Feudal Japan

"Run! Take the children and GO!" Midoriko shouted.

"I cannot." Ahri said, pained. She held her side, and Midoriko saw that it was caked with blood.

"Mama! MAMA!" Shippo cried, reaching for his mother.

"I will protect her! GO!" Midoriko cried.

Yoko scooped up Shippo and Ninako and left Midoriko to guard his mate.

Midoriko placed her right hand, with index and middle fingers extended, in front of her pendant, then raising her hand to the upper right. It appeared in her hand, a sword—Kiboken.

"Muzan! Stop this right now!" Midoriko shouted. "Koibito! Koibito!"

The incantations slammed him to the ground over and over.

But Muzan stood, snarling, claws caked in the blood of Ahri, who now lay dying beside him.

Muzan lunged forward, ferally clawing Midoriko in the chest.

"Don't make me do this..." Midoriko whispered. "Anata..."

She stabbed him into the Goshinboku using Kiboken. "SHIKON!"

Her dying words echoed in the distance.

"And so...Mother. This is what you have trained me for?" Ninako appeared in the mist. "Your soul...and that of auntie...you shall be...transcendent."

Hikawa Shrine

"Sister! It's snowing! Isn't it just beautiful?" Kurisuta Hikawa, a girl of fifteen, said.

Kuri had long straight hair with bits of hair framed inward towards her face. There was a split in the middle of her widow's peak and she let a streak of hair on both sides frame her face in front of her shoulders. Her eyes were blue and her skin was pale. Kuri wore her school uniform, a red medium dress, black stockings and brown boots.

"Oh but it's so cold!" Reiko said, coming out, following the fox, Kit. "Kit wait! Don't go in there!"

Reiko had red hair, green eyes, and tanned skin. She wore her hair in a high ponytail with a big bow. Reiko wore the school uniform, a red medium dress, with white socks and black flats

Kit ran into the Wellhouse and sat on the shrine, then vanished, and sitting there was a young girl.

"I see I see." The girl said. "Well you're definitely old enough now aren't you. I'm tired of pretending to be a fox. I'm a demon after all."

"A demon?" Reiko said. "But Kit...?"

The girl smiled, showing fangs. "The name's Ninako."

And with that she jumped into the Bone Eater's Well and disappeared.

"Hey girl! Are you hurt?" Kuri yelled. "Was she a spirit do you think? Like Grams always talks about?"

"No...she probably WAS some sort of demon!" Reiko said.

Suddenly a strange, snakelike creature came out of the well and wrapped around both of them, dragging them in.

"C-Centipedeeee!" They both yelled.

Feudal Japan

The sisters climbed out, hand over hand, and reached a clearing in a forest.

"It looks like home, but smells different." Reiko said. "Cleaner. I like this smell."

"That looks like the Goshinboku." Kuri said. "But...somehow...it's not. A younger tree. Oh!"

Kuri almost got almost knocked over by a young demon slayer in full armor chasing what appeared to be some kind of boar demon.

Inosuke ran for his life on surprisingly fleet feet. He was wearing furs and a bit of armor himself. Reiko wondered why he didn't use the two swords at his waist. "Headlong ruuuush!"

Kuri fell to the ground, knocked asunder by the two runners. The demon slayer, Tanjiro Kamado, immediately stopped and extended a hand.

"I'm sorry." He said, helping her up. "I'm trying to slay that demon."

"Your gonna kill him?!" Reiko cried. "Wait! Don't!"

Inosuke halted. "I am NOT a demon!"

Suddenly the sound of rushing feet as gold flashed in the air and lightning struck! "Thunder breathing: First form. Thunder clap and FLASH!"

Zenitsu was aiming for the two boys, but they quickly used their own breathing to reroute him to the tree.

There was a great CRACK, as Reiko gripped her cut arm, and the blood spilled onto the trunk at the same time as Zenitsu's sword struck it.

The five stood around the tree as it split open with a flash of dark purple light. Immediately horrible shadows spilled out and rushed away; and then a round purple stone lifted in the air and shattered, pieces flying everywhere.

Kuri let out a low groan and fell to the ground.

Tanjiro rushed over to her, and she stared at her glowing hands in fear.

Inosuke stared at Reiko, who was now looking quite demonic herself, with fox ears and a tail.

He smacked Zenitsu pretty hard. "Zachew you idiot!"

"Well you two shouldn't bring girls over without inviting me!" The lecherous monk snarled.

"Well we weren't having a party!"

"OI!" Reiko interrupted. "Let's get outta here before the demon slayer decides to kill me next!"

"What about your sister?" Inosuke looked over at her. "You shouldn't leave out a member of your sounder."

"You're one to talk!" Zenitsu growled.

"She'll be ok." Reiko said. "My sister is stronger than anyone. Let's get going before he spies me. I'll send sis a message."

She closed her hand over a large leaf, destroying it with a crunch, as Kuri tapped her pocket absently.

Kuri gave her a small smile while still conversing with Tanjiro; and the two "demons" made their escape.
