Hades was frightened, Eiji came to his door!

Unlike the underworld, which has an artificial sun created by Ajuka Beelzebub, the sky of the underworld has day and night.

The lowest layer of the underworld, the Realm of the Dead doesn't have one at all.

The sky there was a dark purple color.

The artificial sun created by Ajuka was unable to illuminate the region ruled by the God of Death Hades.

Inside a castle that looked very gloomy with many green flames shining inside.

Even though on the lit ritual altar there were artificial devils that had been mass-produced so that the number increased by 20 every 3 minutes, Hades who had recently been shocked by Eiji's aura several times could not calm down.

Even with the Book of Lucifer in his hand and Lilith's lump of flesh that made him capable of creating a troop of artificial devils in preparation for war with the Five Faction Alliance....

He was not calm at all!

"Why am I feeling more and more uneasy? It can't be!" Hades wondered in confusion and suddenly shouted in panic.

For some reason, since five minutes ago. Every second that passed, he felt like a person who was getting closer to death, he was sensitive to this feeling because he was the God of Death.

"Hades, what's wrong with you?" Asked Zeus who happened to be there and watched the troop production process that his older brother was doing.

He looked at the skull in royal robes strangely.

"Zeus, where are all the members of the Hell Alliance? Have they all gathered at my castle?" Instead of answering Zeus' question, Hades asked back.

Before answering, Zeus sighed. His wrinkled face seemed to recall the terrible things that happened not long ago before saying, "Those remaining after the death of Angra Mainyu, Erebus, Thanatos, Hypnos, and Oneiroi... and Nyx who's status is unknown. Our core members are not many, especially after Poseidon also died at that boy's hands."

"Everything is here."

When mentioning that boy, Eiji. Zeus had a dark and hateful expression.

Not only his other older brother, Poseidon. Angra Mainyu and Erebus also died at Eiji's hands.

What about Thanatos, Hypnos, and Oneiroi? They only knew their signs of life disappeared or died after they wanted to bring back Nyx who was suspected of being a prisoner in Eiji's house because of her beauty.

It had been a day since then. In the end they concluded that the three people also died at Eiji's hands.

They didn't know the three died at the hands of Serafall who was testing her new magical girl dress.

How could Zeus and Hades know these details?

They could only blame Eiji again because Serafall was also rumored to be one of his women!

At this point, the core members of the Hell Alliance were actually not many. There was only Hades, Zeus who joined because of his hatred for Eiji that was building up in his heart, crazy Devils like Rizevim, and Tartarus.

The rest that fell into the strong subordinate category were two super devils, one top-class grim reaper and more than a hundred thousand artificial devils. The latter number is still being increased by Hades with the help of the Book of Lucifer and Lilith's body.

Speaking of Lucifer's wife, when he first found out his older brother kept her body, Zeus was surprised of course.

However, it was a pity that the woman was not as beautiful as before because now she was a lump of flesh that even Zeus who liked to have sex with women of various races could not bear to look at her for too long.

"Then tell our troops to increase security and you should also stand guard outside the castle."

"Why all of a sudden? Wouldn't that attract attention too easily? The people from the Alliance might..."

"Zeus, just do it. Didn't you hear what I said earlier? I'm feeling more and more uneasy."

Why are you acting like a paranoid woman with that skull body, Hades? Zeus wanted to say this with a hint of disgust in his heart, but Hades' voice sounded serious.

He was reluctant to be ordered around by someone, even by his older brother, after all he was the King of Olympus.

But in this situation...

**Boom!**

"What's going on?! Someone broke down your castle door, Hades?"

"...."

Zeus glanced at Hades, he saw the skull trembling.

Zeus also knew how serious this matter was, especially when he felt the familiar aura that had not long ago enveloped the entire world.

Although now the fluctuations were smaller because the person wasn't exerting all his power, he knew it was the same person.

And it turned out that that person was...

"This castle is so ugly."

On the other side. After Eiji parked the car some distance away from the castle and he destroyed the fifty-meter-high castle door that was very thick and definitely reinforced by magic with just one casual slash from Judecca.

Looking at the castle grounds filled with black humanoids that seemed to be artificial devils in the original work, he greeted everyone with a smile on his face.

"Hello are Hades and the others inside? I came to visit."

Those hundreds of thousands of artificial devils had no intelligence of their own, they could only take orders from people like Hades and other members of the Hell Alliance.

And right now, their red eyes filled with killing intent were fixed on Eiji.

Countless demonic powers illuminated the castle grounds and all the artificial devils began to rush at Eiji.

There was an order in their brains just given by their leader.

Kill the intruder.

They charged at Eiji with sharp claws and various types of magic were cast from a distance.

Eiji didn't panic, he continued to walk forward casually as if he was walking in a park. With Judecca in his right hand, he performed several slashes that were coated by Judecca's magic and a bit of his own magic.

The result was that several hundred meter long dark and golden slashes were released. It was a Multi-Cast that cut through every artificial devil within range as easily as cutting tofu.

The castle grounds were filled with screams and the multiple magic slashes that Eiji had just released continued to advance relentlessly until it cut through the castle walls or anything in its way.

"Master, behind you."

"I know."

Judecca didn't seem to know how great the current owner was, how could Eiji not know someone with super devil power was hiding his presence behind him trying to stab him with his hand?

Without looking back and making a few more slashes forward, his left arm moved so fast that it did not leave any shadow to grab the opponent's wrist which made the other party surprised of course.

"!!!"

"Yo, Big Baby. Have you ever been a cannonball? You definitely haven't, I'll let you feel it." Eiji peered at the familiar face of the male super devil who even made Hades who was included in the 10 Strongest Beings in the world scared in the original work.

Before Balberith spoke, Eiji threw his body at the thousands of artificial devil troops in front of him. The super devil's body and Eiji's own physical strength made Balberith's adult male body that despite being only one month old fly at a speed that surpassed the speed of sound.

Not knowing how fast it was, Eiji wasn't sure but it was enough to slaughter thousands of artificial devils that were hit by Balberith's body that was torn and bleeding air because he couldn't bear that speed, even with his super devil body.

In the end the super devil was thrown hundreds of kilometers through the castle walls and barren mountains.

"Balberith!" Another Super Devil that Hades created using the Book of Lucifer and Lilith's flesh, Verrine looked at her brutally thrown brother in horror.

She then turned her gaze on Eiji with anger on her face. A super demonic power that was almost equivalent to the Four Maou except for Serafall who had been enhanced by the Master-Servant contract exploded from her body.

Flying in the sky, she created a giant fireball from the magic circle in one of her hands and threw it at Eiji.

"By order of Hades-sama. Eiji Seiya, you must die!"

Eiji stared at the fireball that looked like a small purple sun that Verrine created with her super devil power.

[That much size and power was enough to blow up Lucifad. Still, is this super devil, Verrine created by Hades not worried about killing her own master's troops with me? Oh what was I thinking...]

[After all, an attack of this level wouldn't even be able to damage my clothes. I've given Hades plenty of time to create his troops, but he's only created more than a hundred thousand artificial devils whose actual power is nothing more than low and mid class cannon fodder.]

[What kind of trash, I thought Hades could make a stronger troops than his original work, but he's so disappointing.]

The heroines...

Many of them thought the man was flirting with a beautiful woman somewhere but he turned out to be dealing with the God of Death, Hades?!

And there's still a hundred thousand troops?

Still, you're very disappointed with that many numbers and power which is actually more than enough to conquer a country or two in less than a day.

What shall we say? It is not Hades or his troops that are too weak but you Eiji, you are too strong!

Who can defeat you in this world? The protagonists even gave up long ago...

Not knowing what the heroines out there were thinking, Eiji supplied more magic into Judecca's jagged blade which was now lit up with some magic symbols.

He grinned and slashed at the giant fireball that was less than twenty meters away from him.

L'Ciel Cocytus.

This was one of the techniques Judecca possessed.

A dark slash containing anti-magic was released!

The slash was also supported by Eiji's physical strength increasing his speed, so it wasn't just the giant fireball that disappeared after being cut...

The air and space within the slash line were also cut off which even slightly surprised Judecca.

"My magic attack was cut off?" Verrine said in surprise, she wanted to attack again but he realized too late that half of her body had a slash.

She thought the dark slash that Eiji released had only cut through her giant fireball and dispelled it afterwards, but it had also cut through her body!

By the time she realized it, her vision had already gone dark.

In midair, Verrine's body split into two and because of the anti-magic content in Eiji's slash, her body that possessed abundant super devil power also perished.

It turned into black particles that were blown away by the wind.

"I feel like I'm the protagonist Asta of Black Clover."

[If you want to be him, you have to have a five-leaf clover Grimoir with anti-magic demons inside, host.]

"Then give me one."

[...You already have Judecca so it's not necessary.]

Just say you're stingy!

Eiji rolled his eyes, unintentionally he released more magic in his slash that instantly killed 90% of Hades' artificial devil troops.

The castle grounds that had been filled with a sea of artificial devils now had more space.

"Ah shit, I finished it faster... It's your fault, Miss System."

[.....]

I bet if Hades and his friends knew you could actually kill them all with one move in two or three seconds...

They would be so desperate that they wouldn't be able to stop themselves from vomiting blood on the spot.

Instead of fighting, they would choose suicide.

Miss System complained, but she did not say so and continued watching her host with a packet of potato chips.

What about Leme? Because she felt a little sorry for the loli. Miss System generously threw some food and drinks into the next room in the host's mindscape.

"Hm?" Leme, who was busy watching her king, was stunned to see a small pile of food and drinks that suddenly appeared beside her.

This must be from his next-door neighbor. Unlike her, the other party could access her room at will.

"Thank you Miss Neighbor!"

Leme said before opening a box of pizza and taking a slice to eat.

Eiji didn't know the interaction of two golden fingers inside his head,

"EIJI! Accept divine punishment!"

At this moment, a familiar old man's angry voice rang out from the sky that was suddenly filled with lightning that contained divine power.

Who else if not Zeus?

A huge pillar of lightning descended from the sky above Eiji's head.

**BOOM!!**

The vast area of the castle was blown up and hollowed out by Zeus' full-level attack.

Zeus was breathing heavily, actually while Eiji was busy slaughtering the troops of artificial devils and the two super devils created by Hades, he was secretly gathering his divine power to unleash his strongest attack.

Now underneath was a hole ten kilometers wide and deep... Zeus himself didn't know, but he burst out laughing.

"Hahahaha! Dead! Finally dead! Poseidon, I've taken revenge on that evil boy for you!"

"Hahaha! Hades, did you see that? At least your artificial devil troops weren't destroyed in vain! Hahaha!"

Zeus looked very happy.

If Eiji's women were there, some of them would go crazy and kill the old man brutally.

But Zeus was somewhat lucky because Eiji came to the Realm of the Dead himself.

However, when Zeus was celebrating his victory. He suddenly stopped laughing and widened his eyes, he glanced at the sky whose color suddenly turned pale white.

Not only the sky, but even Hades' castle and the surrounding scenery also changed color.

Whoever was there would see the world turn into a monochrome display as if the sky was white paper and objects were colored by the same color as a pencil.

Zeus' heart was pounding, sweat dripping down his forehead because he had a bad feeling!

Could it be...

"Your scared face looks cute Zeus."

"!!!"

Zeus who heard the voice immediately glanced at the other side of the castle wall in panic.

Standing on top of the wall in neat clothes without the slightest dirt and a sword shining with monochrome light... Unmistakably, it was him.

"Eiji! You, how are you still alive?! There's no way, even if you're not dead, there's no way you can survive my divine lightning without any injuries!!"

Zeus' expression looked very ugly. Besides being angry, he also looked very humiliated because that was divine lightning that was released with its full power.

But that evil boy. Eiji was still able to survive the attack without the slightest injury!

His clothes weren't even damaged at all!

"The proof is in front of your eyes and it will take more time to explain how great I am. I have to pick up my daughter at her school soon..." Eiji pointed the tip of Judecca at Zeus who was flying in the sky with an indifferent expression on his face.

"Vanish."

"What did you say?! Eiji-" Zeus roared and actually wanted to beg to let go because he had exhausted his divine power.

But hearing Eiji say something like picking up his daughter at school was more important to give him an explanation that wouldn't even take more than half a minute.

He was angry but he didn't finish his words because in the absence of the attack released from the tip of Eiji's sword at him...

It was as if erased by an eraser.

His body suddenly became transparent until it merged with the color of the sky which was now like white paper.

Although there was no pain, for the first time in his life, Zeus felt very afraid of someone's power and shouted for help to his older brother, Hades!

Hades! Hades! Save me!

But, alas. Just like his body, his voice also vanished.

Zeus died without knowing what exactly happened to him and a few seconds later after his death the colors of the sky and the surroundings... or rather the colors in the entire Realm of the Dead returned to normal.

What exactly was that? It was the Breakdown Phenomenon.

In the Trinity Seven franchise. This is a phenomenon where one's powerful magic gets out of control on a large scale. Normally this would cause massive destruction, people within the range of the magic would be disintegrated or disappear with supernatural effects.

A person's Breakdown phenomenon is different.

The original protagonist's Breakdown phenomenon is a black sun that sucks everyone in the city into it with a very strong gravitational pull as if it were a black hole.

Whereas Eiji's Breakdown Phenomenon? Unlike the protagonist of the original work or anyone else, he did not lose control of his magic, or rather he deliberately lost control of his magic by 2.5% which was enough to envelop the entire Realm of the Dead.

After accessing Judecca's magic, he had the understanding to create his own Breakdown Phenomenon which was the Monochrome World. If he wanted, he could erase the entire Realm of the Dead as if erasing it with an eraser.

But no, Eiji only targeted Zeus who was unable to escape the effects of his Breakdown Phenomenon.

After Zeus died and the rest of the artificial devil troops were slaughtered by him.

Eiji's footsteps echoed inside Hades' castle and he walked towards a certain room where he felt the throbbing fluctuations of demonic power.

Judecca's hook jingled with every step he took and he finally entered a room that resembled a ritual room.

"You finally came Eiji."

"Oh Hades, unlike your younger brother, Zeus... You look calm. Zeus just died at my hands and you can still sit here."

Eiji glanced at the skull in robes sitting on the throne with amusement. In the corner of his eye, he saw the lump of flesh that was the source of the demonic power he felt.

He mentally sighed as he only remembered her now.

"That's too bad, but just like Poseidon, Zeus also died because he was weaker than you, Eiji. I'm a little sad for my brothers, but that's it."

"We, the Hell Alliance admit defeat. I won't bother to stir up any more trouble with the Five Faction Alliance and you, Eiji in the future. So..."

Hades whose eyes were like torches said indifferently.

But Eiji could see the bones shaking. The God of Death seemed to be pretending to be calm to hide his fear.

"So?" Eiji asked boredly and then he remembered something and changed his question. "By the way where is Rizevim?"

"Rizevim? That bastard ran away without telling anyone."

When mentioning Rizevim, Hades' voice sounded like someone angry and betrayed by his girlfriend.

Rizevim had indeed helped a lot to strengthen his artificial devil troops. From the beginning, Hades only wanted him to be a scientist in his group and did not intend to put him at the forefront because he knew the man loved his life more than anyone else before achieving his goal.

Hades actually wasn't surprised Rizevim ran away when Eiji first made a scene at the entrance of his castle. He was just a little sorry and angry for having a pig as a teammate who had no loyalty at all.

However, Hades could also slightly understand why Rizevim fled early because he knew they didn't have the slightest chance of winning against Eiji.

After knowing Eiji's aura was familiar to the one who released his aura to cover the entire world and feeling his power more closely from the battle earlier that killed all of his artificial devil troops including his two super devils.

Especially the strange phenomenon that made the entire Realm of the Dead change color to monochrome and Zeus died because of it.

Hades himself was not confident in defeating Eiji.

If possible, he wanted to make peace with that boy and if it didn't work out...

"Okay he's lucky. So what did you want to say just now? Say it quickly." Eiji of course could kill Hades directly without much nonsense.

But his King Harem senses twitching, he decided to give the skull five minutes to speak.

As for Rizevim? Well, he could just look for him after this and would definitely find him. But it took time for that and picking up Kunou from her school was more important than chasing after the old man.

Besides, Eiji was sure that sooner or later Rizevim would appear in front of him and that would be the end of him.
