Raijin followed along his father's instruction to slice the fishes in the most accurate way possible to be sold in the market. Before this, for the last month, Raijin went along with his father to the market to learn about the trade and sell his hand made crafts out of bamboo in exchange for some science books.
Raijin was very knowledgeable than any kid of his age, in the field of science. Because of his mastery over the way of the thunder art, he knows his physiology really well and uses it in his favour to test medicines and anti venoms he made over his trips down the hill and the river to fish. This made him quite famous in the village dispensary as he treated any wounds, broken bones or venomous bites with ease.
Raijin was now 11 years old and his birthday was day after tommorow, winter had started again as usual on his birthday and people started going home quickly.
Raijin followed his father on the path back home after having sold all the fishes in exchange of some goods like utensils and money , and the money they earned was much more than any day.
'Hmm, I've earned quite a hunch , it's Rai's birthday , I should ask him to be in the village for the whole day tommorow and we would celebrate his birthday on the morning of day after tommorow ' thought Arashi.
"Raijin, it's the Snow festival tommorow, would you be willing to do the work for the village tommorow and all the trade? I would like to take a rest , I'm getting old afterall"
"Sure dad! No worries, you can rest for tommorow and take no worries, I'll manage everything"
Both Father and Son duo reached their house and had to hear an earful because of the mess they had created on their clothes while fishing, but Arashi showering his love on Atsuko spared him and his son.
Due to the cold, they all gathered in the dining and had a dinner together to get warm and have a good time.
When Raijin slept, Arashi explained the plans to his family members, when Raijin had no idea, afterall he had forgotten his birthday. (￢_￢)
The next morning, Raijin got up early, freshened up, and did his training for 2 hours , packed up a bag with clothes, his bottles of handmade medicines, fishing rods and some food.
He ran down the hill to the river, fished and sliced them up and went on to the market to start his day of hardwork.
Time went on as he sold the fishes , did the trade for goods and started helping out the villagers for the festival.
"AAHH" Raijin heard a scream echo the village market area as his quick eyes got a glance of an old man falling. He disappeared in a blur and reached the old man mid air and landed safely on the ground.
As he looked up, he saw a ladder falling onto him but before he could react, with a pair of hanafuda earrings , a man clad with a green and black haori with long black hair with red tips appeared in front of him and held the ladder with an arm.
"Thanks Tanjuro-sama" "No problem Raijin"
He helped me up and I made sure the old man was fine. But then as soon as I looked at his face, I came to a respectful bow. It was the village head.
"May god bless you Raijin, I've heard from your father this morning, he sent me a message, you can live with me for tonight and start leaving with the sun rising. I was just decorating my house when I lost my balance. Thank god you and kamado was here-" said the head with a gentle smile.
"Its a responsibility of mine as a member of the village sire, I have to look for my fellow people"
"Alright Raijin, let's finish up the work, the sun is setting and the celebrations are about to begin"
Raijin went on with his work with Tanjuro sama following him, "How's tanjiro now?"
"He's doing fine, I'm ill so i came to the festival , he's doing the work for today"
"Alright kamado sama, enjoy, I'll go ahead and finish up my work"
(Raijin is 2 years older than tanjiro here and tanjuro lives a little longer in this universe)
Raijin completed his work and celebrated the festival with the villagers and helped out here and there during the entire evening. As the festival ended everyone started hurrying home and Raijin too followed the village chief to his home.
"Sire? Why are the villagers in such a hurry?"
The head halted, then quicked his pace while Raijin followed him with ease. "Demons" he said. "Demons?What are they?"
The head reached his house at the centre of the village and urged Raijin to follow him inside.
Inside, the house was very spacious and luxurious, and tanjiro was led to his room and told where the bath is.
Tanjiro put his bag down in the room, went to the bath to freshen up and changed to his pajamas to sleep. The question still stuck into his mind so he looked around for the head.
He found the head in his room (He sensed to be more accurate) and knocked the door. The head allowed Raijin to enter.
"So sir, what's a demon?" The head looked at him, sighed and went towards his bookshelf. He took out an old book, dusted it off and handed it to Raijin. "I'm an old man now kid, it's now you will find all you need to know in this book"
Raijin took a bow and took the book to his room. He read the book till there were no more lights inside the rooms and then proceeded to turn off his and put the book back in his bag and slept.
He read about Demons, how strong they were, the demon slaying corps protecting people from them and how Demons were born from the one person "Muzan Kibutsuji" .
Back at his house, Arashi POV
'Yeah everything is set, just have to wait till Raijin reaches tomm- ' "AAAAAHHH" A scream from the outside living area. I looked at my father and carefully walked down to ground the floor with him and saw the horrifying image. A guy with formal clothes and a hat with his hand stretched out had put a huge one lined slash on the wall...but that was not it, my wife, sister and mother were cut to pieces.
"Your ancestor recommended the doctor to heal me, you must know the place the blue spider lily is"said the monster. He had red eyes and long curly hair as he removed the hat"
"What are you talking about you peice of shit?" Asked my father. Enraged.
"Guess you don't , killing Kaminari family was useless then and now too-"
I dashed to him and gave him a roundhouse kick out of the house through the roof. My father followed by jumping high and kicking him straight into the snow.
"You killed my wife,my sister and my mother you fucked up imbecile. I'll show you what the Kaminari Family is." I dashed to him with a punch and so did my father. I shot an uppercut and he punched his abdomen.
He was strong. He got up like it was nothing.
"Father. Dont hold back." We went together in again.
I kicked his chest and my leg punched through it, father punched his arm off.
"You are strong eh? Become a demon and see how more strong you can be-" I punched using my entire force and blew his head off.
"Its over " I said and headed to see my wife and I sensed him. Behind me. With an open mouth and hands stretched out. But how- I kicked his chest through, punched his head off- "He's a demon. Their king. " Said my father , without an arm , bleeding.
That hit me. Enough. Whether he's a king or not , he's going down. He slashed and I blocked his arm, but resulting in a gash on my forehead and my hand being a bloody mess.
"I can't let him move, if he moves, I'm dead."
I kicked him away and jumped back, crouched, closed my eyes and brought in the thunder. I dashed and hit him with blinding , unpredictable attacks from all sides. I saw his flesh,muscles and everything burning off and regenerate at the same speed.
"Enough with playing" He said and grabbed my limbs with tentacles of flesh and spikes. Out of his back. I couldn't understand but now I couldn't move too. He looked at me with a look of disgust.
*riippp*
My limbs were ripped off. I was numb due to my excessive use of the Art.
"What a waste of talent" said the monster and left.
Back to Raijin
Raijin got up when it was still dark,packed up, changed and kept a letter of thanks before leaving. He ran towards his home, with the bag on his back now heavy with goods, but it was effortless.
As hr reached the house, smell of blood filled his nostrils. And the view was horrifying. He saw his father limbless, his grandfather without an arm, bleeding. He saw both of them were breathing and brought them inside to tend to them.
Inside- the view was worse. He saw his grandfather speaking-
"Go to Mount Kawanari, there, give this letter to the old man, I've bled too much, but i'll say this to you. Do you know Demons kid?"
"Yes."
"Muzan did this-" before he could complete he passed away.
"Kill that imbecile Rai, be strong and be a good man" said his father on his lap, before closing his eyes.
Raijin wailed till his head ached , his haori of white with black branches now red due to the blood.
As he decided to bury his family, he heard footsteps.
