Disclaimer: I do not own Samurai Jack, nor Demon Slayer/Kimetsu no Yaiba.
Author's Note: This story takes place, the moment when Tanjiro leaves his family to sell charcoal.
"You may have beaten me, now... but I will destroy you in another lifetime." Aku said as he lied helpless and physically damaged in his lair.
"You won't live in another lifetime, Aku." Samurai Jack said, ready to end the monstrosity such as Aku.
"I disagree." Aku smiled, then let out a screech. White rings exited Aku's mouth and hovered over Samurai Jack's head a few feet higher.
Samurai Jack stared at the white rings that hovered over his head. "What trickery is this?" He asked. The rings then moved down and surrounded Samurai Jack's body. Samurai Jack then swung his katana forged by the Norse God, Odin... the Egyptian God, Ra... and the Hindu God, Rama. Samurai Jack's katana had no effect on the rings that surrounded his body. Then, Samurai Jack felt the ground under him disappear like a trapped door had opened beneath him. "Aku!" Samurai Jack yelled as he had fallen into a pit of light.
Aku snickered, then rose up within his fiery lair. "Do not worry, Samurai. Wherever you may end up... Aku will rule everything."
Samurai Jack screamed in pain as he felt his body stretch out and curl a bit. He also screamed in failure as he had not only fallen inside of a swirly black and white vortex... but had also fallen for Aku's trap. He had not thought that Aku would separate him.
In Another World...
During winter Season... the Kamado Family had lived in the snowy mountains for all of their lives. Tanjiro Kamado, the oldest child of Tanjuro and Kie Kamado has been the sole provider for the Kamado family of seven, since Tanjuro Kamado had died from natural causes. Tanjiro has worked hard to sell charcoal to provide for his mom and his five younger siblings, such as Nezuko Kamado, Takeo Kamado, Hanako Kamado, Shigeru Kamado and the youngest child, Rokuta Kamado.
On a winter day, where no snowflakes had fallen, but the sky was very gray and cloudy.
"Come back as soon as you can!" Shigeru yelled as he and his siblings and mother had waved Tanjiro off.
"Be safe, big brother!" Hanako said with high hopes for Tanjiro.
One Minute Later...
Nezuko Kamado had approached her siblings and mother after saying goodbye to Tanjiro. She carried Rokuta on her back with a white cloth wrapped around Rokuta's body.
"Nezuko!" Hanako had chanted.
"Were you able to say goodbye to Tanjiro, dear?" Kie asked her daughter, Nezuko.
"Yes, mom." Nezuko replied to Kie. "I-"
"Hey, what's that?" Takeo asked as he pointed his left hand behind Nezuko.
"Hm?" Nezuko looked at Takeo, then followed where his hand was pointing. She then turned around to see a white ring hovering in the sky.
"Wha... what is that?" Nezuko asked as she stared at the white ring hovering in the sky.
"It looks weird..." Hanako said.
"Is that a cloud?" Takeo asked.
Kie Kamado had continued to stare at the white ring hovering int he sky. "Well, maybe it's-"
And suddenly, the white ring had begun to glow and change colors from white to black, which confused the Kamado Family. One minute had passed and as one of the Kamado Family members were about to speak... a person dressed in a white robe had suddenly fallen out of the black and white glowing portal and had fallen hundreds of feet downward. He saw a brown house and snow all around it as he was falling.
The Kamado Family had gasped when they saw someone fall out of the glowing portal.
"Somebody's up there!" Takeo yelled as he saw a man dressed in a white Gi fall from the ring portal.
While falling, Samurai Jack was able to see what he could land on, then arched his body to where he could land on his feet. Like a lucky cat. Samurai Jack had landed near the Kamado Family house.
"Aku!" Samurai Jack yelled after he landed on his feet on top of the snowy grass. "Show yourself! Aku!" Samurai Jack yelled as he gripped his katana, tightly and sharply turning his head left and right. "Our battle is not finished, coward! Come out and face me, and-" After a moment, of shifting his head left and right... he had spotted a group of people staring at him, which happened to be the Kamado Family. Samurai Jack had taken the time to cool his head and take a breather as he then realized he's being watched. Samurai Jack then lowered his katana. "Oh, uh... hello." Samurai Jack said, feeling a bit embarrassed.
There was nothing but absolute silence, until Hanako decided to step forward and speak up. "Who are you?"
"Me? Oh, um..." Samurai Jack rubbed the back of his head. "My name is-"
Author's Note: This is a What If? story where Samurai Jack had been transported to another Universe, rather than into the future by Aku. Wish me luck.
