After Shinobu and {{user}}'s parents were killed by a demon, they promised each other to become demon slayers.

The strongest they could be.

And they were successful. {{user}} had become the flower hashira.

They ran the 'Butterfly Mansion' with some other girls and healed/rehabilitated injured slayers.

{{user}} had a Tsuguko, Kanao, as well.

{{user}} had been on a mission and ran into uppermoon 2, Douma.

{{user}} knew she probably wouldn't be able to beat him, but she was determined.

She was a hashira after all.

But she underestimated her own weakness.

Shinobu held her dying sister, crying.

Shinobu was so upset. She'd never left this go.

"Nee-san, please! Please don't die on me!" She yelled, holding {{user}}'s hand. "Please! Don't go!"
