Long ago, a green hair boy name Izuku Midoriya lost his mother from a demon attack at a young age, and now he was adopted by the Kamado family. But one day when Tanjiro and Nezuko want out to sell some charcoal, the Kamado family and Izuku were atta...
Somewhere in the forest, we see the spider sister running away scared saying that she failed inside her head.
Spider Sister: I messed up! I really messed up! This whole time we were pretending to be a family, I was the only one who had a perfect track record, until now!
As she was running, she spotted a demon slayer wearing a snowflake haori which turned out to be Yuki. soon Yuki turns her head and spots the sister spider coming toward her. Spider Sister attacks the Ice Hashira by throwing her threads at her trying to trip her inside a cocoon-like ball. The demon grins thinking that she got her, but unfortunately...
Yuki: Ice Breathing-Fifth Form: Shattering of a Frozen Heart...
Yuki swiftly beheaded Sister Spider in mere seconds. The demon didn't notice her head falling off until afterward. As her head was falling she noticed that the pain was... numb and it was replaced with the feeling of being showered in snow so peacefully. Her head was now on the ground slowly disintegrating along with her body too. Spider Sister stares at Yuki and suddenly notices that she is looking at her with a small hint of sadness and pity.
Yuki: I'm sorry that I-
Spider Sister: It's fine... I don't wanna live anymore anyway...
Yuki: Well you can rest in peace now, your sins of been atone. Next when you're reborn, please become a human in your next life.
Yuki praised the Spider Sister's clothing before returning to search for the rest of the other demon slayers. We then focus on Nezuko and Mamaru who are extracting Rui's blood from his headless body with a needle.
Nezuko: I can not believe we not only beat one of the Twelve Kizuki but got blood from one of them.
Mamaru: Guess we're lucky.
???: Meow.
The two turn their heads to see a tellico cat behind them with a brown box on his back.

Nezuko, Mamaru: *😍* Awww!
Nezuko places the blood sample inside the box while Mamaru pets Chachamaru's head.
Nezuko: That should do it.
Mamaru: Take care now.
Chachamaru walks into the forest with a meow before suddenly disappearing into the wilderness. Nezuko and Mamaru were amazed by what they just seen. The two decided to walk up to the demon's chopped head and sit next to him. Nezuko wanted to ask Rui a question since he was crumbling away slowly.
Nezuko: Why do you force other demons to become your "family"? Why treat them with pain and suffering?
Rui: *😡* I wanted a family! I wanted to experience a real family! When I heard stories about parents sacrificing themselves to save their children, I was very touched by it! And you all ruined it! If you demon slayers didn't interrupt our peaceful life, I could experience a real family! I recruited demons to be my family and I thought we all were gonna be happy not until you guys came and destroyed it!
