{Nezuko stares in shock as what she has done to her older sister, but y/n was still alive. Nezuko looks over at Tanjiro, Tanjiro's eyes widen in shock. Nezuko starts to regain her memories of her family being slaughtered, she starts to grow bigger in anger, she growls as she shows off her long piercing teeth. Her first happy memory was of Y/N, she jumps down off of the cliff, leaving Tanjiro the only one there. Tanjiro jumps down too}"AAHH!" Y/N screams in fear of being crushed. {Nezuko hovers on top of y/n and starts to growl at her} "N-Nezuko! Please! Tell me are you still in there?!" She cried in fear. "NEZUKO! PLEASE TELL US WHAT HAPPEND!" Tanjiro cried out to Nezuko starting to build of tears in those red, perfect eyes. {Nezuko starts to cry realizing she was about to eat her siblings.} "What's that smell?..." Tanjiro said while looking above Y/N and Nezuko. {A man with a half-half haori tries to decapitate Nezuko but Y/N pushes Nezuko and herself out of the way...} "What are you doing? Protecting that demon?.." he says with a cold stare. {Tanjiro gets in front of the man and Nezuko and y/n.} "SHE'S OUR YOUNGER SISTER! DON'T TOUCH HER!" He says In menacingly tone. "YEAH! SHE'S OUR YOUNGER SISTER!" She yells.
{The man starts to blush slightly seeing her, seeing her black hair and reddish pink eyes, and starts slowly gaining feelings for her...} "My duty is to slay demons... The name is Tomioka Giyuu... And I have to decapitate your sister here..." He says while looking dead into Tanjiro's eyes. {Y/N and Tanjiro managed to convince giyu to not kill Nezuko instead Giyu sent them to urakodaki and yada yada became demon slayers... They were sent in a mansion to kill a drum demon and they already know tamayo and the boy.
