[Demon Slayer + Jujutsu Kaisen] [Lighthearted, Heartwarming Comedy + System + Slightly Beloved by Everyone + Max-Level Expert]
Otonashi Kawari is a noble young lady who has been able to see curses since childhood. Her mother died when she was two, she awakened her cursed technique at five, and her family was wiped out when she was nineteen. During her escape, a courtesan she'd once saved brought her back to the Tokito House in the red-light district. A curse then left her unconscious.
In the thirteenth year of her long sleep, her primary soul returned, and Kawari woke up.
After taking in the memories of this life, she turned the brothel into a teahouse, rewrote the thousand-year feud between demon slayers and man-eating demons as a storybook, and sold wisteria-themed merchandise all over the country.
Word spread that an unparalleled beauty had arrived at the Tokito House, every bit the equal of the top oiran at the Kyogoku House.
And so, people came calling.
The impeccably dressed Demon King fixed his gaze on his prey. “I have a gift of eternal life I'd like to give you, beautiful lady. Become a demon.”
“Smack!” Kawari slapped him.
Muzan Kibutsuji, half his face ruined: ???
The four-armed, two-faced King of Curses leaned forward lazily. “You're an interesting woman. Submit to me.”
“Thud!” Kawari kicked him.
Ryomen Sukuna, half his body gone: ???
*Ryomen Sukuna does not die
*The entire story follows the Demon Slayer timeline
*Jujutsu Kaisen characters come from various parallel worlds in the future timeline
*Obanai and Mitsuri stay together
*Some characters are treated rather unkindly
