Sabito's Little Sister

"You can't hear that?" Tanjiro questioned.

"No, I- Watch it!!" You pulled Tanjiro by the haori as Genya moved out of the way. "We'll talk about this later! You guys need to find the main body while Mitsu-chan and I fight this one. I'll back you up!"

Flame Breathing, Fifth Form: Flame Tiger

The dragon-like trees coming towards Tanjiro and the others were burnt to a crisp, and Mitsuri flipped above, cutting the remaining ones. She was quicker. You noticed something under her neck. Some crest.

"READ THE MOOOODDD!!"

You turned and saw that Genya had just uprooted a tree and threw it... with his bare hands. "Well!" You turned back to the demon. "I guess they're fine!"

Flame Breathing, First Form: Unknowing Fire

You sliced the wood trying to wrap around you. "Mitsu-chan, they should almost be done! Do you need me to cover?!" She shook her head. "No, save your stamina!"

"Tanjiro, Nezuko!!"

Your eyes widened and you looked. "Mitsu-chan, I'll need to step away for a second." You ran off and listened for Genya.

"I'll chase you to the depths of hell and cut your head off..!"

"That works too." You ran towards the sound, but bumped into someone. "Ow- Muichi-kun!" He turned. "Y/N! Are you alright?" He helped you up and you grabbed his hand. "Tanjiro, he's-" You panted and wiped blood from your forehead.

"Tanjiro's in trouble, and he- Haganezuka-san?" You looked him up and down. "What happened to you?" He lifted a sword and you looked in the direction you heard Tanjiro. "No time for that, can I borrow this?"

"HAH?!"

Muichiro followed you and you sprinted to where you heard Tanjiro, looking down from a low cliff. "Tanjiro!" He looked up and you threw the sword. "Use that!!"

"No, don't use it!!"

"Haganezuka-san!"

Tanjiro lifted the sword and sped towards the now larger main body, slicing it's head. You looked up at the lavender sky. The sun was about to come out. "NEZUKO!!" You jumped down and ran towards her, rather slowly.

You were about to topple over.

"No... Nezuko!" She sat next to Tanjiro, the sun's rays hitting her cheek. Her skin slowly burnt and you teared up. Tanjiro wrapped his arms around Nezuko, the headless demon running towards the village.

Nezuko abruptly kicked him off, smiling through her bamboo. "No..." You ran up to her and wrapped your arms around her, her snuggling her head into your chest. "Don't worry... you'll be fine."

After a little bit, you felt that she had stopped burning away. "H-Huh..?" She looked up at you, her face fully restored. "N-Nezuko!" You hugged her as her bamboo fell out of her mouth. "Y-Y/N!"

You gasped and looked at her smiling face. "Mo.. Morning!" She greeted. You helped her up. "But you-! The sun..!" You put your hand over your mouth, tears forming in your eyes.

"Nii... chan..!" Your eyes lit up. "Right! Tanjiro will want to see this!"

The two of you walked towards Tanjiro and his eyes lit up. "N... Nezuko?" He practically threw himself on her, wrapping his arms around her. "I thought you were going to die! Thank the gods! This is great!"

"So great."

"Yes!"

You smiled. "Very... very great." Suddenly, Tanjiro fell forwards and everyone gathered around him. "Tanjiro? Oi!" You shook his shoulders and Nezuko put her hand on your shoulder. "I'll... carry."
