Also known as: 正义恶魔, 正義の悪魔
The Justice Devil is a Devil that embodies the fear of justice. They are the secondary antagonist of the War Devil arc.
This tag is used for both the the Justice Devil itself as well as humans that have been transformed into monsters by the Justice Devil's powers. The former is currently hypothetical, as the Justice Devil has yet to appear in person.
Nothing is known about the Justice Devil's personality, except that they tend to contract with anyone who sees their actions as "right" and "justifiable" (such as the Class President (Chainsaw Man) and Yuko (Chainsaw Man)) regardless of the actual morality behind their actions.
