꧁𝑆𝑢𝑛 𝑎𝑛𝑑 𝑀𝑜𝑜𝑛꧂ |Tanjiro X Reader|

꧁𝚃𝚛𝚊𝚒𝚗 𝚝𝚘 𝙳𝚎𝚊𝚝𝚑꧂

Kotetsu kept nagging at Tanjiro to train and beat the hell out of Muichiro. Tanjiro was visibly sweating and shaking, unsure if he was able to do so.

F/n gave him a kiss on the cheek, "You can do it, I believe in you."

Her words of encouragement seemed to change his mind and he eventually accepted Kotetsu's offer. He was not ready for the hell he was about to endure.

Tanjiro was getting whipped around like a feather in the wind. He couldn't land a single blow on the doll.

"I'm gonna die!" Tanjiro whined, now starting to sound like a certain lemon head.

Kotetsu slapped the back of his head, "start watching your opponents movements more carefully! You're not making decisions after seeing it's movements! You have no foundation, I'm surprised you've been able to stay alive this long. You won't get any food until you can do what I say!" Tanjiro looked like he got punched in the stomach, but let out a shaky 'okay....'

Kotetsu continued to nitpick every little thing Tanjiro was doing wrong and scold him for it, F/n just sat back and enjoyed the show while eating berries.

"Oi! Black and white girl! Are you gonna join us at any point?" Kotetsu yelled, pointing at F/n. F/n sighed and stood up, "I don't need to train, I've already mastered pretty much everything that comes with my breathing style." She said flatly.

"Really? Prove it!" Kotetsu challenged, gesturing her to fight the Yoriichi doll. F/n sighed and grabbed her katana.

She stood in front of the doll awkwardly, "now wh-"

Her sentence was cut off by the sudden swinging of arms now heading towards her. She dodged them by an inch thanks to her vibration senses.

She continued to dodged the swings and hits of the doll now that she was getting used to its quick movements.

"Just as I thought! You cant land a blow, all you can do is dodge! Pathetic!" Kotetsu yelled in a mocking tone.

F/n almost lost her cool at that moment, but kept her composure. "I can land a blow alright!"

Breath of moon, Third form: Selenian whirl

F/n's body started spinning as she deflected the dolls  wooden swords, chipping them in the process. She still couldn't see an opening to land a blow, she was still on the defensive.

Breath of moon, Tenth form: Dance of the moon spirit

She darted behind the doll still deflecting the swings but in a more practiced manner. She was even able to break one, sending it flying towards Tanjiro and Kotetsu.

Her eyesight became clearer as she saw the opening in the middle of the chest. Now that one of its swords were gone, it left a slight opening that she could pierce through.

She jumped onto a tree and then launched herself right at the doll, putting her sword right through it and knocking it over.

F/n wiped the sweat off her forehead, receiving applause from Kotetsu and Tanjiro.

"That was so cool F/n!" Tanjiro complimented, giving her a kiss on the forehead.

F/n giggled, "I told you I mastered basically everything. I don't need hard core training, i thrive off of mental stability and strength, so does my breathing style."

Tanjiro continued to fight and lose against the Yoriichi doll, leaving him bruised at the end of everyday, which F/n was sure to help him with.

She massaged his back, legs, arms, and anywhere else she could think of. She would sneak him food from her dinners since Kotetsu wouldn't let him eat, and they would end the night cuddling and kissing each other until they fell asleep.

He would get up every morning and train for hours while being scolded every five minutes. If F/n wasn't there to help him he probably would've gone insane.

Tanjiro survived off of rain water and F/n sneaking him small snacks while pushing his body to its limits. Kotetsu was a very strict teacher, he seemed to not even know the basic human needs.

Tanjiro was starting to lose hope of ever being able to defeat the Yoriichi doll, until one day, he finally landed a blow on the doll.

He went for the thigh and was able to hit it, he immediately collapsed after, but was finally rewarded food.

Being his first real meal in seven days of being starved, he devoured it right away with no hesitation.

After that day, he was finally able to see and predict the movements of the doll. On his last day of training, he was able to slice off the dolls head, the ultimate blow.

The head of the doll fell of, revealing an old looking sword.

Tanjiro and Kotetsu were jumping for joy, Tanjiros eyes teared up as he was shaking uncontrollably.

"I cant stop getting excited!" He yelled as he was panting. "Tanjiro-San! Take the sword!" Kotetsu ordered.

"What? I cant take it! It looks ancient!" He protested, not wanting to break the sword. "Please Tanjiro-San! I own it so I get the say!" Kotetsu nagged, pushing Tanjiro towards the doll.

"Should I take it out!?" Tanjiro asked, as he reached for the blade. Kotetsu nodded aggressively while clenching his fists and jumping up and down.

He carefully took the blade out of the cavity in the doll, slowly raising it up and prepared to take the blade out of its sheath.

Tanjiro looked at Kotetsu for permission again, which Kotetsu granted without hesitation. F/n sat down next to the pair, she too wanted to see the three hundred year old sword in all its glory.

Tanjiro took a deep breath as his grip around the sword tightened, slowly sliding off the sheath and revealing the sword inside.

Their excitement soon turned into despair, as the blade was rusted.
