My wife's sisters want me to make a harem?!

Tuto and his comrades quickly left the elven forest. They went through the Demon Spider's forest next.

Nothing could stop them, even those dark and thick webs.

They appeared in barren land in less than ten minutes, then their bodies rushed toward a specific location.

In their hearts, a small rune conveyed the location of Overlord Enemies within Minato's world.

However, that small rune was actually part of something more significant.

It was a rune that hailed from higher worlds!

"This world's mana density is overwhelming... If we are too careless, we will get intoxicated and have our own mana turn into poison!" Yuro added.

That was a terrifying world already!

How could mana just slowly increase like that? That was an unprecedented ability that outclassed all Ovelords they have seen so far.

After all, mana was everything. Even if people practiced runes rather than mana circles, they still needed mana to utilize those physical runes! Strong physiques turned mana into their raw strength passively!

That ability was too strong and incomparable to other Overlords. For example, one of the Overlords Tuto had killed had the ability to bring out the Mana Sword from his whole world. That man turned his entire world's mana into one slash.

That was dodgeable and not as terrifying as the whole world progressing at an astounding pace!

Another Overlord could turn his dungeon races into raw cauldrons. That was also not on par with Minato's World's ability.

Cauldron had its limit, but Minato's limit was the races he conquered and his own limit! What was Minato's first race? The Elves!

The Royal Race from one of the highest worlds!

His own limits also seemed beyond boundaries!

Out of all Overlords, Minato was undoubtedly the biggest surprise and threat.

And that was not the end of the surprises.

"They should be here..." Tuto stood before the invisible castle.

His hand extended, and he gently touched the invisible wall. That wall lost its cover and became exposed to all six eyes in an instant.

The three comrades exchanged glances, then entered the stronghold.

Their eyes dilated on the spot, and their breath stopped for a few seconds.

"Guys?" Tuto asked after he'd woken up from his stupor.

Before him, a race he wasn't aware of was frozen in time.

Demonesses.

Women with unparalleled charm were scattered like ants throughout the whole castle. Their broad wings unfolded, and their long heart-shaped tails nearly forced Tuto to extend his hand to grasp them all.

Their milky skin didn't allow this silent and dark castle to eclipse their beauty, which suited Minato's tastes. 

Tall, voluptuous, and appealing.

That was for their beautiful curves.

Their clothes varied.

Some wore leather and tight clothes, which protected their enticing parts. Some were donned in heavy black armor that contrasted their skin. Some wore long robes which just exposed their faces and wings.

Those enticing women left the three comrades speechless.

"Let's awaken them... They should take care of the Overlord..." Yuro said slowly, barely able to hide his boner and desire.

Tuto and the third comrade didn't comment on his attitude. Should they part their lips, they would sound the same, which would betray their emotions.

At last, three of them utilized their runes...

To no avail!

"Huh?" They couldn't awaken those demonesses!

Their tries were rendered useless by those charming bodies. It was as if all of those demonesses were shrouded in a foreign aura that repelled their runes.

Tuto whispered, "This is a low world... This is newbie Overlord... How... How come we have met such a monster?"

Even Minato's Overlord Enemies were too unique!

Tuto would've shouted a few times already should the place be much different! Alas, he couldn't vent his feelings, and fear once again sprouted in his heart.

He was clueless...

He was so clueless!

None of them knew what to do and how to proceed should their rune fail. Their leaders from the upper worlds didn't even tell them about such a possibility.

"If we can't use his enemies, then we are done... He should've already called most of his forces to keep his Overlord Pillar safe... If we can't return, we will die of starvation or mana poison," Yuro said.

That was when the sound of footsteps rang out in the whole castle.

All six eyes rose to the peak.

Coming downstairs was a man clad in long black robes. He had blonde hair, and his eyes were hidden behind the sunglasses. He wore a cordial smile on his face despite foreign entities entering the castle.

He gently strutted on his sandals, then faced the three comrades, "Overlord Enemies... The reason you can't wake up those ladies is well... Because of me! Haha! They aren't really enemies, you know?

No one of you is His Majesty's enemy," he smiled.

"H-His Majesty?" Tuto stuttered.

"The fact that I see you all here means that Evelynn is on the hunt. Sadly, I can't let you all leave, for you've seen me... and him," A man with sunglasses whispered with a severe tone, then the whole castle shook.

A dark red miasma sprouted from behind the big gates!

"H-Hatred? Ravash? Ravash's hatred is here?" Yuro and his comrades took steps back as such a thing was never ever heard in the whole universe!

Well, not many knew about Ravash to begin with.

The blonde-haired man nodded, "The real enemy is him."

Those words angered the existence which has been exuding hatred. That beast roared behind the gates, then its howl finally opened those!

What came out was a giant dog over ten meters with three heads, "You dog! Enough of your games! I've finally broken the seal!"

The heads spat so much saliva the whole castle's room reeked of a disgusting smell. Their eyes locked on the blonde-haired man, who still wore a pleasant smile.

He didn't turn around but raised his eyes at the trio, "It's good that you can't leave this place. It saves me some conscience. Become food for Ravash's Heavenly Beast. Ah, you would like to know your killer.

This dog is known as Cerber. One of twelve heavenly beasts. Their title might be overbearing, but heaven was shared by four entities back then. It's pretty cringing for that guy to call his pets heavenly, don't you think so?" he jested.

"D-Don't kill us..." The trio beseeched.

Alas, the blonde-haired man shook his face, "This is the only way for me to seal him. I need to use you as fuel and his food. You also can't leave this place... No one who saw Ravash's beast can't."

He lifted his hand, then an unknown presence pulled Tuto straight to Cerber's jaw. The blonde-haired man did the same to Yuro with another sweep of his hand.

The third comrade stood frozen as he stared at his buddies dying within the jaws of the heavenly beast.

His eyes lowered, and he noticed the golden eyes shining at him, "W-What do you want? Just kill me already!"

"I have got a question. Have you seen the High Spirit around the Overlord or in his world?" The blonde-haired man asked, then pushed his sunglasses through his nose.

The third comrade remembered something, "The whole world was sealed by an unknown magic circle! So it was High Spirit in the end! No wonder! No wonder!"

That guy couldn't answer precisely, so the blonde-haired man just threw him to the last and desperately waiting Cerber's jaw.

He then sealed the beast and looked far to the north, "Her memories should still be sealed, so her power can not encompass the whole world... In this case, another High Spirit?"

A smile disappeared from the blonde-haired man's face...
