Akumetsu’s plot begins with a teenager by the name of Shou Hazama, an ordinary, yet somehow comical and sleazy, high-school student, and his best friend Shiina Nagasawa.
The setup for the story is a near-future Japan, where excessive corruption and speculation lead the country to a massive economic downfall, increasing the public deficit to an enormous seven hundred trillion Yen. Politicians and businessmen simply enrich themselves amid growing unrest. Shiina’s family, due to crushing debts, sell their daughter into prostitution, forcing her to attend parties for the elite.
t is during one such party, attended by high-profile employees of the Ministry of Finance, that what was going to become an orgy is suddenly interrupted by a young man wearing a demonic mask, who after giving a speech on how savage and corrupted the upper class of Japan has become, proceeds to brutally slaughter one of the economic advisors by crushing his skull with an axe. Recognized by a frantic Shiina as Shou, the man simply waves the statement off as a misunderstanding, then grabs the mauled body of his victim and walks calmy to the front lobby, where he is gunned down by police and, before dying, has his head blown off by a device implanted into his own mask.
Thus, the act introduces a long, exceptionally violent campaign of murders performed by such masked individuals, targeting those who are deemed as responsible for the massive economic crisis and, as such, labeled as evil by the masked men, who all goes by the common alias Akumetsu (literally destroyer of evil).
