To Be With You Forever (Douma x Kotoha)

★Encounter★

"Uncle I want you to teach me!" Inosuke asked Kokushibo "well you do have talent but" Kokushibo went to a big wooden box filled with ninchirin swords "Well it's good to know how to use a sword other than fighting with your fist only but first what do you want me to teach you? I can tell it's not just how to use a sword because I thought you how to use a sword" Kokushibo said as Inosuke Nods "I want to know how sword breathing works!" Inosuke said eagerly "Any reasons why?" Kokushibo asked "I want to be able to fight against some demons that Grandpa let loose to humanity it's to of course defend myself Incase I encounter one at night if I thought of traveling in the future Grandpa agreed!" Inosuke said with anticipation "ok then let's start your training" Kokushibo said as they went and ask permission from Kotoha and Douma of course they supported as long as Inosuke doesn't overdo it

{Training Arc of Inosuke}

"Since you've had endurance, stamina, and strength training from Akaza I'll teach you the basics of Sword breathing that every Slayer knows you can derive it into anything as long as you do the basics you can even create your own breathing technique" Kokushibo said as Inosuke nods "I understand Uncle" Inosuke said "Douma really thought you well in manners, reading and writing huh?" Kokushibo said with a scoff "Of course you've all educated me well!" Inosuke said with a smug face "Still a mischievous one still" Kokushibo said as he messes Inosukes hair "Hey!" Inosuke shouted as Kokushibo just smiled "You've grown a lot Inosuke" Kokushibo said as Inosuke smiled and replied "Yeah"

Later on Inosuke trained hard as he is now given his first sword "Today you'll get your own sword and you will try your first time killing a demon" Kokushibo said "Don't worry these demons loss they're own humanity and are man eating kinds of demons" Kokushibo reassured the worried Inosuke "I can't help feeling guilty Uncle I feel like if I kill a demon I'm killing one of my family" Inosuke said as his fists were closed "It's alright these demons are not one of us remember those demon that lose rationality or humanity is ok to kill, if they a demon is near but did nothing to you then do the same, if a demon is just fighting back or seemed like it's protecting something with rationality then un arm yourself" Kokushibo said as Inosuke nods obediently "I will keep it stuck to my mind" Inosuke said as Kokushibo smiled "That's good now choose what feels familiar to you" Kokushibo said pointing to the table that he laid all the ninchirin swords on as Inosuke chose two swords instead of one "You want to be a dual wielder that's a first" Kokushibo said amuse "hey Uncle can I change up things on my sword?" Inosuke asked as Kokushibo just nods letting Inosuke do what he wants to do with his new swords

Inosuke took a rock and banged it on the edge of his sword making them pointy "That is" Kokushibo said as Inosuke grinned "I saw how you transform your sword to have these kinds of edges and how they are cool and can cut more faster" Inosuke said as he held his swords high "That's clever thinking of yours is good" Kokushibo said as Inosuke smiled widely

{In a different place}

"Mom!" A girl screamed as she watch her Mom getting killed by bandits held as she held younger siblings corpse near her "What a cute girl you are" one of the bandits said as he lifts the girls chin "Mom I smelled blood what happened!?" A boy with a scar wearing a checkered Yukata rushed to the door after coming back from selling cole "Nissan!" The girl yelled as the bandit lifting the girls chin grinned and his group went to the boy and started to gang him up "run!!!" the boy said as he caught up to whats happening as he punch one of the bandits turning they're attention to him "You little!" The leader of the bandit shouted as they went to beat up the boy as the girl rushed to a room where her baby brother was the only one's the bandits didn't killed yet and couldn't help but cry taking the advantage they're brother gave them "I'll call help stay strong Nissan!!!" The girl said as she holds her baby brother as far away as she can and stumble across a boy as well seeming to be the same age as her brother "You!" The girl yelled as her forehead was bleeding and saw the boy turning to her direction and started rushing to her "What happened here!?" The boy said immediately bringing out some bandage and ointment "your a swordman right!" The girl yelled straight away "Please help my brother we were attacked by bandits and he used himself as bait to help us out please!" The girl begged as she was bleeding severely while holding her baby brother that's crying so much as the boy looked at the girl and nods "rest for now and I'll go help your brother" the boy said as the girl looked relieved and passed out

Later as the girl woke up she was in a room and then she looked around and saw her baby brother and older brother on her right sleeping as she smiled and heard the door of the room sliding "It seems you've woken up" a beautiful woman with black Raven hair with green emerald eyes entered with a tray of porridge "don't move to much you just have been turned because their was no other way I hope you will understand" the woman said as the girl was confused "what do you mean miss?" The girl asked as the woman looked at her with a worried face "You were nearly dead when my son brought you and your siblings here so we had no choice but to use the last method" the woman said looking apologetic "I...what was the last method if I was near death miss?" The girl ask "Turning you into a demon" the woman said as the girls eyes widen as she had a look of disbelief "a-a demon? So li-like those man eating demons?" The girl asked frantically "No your a different kind dear you fought so hard to survive and man eating demons are those with no rationality or humanity" the woman explains as the girl look at herself as she still looked human as she feels her face and the woman Infront of her hand her a mirror as she looks in the mirror she was surprised after hearing many description about man eating humans she looks normal apart from her eyes and nails "I'll explain things so you can understand" the woman said as she started explaining the difference of man eating demons and demons that can surpress they're own hunger that is the main reason where they get stronger can change they're way to get stronger without needing to eat human flesh or human blood for instance eating wild animals, sleeping, or eating other demons, and about Muzan and his story

"But you will be back to being human after miss Tamayo comes back" the woman reassured the girl as the girl sighed in relief "so I'm the second type of demon?" The girl asked as the woman nods and smiles "thank you" the girl said with gratitude "no its my pleasure to help" the woman said as teh girl asked a question "I forgot to ask can I know your name?" The woman smiles and nods "my name's Kotoha Hashibira and your's?" "I'm Nezuko Kamado!"

"Are they ok now Mom?" Inosuke asked as Kotoha smiles "They are" "how did the girl handled the news" Inosuke asked worried "she's ok and is happy to be alive" Kotoha said as Inosuke smiled "My boy is such a good man" a voice of a man said as Inosuke rushed towards the man "Welcome back Dad!" Inosuke said as Douma chuckles and holds him like a baby "Hey Inosuke" Kotoha watches this and started to remember how Inosuke was like this back then when he was a little child always eager to hug Douma when he comes back 'times never changed' Kotoha chuckled softly watching this beautiful scene
