She leaned back with her head tilted with a hum, amongst the many people she faced she had never heard of such breathing.
"Unfortunately I have never heard of a breathing by that name"
He gasped in shock flailing his arms around as he tried to say something.
"I-...but-...!"
"Are you sure it goes by that name?"
Ayame interrupted, giving him the words for his next sentence.
"To be honest I'm not completely sure either, but it's what my father called it"
They were both at a loss without finding out exactly what it is it was nearly impossible for ayame to help him.
"Then do you mind showing me those techniques of yours?"
She said standing up walking towards the other end of the vast room, if they couldn't determine it by name the only way she could discover what it was is by seeing it, and luckily enough the room was wide enough for a bit of action.
"Eh?!? Right here?"
Tanjiro asked still sitting down besides the table.
"Yes is there a problem?"
"Ah no it's just I don't have a katana with me right now and I become immobile after using it"
"That won't be a problem after all you don't have any missions right now right? And as for a weapon..."
She looked down tapping her fan on her chin, her lips formed a gap as she came up with an idea. She held her fan in her mouth while she rolled up the sleeve of her kimono exposing her forearm, taking her fan back she created a deep enough cut to draw some blood.
"EHHHHH? A-ayame san?"
He stood on one knee with a worried expression, but it was quickly replaced with an expression of shock as the dripping flood solidified into a katana imitation.
"That should do it, here Tanjiro"
She said tossing it towards him. Tanjiro reached his arms out carefully catching it in his arms. He held it up with an amazed look as he giggled with a smile at ayame.
"That's incredible ayame -san! It looks just like a normal katana, is this your Kekkijutsu ?"
"Well something like that, now whenever you're ready"
"Hai!"
He stood up and took his stance taking in a deep breath through his mouth, he gazed back towards ayame with a determined look.
"Here I go ayame san"
Ayame nodded as she flicked her fan open signaling she was ready to receive his attacks, pushing himself forward he charged towards ayame unleashing a sequence of forms. After a few forms her eyebrows downturned as she couldn't recognize any of them, she continued to receive his forms until he unleashed the last one.
Her eyes widened as a silhouette of someone who had used the same form appeared behind him like a mirror "this is.." she whispered, before tanjiro could finish his attack the blood blade within his hands liquified as his grip loosened causing him to stop.
"O-oh!"
He looked up to ayame who had a worried and pained look, but at the same time it was also a hopeful look. the blood exploded into petals around them before disappearing.
"Ayame san?!?"
He asked in a confused tone.
"As I expected you really are connected to him"
Tanjiro turned his head to the side as ayame walked past him towards the chabudai , she sat down with a serious look with tanjiro joining her moments after.
"Does kibutsuji muzan know about you"
"Yes? I met him once in asakusa"
"I see"
She said with a sigh.
"Those earrings of yours as well as that breathing style belonged to a man named yoriichi, the first breath user in existence"
A look of shock appeared on his face.
"It's called sun breathing and I have only ever seen him use it once on that faithful day"
Pm
It was a dark night and it was a time when muzan was still openly active and existences of the twelve kizuki hadn't been born, and it was a time when she was still tied to him along with one other person "tamayo".
"Eh? Tamayo san? You know her?"
"Yes, she was the other demon along with myself tied to him at that time, have you met her? How is she"
"She's a really kind person she is working as a doctor right now along with yushiro a boy that's accompanying her"
"Im glad she is doing better than before"
She said looking outside towards the setting sun.
The two of them had only each other to lean on at the time, both having their lives turned into a living hell with no hope to grab on they tried whatever they could to bring that man down, with only failure as it's outcome. eventually ayame had completely lost her sense of self due to muzan's constant attempts of complete control, becoming only a shell, until they met that man.
Muzan was travelling around in search for more people to work for him, while the both of them followed from behind with dull eyes that had given up with no chance of escape, they continued to walk in the dead of night when a human man with hanafuda earrings appeared before them.
"Ho? Another swordsman who uses those strange breathing techniques, I'm starting to loose interest in you all after having killed so many of you weaklings"
Muzan said as he attacked him with long bladed tentacles in sweeping attacks attempting to kill the man, he sneered in arrogance but that feeling of power was instantly destroyed when all five of his brains and hearts were instantly cut through with a single move.
He fell to ground holding onto his bleeding neck in disbelief as it wasn't regenerating, yoriichi then caught eye of tamayo who stared with hopeful eyes at the possibility of his death.
"What do you think lives are?"
He took a step towards muzan to finish him, but was interrupted by the screeching sounds of grinding teeth from muzan as his skin burned red in anger, his body burst into 1,800 lumps in attempt to escape with only 300 left as the man was able to destroy majority of them before he completely disappeared.
Tamayo then fell to the ground crying tearing at her own head.
"You were so close you were so close, he actually conquered the weakness of his head, YOU SHOULDVE JUST DIED YOU FILTHY MAN KIBUTSUJI MUZAN"
The man knelt beside her as she wore a look of shock, she looked down at her hands surprised at the fact she wasn't dying.
"I'm not dying why am I not dying?"
She said.
"M...u...zan"
They looked towards ayame who spoke for the first time in a century, something snapped inside her head as the curse binding her mind broke she fell down screaming covering her ears.
"A-ayame"
Tamayo sat beside her patting her back trying to calm her down.
"Shut up... shut up..SHUT UP"
She screamed trying to silence the screams of agony from the people she killed in her head, with countless memories spilling forth, she could feel cold clawed hands pulling her down to the ground as tears fell from her eyes. Tamayo didn't know what to do to calm her as she nervously looked around until her gaze stopped at the man as he reached inside his kimono.
He dangled a bell in front of ayame, the serene sound washed over her like a warm wind blowing away all the gruesome screams that played in her head. She looked up with teary eyes as her hands fell from her ears.
"Is that a omamori charm?"
"Yes, a priest gave it to me and it had a nice ring I didn't know what to do to help her calm down so I took it out in impulse, I'm pleased to see it helped"
He said dropping the bell in ayame's hands, her eyes narrowed with her built up tears dropping.
"Who are you? Why are you helping me"
She whispered weakly.
"I am yoriichi though there is no need to remember that name"
"Yoriichi, thank...you"
She collapsed as tamayo held her, she then explained everything to him and what she knew about muzan.
"The curse placed upon you two might have been temporarily broken which is why she reacted that way"
"Yes... unfortunately she is asleep right now but ayame knows more about that man than I since she has been stuck to him long before I have"
"Tamayo would you and ayame like to help me defeat that man?"
She looked at him in confusion but eventually agreed.
