dead on and explodes in a massive explosion that send everyone to their ass

[The explosion]
[We look and see only about 700 of the enemy's forces are left along with a heavily damaged Yamata no Orochi.I don't waste any time and take flight going straight at Yamata.My people and are soldiers charge and begin to take out the remaining enemies.The Leaders join me with my mother,Red,and Ophis by my side we land right in front of the Evil Dragon.It looks at me with fear in it's eyes and pure utter rage]
Yamata:Your Rizevim Brother huh*Coughs up blood*have to admit your nothing like him
Me:Silence you overgrow Lizard you who hold no pride as a dragon who dare to call your self once shall perish this day[Yamata goes to talk but I shoot another ball of Annihilation at him and hitting him right in the face exploding his head we turn and see all the Undead dead on the ground I smile and we leave after burying all the dead.There were some injuries but zero casualties.I walk back to the Area were we started and once everyone returns and everyone's taken care of any injuries they had and we celebrate.I stand by Ophis and Scarlet comes over to us with Vali right next to her and she looks at Ophis and the walk over in the corner and talk.
Me:You have any clue what that's about?
Vali:Nope mom just said she wanted to talk to you about something and ask Ophis a question
Me:Hm okay by the way you okay[He nods]also I notice you and the young Nabieral  Heiress have been getting along very well and the Bael Heir[He blushes slightly]Do you like her Vali?
Vali[Blushes]Well,I um.....[Notices my pure curiosity with no ill intent in it]Yeah I Honestly think I'm in love with her.
Me:[I smile and put a hand on his shoulder]Then tell her Vali[He looks stunned and scared]Trust me if what I've heard from Rias and Sona is true she like you back a lot[He looks surprised and nods
?????:Vali[We turn and see the young woman who call him]

[The Young Heiress of the Naberius House Shiki Naberius the same age as Vali]
Vali:Ow Shiki hey [She notices how nervous he  is and she blushes I chuckle]
Shiki:Um hey Vali I was wondering something[Scarlet and Mother both begin to listen in and Vali Nods]Would you um....Go ....on a um........Date with me[Vali goes wide eyed and she looked nervous I nudge him and he snaps out of it and goes up to her and lift her chin she looks into his eyes and they kiss,everyone in the room stops and notices I smile widely,Shiki wraps her arms around Vali's neck and He wraps his arms around her Waist and They kiss passionately and with pure love for each other.Once they separate everyone in the room myself included just clap and they turn and see all of us and they turn redder than the Gremory's hair and I walk over and hand Vali a key
Me:This is the Key to the Lucifer's Family beach house you can use it.[He takes the key and I decide to have a little fun with my nephew]Just remember to buy protection okay [They turn even redder and quickly thanks me and leaves.Then Scarlet comes cover to me and I look at her and says something that surprises me]
Scarlet:Diablo[I look at her]Would you be willing to become Vali's Father
Me:You mean marry you[She nods and I smile]You'd have to share me are you okay with that[She nods and I lift her chin and Kiss her]Then I'd love to have a beautiful woman like you and a amazing Son like Vali[She smiles and all the girls come up and welcomes her.
That night was filled with joy and celebration]
