As the Demon King, I have married a slave elf. How should I express my love?

"Huh...? Wait, are we flying?"

A magic circle floated beneath Nefi's feet.

It looked like intangible light, but stepping on it still gave a feeling of being unsteady on the ground. If something like a flying magic carpet really existed, sitting on it would probably feel exactly the same.

Although it was difficult to move freely, Neferpitou still managed to create a foothold for herself using this clumsy magic.

The mermaid girl carefully lowered her feet... or rather, her tail, and followed behind Neferpitou.

Then, the two watched as Sagan and the others were busy fighting.

Of course, the most powerful of them all was Sagan's fist.

Although that punch managed to blast off one of the Mud Demon's arms, it immediately regenerated to its original state. Even with Raphael, Shessty, and the other magicians attacking together, they still couldn't land a decisive blow.

Perhaps exhausting the magic of the "Mud Demon" would stop it, but Nephtros would probably not survive by then.

The mermaid girl watched, holding her breath.

"Eh...aren't those people fighting for us? Can they win?"

"...Yes, Mr. Sagan will definitely be fine."

The problem is, what help can Neferpitou offer now?

The restless mermaid girl then cried out.

"Go, go, Mr. Demon King! Ah, should I sing it instead? Go, go, go, Great Demon King!"

"—It's so noisy!"

Sagan's roar echoed back, causing the mermaid girl to slump her shoulders in dejection.

"That's so mean! I just wanted to cheer him on..."

"The problem might be that you sang it as a song...?"

"But I'm a singer, and I can't do anything else besides singing."

"Sing……"

These words seemed to spark some inspiration in Neferpitou.

—The elven girl's song carried an unusual power.

Divine magic—ancient power personally recreated by Bifron, the Demon King.

If what the Demon King said is true, then Neferpitou should also be able to use it.

But what should I do?

If it could be used simply by reciting the song, Nephroth wouldn't have collapsed, and Biffron wouldn't have had to spend hundreds of years researching it.

The mermaid girl looked up at Neferpitou with trepidation.

"Excuse me... did I say something wrong?"

"No... I was just thinking about how to sing a song properly."

Even if you asked Neferpitou how to use magic, she probably wouldn't be able to answer.

But Nefi's casual mutterings made the mermaid girl smile.

"Oh, so that's what you meant. It's actually quite simple."

"Huh...?"

"While there are many techniques to singing, the most important thing is your own heart. Whether it's for your own needs, your own wishes, or for someone else, as long as you sing with your heart, your voice will definitely reach the audience. You could even say that if you don't put your heart into it, no matter how good your voice is, you'll always just be a second-rate singer."

As she spoke, the mermaid girl grasped Nefi's hand.　

"Even though I made someone angry just now, please cheer them on with me this time! Go, go, go, Great Demon King!"

The girl probably didn't think too much when she said those words.

But to Neferi, it sounded like the answer she was looking for.

Sing with your heart...

Just now, she made eye contact with Nephtros, who was falling after exhausting her strength.

Those eyes looked so sad, so resentful.

Most importantly, it looks like they're asking for help.

—Just like the Mr. Sagan I saw when we first met…

Perhaps, just like Neferpitou himself.

That's why Neferi couldn't let her do as she pleased.

Neferi wanted to help her.

I hope she can be saved.

As soon as a wish arises in one's heart, words naturally flow from one's mouth.　

"—He is the one who shines like a star. He holds the scales of justice, mediating between good and evil—"

Against the backdrop of moonlight, Neferpitou's body was gradually enveloped in stardust.

◇

"Tsk, still can't break it!"

Raphael brandished his holy sword and roared.

The flames of purification were not inexhaustible. As the intensity of the flames waned, the 'mud' began to retaliate against the group.

Of them, Shessty, who was not a magician and fought with her bare hands, expended the most energy.

"Sester, step back! Stop hitting her!"

"If I step down now, who will protect your back?"

Despite her fearless shouts, Shessty's foot slipped.

She has been fighting on the shipwreck as her foothold until now, but the shipwreck beneath her feet has been eroded by mud at some point.

"Tadpole head!"

Seeing this, Fa'er took her into the sky, but the "mud" stretched out like tentacles and attacked.

"Fair!"

But at that moment...　

"—He is the one who shines like a star. He holds the scales of justice, mediating between good and evil—"

Stardust falling from the sky pierced through the tentacles of 'mud'.

—Divine magic?

That was the magic Nephtros used.

But she had already been swallowed up by the mud.

So now, those who sing—

"It's Nefertari."

Against the backdrop of the moon, a pure white-clad girl sings a song.

It was a clear, melodious song.

Upon hearing that sound and color, Sagan finally had a sudden realization.

—I see. It seems Nefertiros and Nefertiros are indeed very similar.

That doesn't refer to appearance or looks.

Their pure voices, seemingly reaching straight to the heart, sang similar melodies like sisters.

The starlight generated by Nefi gradually tore apart the 'Mud-like Demon God'.

—The cards are all in hand.

Now we finally have a good chance of success.

"Sester, Raphael, clear a path for me!"

Sagan shouted and leaped out, and the "Mud Demon" stretched out his arms, intending to crush him.

"Shine—the Holy Sword Azrael!"

"Respond—the Holy Sword Metatron!"

Two paladin commanders rushed in from the left and right sides, shattering the arms of the "Mud-like Demon God".

But the 'Mud Demon' wasn't finished yet, and opened its mouth to roar.

"—This trick is no longer effective."

"Hee-hee-hee! Perish, <Barol's Eye>."

Far exhaled dragon breath, and Gomel cooperated by using his Demon Eye.

The head of the "Mud Demon" was shattered, and the dark elf girl trapped inside then slightly revealed her face.

But the regeneration speed of 'mud' is just too fast.

Sagan created a foothold with a magic circle and soared into the sky, but before it was within reach of a punch, it had already regenerated.

"—Get on!"

Just then, Sagan felt a furry touch brush against his feet.

"Simonli?"

"Ready to charge!"

The black lion sped away like a whirlwind.

—So that's how it is. No wonder it's called "Black Blade".

He moved with unstoppable speed, darting and raging like a flying arrow. His unstoppable figure resembled a black blade.

Now that the scales of heaven are shattered and order is lost, the earth will be stained crimson. Its lamentations will rise and it will soar into the sky—
