Hotaru:A red and black sword,I've never seen a mixed color sword before,though I didn't see a full red sword, seeing a mixed sword is very rare
Y/n:Thank you He bowed and hotaru left and immediately as he left,y/n raven came in
Raven:You have a mission y/n sama,go northwest,it is said that women are being taken
Y/n:A mission,okay He immediately left the house and looked at it before leaving
{Northwest} Y/n had landed on a rooftop to see tanjiro talking with someone and as he finished talking with the person y/n landed next to him
Y/n:Yo tanjiro Tanjiro:Y/n, you're here Y/n:I guess we got the same mission Tanjiro: Yeah Y/n:So girls are being taken Tanjiro:Yeah,but why would a demon take girls
Y/n:Have no idea,demons normally come at night, let's scout the place by then
*Night time* A girl was walking and suddenly below her opened in a portal and she was about to fall in when she disappeared and a demon came out of the portal
Demon 1:Huh Y/n:You know it's dangerous to walk at night
She blushed at how handsome y/n was
Girl:S-Sorry Y/n:tanjiro get your friend to take this girl
Tanjiro:Okay The guy took the girl away Demon:Who are you two Y/n:The killer never.... He flash stepped to beside the demon Y/n:his name He slashed at the demons head but the demon entered back into the portal and appeared in a different position
Demon:*gritting* Tanjiro: What's that annoying sound Y/n: I'm gonna pound its teeth Tanjiro:Total concentration water breathing Fourth form: Striking tide!
He went to attack the demon but it went into the portal and appeared behind y/n and grabbed his feets but y/n cut off its hands then kicked it out the portal
Y/n:demon breathing:fourth form:Demonic rampage
He killed the demon as two more portals appeared
Demon 2:You killed him Demon 3: That's what he gets for over feeding
Tanjiro: They're more Y/n: We'll just kill them A portal opened beside him and was about to grab him but then the demon was kicked away
Y/n:Huh a demon Tanjiro:Nezuko! Y/n:"why's he carrying a demon,no I'll deal with that later"
Demon 3:huh a demon helping a human,human what are you
A portal opened below tanjiro and he fell in
Y/n:Tanjiro! Demon 3:he he we've got your friend Y/n:Dark breathing Third form:Devil's illusion
The demon was in a dark place Demon 3:What,where am I Y/n:dark breathing:Eight form:Dark wings
Suddenly feathers were impaled into the demon as he spat out blood and the illusion wore off and y/n flash stepped and was about to cut his head off when he heard...
Tanjiro:Wait y/n! Y/n:huh Tanjiro:I wanna ask it a question Y/n:Fine Y/n dragged the demon out if the portal and banged his back on the wall and held him
Tanjiro:who is muzan kibutsuji Demon 3:i-i can't tell you Tanjiro:why Demon 3:I can't!he put a spell on me I can't say anything about him or I'll die
Y/n:You're about to die Demon 3:I won't say Y/n cut off his head Y/n:Useless Next he pointed his blade at nezukos neck
Y/n: Explain Tanjiro: She's my sister,she got turned into a demon
Y/n:Does she crave human blood Tanjiro:No she sleeps to restore her energy and to cease her hunger
Y/n took away his sword Y/n:*sigh*you do know that a day will come and the hashiras will come for you both and if possibly me
Tanjiro: You're coming with us Y/n:Yeah, it's boring being alone Tanjiro:Yeah, let's go,oh and here He gave that boy a piece of kimono Tanjiro:Is that your sisters Boy:*crys*yes Y/n:Come on tanjiro! Thanks for reading
