A few minutes before Sirzechs Lucifer announced the match.
Grayfia: I'll tell you the rules of this duel firstly it's not allowed to kill your opponent, secondly if one of you says 'surrender' your opponent will be declared absolute win you understand.
Arthur & Issei: We get it.
{I decided to rename Riser Phenex to Arthur Pendragon Alter because after this the body Arthur Pendragon took would....become his Fate Prototype/FGO version. But all DXD characters will still call her Riser Phenex during dialogue/talk.}
Grayfia Lucifer turned around and prepared to create a teleportation circle, but before Grayfia left the arena. Arthur said to him.
Arthur : Tell your husband if Hyoudou Issei wins this match I will agree to annul his marriage to Rias.
Grayfia and Issei were shocked by what Arthur said. Grayfia then told the two people "Good luck".
Issei: Why are you saying such cute things in front of a squirrel!?
Arthur : I'm just saying if you win but if you lose you have to accept the fact that I will marry her do you understand, Hyoudou Issei!
Issei was starting to get annoyed with him and he was sure to beat him black and blue. After Sirzechs Lucifer declared that the match had started, Issei activated Boosted Gear and Issei said "Balance Brecker". Lancer in another world
so Arthur decided to avoid all of Issei's attacks which were just hitting all over the place. Only from that Arthur knew that Issei had no fighting experience. Issei was getting more annoyed that Arthur was only dodging and blocking his attacks not trying to attack him as if Arthur could attack him whenever he wanted.
Issei : Where did you say that you will fight seriously. You just keep dodging and enduring my attacks, if you're not in the mood to fight me, why not just give up!?
Arthur: You really like to talk a lot.
Issei: YOU.....!? Welsh Sonic Boost Knight Boo, boo, boo, boo, boo, boo, boo, boo, boo, Boosted!! Welsh Dragonic Rook Feel this Riser....!!!
Issei runs very quickly with Welsh Sonic Boost Knight mode then at that moment Issei fills the Boosted Gear with double the power in the gauntlet and Issei switches Welsh Sonic Boost Knight mode to Welsh Dragonic Rook mode and finally hits Arthur from the right very hard until Thrown from where he stood and crashed into the arena wall. Not only that, Arthur's face had a burn on his right cheek. But Arthur smiled slightly while there was still smoke so no one had a smile on his face.
Everyone who watched was impressed with what Issei showed them and everyone who watched felt worried about Riser Phenex for fighting Issei. inside the Phenex mansion the Rias pieces were happy because Issei managed to hit Riser Phenex.
Asia : See what I said Issei-kun must have won against him.
Akeno : Ara~Ara, Issei-kun I'm not cloudy you can hurt him.
Kiba : So won't the regeneration ability work if he gets hit with salt and holy water?
Sona: It's not that it doesn't work, it's that it's ability has decreased because no matter how great the regeneration is, it's still a demon that's weak against holy energy/holy elements. Whatever the outcome of this match is Hyoudou-san will win.
Koneko : It's the Phenex chicken's fault for helping that pervert gain power.
Asia, Akeno, Kiba, Sona : Right.
On the other hand, Riser Phenex's family was enraged by the words of Rias's pieces. But Lord and Lady Phoenix couldn't let out their anger here there were 3 of the 7 great demon lords, but Rias's feeling of uneasiness still didn't dissipate and was getting worse. Lady Gremory approached her daughter.
Venelana: What's wrong my daughter why do you look so restless instead of feeling happy because one of your pieces managed to defeat Riser.
Rias : I'm happy that someone managed to beat him up, but somehow I had a feeling something bad was going to happen to Issei and for some reason I started….... it's okay mom.(bows head down).
Venelana realized before her daughter finished talking to her that her daughter's face was a little red on both of her daughter's cheeks. Venelana mutters in her mind "Ohh geez, my daughter's love life is really confusing she said that she didn't like Riser until now and now when Riser is about to lose she starts to love him!, gosh." and returned to his seat. Back to the arena where Issei is currently attacking non-stop with Dragon Shot non-stop.
Issei: Kiba said "don't let the enemy get to the chance to attack." Koneko-chan said "give full strength when attacking the enemy." and Akeno-san said "focus all your magic power to strengthen the attack." Welsh Blaster Bishop, with this done!!!
Just as Sirzechs was about to finish this match, suddenly from the direction of the wall someone came out of the acid so fast that even everyone who was watching this match couldn't see who was coming out of the smoke. At the same time Issei was thrown very hard onto the chess piece tower in the area. The figure that threw Issei was Arthur Pendragon in a state of severe injury to the point where blood was still flowing out of Riser Phenex's body which he had taken by Spirit Arthur Pendragon who had merged with himself from another world.
Arthur Pendragon: You have fast attacked this body because WE already know all your strengths. WE will start the warm-up so get ready Hyoudou Issei!
The entire audience was shocked by this situation because they were all sure of such a barrage of attacks and her regeneration ability had weakened and Riser Phenex definitely couldn't stand back up, but they were all wrong Riser Phenex stood back up even though his body was badly injured and didn't recover from Issei's continuous attacks. When Riser Phenex spoke the audience was even more surprised because they heard two voices from Riser Phenex but all the leaders of the five races were confused and curious about the word "We" the race leaders were curious about what Riser Phenex said
.
Amaterasu: Why did he say the word "We" there must be something in that word.
Michael: It's like he's saying that he, fighting not only alone. This is really weird and I feel the other voice is very familiar.
God Odin : The demon boy way of speaking is like saying he will be reborn this but is it possible.
God Zeus: I can't believe that there is nothing like that in this world, did this happen because he had....
Azazel: Hahaha.... This is really interesting I thought it would be an opening for the new owner of the Boosted Gear but I was wrong. Hahaha..... this is really very interesting!
After Riser Phenex spoke a huge flame from Riser Phenex's body burst out, but the flames that came out were not ordinary flames as the flames were black and red like blood which began to envelop Riser Phenex and quickly ennobled his body which was full of wounds with an unparalleled speed. sense. After his body had recovered Riser Phenex began to snap his right hand's fingers, then a reddish-black and slightly golden enormous energy made everyone who was watching this match completely shocked again by this situation beyond their thoughts. Still in the underworld all the devils felt that extremely abnormal energy and trembled in fear because they felt that great energy. At that time the three Demon Lords spoke.
Sirzechs : Where does Riser Phenex come from with that much energy!?, and it is the destructive energy of my family!?
Serafall: I'm also curious why he has it especially since the destructive power is so dangerous.
Ajuka : Sirzechs, Serafall did you guys feel it too...?
Serafall: Of course Aju-chan both of us felt the enormous destructive energy.
Ajuka : That's not what I wanted to say but the holy energy I slightly sensed from the Riser Phenex.
Sirzechs & Serafall: What.....?
The huge energy kept pouring out from the Riser Phenex and rising again up the red like a Pillar, then little by little the energy pillar started to dissipate after the huge energy kept disappearing, but they didn't see the Riser Phenex anywhere. Instead of an 18 year old male with a height of about 181cm, wearing a black with red trimmed knight's attire and armor wearing a blood red hood with black trim, everyone watching wondered who the mysterious man standing in that area was.
Issei: Who are you and where did that Phenex Bastard go!?
Arthur (Alter): I'm in front of you, can't you see with your eyes anymore?
Issei and the audience were surprised by the mysterious man's statement because the young age was around 18 or 19 years old while Riser Phenex was around 20 or 21 years different, yes only 1 or 2 years younger. When Arthur (Alter) opened his hood and showed a very handsome face more than Kiba, half of the female audience blushed because of the handsomeness of this man with golden yellow hair and golden eyes. What makes Arthur (Alter) look firm and dignified like a king.
Issei : Are you really that Phenex bastard, but no matter how you look I will beat you and become Harem King.
Arthur (Alter): You can say that after you beat me then you can be arrogant do you understand.
Issei returns to using the same method when he managed to hit Arthur (Alter) but this time Issei will hit split left, Issei changes his Balance Brecker form to Welsh Sonic Boost Knight and moves Sonics speed while filling the power in Issei's left hand, then changes again to Welsh Dragonic Rook "With this your story is finished Riser Phenex." that's what Issei thought. When Issei almost hit him. Arthur (Alter)'s left hand withstood a blow from Issei was shocked by what happened because Arthur (Alter) managed to withstand an attack that he had increased 10x stronger than the first, when Issei pulled his left hand but couldn't let it go from Arthur's (Alter) left hand Issei kept trying to remove his left hand from Arthur (Alter) but he couldn't let go. Arthur (Alter) focused magic energy on his right hand and punched the huge armor right in the chest with his right 'Boom' The fist pierced through the Welsh Dragonic Rook's armor and it shattered into pieces Issei started vomiting blood as the fist hit his chest, giving no chance to Issei recovered slightly Arthur (Alter) grabbed Issei's head with his left left hand after grabbing Issei Arthur's (Alter) head and directed Issei's head to the armor on his knee so hard that his nose and one tooth were broken by hitting Arthur's (Alter) leg armor. Issei's condition really provided that even Issei couldn't see properly and couldn't stand properly he was completely dazed by Arthur (Alter) when his right hand Arthur (Alter) wanted to summon his soul weapon. Sirzechs Lucifer said "This match I have declared Riser Phenex as the winner."
{I said that I will use the name Arthur Pendragon, right, but I just remembered that it is Characters with the same name, so I will use the name Arthur (Alter) for the next dialogue}
