Chainsaw Man Church

The Chainsaw Man Society for World Peace, or just The Chainsaw Man Society, is a project developed by Fami alongside an unknown third member, with the intention of aiding Chainsaw Man to prevent the upcoming Age of Devils prophesized by Nostradamus and achieving a "world without evil." Fami is the supposed brain of the group, whilst Haruka Iseumi's role is solely to attract more people to the cause. As of such, Haruka is the only member of the three "leaders" that isn't fully aware of the meaning behind their actions.

According to Yoshida, whilst the movement was initially founded and composed of diehard supporters and refugees from Devil attacks, its numbers exploded due to its popularity among high school students. The group also accepts donations for their campaigns, both from civilians and politicians.
