Firestorms

Yoriichi took every palladium for [Y/N] and their child.ย When heโs gone a long time helping the Demon Slayer Corps Yoriichi buys wisteria powder for her and even offered to hire a bodyguard.ย Theyโve been married for two years and everyday [Y/N] is happy and thankful.ย Sure, sheโd love if Yoriichi could stay home more but his work is important.ย The wedding ring is enough; it brings heartwarming memories until she can see Yoriichi again.
ย
ย
ย
Itโs a beautiful day.ย Taking a bag of wisteria, she waddles into warm sunlight and fresh air.ย [Y/N] loves visiting shops in town.ย The people are kindhearted.ย But now they are mournfully silent.
ย
ย
ย
Waiting in line at her favorite food stand [Y/N] overhears apprehensive gossip.ย
โSomeone in town died yesterday.โ
โWas it a demon?โ
โI think it was a human.ย But the Demon Slayer Corps sent out some swordsmen to investigate.โ
โYou think thereโs a murderer around?โ
โHowโd they die?โ
ย
ย
ย
[Y/N] wanted to ignore the icy fear latching to her bones but she kept listening as she shuffled forward.ย Maybe thereโs information she could use to avoid encountering the murderer.ย
โSplit in half.ย Burned.โ
A man snorted.ย โIf they were burned then it was probably a terrible accident.โ
โThen how do you explain how they were split in half?โย An old lady asked.
โYeah, a demon wouldโve eaten them.โ
โThe Demon Slayer Corps said it was a merchant.ย They found his bags and broken earthenware on the road.โ
ย
ย
ย
Sitting on a bench [Y/N] ate her food but a delicious meal couldnโt distract her.ย Thereโs only one merchant who visited town selling earthenware.ย And she bought something from him yesterday.
ย
ย
ย
Mr. Agawa is her neighbor.ย An old man who paid [Y/N] to clean his house and water a garden.ย Her husband always sent money from his job as a demon slayer but they now have their child to think about.ย What if Yoriichi got injured and couldnโt work?ย What if they got sick?ย What if they needed extra supplies?ย So every day, [Y/N] walked to Mr. Agawaโs house to work.
ย
ย
ย
The old man has many scars on his face โconveying that he has survived many battles.ย But heโs unlike his rugged exterior, sweet and generous.ย He sits on the porch saturated in sunlight and often talks about his brother who worked as a sailor.ย
ย
ย
ย
Looking up she sees a bird circling.ย Yoriichiโs bird!ย
โLetter for [Y/N]!ย Letter for [Y/N]!โ
She caught a parchment and unrolled it.ย Her fear vanished as she read the letter.ย Yoriichi will be home for a month!
ย
ย
ย
Mr. Agawa stood up with a cane, slowly limped over, and gave [Y/N] money.ย
She looked at him in shock.ย โI havenโt harvested the vegetables yet-โ
He waved his hand and smiled.ย โGo home.ย Youโve been separated from your husband long enough.โ
[Y/N] hugged him.ย โThank you Mr. Agawa!โย
ย
ย
ย
ย
ย
ย
ย
ย
Itโs been ages since sheโs cooked for another person.ย Outside she hears footsteps marching up the road to their house.ย She runs to Yoriichi and hugs him.ย Heโs silent as usual but his eyes gleam happily.ย
โWelcome home.โ
ย
ย
ย
[Y/N] sat across from her husband and talked about how the days have been peaceful and boring.ย Well.ย Until today.ย โPeople are saying thereโs a murderer in town.ย Iโm happy youโre here.ย I missed you.ย I feel safe from anything when youโre with me,โ she laughed.ย
ย
ย
ย
Tomorrow, [Y/N] started walking to their neighbors and hummed a tune.ย Yoriichi stopped her.ย He looked at his wife questioningly, seeing a basket in her hands.ย โWhere are you going?ย To Mr. Agawaโs?โ
โYes.ย I saved a hot meal for him since I made too much food for breakfast.ย He doesnโt leave his house much.โ
Yoriichi slung the pack over his shoulder.ย โIโll take it to him.ย Can you go into town and get me some things?โ
โSure.โย She could go buy tickets too.ย Thereโs a play at a theater.ย Itโd be fun to go see it with Yoriichi.
ย
ย
ย
On the way back thereโs a river that stretches across the outskirts of town.ย Small glimmering fish swim between large stones.ย In the distance is a dense forest.ย [Y/N] stands on the bridge dropping her bags for a minute to rest.ย Wind flew by her face carrying a scent of flowers and sereneness.ย Shrubbery moved.ย She expected to see an animal.ย But itโs a man โMr. Agawa!
ย
ย
ย
Terror shines in his eyes.ย Throwing his broken cane Mr. Agawa runs.ย A long wound is across his chest.ย Fire coils around his leg as he screams.ย He falls and scrambled on all four limbs to crawl away.ย Whoโs chasing him?
ย
ย
ย
Yoriichi emerges from the woods.ย His beautiful eyes glint dangerously as he briskly walks up to his opponent.ย
Mr. Agawa holds his wound.ย Heโll bleed out soon and his scorched leg made it impossible to run away.ย His frown turned into a bitter smile.ย โTo die by a demon slayerโฆnot the way I thought Iโd go.ย Youโฆare worse than any enemy or demon Iโve faced.โ
A sword blade severs his head from his neck.
ย
ย
ย
The demon slayer picks up Mr. Agawa and put him over his shoulders.ย Yoriichiโs gaze sweeps the horizon โand he freezes when he sees his wife.ย
โYoriichi?โย She gripped the bridge railing to steady herself.ย Heart pounding, [Y/N] wondered if running would really help.ย ย Mr. Agawa wasnโt a demon.ย He wouldnโt be in the sun.ย Why did Yoriichi kill him?
ย
ย
ย
She abandoned her shopping bags and ran.ย Her legs, knees, and arms ached as she desperately tried to sprint to the town.ย Crying, tears blurred her vision.ย
Crackling flames shot past and surrounded her.ย Yoriichi, calm as ever, walks up to his wife and offers a hand.ย โCome home.โ
โWhat?โย Intense heat and dark smoke swirl over them โa signal of looming death.ย โNo,โ [Y/N]โs [color] eyes stare at the sword.ย Blobs of blood dripped from the metal.ย โI wonโt.โ
ย
ย
ย
The smoke is scratching her throat.ย How would she escape?ย Nobody can defeat Yoriichi in battle.ย Even the strongest and smartest demons are scared of him.
ย
ย
ย
Patiently he waited.ย Even as fire trapped them.ย Tears sting [Y/N]โs eyes and her hair is waving from roaring winds.ย โWhyโd you kill Mr. Agawa?!ย Youโre a demon slayer!ย Arenโt they about honor and justice?!โ
Heartbreak is clear in Yoriichiโs voice.ย โIโm still an honorable demon slayer.ย You were in danger.โ
โWere?!โ
ย
ย
ย
โI came home earlier.ย Before I sent that letter.ย Did you know that merchant you bought earthenware from was a demon?โ
[Y/N] is shocked.
โHe had slowly gained a tolerance to wisteria powder.ย I was surprised that he didnโt kidnap you.ย He wore a disguise, said he actually liked humans.ย Wanted to learn more about them and their society.ย Made earthenware because he fell in love with the arts.ย But a demon is a demon.ย So I killed him.โ
ย
ย
ย
Sympathy grabbed [Y/N]โs heart.ย Itโs heartbreaking!ย The merchant was a demon but he didnโt deserve to be killed.ย If he had wanted to be friends with humankind, he shouldโve been left alone, unlike the other violent demons that the demon slayers attack.
ย
ย
ย
Yoriichi shook his head and smiled.ย โYouโre sweet, [Y/N].ย Thatโs why I love you.โ
Frowning she spat, โWhat about Mr. Agawa?!โ
โHe was a violent outlaw.ย A bandit.ย He stole from travelers who hardly had anything.ย Society doesnโt need bandits like him.ย And I couldnโt risk you getting hurt.โ
ย
ย
ย
โNow,โ Yoriichi reached out for her arm.ย โLetโs go home.โ
She never doubted her husband.ย Yoriichi always told the truth.ย But heโs still a murderer.ย โNo!ย I love you, Yoriichi.ย But youโre a murderer.ย I-โ
His grip is intimidating and strong like stone.ย โI canโt let you go.ย You wonโt be safe without me.โย So the pair leaves the fierce firestorm and walk back to their home.ย [Y/N] felt her feet drag as she cried, her mind panicked as she unsuccessfully tried to wrench herself free.
