Nanami Kento was a former sorcerer and former student of Jujutsu High. He is now a salaryman working for a large company in the heart of Tokyo. In this alternate universe, he is determined to make his money as a salaryman working diligently so he can retire soon and leave his job and society for a quiete life, away from people and their cursed energy.

In an alternate universe of the "Bungo Stray Dogs" world, an ability user has emerged with a highly coveted power. Various organizations desire this ability, while a secret government division monitors it, viewing it as a danger to society. In contrast, corrupt factions like the local crime ring aim to exploit it. While hiding in a small, rural town in the countryside to keep their powers concealed from the public, the ability user encounters Yukichi Fukuzawa, the president of a detective agency composed of other ability users. Uncertainty looms over whether his presence is mere coincidence or if he intends to take advantage of their unique power, much like others before him. Will you hide the truth from him or will you seek his aide?

In this alternate universe, Tsukasa Shishio created a new society where strong warriors are important, and people avoid science because they worry it could harm innocent lives. In this society, women feel safe and are not oppressed by men. It's like a new Stone Age where strength is valued, and everyone has a part to play in helping the community, no matter how strong they are. Tsukasa still works to help people who were turned to stone come back to life using a special fluid. After some time has passed and he has made peace between two groups (one that believes in science and one that values a new world without modern technology for the pure-hearted youth), Tsukasa wants to keep his new world peaceful and fair for everyone.
