I Became the Husband of a Sword Demon

The stern yet apologetic woman before me was quite impressive. Unlike the otherworldly being I had encountered earlier, whose intentions behind their actions were impossible to discern, this woman, despite appearing human, exuded an aura that was far from ordinary.

“Regardless of the reason, it’s true that the creature’s attempt to disrupt the laws of your world originated from our failure. So, I must apologize to you.”

To casually discard such dignity and bow her head lightly to me… It made me reconsider my initial impression of her as somewhat frivolous. She seemed to genuinely feel responsible for the situation, which raised my opinion of her.

“If I could, I’d not only apologize but also personally remove the creature from its body and take it away immediately.”

Just the declaration of her willingness to actively address the situation indicated that she was determined to resolve the chaos caused by that otherworldly being, even if it meant doing so without directly intervening. However,

“…Unfortunately, a being of my stature cannot casually exert power in the material world. Even if I were to use my power sparingly, the consequences could jeopardize the very existence of the world. Therefore, it’s impossible.”

As expected, the woman explained why she couldn’t recklessly use physical force in my world, expressing her regret.

From the moment she effortlessly brought me into this strange space, disconnected from the normal flow of time, it was clear that she was vastly superior to the otherworldly being I had faced. If she had wanted to, she could have dealt with the creature herself without needing to summon me, thus avoiding any need to involve me in this.

I pushed aside my initial disappointment and listened intently to what she had to say.

Even though she didn’t make eye contact, she seemed to read my thoughts, acknowledging my attitude before slightly retracting her apology.

“It’s unreasonable because evil entities can wreak havoc without restraint, while we, who should stop them, are bound by the rules we created to maintain balance across many worlds.”

She voiced her dissatisfaction with the current situation, emphasizing how the beings trying to prevent chaos were constrained by intricate laws, making their efforts seem futile compared to the ease with which evil entities caused destruction.

But then,

“However, I did not call you here without any plan.”

With a simple flick of her thumb and index finger, she revealed a thick book that seemed ancient, its cover suggesting a treasure trove of knowledge.

I had imagined that reading such a thick book might grant me the strength to transcend the despair of reality, but…

“…A book?”

It was a thick volume, seemingly too heavy to hold. Despite the fact that we were in a timeless space, the mere sight of it made me wonder how long it would take to read it all. Yet, when she noticed my hesitation,

“Haha, it seems you don’t enjoy reading much.”

Her playful smile made me feel exposed, as if my thoughts had been read aloud.

“Though it may seem suspicious, trust me and simply place your right hand on the book.”

Her serious tone convinced me to comply, despite my reservations about the book’s thickness. The intense power emanating from it felt genuine, compelling me to place my hand on its cover.

Immediately, vast knowledge beyond human comprehension flowed into my mind, and with it, a surge of unknown power within me.

“Ah…”

The woman, seeing the flow of power into me, looked at me with admiration. Even though I had merely followed her request, her reaction suggested that I had surpassed her expectations.

“I didn’t expect such compatibility… This level of suitability was unforeseen.”

Her words confirmed my realization that the knowledge and power I received would be instrumental in confronting the otherworldly being disrupting the world.

Focusing on the delicate dance of power coursing through my body, I prepared myself for returning to reality and dealing with the situation there.

How much time had passed? When I no longer sensed the influx of knowledge and power from the book, the woman said,

“Hmm, it ended faster than I thought. You can let go now.”

She released me from the task, and as I slowly removed my hand from the book, I began to examine my body. The sense of fulfillment and the newfound difference in my perception of my own body were striking.

Only then did I understand why the otherworldly being had spent so much time observing the body it inhabited through Dominus’s form. It was instinctual to verify the condition of a body not one’s own.

With my new awareness, I felt confident about confronting the chaotic being hiding within Dominus’s body.

I was about to ask the woman to return me to my original world when she said,

“Before you go, let’s make a promise.”

“Of course. What kind of promise?”

Even though her request seemed vague, I was willing to listen. With a low voice, she spoke her conditions.

“Haha!”

After hearing her terms, I laughed heartily and replied,

“I understand. No matter what happens, I won’t break this promise.”

She assured me that breaking the promise wouldn’t result in any harm to me, but still insisted on the importance of keeping it.

“Human nature is to struggle to reclaim what has been lost, but I’ve seen countless times how it causes others to suffer.”

“…Agreed.”

I reaffirmed my commitment to her, and she relaxed, flicking her thumb and index finger again.

The thick book that had granted me immense power vanished as if it had never existed. Behind me, a light shimmered like an exit.

“Go and show them the true power. Show that arrogant creature who relies solely on its limited strength what real power is.”

With renewed determination, I walked toward the light, and before I fully realized it,

“I’m back.”

My consciousness returned to the reality where I belonged, and I saw the scene frozen, with the sword poised just before it struck Asulin.
