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

"I shall officially congratulate you on your first world's conquest, Minato," Bei stood with glasses and a written schedule in her hands.

Facing her beloved, she pushed those and smiled widely, then dropped all her staff. She congratulated him with a deep and enjoyable kiss.

Minato rolled his eyes, "That's official for you?"

"It is," Bei grasped Minato's hand, then guided him onto her wide ass.

After he squeezed her cheek enough, Bei let him go, and both of them headed straight to the world tree.

Their conversation continued with them holding their hands like lovers.

"I was thinking of going to another low world to sow more fear... But that would be pretty deficient... I would rather face myself in the medium world and let other races reunite with their races in medium worlds, increasing their strength and loyalty in this way.

I also don't lack strength and should do good in the medium world..." Minato nonchalantly voiced his thoughts.

What bothered him the most were the Overlord Enemies in his world. The blonde-haired man reassured him that they weren't his enemies, but no one knew the truth. No one knew what was exactly going on in the whole universe.

They all would face each other.

Minato didn't know whether they would be of a similar caliber as Cerber, but their strength should be top-notch since they were confined in his world. Besides, if someone with equal strength appeared in his world, Minato didn't know what he would do.

Perhaps, Heaven Sword's tip would help him, but Minato couldn't be sure.

Overlord Enemies scattered around the world shouldn't be a problem, however. Of course, people such as Snake Concubine were still a problem. Still, Minato believed he would be able to escape with his defenses, whether it would be the medium world's peak strength or someone with Snake Concubine's strength.

On his right, Bei nodded to his words, "Surviving became much easier for us."

Her tone lacked any jovial tunes as seriousness laced her voice. Remembering the Snake Concubine's dimension and how it sealed the high spirit's strength, Bei bit her lips and didn't comment further.

They appeared atop the world tree where two beauties and the cute spirit enjoyed the drinks.

Yuna smiled blindingly at her husband, "All ready, Minmin."

"We can go to the medium world!" Aya added.

Lastly, Leona nodded with her eyes on the cup.

Minato brightly smiled at them all and requested one teleport toward a random medium world. He wanted his second world to be a random one, which would be like tradition, even though Minato didn't believe he would randomly appear in the high world.

Once Leona passed him a well-written scroll, Minato side-glanced at Bei, who had avoided his eyes, then he unfolded it. A familiar yet more exquisite feeling wrapped him.

Minato glanced toward his beloved, "I will be going. Thanks, Leona, for your hard work."

"Have a safe trip. Call us when you are free," Yuna sent her husband with a dazzling smile.

The Husbando Overlord took a first step in the medium world, then!

"Medium World... It doesn't seem that much different from my world," Minato, donned in his casual clothes, looked around the forest he had appeared in.

He was perplexed after finding out that the mana of the medium world was much worse than his worlds. It wasn't precisely wrong, much better than the low world's air, but it fell short to his world's air.

After taking a few steps around, Minato confirmed that his world was much higher quality.

He was still surrounded by nature without any soul in sight.

Thus, he thought about Yuna and Bei's sister, "It didn't seem like she wanted to return anytime soon... If all she needs is mana, then her writing magic circles might evolve as my world increases mana of all beings within."

He didn't mind having such a unique and beautiful lady within his world. It was also good to build up a relationship with your in-laws, right?

Minato chuckled and continued his journey throughout the forest.

His first stop happened when he saw vulgar men chasing the young lady. She looked no younger than twenty years old, escaping with tattered clothes. She held those firmly around her chest, not letting anyone peek at her skin.

Her eyes expanded after she spotted Minato, "My beloved! They are here to stop our marriage!"

"Sorry, but I don't know you," Minato refused to play along.

He didn't like how the lady used him immediately and even spoke about such a precious thing as marriage.

Her eyes trembled after Minato's prompt refusal, and she dropped onto her knees, seemingly strengthless.

Tears flooded her beautiful hues, tumbling down on her pale cheeks.

Vulgar men caught up, standing behind her with grins. They licked their lips and extended their hands toward the fallen lady.

That was when Minato sighed, "I don't like being used by others, in such a way no less. But I also won't put a blind eye to such immoral schemes."

He lifted his hand and summoned his magic circles.

Those magic circles floated around Minato like written symbols, rendering the vulgar men speechless. They never saw such magic circles, yet they knew that those were undoubtedly magic circles for some reason.

Once Minato trapped them in box walls, he activated [Kill] and [Transfer], filling his body with rich life force. It was a life force from the medium world, much more abundant in resources than the low world people.

At the same time, the fallen lady turned around. She stared at the terrifying ability that sucked the vitality and all mana.

Her big eyes reflected the tremendous change as the vulgar men turned from youthful to elderly people in less than a minute.

She recoiled a few steps back, trembling no end.

Minato saw her movement and jested, "So you got your strength back?"

"W-Who are you? That ability must come from Mount Tagram, right?! You must be Reverend!" The lady spoke with reverence, lifting her body, then bowing before Minato with utmost reverence, "Forgive this young one's ignorance!"

Minato didn't shift his eyes to the lady.

Instead, he stared ahead as if trying to see through the whole world. He stood with his back straight, hands joined behind, and a profound gaze.

Deep inside, Minato was thinking, 'From the husband to Reverend... Still, Reverend and Mount Tagram sound like good places to start making connections here. If she mistook my ability for one of theirs, then it's worth investigating this mountain.'

Minato sighed, "This is where my journey ends... I have had enough of people's ignorance..."

The lady shriveled with genuine fear, "R-Reverend..."

"Lead the way to my home... If you manage to bring me here unscathed, I will forgive you your insolence," Minato whispered with a stoic face.

His new companion didn't see through his play, and her beautiful chest dropped as she bowed, "Yes! I won't let anyone reach close to you, Reverend!"

And that was the start of Minato's journey in the new world.

There were a few complications, however.

Mount Tagram was quite far away!

The other significant one was that this mount was a peculiar place....
