Makomo suddenly leaned in close and sniffed Ryuya suspiciously, as if trying to detect Nezuko's scent on him.
"Stop that."
Ryuya lightly pushed her forehead away.
It wasn't just Makomo who looked suspicious.
Tanjiro's family was staring at him too.
Just as the atmosphere grew awkward—
Bang!
The door suddenly swung open.
A snow-dusted, dirt-smudged Tanjiro stepped inside.
"I'm home."
Startled by the noise, Ryuya instinctively turned.
Their gazes met.
Tanjiro froze.
"...Sorry! I've entered the wrong house!"
He immediately stepped back outside in confusion, then looked up at the house again.
"Huh? No, this is definitely my house."
"Brother, you're not wrong!"
Shigeru ran out and pulled Tanjiro back inside.
After Makomo explained everything, the awkwardness finally eased.
Dinner Under the Kotatsu
Soon, under the warm light of the hearth, Nezuko and Kie served a simple but hearty meal.
Everyone gathered around the kotatsu.
"Let's eat!"
Tanjiro's family and Makomo clapped their hands together in unison.
Ryuya paused for half a beat before copying them stiffly.
Nezuko couldn't help but giggle.
She had imagined Makomo's master as a stern, intimidating samurai.
Instead, he seemed like a refined gentleman.
Those rose-colored eyes of his were especially striking.
If she looked too long, she felt like she might get drawn in.
As she ate, she secretly observed him.
She was curious about his martial skill.
And even more curious—
How did he know her name earlier?
"Nezuko, here."
Ryuya picked up a piece of meat and placed it gently into her bowl.
"Th-Thank you..."
She lowered her head shyly and took a small bite.
"Is it good?"
"Mmm."
Nezuko felt her heartbeat quicken.
Why was he paying so much attention to her?
Among all the family members, he seemed most attentive toward her.
It made her both uneasy and strangely warm.
"Master, Makomo wants some too!"
Makomo pushed her bowl forward with a pout.
"That's unfair! I want some too, Brother Ryuya!"
The three younger Kamado children extended their bowls in protest.
"Ryuya-san, I'm sorry. They're a bit spoiled," Kie said apologetically.
"It's fine, Auntie Kie."
Ryuya calmly served everyone in turn.
"Tanjiro, this is yours."
"Huh? I get some too?"
Tanjiro stood up abruptly and bowed deeply.
"Thank you!"
Ryuya laughed awkwardly.
"For a second I thought you were going to kowtow."
As Tanjiro straightened up, Ryuya's gaze fell upon his earrings.
The Hanafuda earrings.
A red sun with white rays.
Ordinary at first glance.
But they had once belonged to Tsugikuni Yoriichi, the founder of Sun Breathing.
They were also the very symbol that struck fear into Muzan Kibutsuji and Tsugikuni Kokushibo.
A thought suddenly formed in Ryuya's mind.
What if he wore those earrings himself?
What kind of expression would Kokushibo make?
And Muzan?
The corner of his lips curved into a faint, mischievous smile.
Tanjiro's family inexplicably felt a chill.
Dinner somehow felt heavier after that.
The Hinokami Kagura
Later that night, under falling snow, Tanjiro prepared to perform the Hinokami Kagura.
Torches surrounded him.
Flames flickered brightly against the winter darkness.
Dressed in ceremonial attire, Tanjiro stepped forward with solemn focus.
The air shimmered with heat.
As he raised one leg and began the movements—
Ryuya's eyes narrowed slightly.
The Hinokami Kagura.
It was not merely a ritual dance.
It was the sword forms of Sun Breathing, passed down secretly through the Kamado family.
Each step.
Each turn.
Each breath.
Ryuya watched closely.
Very closely.
A bold thought surfaced.
If he carefully observed every movement—
Could he replicate Sun Breathing himself?
The firelight reflected in his rose-colored eyes.
Curious.
Calculating.
Interested.
The dance continued.
And Ryuya did not blink.
