[Chains of Heaven]!

A Divine Construct created by the gods to bind other gods, specifically designed to counter the—King of Heroes, Gilgamesh.

Its power to bind increased in proportion to the target's Divinity. However, against an ordinary human, it was nothing more than a sturdy chain.

One of its most notable feats was when Gilgamesh and Enkidu used the—[Chains of Heaven] to capture the—Bull of Heaven, the strongest of the Divine Beasts.

Enkidu also used it to halt the advance of Tiamat during the final battle in the Babylonia Singularity.

"The [Chains of Heaven] is a formidable weapon."

'When I fight in the future, I can just use this to restrain my enemies. Since this world is full of Gods and Devils, it'll be especially effective. How wonderful—!' I thought to myself, feeling quite pleased.

....

After spending some more time with the five girls, it was getting late. I noticed a marker on my—System Map.

"I have some business to take care of, so I'm heading home first. I'll come see you again when I have time."

"What is it? Do you need any help?"

The five girls had just officially become my girlfriends, and they were reluctant to part with me so soon.

I kissed each of them on the cheek and told them I had important matters to attend to.

They pouted, a little dejected, but ultimately waved me goodbye.

....

I left and ran to another nearby bridge, where I found—'her'. She was wearing her school uniform with black stockings, had a delicate, oval face, a straight nose, rosy lips, and fair skin.

It was none other than—Aika Kiryuu!

But I didn't have time to admire her beauty right now. Kiryuu's mental state seemed very unstable, as if she were about to jump into the river! I quickly rushed over to stop her!

Using my abilities—I peered into her mind and saw a dark shadow.

It was a black cat with a single vertical black line in its crimson eyes. It looked incredibly sinister.

I was startled. 'A black cat? What does this mean?'

Without overthinking it, I channeled my magic power into her, slowly suppressing the black cat in her mind, allowing her to regain consciousness.

Kiryuu slowly came to, and seeing my smiling face close to hers, holding her hand, she let out a small 'yelp' and quickly pulled her hand back, blushing.

"You're Hibari Kyoya? Wh-what are you doing? Where is this—?"

I didn't answer, instead waiting for Kiryuu to calm down before explaining what had just happened.

....

"Oh, I remember now. Thank you, Kyoya-kun."

"Have you experienced anything strange or unusual lately? Or had any strange dreams?"

Hearing my question, Kiryuu's expression changed. The reason she had wanted to jump into the river was still a fresh and scary memory.

Kiryuu remained silent for a full five minutes before finally speaking.

"Kyoya-kun, for the past few days, whenever I fall asleep, I have the same nightmare. I dream of a strange black cat chasing me. Several times, I was so scared that I fell into the water and almost drowned."

"A black cat."

I frowned. I had a hunch about what was going on.

....

I told her I was worried and insisted on walking her home.

"Huh? Kyoya-kun, we're not that close. Why are you being so nice to me? Are you sure you don't have ulterior motives?"

"And I know about your close relationships with Rias-senpai and Akeno-senpai. There are even rumors that Koneko-chan has fallen victim to your charms! But someone like me—"

"...."

"You underestimate yourself. If you dressed up a bit, you'd definitely be the center of attention." I looked at her, a strange smile on my face.

"Besides, wouldn't it be nice to have an—'Experienced Friend'?"

"To say something like that so calmly. Just what I'd expect from you, Kyoya-kun." Kiryuu rolled her eyes at me, then sighed.

As we walked along the street, I decided to take her to a place with a nice night view, hoping the romantic atmosphere would help dispel the shadows in her heart.

Kiryuu just looked at me, a strange expression on her face, and muttered, "Honestly, I already said I can go home by myself. You don't have to worry about me."

I didn't respond, my gaze fixed on something ahead!

She followed my gaze and felt her blood run cold.

A black cat, nearly two meters tall, slowly emerged from the darkness. Its fangs were bared, and its eyes glowed green.

Kiryuu turned pale, trembling as she stared at it. A deep sense of unease and terror welled up inside her. She stammered, "Th-this is the black cat from my dreams! Am I still dreaming?"

Seeing the look of despair on her face, the black cat seemed to grin even wider, its expression becoming even more scary as it slowly approached them.

But just then, I spoke, my voice surprisingly nonchalant. "Kiryuu, This 'thing' has been haunting your dreams and nearly drove you to suicide, hasn't it?"

Hearing my words, Kiryuu was stunned. 'So that's it. That's why Kyoya-kun insisted on taking me home.'

She felt a surge of guilt, realizing that she had put me in danger.

Forcing herself to calm down, Kiryuu decided she needed to buy me some time to escape. "Kyoya-kun, Run—I'll hold it off!"

But I simply pulled her behind me and said, "Just stay back and watch."

My eyes sharpened, crackling with blue energy. In that instant, I made my move.

A thick bolt of blue lightning ripped through the night sky, like divine punishment, striking the black cat directly, instantly turning it into a charred crisp.

It was dead beyond dead!

"Uh...!" Staring at this unbelievable scene, Kiryuu was dumbstruck, then she excitedly asked, "Was that black cat one of those monsters from manga? And Kyoya-kun, you must be an exorcist or an Onmyouji, right?!"

I just smiled at her reaction.

....

Then I explained to Kiryuu about the black cat, about this world, about the Three Factions, and about the various pantheons.

Only then did she finally understand that the black cat was a creature called a Stray Devil, and that there were many beings in this world that existed only in legends.

"Wow, so your lives are so exciting. I'm so envious!" Kiryuu exclaimed, stars in her eyes.

Seeing Kiryuu's envious expression, I continued to tempt her.

"So, Kiryuu, do you want to become a Devil? you'll have an eternal life and an exciting life like mine."

"Hmm, become a Devil? That sounds kind of nice!" Kiryuu thought about it for a moment.

"If you decide to become a Devil, I'll give you a lavish gift!" I continued to entice her.

"In that case, I've made up my mind! I want to become a Devil, too!" Kiryuu finally made her decision.

Seeing that she wanted to become a Devil, I took out the purified—[Vritra's Sacred Gears] that I had extracted from Saji.

Then I explained all the information about the [Vritra's Sacred Gears] to Kiryuu.

After hearing the explanation, Kiryuu was completely stunned.

She couldn't believe that the gift I had mentioned would be so valuable.

Before Kiryuu could react, I directly implanted the [Vritra's Sacred Gears] into her body.

Feeling the strange power within her, Kiryuu looked at me curiously. "Kyoya-kun, why are you so nice to me?"

"Hmm, didn't I already tell you? I'm interested in you, Kiryuu. Isn't it normal to be nice to your 'future' wife?" I said with a serious expression.

"Uh..." Hearing my sudden confession, Kiryuu blushed, not knowing what to say.

"Also, when you see Yura later, just tell her you want to meet Sona. She'll take you to her. But don't tell her that I gave you the [Vritra's Sacred Gears]—Just say that I recommended you because I think you have great potential." I thought for a moment and instructed her.

"Oh, and one more thing. Your friend Yura is my first girlfriend."

"What?! That Yura! How dare she find a boyfriend without telling me! Just wait till I get my hands on her!" Hearing my words, Kiryuu was furious.

"Alright, Kiryuu, it's getting late. You should head home. I'll be going now. Remember to go see Yura tomorrow." I said, preparing to leave.

Just then, Kiryuu grabbed me and kissed me on the lips. Then, before I could react, she blushed and ran off towards her home.

Seeing her dash off, I touched my lips and smiled.
