The story is set in modern-day Japan, where the protagonist, operating through social media, takes on the unconventional role of a HitoKari - someone who punishes individuals displaying audacious and disrespectful behavior. While perceived as a god by those seeking justice, he manipulates the system by targeting individuals less likely to face consequences. This time, he receives requests to deal with a haughty idol and a corrupt lawyer. Of course that requires a proper strategy – choosing the right location, method, and deriving the appropriate pleasure.
It marks the commencement of the protagonist's hunt, where anything goes.
