Rizevim was confused but just then, Seekvaira's voice rang out from the sky.
"——Awaken, Founding Ancestor. King of the Dragon Gods that is an Army in itself. Tiamat!"
After the password of Tiamat was spoken aloud by her while drawing a red-colored sword with black and gold details called the Sword Device into the sky.
Her beautiful figure that was now flying with devil wings on her back was enveloped in several gold-colored magic circles.
Instantly, a suit of armor that mimicked the Legendary Dragon, Tiamat from another world appeared and became an extension of her body.
To the eyes of others, Seekvaira appeared to be riding a seven-meter-tall red Gundam with an elegant design and the crown on her head made her look like a Queen who looked down on everyone.
"What is that?" Rizevim subconsciously asked, there was curiosity in his eyes towards something that was clearly not of this world.
The oppression Seekvaira emitted didn't help either, it tickled his body as her power seemed to have surpassed that of an ultimate-class devil and even the current Four Devil Kings!
But instead of fear, he couldn't help looking at the Divine Drag-Ride Tiamat with greed in his eyes.
"That's the toy from another world that I gave Seekvaira."
"Another world?! And you call that a toy, Eiji?"
Rizevim was stunned, he suddenly regretted being born a male.
If he was a beautiful woman, he might be able to seduce Eiji into giving him toys from another world.
Fortunately Eiji didn't bother to read Rizevim's mind. Otherwise, he would feel disgusted and kill him right away.
That would be boring.
"Instead of worrying about that, you should worry more about yourself, Rizevim."
Eiji casually said while eating the dried fish snack from Koneko's hand. The beautiful cat girl sat quietly on his lap, and pressed his younger brother with her body.
Koneko narrowed her eyes coquettishly when she felt something hard poking her butt.
She pretended not to know.
Tsk!
Rias and Akeno regretted not moving faster to sit on Eiji's lap.
"....." Rizevim and the others.
Aren't you two too relaxed?
On the other side, seeing a group of Evil Dragons flying towards her, Seekvaira was very calm.
"Blade."
A sword suitable for Tiamat's size appeared in her hand, although her body was currently large, she moved extremely fast in the air and her figure left a golden line with sparks of lightning in the sky.
In an instant, she cut more than a dozen Evil Dragons into two pieces and then— "Breath Gun."
Tiamat's main long-range weapon appeared and replaced the sword in her hand. The weapon was like a pressure gun that could produce high-temperature fire, she fired it at the Evil Mages and Evil Spirits that were swarming around Arthur and Bikou.
Immediately, what looked like dragon's breath with yellow-colored beams burned all creatures within its range to ashes.
Seekvaira then directed the attack towards the sky where hundreds of evil dragons were flying in groups.
Within seconds, they were all annihilated by her as well.
The scene made Rizevim sweat with worry, the army he had gathered over several months was starting to dwindle very quickly.
"Hiss! Even from here, I can feel how hot the attack is! Be careful not to accidentally burn us, Heiress Agares!"
"Bikou, you'd better not upset her with your words."
"Oh Arthur, you're right. I don't want her to deliberately target me."
"....."
Arthur wanted to silence Bikou's very noisy mouth.
He glanced at Seekvaira's figure flying in the sky and wondered what weapon she was using?
It was very strong.
Of course, what everyone didn't know. The attack that Seekvaira had just unleashed was stronger than the fire breath attacks of the Heavenly Dragons, especially the Red Dragon Emperor, Ddraig.
[This is quite surprising. The power of the Divine Drag-Ride Tiamat that Seekvaira was currently displaying was clearly stronger than the original work. Maybe it was also because she was not a human, but an ultimate-class devil with a higher upper limit than Lisesharte.]
[In other words, the maximal power of the Tiamat from that world is not inferior to the Heavenly Dragons in this world and Seekvaira is capable of using it.]
Hearing Eiji's inner voice, Seekvaira felt proud and pleased with what he said.
That was definitely a compliment to her.
But who is Lisesharte? It sounded like the name of a beautiful woman.
The other heroines were also curious although they had a guess that Lisesharte was...
[One of the heroines in the original work, Lisesharte Atismata was even only able to use Tiamat's Divine Drag-Ride for ten minutes. Beyond that, she won't be able to control Tiamat's power.]
[Worthy of being my woman, Seekvaira is certainly better than her.]
Sure enough, it was a heroine!
While Seekvaira felt sweet in her heart and continued to annihilate every Evil Dragon and Evil Spirit that seemed to come out of the Agreas Dome.
Before she thought to aim her Breath Gun at that place.
"Niðhöggr!"
Rizevim suddenly shouted the name of an evil dragon famous in Norse Mythology.
A black Eastern Dragon about 20 meters long that flew out of the Agreas Dome.
Despite his snake-like appearance, he had four legs and four wings. He also had terrible saliva from his huge mouth.
Seekvaira frowned, she looked at the creature in front of her with disgust on her beautiful face.
"Devil, you look delicious. I'm going to eat you!"
Niðhöggr had a voracious personality as he was always hungry and devoured whatever was in front of him.
Rizevim even had to seal him away before he wanted to use him like now.
His power was stronger than all Dragon Kings including Tiamat (DxD) in the past. Seekvaira knew this and simply switched her weapon with another weapon.
"Seven Heads!"
This time, a long-barreled cannon with seven muzzles connected to her right arm and shoulder appeared.
It was Tiamat's other main armament which in the original work was powerful enough to kill Ragnarok.
However, when Seekvaira used it, it was clearly many times more powerful. Before Niðhöggr could pounce on her, the Seven Heads in her hands shot out a beam so large that it swallowed her target's massive body whole.
*BUUZZZ!!*
Niðhöggr was not even able to scream as he was annihilated instantly. However, the beam Seekvaira fired continued to fly in a straight line and split the clouds in China and other countries.
It did not hit anything other than Niðhöggr before disappearing. Otherwise, its power was enough to destroy two or three countries.
Rizevim's legs became a little limp, he looked at the scene in front of him in disbelief.
Eiji wasn't even doing anything but sitting and watching, but a young devil like Seekvaira was more than enough to wipe out almost half of his total army and one of his trump cards, Niðhöggr.
"Seek-chan must be having fun with his new toy." Rias said with an amused smile.
"Fufu. I'm suddenly curious... Eiji, do you have any other toys?" Akeno asked while rubbing her lover's shoulder coquettishly.
[Akeno, are you sucking up to me? I must say in my heart, I'm happy to see you like this.]
You're happy? That's good.
Akeno's slender fingers began to massage Eiji's shoulders, many male students at Kuoh Academy would definitely be jealous of seeing the most famous Yamato Nadeshiko (ideal woman in traditional Japanese culture) in their school serving him like that.
There was also Koneko, she was feeding him with her own hands.
"Ehem! For now no, I mean there's nothing suitable for you, Akeno. Wait until I get something good from the other world again."
"I'll wait~"
Akeno whispered and exhaled her flower-scented breath at him. Eiji rubbed his nose, but feeling Koneko and Rias' gazes, he also said, "Of course, the same goes for Rias and Koneko."
"Oh~"
"Meow~
The two girls were satisfied to hear what Eiji said.
It must be said that unlike the beta protagonists in those novels, he had a very high EQ and was sensitive to the feelings of his women.
No wonder his harem continued to grow without knowing limits.
"....." Gasper and Yuuto.
They felt like a light bulb that was illuminating Eiji and his girls who were flirting with each other.
Vali also felt the same way.
He didn't even realize that Rizevim's demonic power was no longer suppressing him and continued to watch what was happening without attacking him.
Inside the Divine Dividing, Albion complained and said, "Vali, why are you doing nothing? This is your chance to sneak attack!"
Unfortunately, the effect of the Sacred Gear Canceller was still in effect and his host could not hear his voice.
"Eiji, do you mind if I try to stop Seekvaira?"
"No, you can try. As long as you are able."
"You can't take back your words!"
Rizevim immediately opened his wings and flew towards Seekvaira.
As for his grandson? He didn't care about him anymore.
As long as Eiji did not interfere, he was still a little confident to stop Seekvaira with his abilities.
Sacred Gear Canceller was just a name to intimidate Sacred Gear users. In fact, it was the ability to obliterate the characteristics and abilities of any artifact.
At least so far, Rizevim did not know the limits of his abilities. So, he was a little confident!
Of course, he also had to be careful not to hurt Seekvaira so that Eiji wouldn't get angry and immediately mess up his plans with his power.
"Seekvaira Agares, stop right there! Hey, I said stop!" Rizevim shouted with a helpless expression.
Seekvaira who was shooting at every evil creature that came out of the Agreas Dome frowned.
She stopped squeezing the trigger of her Breath Gun, and looked at the son of Original Lucifer without the slightest respect.
What was she doing it for?
That middle-aged man had clearly become an enemy of the Alliance and a big villain in the entire supernatural world.
"Rizevim, do you want to use your strange ability on me? Do you think you are capable of it?" Seekvaira knew about the Sacred Gear Canceller.
Or rather, everyone on the Alliance side knew about it.
Only someone like Vali had dared to use his Sacred Gear in front of Rizevim and ended up miserable because of it.
"You guessed it. I admit you are very strong, but you are still too young and underestimate this old man."
Rizevim had a rare serious expression on his face, demonic power exploding from his body.
He released a barrage of demonic power waves at Seekvaira and at the same time, he teleported behind her and tried to touch her Gundam with his hand.
"Don't touch my Gundam with your dirty hands!" Seekvaira said coldly.
She activated her special ability as the devil of the Agares family, Time.
Rizevim wanted to complain and say his hands were clean. But right now, he was frozen and his body was enveloped by a round light blue barrier.
The barrier had the ability to stop time for whoever was inside it.
In the past, Rizevim was able to ignore the devilish abilities of the Agares family with only his demonic powers and was not afraid of them.
But now?
"...!" He was terrified because Seekvaira's ability was stronger than he thought.
No, I can't die here!
I haven't even gone to the other world to create chaos there!
Rizevim was screaming madly in his heart.
He was going to die because of his arrogance.
"Farewell, son of Lucifer."
Seekvaira aimed the Breath Gun at Rizevim and was ready to burn him to ashes.
At that moment, a silver figure crossed the sky and approached them before shouting, "Stop! Agares Heiress, only I can kill Rizevim!"
[Who else but Vali in his Balance Breaker mode? He has a grudge against his grandfather, Rizevim and won't be satisfied if he lets someone else kill him. But more than that, I feel like he likes to steal others' prey at the last moment.]
[For example, in the original work, he prevented Kokabiel from dying at the hands of the protagonist Issei and he did the same to other villains for various reasons.]
[I wonder what Seekvaira will do?]
Hearing what Eiji said, Seekvaira blinked her eyes and aimed the Breath Gun at Vali.
"You..." Vali widened his eyes. This woman was really going to attack him?
"Rizevim has stolen Agreas from my family's territory, I came all the way here too to kill him. Vali Lucifer, do you mind?"
"Of course! I—"
Seekvaira was too lazy to listen to the White Dragon Emperor's ramblings at the moment and used Tiamat's other armaments.
Legion.
It consisted of sixteen giant arrowhead-shaped throwing weapons. These weapons were self-propelled and remotely controlled.
Each of the weapons fired a beam at Vali.
{Vali!}
"Shit! Divide! Divide! Divide!"
Vali stretched out both of his hands that were glowing with confusing special effects, he tried to block Seekvaira's attack by dividing it until there was nothing left.
But would he be able to do it?
On the other side, Eiji laughed.
"The Divine Dividing ability is truly unique, but its weakness is obvious."
"What's the weakness, Eiji?" Asked Rias curiously.
Akeno, Koneko, Gasper and Yuuto also glanced at him and wanted to know what the weakness of Divine Dividing was.
"Continuous use of Divine Dividing's Divide ability will drain the user's stamina significantly. If the user has no way of releasing the excess power stored in their wings, they will be forced to bear the burden of carrying the excess power and this may temporarily stop Scale Mail."
"At that time, Vali will not be able to block Seekvaira's attacks and..."
Rias and the others were a little surprised, they looked back up at the sky and knew what would happen next.
*Boom!*
The power of Seekvaira's attack was like sea water that did not think of limits even though its power was not as strong as her previous attacks.
However, it was more than enough to blast Vali until his armor shattered into pieces.
The guy instantly fainted and was free-falling in the sky.
"Vali!"
This time it wasn't Albion who shouted his name, but Arthur and Bikou. They frantically rushed to where Vali was about to fall and prepared to catch him.
Vali-chan...
Rizevim looked at his grandson who couldn't even withstand a single attack from Seekvaira with disappointment.
What a useless grandson.
He cursed in his heart.
"Now, you can die, Rizevim."
Seekvaira aimed her Breath Gun at the man she was referring to and fired.
Except for her grandson, Vali. Rizevim had no plot armor like the protagonist and was completely dead.
His body turned into ashes.
"Next..."
Seekvaira prepared to annihilate the remaining Rizevim forces that seemed to be inside the Agreas Dome.
The inside of the massive structure could not be seen from the outside. But before she could do so—
"KRAAAAKKKHH!!!"
A high-pitched roar rang out and made many creatures in the four realms including Seekvaira shudder.
And it came from... Break!
The Agreas Dome shattered, many Evil Dragons and Evil Spirits came out like the scene where the final boss usually appeared.
It was not wrong, because at this moment, there was also another enormous creature that was raising its head.
Its appearance was extremely terrifying.
It was like a huge beast with characteristics derived from various animals such as lion, leopard, bear, dragon, etc. It has seven necks, seven heads, ten horns, and seven long, thick tails of various shapes. It also has four sturdy arms and two legs that are even thicker than its arms.
Its primate-like main body leans forward and is covered in black fur and what looks like scales all over its body. Its size was well over a few hundred meters, making it much larger than the Great Red.
Agreas was unable to hold its weight and almost fell if the creature did not fly away immediately.
Its shadow alone was enough to cover the entire Zhangjiajie City and other surrounding cities. Many ordinary people were naturally panicked and frightened at this moment.
However, there was one person who was elated.
[Finally this big guy appeared. Rizevim seemed to have used his own soul to destroy the seal made by the God of the Bible. His death left the legendary beast from Highschool DxD, 666 or also called Trihexa free from its seal.]
"!!!" The heroines of DxD were shocked.
As for those from other franchises?
They were just confused because they didn't know how terrifying the big guy Eiji was referring to was.
Eiji even sounded excited now.
Rias, Seekvaira, Akeno and the others trembled at the sight of the huge figure that covered the entire sky in their eyes.
"This..." Seekvaira suddenly felt guilty. If she hadn't killed Rizevim...
"Seekvaira, good job. You don't have to feel guilty because this is the punching bag— the opponent your fiancé wanted."
Eiji suddenly appeared beside her and said that.
Seekvaira's lips twitched, she clearly heard him call Trihexa a punching bag. But because of that, the guilt she felt and her fear immediately disappeared.
So it's okay as long as her fiancé is happy, right?
Many creatures in the supernatural world would be angry if they knew what Seekvaira was thinking.
How could that be okay?
Trihexa, a creature more terrifying than Great Red had now broken free from the seal created by the God of the Bible.
That means doomsday has arrived!
