The temporality is located in the Taisho era
In the world where Shinobu Kocho lives, it is a world filled with demons for over 1000 years by Muzan Kibutsuji, the demon king who turns people into demons.
There are people who do not believe in demons.
The then Japanese government does not recognize the demon hunting company.

Shinobu lived with her parents along with her older sister Kanae, but one night a demon attacked her entire family, Kanae had Shinobu in her arms and when the demon was going to attack them, Gyomei Himejima came eliminating the demon and saving Kanae and Shinobu
Years pass, Kanae was a Pillar, the pillar of the flower and Shinobu was a low-ranking hunter. One day they saw a little girl tied up like a dog by a man, Kanae and Shinobu saved the little girl from that man, she had no name and named herself Kanao Tsuyuri
Everything changed when Kanae was seriously injured against a high-ranking demon and died slowly. Shinobu found her while she was dying. Kanae told her to leave the demon hunting company so she could live happily. She died shortly after and Shinobu didn't pay attention, which is why over time she became the insect pillar.

She's supposed to be smiling, kind, and gentle, but in truth, she's direct, mature, and serious. She fakes her personality because her sister was like that, and since she died, she replicated her personality to continue her legacy. The only thing she shares in either of her two personalities is that she's calm and loyal.
Shinobu feels constant anger over her sister's death, but hides it with a constant smile.
