Yushiro sat in his room, writing some stuff that he needed to get for Tamayo by the end of the week. He wrote it down messily down since Tamayo's cat was literally stepping on his paper. Yushiro groaned, he leaned his head into the palm of his hand. „Go disturb (Y/N). I have no time momentarily!". He hushed the poor little cat away, concentrating again on the list he had to finish. That's when he felt that someone still didn't wanted to leave him. „(Y/N)!!! Come here right now and take Chachamaru!". Soon footsteps could be heard, and as Yushiro guessed, you were running towards his room. „What is it Nii-chan? Is Chachamaru annoying you again?". He definitely was annoyed, his scowl said it all. Without wanting to make him more angry, you picked the cat up and immediately left his room.
Chachamaru purred as you patted its head. „Uh..you little trouble maker, never leaving Yushiro to do his work, huh?". As a response Chachamaru meowed. You walked further along till you reached your room. „There you are (Y/N)-chan, I've been searching for you", a lovely voice said, making your attention peak up. „Oh hello Tamayo-san! So why were you searching me?". Before Tamayo spoke, she reached her hand out to you, „Follow me my dear kid". That said, you followed the lady demon to the dungeon. Tamayo sighed, her smile faltered a bit. „I think you wonder why I took you down here, right?". You nodded and Chachamaru then jumped off your arms. „Well it's about Yushiro. I know that there will be a day when I Muzan is going to kill me, but I want you to learn something". She motioned you to come nearer and examine the works and books that were laid on the table. „But..what do you mean with that Tamayo-san?". Your voice cracked a bit but you contained the nervousness inside you.
„I will teach you the things I know, and then you'll be able to use it against the upper moons or even Muzan. And that's when you'll also have to keep Yushiro under control..no matter what it takes". Tamayo looked at with a serious face after finishing her sentence. „Okay Tamayo-san! I will do everything I can do make you proud!!". Tamayo was always like a mother figure to you since the day she saved Yushiro and you. Your brother may had feelings for her, but she was a mother that you never really had. Chachamaru jumped back into your arms and meowed. „Thank you (Y/N). Please do your best as long as I'm here". You went up back and crossed paths with Yushiro. „What where you doing down there without Tamayo-sama's permission!!". His harsh tone made you back away as Tamayo too, came back up. „It's okay Yushiro, she was with me. No need to worry". Tamayo smiled gently and passed the both of you. And so you went to your room, leaving Yushiro to do his own things.
{time skip, like a long one}
Yushiro slid down the wall as you still watched the scene in front of you. Nezuko hugged her brother close as they spilled happy tears. That sweet silence was broken when you heard light sobbing. You turned around and saw that Yushiro was holding onto Tamayo's hairpin and whispered: „It's finally over Tamayo-sama". His words touched your heart, clenching onto your uniform you had. „Yushiro...nii-chan..". You ran up to him, crying together in happy tears. „(Y/N)..my little sister...come here". Basically you threw yourself at him for the best hug the both of you shared. Yushiro gripped onto you tightly, feeling so relieved after such a nerve wrecking fight that you were safe and alive and that Tanjiro was saved. „I'm so proud of you..so is Tamayo-sama". You sobbed uncontrollably into his shoulder, feeling the ease from the bottom of your heart. „T-thank..y-you...I l-love you..s-so much nii-chan..". Yushiro lifted your face and gave you the kindest smile ever and that got you too smiling.
„I never had any doubt for the two of you. Your bond may not be like Tanjiro-kun's and Nezuko-chan's...but it is definitely something special. Stay together forever till the end for me..will you?". Tamayo smiled softly, the feeling of relieve and happiness was clearly seen on her beautiful face. She smiled a last time before all disappeared...
