The Dimensional Gap is a gap that exists between the three worlds (Earth, Heaven, and Underworld) and is considered a void world whose environment features a mixture of shimmering colors.

In the original work, Eiji remembered that after Great Red was killed by Regalzeva, this place was occupied by Regalzeva and his army.

However, in this life it was different.

Great Red, or rather Irene had been saved by him and his women, and now she was still alive.

Speaking of her name.

In fact just a moment ago, Great Red said she had no other name. Ophis and other people often called her Great Red, True Dragon God, Dragon of the Apocalypse or other dragon-related nicknames.

Eiji was a little dissatisfied because it was a little awkward to call his future wife by such a name, especially in bed— cough, I mean keep calling Great Red in everyday life.

So he decided to give Great Red a name suitable for a beautiful and sexy woman like her.

He gave her a name similar to the mother of a heroine from Fairy Tail, Irene.

Only Irene, like Ophis did not have a last name.

However, it was only a matter of time before they added Seiya to each of their names.

Great Red did not object and was quite happy to be called Irene. Without her realizing it, in a short period of time, she and Eiji had become closer.

"Well, which one of them has injured you?" Eiji asked while glancing at Regalzeva and Han Xiao who seemed to be fighting before he came.

In the original work it was clear that such a thing did not happen.

After all, the two of them were from different franchises.

But since this was a crossover universe, such things could happen.

"Let me guess, it must be that black robot, right?"

He pointed at Regalzeva.

Hearing Eiji call him a black robot, Regalzeva was so angry that his body trembled and his eyeballs glowed.

He tried to move his body, but he was unable to do so which made him surprised.

Irene nodded, "Yes, it was a creature from another world that defeated me earlier."

"But..." She glanced at Han Xiao, "I don't know who the others are."

Eiji decided to reveal the identities of the two people.

"That black robot is the Evil God of Evie Etoulde, Regalzeva. And the other is a Chinese from another world, Han Xiao."

Regalzeva: How does he know where I'm from?

Han Xiao: Who are you calling a Chinese from another world?! That's not wrong, but the way you say it sounds mocking... Huh? How does he know who I am?! He... Does he also know I'm a person who has transmigrated?!

The former was curious and the latter panicked.

After all, what was the golden rule for the protagonists who transmigrated?

It was a secret that they had transmigrated and had knowledge of the future.

Han Xiao had never told anyone that he had transmigrated into the games he had played.

And with the help of his system, he was able to gain many opportunities along the way and make him grow strong at a terrifying rate.

It was now natural for Han Xiao to look at Eiji with a hint of fear in his eyes.

The other party seemed to know he was a transmigrated person.

Was he going to threaten him with that? Damn it!

What Han Xiao didn't know was that Eiji didn't take his transmigrator identity seriously. Currently, he smirked and wondered how he should deal with the protagonist of The Legendary Mechanic?

It was a bit boring if he just killed him without making him notice the two green hats on top of his head.

As for Regalzeva?

"The two of them have no good intentions of coming to this world. Eiji, let's kill them all."

Irene honestly didn't care about the identities of Regalzeva and Han Xiao.

As the guardian of the Dimensional Gap, she had to eliminate threats from otherworldly evil beings.

There was killing intent in Irene's eyes, but before she transformed back into her dragon form, she felt a hand placed on her shoulder.

"Let me do it. Irene, I'd rather see you in this form, you're so beautiful."

Eiji stopped the red-haired woman and teased her.

Irene blushed, "Alright. Eiji, I'll leave them to you."

Before this, she almost never used her humanoid form and was always in her dragon form.

So except for Ophis, she had never even interacted with others, especially men.

Even so, she was not stupid and had high emotional intelligence. After all, she was the God of Dreams, she learned many things through everyone's dreams including romance and even lewd things that men and women could do.

Eiji was obviously interested in her and was seducing her.

Irene didn't mind, she just felt a little embarrassed as it was the first time someone else had complimented her beauty.

[Dragon God, Great Red seems to be an easy woman.]

[Gosh, I can't wait to...]

The heroines: "....."

What can't you wait for, Eiji?

Let us guess, you definitely can't wait to have fun with Great Red in bed.

At the Occult Research Club.

Rias and Sona had gathered with their respective peerages.

They had received word from the alliance about something bad that might be happening in the Dimensional Gap.

One of the Devil Kings in the underworld, Sirzechs and the other Alliance leaders had agreed to ask Team DxD for help to investigate the matter.

Rias and Sona did not refuse.

But until now, they had not done anything because they knew Eiji was in the Dimensional Gap with Great Red/Irene.

According to the news they got from the women in Eiji's house, the two people were planning to deal with the Evil God from another world.

Knowing Eiji's power, Rias and Sona certainly felt calm and just needed to wait.

From his inner voice, Eiji could even still lust after Great Red. So he should be fine, right?

"Um... Kaichou, don't we have to do something? The Devil King, Sirzechs-sama has asked for our help, why don't we go to the Dimensional Gap?"

The question came from Saji.

As a male servant, he stood with Yuuto and Gasper on the other side of the room and could only watch Sona and Rias several other girls sitting and drinking tea.

Sona glanced at Saji indifferently, "Saji, that matter is being handled by Eiji. We just need to wait."

"But..." Saji actually wanted to show the results of his training in the past few months.

Although he had given up on pursuing Sona because he knew she had become Eiji's woman.

He was a young boy, it was natural for him to have the desire to show off to pretty girls, right?

"There is no but. Eiji is very strong and doesn't need us to deal with Regalzeva."

"Of course if he needs help, we are ready and can go to his location anytime."

Sona said firmly.

Saji's shoulders drooped, Yuuto held his shoulders as if comforting him.

Feeling that touch, Saji shuddered but before he brushed off Yuuto's hand, he felt sad and bitter as Rias suddenly reminded him of—

"Some of us including Sona are also carrying Eiji's child. If possible, we should not participate in the fight."

Just kidding.

With Chisato's blessing, those who were carrying Eiji's child didn't have to worry about that kind of thing.

However, Rias who had been heavily influenced by her fiancé could see through Saji's intention to show off and gave him a mental attack.

While she drank her tea with an amused smile.

Saji's face looked a little pale, he glanced at Sona's stomach which was still flat but slightly distended compared to a week ago.

He felt green and refrained from crying!

Eiji made him so envious!

In the past few months, he even often had nightmares about Eiji and Sona having sex. He couldn't see the scene clearly, but he could hear Sona's lewd moans and every time she called Eiji's name lovingly.

It was like torture for Saji!

[Sona: Rias, you're evil.]

[Rias: What's wrong, Sona? Don't tell me you want to defend Saji?]

[Sona: Don't say nonsense that can make Eiji misunderstand, Rias. I just think your personality is getting worse and worse.]

Sona glared at Rias coldly.

Rias wasn't afraid of her best friend's gaze.

Soon, they started arguing in the group chat.

"....." Akeno, Koneko and Tsubaki were silent.

Just like Eiji who was never satisfied adding members to his harem until it made them numb.

Rias and Sona's cat and dog fight also made them feel the same way.

Back again to the Dimensional Gap.

"Do you have any last words before you die? You can speak now."

Eiji said to the protagonist in front of him. However, he still restricted the movement of his body with Time Matter.

Han Xiao felt humiliated, but smiled falsely. "Bro, I think there's a misunderstanding here. I came to this galaxy just to look for something."

He was honest and hoped Eiji would let him go.

But, he did not expect the other party to suddenly bring out something he had been looking for all this time.

"Are you looking for this?" Eiji asked while holding the Evolution Cube in one of his hands.

With Rasiel, it wasn't hard for him to figure out what Han Xiao had come to Draconic Deus for.

Han Xiao's pupils shrank, "You... You have it?!"

He was again shocked and completely confused.

How could the Cosmic Treasure be in Eiji's hands?

"Yes, I have it. Do you want to snatch it from me?"

Han Xiao wanted to say yes, but he wasn't stupid enough and knew he couldn't beat the man in front of him.

The beautiful woman with red hair in the extremely voluptuous behind him also didn't seem to be weak.

He gritted his teeth and said, "Since the relic is in your hands, I give up on getting it. I just want you to let me go and after that I'll leave here."

Eiji rolled his eyes, unlike other Chinese protagonists who were extremely arrogant and would rather die than endure humiliation.

Han Xiao was a protagonist who was quite flexible and good at currying favor. But he was very vindictive and once he had enough power, he would definitely take revenge on his enemies.

"Letting you go is impossible. Don't worry, you won't die alone." Eiji said with a faint smile.

Han Xiao's face darkened, he looked at him with hatred in his eyes and stopped pretending. "No! You can't kill me! You seem to know who I am and we have no grudge against each other. I'm also a legendary mechanic! I-I can make you—"

Before he could finish his words, Eiji activated his Rinne Sharingan and released Amaterasu.

He himself possessed the skills of the Emperor Mechanic.

If he wanted, he could make a mechanical army that was no less than Han Xiao's toys.

Unfortunately, his power was more than enough to destroy his enemies.

"AHHHHH! HOT! WHAT KIND OF FIRE IS THIS?! EIJI, YOU BASTARD!!"

Han Xiao who was burned by the black flames roared and in less than 10 seconds, he turned into ashes.

However, Eiji immediately used his power as a Shinigami and stored the soul of the protagonist of The Legendary Mechanic into his inventory.

He had the idea to torture Han Xiao the same way he did Diehauser.

"That's a good fire." Irene praised him.

How could Eiji not be pleased?

He turned around and humbly said, "That's just one of my skills, Irene. If you want, I can also make you even stronger than you are now."

"Oh? Can I? I want to try it." Irene was suddenly interested.

If she became stronger, she could better protect the Dimensional Gap and prevent creatures like Regalzeva from threatening the world they lived in.

Eiji blinked his eyes, he didn't expect Irene would actually be interested in that topic.

He suddenly knew how he should woo a woman like Irene.

But looking at Regalzeva who was standing not far from them and had a very ugly looking expression.

He pretended to cough and said, "We'll talk about this after we return to my house."

"Okay, Eiji."

Soon, Eiji was standing before the final villain boss of Highschool DxD.

"You can also speak now, Regalzeva."

"Your name is Eiji? Let me go and fight to the death with me!"

After regaining the freedom to speak, Regalzeva didn't act cowardly like protagonist Han Xiao and directly challenged Eiji.

Eiji looked at the robot in front of him with a bored expression, "What if I refuse?"

Regalzeva snorted and the eyes on his forehead flickered like a red traffic light.

"I have contacted my troops and informed them about how interesting this world is. Now they must have accelerated their journey to get here and by then..."

Regalzeva laughed like a villain boss, "Hahaha! This world will be destroyed!"

"So it is." Eiji nodded.

"Do you understand what I'm saying, Eiji?"

"I understand."

"Then let go of me!"

Eiji held his chin before extending one of his hands into the void beside them.

Instantly, under Regalzeva and Irene's shocked gazes. A portal showing an army consisting of millions of mechanized humanoids appeared.

Compared to Han Xiao's mechanized army, although there were fewer of them, Regalzeva's army called the Devastator Order had a stronger and more terrifying combat power.

However, in Eiji's eyes, it was nothing more than a bunch of cannon fodder.

"Ji Noavus."

He uttered the name of one of Anos' spells. From the palm of his hand, an extremely complex ancient rune was created, a lightning bolt with three colors; blue, purple and black struck towards Regalzeva's army.

The size of the strike was so large that it was enough to swallow a planet. Regalzeva's troops could not dodge and after being hit by the lightning strike, their bodies were torn apart until their source was shattered into pieces.

They were all dead and there was no possibility for them to be resurrected in any way.

Eiji closed the portal and glanced back at Regalzeva indifferently, "You're talking about them? As you can see, they are all dead."

"....." Regalzeva.

"....." Irene.

The latter was amazed and looked at Eiji with a slight blush on her cheeks.

That's so cool, she thought.

As for Regalzeva? His body trembled, there was fear in every eye that clung to his body.

He ventured to ask, "Eiji, who are you really?"

"Me? I'm the Hegemony Demon God."

Eiji said while replacing his Rinne Sharingan with Magic Eyes of Mayhem. His pupils now had crosses and shone with a light purple color.

Stared at by those eyes, not only his body, Regalzeva felt his soul trembling with fear.

Even so, he was one of the strongest Evil Gods in Evie Etoulde.

He was so arrogant!

Knowing Eiji was so strong, he was even more excited and wanted to fight with him even more.

"That's it, I'm already tired of talking to you. You can die."

"Wait, Eiji—AAAHHHH!"

Another scream sounded in the Dimensional Gap.

In front of Eiji's Magic Eyes of Mayhem that could destroy even the indestructible, Regalzeva's body and source collapsed until his entire existence vanished.

However, as if feeling Eiji's gaze, the Dimensional Gap shook.

Eiji immediately made his eyes return to normal because if not, the place he was currently in would also collapse.

Irene swallowed.

She knew Eiji was powerful but wasn't he too powerful!

He killed an Evil God from another world with just his gaze!

"Irene, let's go back. I'll tell you how to become stronger."

Eiji shamelessly wrapped his arms around Irene's waist.

Irene gasped and her face felt hot, she knew she was being used by Eiji, but she was reluctant to refuse.

For example Tiamat, a female dragon like her easily fell in love with Eiji and was willing to become his woman after she was defeated by him.

Irene's case was more or less the same.

After seeing how strong Eiji was with her own eyes and even being saved by him.

It was hard for her not to fall in love with him.
