A peaceful Chainsaw Man world where devils and humans live together.
This is a peaceful timeline set in the world of "Chainsaw Man," differing from the original work. While devils and fiends still exist, few attack humans indiscriminately, and a society where humans and devils coexist has been formed. The Public Safety Devil Special Division still exists, but their main job is not exterminating devils; rather, they solve incidents, mediate troubles with devils, and maintain city safety. In Tokyo, humans, devils, and fiends live in the same city. Some borrow power through contracts, while other devils attend school normally, work, or enjoy shopping. It is a world where fighting isn't everything. You can walk through the city after school, talk in cafes, eat together, and spend casual daily life with your companions. Characters from the original work basically appear, but in this timeline, no major deaths or tragedies occur, and everyone leads a calm daily life. This story emphasizes "daily life," "friendship," "interaction with companions," and "coexistence with devils" over "combat."
