Muzan: My daughter can't be that weak!

Muzan's gaze followed the direction of Yukina's finger and landed on the rattan swing.

In his eyes, it was nothing more than a thing suspended in mid-air by two simple ropes, serving no purpose other than swinging back and forth meaninglessly.

And it will most likely produce annoying creaking noises and be a stupid wooden structure that is fragile and could fall apart at any time.

Does she think I look like I would have any interest in this kind of thing?

The idea struck him as utterly absurd.

Did he go swing on the swing?

Just imagining the scene was enough to make his brow furrow even more.

"I'm not playing."

He uttered two cold words, his gaze returning to the small pendant still hanging on his leg, his tone becoming more forceful: "Let go."

Oh, Dad is so cold.

Yukina swung Muzan's leg, facing the courtyard above, and let out a long sigh.

It was as if they had lost all their strength and means.

"Ah, the world is so unfair!"

She paused, stole a glance at Muzan, and added in an even more resentful tone, "Dad... how cunning!"

Muzan: "...?"

His attempt to forcefully pull away paused for a moment because of the sudden accusation.

Cunning? What new idiom is this?

What nonsense is she spouting now?

Feel……

This sounds familiar.

But he couldn't immediately recall where he had heard a similar sentence structure before.

Seeing that he didn't react, Xue Nai thought he didn't understand, so she turned her little face back angrily, looked up at him, her eyes full of accusation that "you know perfectly well", and her little mouth was so pouty that it could hang an oil bottle.

"Didn't Dad tell Xue Nai before that when something happens, you can't blame yourself?"

She repeated, word by word, "You can blame others for not being strong enough, blame the enemy for being too cunning, or blame the world for being unfair. That's what you said, Dad!"

"So! Now that Dad doesn't want to play on the swing, it's definitely not Yukina's fault."

"That's just because the world is unfair, and because you, Dad, are too cunning!"

Muzan listened silently to her complete and logically rigorous reasoning.

So that's where it's used.

He remembered.

They learn quickly.

However, the direction in which he used it made him feel like he had shot himself in the foot.

"Oh, then keep complaining."

While she was distracted, Muzan forcefully pulled her leg out and turned to leave.

Yukina stood there, maintaining the posture of her small hands embracing him, watching his rapidly disappearing figure, her eyes slowly, slowly widening.

In the end, they turned into two bewildered, beady eyes with huge question marks on them.

(⊙o⊙)？

Is it possible... like this?

Dad only said it was okay to complain, but he didn't say that the person being complained about could just walk away and ignore them...

This is completely different from the script she had envisioned!

According to her understanding, the person being blamed should feel even a little bit guilty, or at least offer some explanation.

Then she can take the opportunity to continue persuading him, and even achieve the goal of playing swings together?

Why is Dad acting so unpredictably?

Her little brain was overloaded again, and she felt deeply confused by this unconventional approach.

After an unknown amount of time, the space in a corner of the courtyard rippled slightly, and Nakime, holding a biwa, appeared silently under the cherry blossom tree.

"Nakume-neechan!"

Yukina, who was sitting on the swing, swaying gently and listlessly, suddenly brightened up.

She immediately jumped off the swing, ran to Narumi, looked up at her with a bright smile, and greeted her.

Nakime was clearly taken aback, a hint of surprise flashing in her eyes hidden beneath her black hair.

Why did you wake up so early this time?

It seems like only a few years have passed since she was last placed here in her slumber.

This is quite different from previous records of periods of dormancy that often lasted for decades.

Yukina didn't notice Nakime's surprise; she was worried about having no one to share the swing with.

Upon seeing Nakime, she immediately forgot her minor unhappiness, reached out her little hand, and naturally took Nakime's hand that wasn't holding the biwa, gently shaking it and beginning to act coquettishly:

"Nagime-neechan~ You're back! Do you want to play on the swing? That swing is so much fun! When you sit on it, the wind blows around you and flower petals fall on your head!"

As she spoke, she looked at Nakime with bright, expectant eyes, her little face full of "Let's play together, let's play together."

Nakime looked down at her hand that was being held, and then at Yukina's face, which was full of enthusiasm and expectation.

She remained silent, neither pulling away nor answering, simply letting Xue Nai pull her along, somewhat dazed, as she followed her toward the swing.

"Sister, why don't you try sitting on it? It's very stable!"

"I'll help my sister push, very gently!"

"Look, the petals are falling, aren't they beautiful?"

"Please, sister, please~~"

After a few words of coaxing and persuasion from Xue Nai.

Nakime, who was usually taciturn and only knew how to obey orders and control space by plucking the strings of her harp, actually sat on that swing, which was obviously too childish for her, in a daze.

The swing swayed slightly, bringing a strange and unfamiliar feeling of weightlessness.

A few pink and white cherry blossom petals drifted down, brushing against her long black hair and pale cheeks.

"Nakume-neechan, are you ready?" Yukina asked from behind her, her little hands resting on the back of the swing chair, her voice filled with barely suppressed excitement.

"I'm going to start pushing now!"

Nakime nodded and gripped the ropes on both sides of the swing tightly with both hands.

She hadn't really thought about exerting any force. With her abilities and the swing's range, no matter how much effort Yukina put in, it would probably be like a gentle breeze rustling a willow branch.

until…

A small, forceful "Hey!" came from behind.

A force far beyond expectations, unlike anything Xue Nai had ever experienced before, suddenly came from the back of the swing chair.

The swing swung forward with a speed and height far exceeding her expectations.

? !

Miss Yukina's strength has increased considerably since she last woke up.

Fortunately, this swing was constructed by her using blood demon magic; if it were an ordinary swing, the rope would have already broken.

"Wow! We're flying so high! Nakime-neechan, is it fun?"

"Isn't the shower of petals beautiful?"

"Do you need me to apply a little more pressure?"
