Demon Slayer [Kny] Y/n X Tomika

Two years later
Y/n pov

I've been told I'd have to go on a mission with.. Giyuu Tomika, He was the most hated on Hashira. Why do I have to go on a mission with him?! Anyone else can! But being the second strongest Hashira has to have a lot of missions.
"Sir! Why do I have to go on a mission with him?!" I yelled
"..." Tomika stayed quiet
"My child..It's a mission no complaining" Kagaya Ubuyashiki Said
"Yes master.." I said as I gotten up and walk out of the room
"Ah! L/n!! I hope you do well on your mission L/n!" Mitsuri said
" Ara ara~!I wish you do well too" Shinbou said
"Ah, Thank you mitsuri and shinbou" I walked away grabbing my katana and Haori
"L/n is so cute!" Mitsuri squirmed
"Ara Ara, I have to agree." Shinbou Agreed

Halfway to their destination

"Can't believe I have a mission with this loner.." I said
"Why.." Tomika said
"Hm?"
"Why do you hate me so much?.."
I was shocked for a moment. I didn't know what to say, I kept quiet, ignoring Tomika the whole way.
As we reached the destination. Tomika quickly disappeared
"Huh?.. ugh" I ran away to fight demons. I didn't care about Tomika's disappearance, but maybe I was falling inlove with him…
"A demon slayer? Hahaha!! You look so weak" a demon said
"The only one here that's weak is you.." I sliced the demon's head off in one flick of an eye. These demons disgust me..

A few minutes of killing demons

I've found tomika.. I'd quickly slash but Tomika's sword stopped me.. He was protecting a demon?!

"My my Tomika! Why are you protecting the demon? You know you're breaking the rules." I added a smile
"..." Tomika was still quiet
"No answer?" I said annoyed
"Maybe this is why people don't like you, Tomika." I said teasing him
"I am.. Not disliked by people" he said
"Ah! Pardon me Why don't you talk to people?"
"Hey Tanjiro.. if You can still walk go run while you can" Tomika said, The boy with the demon was running away
"Tomika…💢 Why are you protecting a DEMON?" I said very annoyed
"..."
"No answer.. again? I'll just have to kill the demon myself" I said as I jumped into the moon night sky going tree to tree And Getting caught by Tomika as he held me.
"Ah! Tomika! 💢 Let me go Tomika.." I said
"... I may be breaking the rules but no.." he said
"Well then.. what's making you protect the demon?" I said
"it happened 2 years ago.."he said
"My my Why are you bringing things back from the past?" I said, I instantly done a move to pin Tomika to the ground until—
"CAW CAW!! I NEED A DEMON AND A DEMON SLAYER NAMED NEZUKO KAMADO AND TANJIRO KAMADO"
"Eh? 💢 " I said, Tomika had letted me go, I was still annoyed As we walked to the main area of the forest I seen a boy with a boar mask, a yellow haired boy, a boy with a scar on his forehead, and a demon in a box.
