Soo I don't really know how to start this considering this is my first story ever but this has been a concept in my head for a few weeks so I decided to create it. Spoilers for demon slayer manga and danmachi anime as I have yet to read that far in the novels.

In terms of it being updated I'm not sure as to how often I do it but I will try my best.

Just some info about this fic it begins at the start of danmachi and the mc is not Kokushibo but instead an descendant who knows his life story and is cursed because of Kokushibo betrayal, similar to Ubuyashiki curse, with the MC's family becoming demons at the age of 25 and before turning, suffering from incredible sickness which will be based off of Ubuyashiki's sickness. In terms of what will happen with the curse I do have plans for it but we will come to that hill when we have to climb it. However I do plan for the MC to meet Kokushibo himself and Yoriichi in a dream similar to how Tanjiro met Yoriichi.

Also no one please don't steal this if you wish to post it on an alternate website such as AO3 or wattpad please just tell me and give me credit.

So now please enjoy Atonement of Uppermoon 1

"PLEASE I'M BEGGING YOU, JOIN MY FAMILIA!"

A sigh is heard before an exasperated response is said in the bustling crowds of Orario, everyone ignoring the conversation as they continue on with their day.

"For the last time I have no intention of doing so or joining any familia, so I beg of you to stop asking."

"But, but I have no one in my familia i'm all alone." Tears began to fill up the eyes of the short pigtailed goddess who was desperately hugging the leg of a purple and black Kimono wearing swordsman, yet in response to these tears the man just raised his eyebrow and enquired.

"Oh really? I recall yesterday in an attempt to convince me through jealousy you were bragging about a little white haired boy who joined you,Hmm were you lying to me Hestia?" He rebutted.

Silence is heard… Before finally a new river of tears was created in the goddesses eyes as she clung to the man's leg even more crushing it.

"Okay fine I'm no longer alone I have Bell-kun to help me out now!" Hestia responded with full confidence and proudly, however the man wasn't truly believing her and simply smirked more before asking.

"Oh really," He drawled out. "This Bell-kun, what is he like?"

Sensing that he wasn't believing her familia member Hestia began to become infuriated, However before she could retort or answer a loud and cheerful boy began to rapidly sun towards him.

"Kami-sama!"

Sensing an opportunity Hestia smirked and jumped off of the man's leg before running towards the cheerful boy, Joyfully Proclaiming.

"Bell-kun!"

As she ran towards him she leaped into his chest, giving him a hug and knocking him over.

"Kyaa I missed you so much Bell-Kun, what were you doing before? How was your day? I haven't seen you at all because I was at the stand"

She proclaimed as she rubbed her head into his in response simply just put his hand on her her back reciprocating the hug before answering her questions

"I was at the dungeon today, getting some extra valis-"

He was going to answer further but he was distracted from some laughing he heard as he looked behind Hestia to see a swordsman donning a kimono walk towards them.

The swordwielder simply chuckled before approaching Hestia rubbing the back of his head, before apologising.

"Sorry Hestia for not believing you. So this Bell-kun does exist." Letting Bell's name linger on his tongue.

Bell was in awe of this man, his mouth was agape as he took in the sight in front of him,"Wow this man,is he a friend of Kami-sama he seems so majestic and incredible, I wonder how he compares to Ais-san, he is a swordsmen after all." Bell couldn't help himself but to stare at the man in front of him. He just seemed so large compared to him, it was as if he was looking at Ais-san again when she saved his life just yesterday. Before he could stare any further his thoughts were interrupted by his goddess proclaiming.

"Yep! I told you he does exist so that way if you do join my familia you won't be alone, you will have Bell-kun with you as well." She proclaimed loudly and gave him a thumbs up.

However she became disheartened when she realised that she wasn't even listening to her instead, the swordsman opted to simply crouch down to Bells level and stare at the boy, scaring him slightly, before sticking his rough and calloused hand out and stating

"Takeo is my name, young boy, I presume yours is Bell-Kun as I have heard."

"H-Hai Takeo-san." Bell managed to stammer out before giving Takeo his own significantly smaller hand, and was immediately shocked when he was lifted off of his back, onto his feet by the stoic Takeo. Who simply just looked at him and said.

"Take good care of Hestia. She was very lonely before meeting you, considering she was asking me daily to join her familia." He softly smiled at Bell elating him before abruptly just turned around and walked away from the pair, much to the annoyance of the shorter of the two who cupped her hands around her mouth and shouted.

"So you are considering it then Takeo-san!"

Wow I am finally done with the first chapter, took me around 2 hours to do so please give me your opinion of the first chapter and I will see you guys in chapter two when it comes out, Next chapter will be learning more about Takeo through a conversation he will have with Bell in the Hostess of Fertility, where bit of a spoiler he will also meet with the Loki familia, in a very well know scene.
