Shinobu Kocho, still fuming, forcefully slurped down a few mouthfuls of noodles.
They tasted like nothing.
In fact, she nearly choked on them.
"I'm not eating anymore!"
She shoved the bowl aside angrily.
Kanroji Mitsuri had already finished hers and was now staring longingly at Shinobu's untouched noodles.
Several times she wanted to reach for them, but she felt too embarrassed.
"Mitsuri, you can have it."
Shinobu had spent the day with her and already understood her appetite.
"It's not enough anyway. Take it."
Ryuya casually pushed his own untouched bowl toward Mitsuri as well.
Human food was meaningless to him. Tasteless. Unsatisfying. It barely registered as a meal.
He had only arranged this dinner to keep an eye on the two of them.
"Really? You're too kind!"
Mitsuri's eyes sparkled as she began eating happily.
Even now, she was trying her best to remain ladylike.
Ryuya knew she was restraining herself.
"Um… Ryuya…"
"Hm?"
He tilted his head slightly.
Shinobu's face flushed faintly as she asked, "How did you create Moon Breathing?"
She had no knowledge of Kokushibo. In her understanding, Ryuya was the only one who used Moon Breathing, so she naturally assumed he had created it himself.
More importantly—
She wanted guidance.
She had been trying to develop her own Breathing Style for a long time but had made no progress.
"Why is Sister Shinobu asking about that? Oh… don't tell me you're seeking my guidance? Hmm?"
Ryuya smirked.
Given that she had previously tried learning Water Breathing from Tomioka Giyu, it wasn't hard to guess her intentions.
"W-Who's asking you for guidance? I was just asking casually!"
She gritted her teeth in embarrassment.
Damn Ryuya.
Was he a worm in her stomach?
How did he know everything she was thinking?
"Oh? Just asking casually?"
He smiled faintly.
"Then should I guide you?"
Moon Breathing wasn't his creation.
But Frost Breathing—the style used by Makomo—was.
In other words, he did have experience creating Breathing Styles.
And he understood Shinobu's potential better than anyone.
"Whatever. It's not like I begged you."
She turned her head away and pouted.
"Fine, fine. Who told me I dote on Sister Shinobu so much? I'll guide you."
"Really?"
Her head snapped back instantly.
But the moment she saw his teasing expression, she snorted and looked away again.
She refused to let him think she was looking forward to it.
Meanwhile—
Mitsuri had already finished three bowls.
She stared blankly at the empty dishes.
Still hungry.
Very hungry.
"Boss, five more bowls of ramen."
Ryuya spoke casually.
After all, this money had originally come from Gyokko's pot.
Why feel bad?
When the bowls arrived, he pushed all five toward Mitsuri.
"Is this really okay?"
Her hands clasped together excitedly.
He was handsome.
He was generous.
He was considerate.
She was completely moved.
"Eat as much as you want. I'll satisfy you no matter how much you eat."
He laughed lightly.
Mitsuri was important.
He needed to nurture her goodwill.
"Wuwu, I like you so much! You're such a good person! I don't even know how to repay you!"
She spoke while chewing, her words slightly muffled.
"If you truly want to repay me, there is a way."
"Tell me! As long as I can do it, I'll try my best!"
"Then become a demon."
Ryuya smiled.
"Become… a demon?"
Mitsuri froze mid-bite.
A strand of noodle dangled from her lips.
"No!"
Shinobu immediately grabbed Mitsuri's hand.
"Mitsuri already agreed to join the Demon Slayer Corps. She's mine!"
"Oh? Young Miss Mitsuri joined the Demon Slayer Corps to find her destined person, didn't she?"
"Mmm… yes."
She nodded shyly.
"In that case, you could still find your destined person as a demon. How about it?"
"Mitsuri, you can't. Demons eat humans. Remember what I told you."
Shinobu tightened her grip.
Mitsuri snapped back to reality.
"I can't eat humans! I don't want to eat humans!"
She bowed apologetically.
"I'm sorry. I can't become a demon. But I'll repay you in other ways!"
"Ryuya, stop targeting Mitsuri. You can't take her!"
Shinobu looked ready to explode.
Ryuya shrugged casually.
"Fine. But remember this favor. If I ever ask for your help, you must keep your promise."
"As long as it's not becoming a demon, I'll do anything!"
Mitsuri nodded vigorously.
Only then did she relax.
She had been afraid they would fall out because of her.
"Boss, the bill."
Ryuya stood up.
But before he could move—
A sweet, lively voice called out from the distance.
"Master, wait! I haven't eaten yet!"
Master?
Shinobu and Mitsuri turned simultaneously.
A petite girl with long dark green hair came running toward them. A fox mask hung from the side of her face, and a wooden box was strapped to her back.
She waved enthusiastically as she ran.
"Master!"
Ryuya's eyes softened slightly.
"Makomo?"
