Battle between the leader of the Fallen Angels and the Grigor and Sebastian the man who possess the Chaos Eater who defeated Razziel and other people he had to fight to get to him now they will lock swords together while the others who are watching this remains hidden and waits for the time to strike, Rias already revealed herself on the cliffs looking at the fight between them while Akeno, Vali and Xenovia stands ready just in case Sebastian needs their assistance but the way this is i don't think he would be needing some help to fight him.
Sebastian was struggling fighting him when they keep colliding their swords together and moving back away, Sebastian knows that he is holding back and just teasing him so he wraps his sword in red energy and charges but he would take flight in the sky and Sebastian follows him trying to swing his sword up at him but he missed twice already while he just laughs at him making him mad he continues chasing after him in the sky but then he would charge down grabbing Sebastian's neck and flying back down faster than before sending Sebastian down with him but the moment they were close to the ground he would let go of Sebastian while he flies away letting him crash through the ground while he stands on the cliff near Rias.
"Enjoying the fight Rias Gremory?" he looks over to her, she would take a step back but she stands ready to fight "You don't stand a chance." He looks to Sebastian and he swings his sword to block Sebastian as he charges from the smoke clashing against his sword again but he would smile as he looks down at Sebastian
"You shouldn't fight me Sebastian... i am not the real threat here."
"I know you want to go after Rias... so forget it!" he kicks him back and looks over to Rias "Get out of here." He looks over and charges towards him yet again clashing against his sword but then he would push Sebastian back and swings to the side giving him a horizontal cut on his chest.
Sebastian ignores the cut then moves back holding his sword with two hands in front of him, the leader of the fallen angels would lower his sword "Sebastian we should be on the same side... you are just a pawn to the devils and a pawn to Sirzech."
"Just shut your mouth... i am not gonna do what you ask me to so forget it, just shut up and lets fight."
"Oh you are such a fool..." he shakes his head "I guess Sirzech never said anything about your parents."
Sebastian charges and clash against his sword yet again "What do you know about my parents..." he looked very serious this time, he was able to push the angel leaders blade back to him but not close to cut him.
"Your father was the human's greatest champion... after he killed the red dragon he was ready to rebel against the other species... who do you think triggered this rebellion?" he moves to the side to let Sebastian run past him then he strikes his back and kicks him against the wall then throws his sword at him impaling his chest with it "Do you know about his death as well?"
Sebastian coughs out blood; he grabs the blade then hears Rias calling his name out loud. "Stay back Rias..." he looks back to him and gets punched to the face by him causing him to spit out blood on the ground.
"Do you know the one who killed your father... do you know the man who betrayed him and cut him down to prevent the next great war..." He grabs Sebastian's neck as he moves closer to his ear to whisper the name of the man who killed his father.
"Sirzech Gremory."
Sebastian froze for a moment when he said his name, his eyes wide for a moment then he pushes him away and pulls the blade out of his chest "You're lying!"
"I was there when it happens... Sirzech and your father were friends in the war, he sided with the devils to take out the red dragon but once his back was turned Sirzech send the final blow to kill him and preventing the rebellion against the races."
"No... You can't be right... like i would ever believe a word you say!" he raises his sword but then he gets another cut to the hand causing him to drop the sword to the ground then he gets hit across the face, hitting against the wall again.
"You are not good enough then... i told you the truth and you won't believe in me..." he looks over to Rias "Am i wrong Rias?"
Rias stood there remaining silent as she looks at Sebastian with a sad look, she shakes her head when Sebastian looks up at her as she knows he is telling the truth "I'm sorry..."
Sebastian stood there for a moment as he leans against the wall then the angel leader would punch Sebastian yet again to the chest causing him to sit against the wall then gets impaled again by his sword to the leg causing Rias to charge towards him, he would turn back and swings his blade but Rias would summon a black and red pentagram in front of her to block the swing, it shatters and causing Rias to take half the damage, she flies back and falls to the ground but she slowly gets back up.
Sebastian just sits there slowly looking up seeing Rias falling to the ground then getting back up, the angel leader would hit Rias across the face to send her to the ground once again, Sebastian started to get more madder as he watches this fallen angel hitting her around like she was nothing and she would take all this damage just to save Sebastian. Finally he would just wrap this up by stabbing his sword through her, causing her to freeze and so does Sebastian, he pulls the sword out of her and she falls to the ground but not getting up this time, because of that darker red energy would start to come from the Chaos Eater and would wrap Sebastian in darker red flames into a flaming pillar. The leader looks back at Sebastian and smiles as he knows whats going to happen.
"It's true... he is the Arch Devil..." he said to himself and takes a few steps back then takes flight and lands on the high ground to watch his transformation.
Rias would open her eyes and watches the flames consuming Sebastian, she closes her eyes then Akeno appears near her and gets her out of there before the flames dies out, the others hidden would vanish over to Rias while Akeno tries to heal her would she sustain but they would look back and watches what is about to happen soon.
The flames dies out quickly and Sebastian stood there looking down, his skin was red like blood, all he had on was his black armour lower part of his body, his hair was longer than before and his spike horns was longer facing forward.
"The Arch Devil... the rarest devils ever... i knew you were the one... and a male Arch Devil also, now there are three of them." He said looking down at Sebastian
Sebastian would take a few steps forward then suddenly he stood in front of him and grabs his face, throwing him off the cliff and crashing to the ground, he jumps up and looks up to Sebastian then he moves his hand to the side and his sword would come to him by flying in the air, he grabs the sword and place it on his shoulder ready to give him a serious fight.
Sebastian would charge towards him but he jumps back while Sebastian swings the ground causing an explosion thanks to his swing of his blade as it was at its true form, he continues chasing after him and tackles him against the wall, he grabs his hand that was holding the sword then strikes through his arm and his wings with one swing of his sword, he would yell in pain for a moment then gets punched to the side of the face to send him falling to the ground while Sebastian yells out loud in the sky.
Rias gets up sitting next to Rias looking over to Sebastian "How is this possible... is that even Sebastian?"
"He has become the Arch Devil, the rarest devil in our race, he is the first to become a male and i know two female Arch Devils hidden among us." Akeno said while watching Sebastian
"The three Arch Devils... just like the Arch Angels..." Rias said to Akeno
The Fallen Angel Leader gets back up and summons his spear, his wings appears back on his body and looks over to Sebastian "He is getting serious."
Sebastian charges down with two hands to his sword, once he got in front of him he swings his sword, letting go of the handle with one hand to it trying to strike his face but he missed, he jumps back and then charges towards him swinging his spear and clashed against his blade but Sebastian grabs his neck then kicks him away before charging to swing down on him, striking his chest a bit but didn't go deep enough, once he takes flight Sebastian gives chase by grabbing his wings and slamming him back on the ground then finishes this off by stabbing his sword through his chest, leaving his sword inside him while he takes a step back and watches him slowly dying.
"Sebastian..." he said while trying to pull the sword out but can't, he raise his hand to him then coughs out blood "... Remember... Sirzech... did this... don't be their lap dogs..." he soon moves back letting go of the blade; his body would start to burst into flames until there is nothing left of him. Sebastian pulls the sword out of his body and place it on his back, soon his body would start to go back to what it was before without the Arch Devil side.
Sebastian stood there for a moment and Rias would get back up slowly walking over towards him, Akeno would stand there looking over at the two but once Rias got closer to Sebastian he looks over to her and backs away from her.
"Sebastian..."
"You knew and you didn't say anything to me... you used me to get to the Slayers, destroy them..."
"Sebastian i didn't know-"
"You knew Rias!" He raise his sword in front of her "And now i am going to finish this once and for all." His wings spread and then he places his weapon away before taking flight and flying over to the citadel where Sirzech is at the moment.
"Sebastian!" she yelled at him while he flies off "Oh no... brother..." she soon takes flight but then she started to get pain from her wounds, causing her to go on her knees
"Rias you can't go i haven't finished healing you." Akeno runs over to her and crouches down to her
"I have to... before he kills me brother..."
Sebastian was coming with a vengeance to Sirzech as he was the one who killed his father and his mother. Sirzech stands in the room where he was talking to Sebastian before, he stood there looking out at the window with Grayfia and both of them would notice that Sebastian stands behind them holding his sword tight ready for a fight.
"Grayfia could you please leave the room for me." Sirzech said while still looking out the window
"Ok darling, be careful." She turns back looking at Sebastian while she walks out of the room and closing the door
Sirzech looks over to Sebastian and he takes a step forward "I know what you did Sirzech... you used me... you used me to kill the Slayers... you killed them!" he aims his sword at Sirzech while he just stands there
"During the war he did kill that dragon but he was plotting to go against my kind and the others, i had no choice, he force me to kill him and then his wife got involve and i had to kill her also... didn't i tell you i didn't want to see another great war, that is why i wanted the war to hold-"
"Rias and me... you wanted me to become your soldier, to become your pawn... did you get Rias into bumping into me long time ago!?"
"He never told me that he had a son... i only knew about your existence a year ago thanks to Rias... your moment with Rias is real and she feels the same but she knew about the death so i told her to keep it a secret until the slayers are dead."
"You forgot one thing... i didn't kill all the slayers... there is one more who can stand in your way and that's me." Suddenly his skin turns red again turning into the red arch devil once again
"The Arch Devil..." he said to himself then he raise his hand in front of him and suddenly his sword appears, a long sword with red markings all over it, he held it ready "Very well then... if you are going to be like this then i will have to kill you."
"Sirzech!" he charges towards him with one hand to his sword once his transformation is complete, he swings down at Sirzech while he swings up, once they collide they cause an explosion inside the room, causing Grayfia outside to worry a bit but she hides it from everyone but she knows that he can defeat Sebastian.
Both of them flies outside still had their swords collide, they continue going until they land away from one another when they hit the ground. "You really want this don't you Sebastian..." he held his sword with two hands
"You're going to die, let the world burn it's not my problem anymore." His sword lights in red flames and charges towards Sirzech
"So be it." He swings forward causing another explosion outside.
Rias and Akeno made it nearby and spots the fight "What have i done..." Rias said to herself as she watches the battle between Sirzech and Sebastian, this could be his last fight in this world even if he does win or lose he will get what he wants, vengeance for what Sirzech has done to his family.
