As Riser gets stronger by devouring Gasper from the future, Issei also becomes stronger due to his combination with his future self.
Yet, Riser had to say that this world was quite unfair. While he needed to do something tedious and even life-threatening, this guy became stronger due to a chance. Moreover, what was this?
"I WON'T FORGIVE YOU, RISEEEERRRRR!!!!"
Issei, who had combined with his future, rose once again and started his attack.
DDD.
Diabolous Divine Dragon.
This was his most powerful form.
The combination of current Issei, who had the body of a god, and his future self, who had the boy of the dragon and the devil, created a powerful combination. Moreover, along with the experience and bravery that came with his future self, he had become so dangerous that he could even destroy this world.
What is even more dangerous is his anger, which fueled his power and also made him even stronger.
Nevertheless, facing this anger, Riser was confused. Why did he do it? Did he do something wrong? Why did Issei suddenly come to him from the future and say that he wouldn't forgive him?
As for the original Issei?
Did this idiot forget that he was trying to take his former fiancee?
Was Riser wrong to fight for his rights?
In the beginning, no matter how ugly they were, Rias was his fiancee.
Did Issei think that he could take Rias without angering him?
How unreasonable!
Nevertheless, Riser didn't underestimate Issei since he knew that Issei had combined even stronger, so strong that Issei's existence was so bright.
At that moment, Issei was like the brightest light in the abyss. He was an existence that led everyone during their darkest moment.
But Riser?
He had become evil, the one that plunged this world into misery. Nevertheless, it didn't matter since he had gotten used to the role of villain. Even though he knew that he wasn't a villain and he just wanted to live well, he was portrayed as evil in this world.
Yet, it didn't matter since being evil gave him everything, and he didn't lack anyone who believed in him.
So, even if Issei appeared in front of everyone, it was hard for one's heart to be swayed by Issei's existence except for those who had a bad relationship with Riser.
As for those who had a great relationship with Riser? All of them were solemn, wondering how to help Riser.
Yet, Riser didn't need their help. Even though Issei might have become stronger by combining the power of the Red Dragon Emperor, Chichigami, Ophis, and the Great Red from another world, he didn't fear this guy!
Taking out the True Longinus, Riser moved with the speed of light, charging with the intention to kill Issei in one go!
Facing Riser's vicious attack, Issei was startled by the future, but it was too late!
At that moment, Riser's brightness wasn't even lost to Issei. His existence was bathed in the holiness that shouldn't appear on a devil, yet it appeared on him.
Issei might have combined himself with Chichigami, a god from another world, but Riser had devoured the God of the bible. The strongest Longinus, True Longinus, held the soul of the god of the bible, and he directly devoured it after he had gotten the "Holy Affinity" from Irina previously.
"O Spear. The true Holy Spear which pierces through God.
"Suck the ambition of the King of Domination sleeping within me and pierce through the gap of blessing and destruction.
"You. Announce the will and turn it into a glow.
"True Idea."
At that moment, Issei felt death was near, but due to sheer coincidence, he was able to dodge it like a bug. The time seemed to stop and rewind, and his action to dodge somehow couldn't be done, erased before his body was stabbed by this holy spear.
Riser used the power of Desperado, erasing all the coincidences, fate, and many others, leaving only a result where Issei was dying at his hands!
Issei widened his eyes, and he was in disbelief!
"HOW?!"
If it was a normal villain, they would be proud of his action and would arrogantly tell why the hero had lost.
Yet there was no such thing on Riser.
Riser was going to kill Issei!
No one could stop him!
Nevertheless, the world didn't want Issei to die, and somehow a circle-like portal appeared and then sucked Issei, so Issei wouldn't die along with summoning a powerful creature from another world!
When this creature appeared, Riser ignored the presence that made everyone tremble with fear and killed it directly.
Yet, this single moment gave Issei a chance to escape, and somehow, everyone also appeared as if they were called into this place.
"DEAR!"
"DARLING!"
"LUCIFER-SAMA!"
Everyone was looking at Riser with concern before they were all dumbfounded, looking at Issei, who had somehow appeared once again.
Nevertheless, watching everyone there, Issei's expression became gentle, and then he shouted, "RISEEEERRR! I WILL COME BACK! I WILL SAVE THIS WORLD! I WILL SAVE THIS WORLD FROM YOU! YOU EVIL! YOUR TYRANY WILL DEFINITELY END! FOR SIRZECH-SAMA, AJUKA-SAMA, AZAZEL-SENSEI, AND EVERYONE! I WILL AVENGE THEM!"
His shout was so loud as if he was afraid that no one would hear him.
Yet, Riser was as calm as ever and had just thrown the True Longinus, who had escaped from another world, into Issei.
"?!"
Issei was startled, and others also quickly tried to close the portal while trying to erase the connection of the True Longinus with Riser.
However, it was impossible.
As the portal closed, the True Longinus kept chasing Issei, but Riser knew that it was impossible to kill Issei with it, so he might as well destroy it.
In another world, the True Longinus was detonated by Riser.
*BOOOOOOOOOOOOOOOOOOOOOMMMMMMMM!!!!*
Yet, even so, Riser knew that it was impossible to kill Issei with that. However, he knew that it should be enough to kill many of the beings in another world.
Still, the words that were shouted by Issei carried a magic-like effect, similar to brainwashing that would believe his words, which made many think that Riser had done something evil, yet under Riser's aura, those thoughts disappeared.
Even if Riser was evil, so what?
They were comfortable under his role, and all of them loved him.
Moreover, even if they knew Riser was evil, was it even a problem?
After all, they weren't his opponent, and he could kill them anytime.
As for Issei?
This guy who had run away, was there even a need for them to think about him?
Still, those who were still unconvinced by Riser had a seed of doubt, and they waited for Issei to return to this world to bring the world into the righteous!
Nevertheless, even if Riser knew that he was still as calm as ever and called every one, he knew the end of his war would be soon.
