On Our Way

THIRD PERSON POV

Long ago, siblings sat around in a circle in the middle of a long winter night.

"Tanjiro, Nezuko, would you like to hear a story from long ago?" A red headed father asked the two children, unable to sleep.

"Of course Daddy!" Tanjiro responded, his baby face having the beautiful signature smile he always had.

The two children climbed onto the fathers lap, being careful of his frail condition.

"Once upon a time, thousands over thousands of years ago, a woman set her first foot prints onto this earth as a demon. The very first demon to ever exist. She believed in unity of all, in peace between everyone. She was given a job to find a man to have a baby to give him the place of master demon. Around here was an area that (Y/n) visited quiet often. She's known to be a god of peace, and the demon of all demons at the same time. She has extraordinary powers that she uses for what she sees fit. When she visited this world, she left a huge impression on everyone around her. She's extremely tall and beautiful, with mesmerizing green eyes, ones that no one could forget. She later found a man, someone that she loved very dearly. She finished her job as she taught her new son what he needed to do and how to. He understood, and promised to be someone (Y/n) could look up to, but after she left he felt... Empty. He missed his mother, his father being gone, abandoning the boy to be by himself. But of course no matter how many times he tried to call out to her, she never returned. He found himself questioning everything the woman had previously said to him and started to rebel. He made demon after demon, ordering them to eat any human in sight to gain power, saying demons cannot team up together. And here we are now, awaiting for the woman's return to end this demons constant suffering." The man finished with two giant eyes staring into his head.

"That mean demon! Once (Y/n) comes back she'll kick his butt!" Tanjiro said, faking a punch to the air.

"Dad... Is this a true story?" Nezuko asked, more afraid then the little boy.

"I'm afraid so, but that woman, (Y/n), shes someone you'll never have to be afraid of. Her heart and her actions, she's the definition of pure. One day I hope you'll get to understand what I mean if you get to meet her yourself." He ended, the two children slowing falling asleep in his warm bear arms.

Back to current time

"I have no reason to believe you. Demons are and will always be monsters." He responded, picking his sword back up into an attack position.

"All demons?" I repeat, looking towards Nezuko.

"All." He replied.

"If given the opportunity, would that young woman devour her brother or protect him?" She asked, now very annoyed in a very serious and firm voice.

"I don't- She'd probably eat him!" The man screamed now also annoyed because of how long it's taking to kill the demon.

"Perfect." She said smiling, getting the exact answer she wanted. I knew she couldn't come out because of the sun so i'll just throw an invisible force field on her too. I saw her panicking through the box, trying to get out, worried about her brother.

(hey so when words are like 𝑇ℎ𝑖𝑠 𝑖𝑡 𝑚𝑒𝑎𝑛𝑠 𝑠ℎ𝑒𝑠 𝑡𝑎𝑙𝑘𝑖𝑛𝑔 𝑖𝑛 𝑎 𝑑𝑒𝑚𝑜𝑛 𝑡𝑦𝑝𝑒 𝑜𝑓 𝑙𝑎𝑛𝑔𝑢𝑎𝑔𝑒 𝑓𝑜𝑟 𝑁𝑒𝑧𝑢𝑘𝑜 𝑡𝑜 𝑢𝑛𝑑𝑒𝑟𝑠𝑡𝑎𝑛𝑑)

(Y/n) held up her hand and formed a gun with her fingers.

"Boom." She said as a fake rubber bullet shot out of the woman's fingers towards Tanjiro. To everyone else but her it looked like a normal bullet.
