High school student Izumi Kawashima, whose daily routine is rating newspaper articles, finds a wallet containing a large sum of cash. Instead of returning the wallet to its owner, Izumi decides to lend a substantial portion of the money to a middle-aged male acquaintance. She eventually returns the wallet to its owner, a wealthy high-school boy named Koki, who notices the missing money, and as compensation, asks Izumi to do something for his friend – to create a newspaper that brings happiness to its reader.
The traces left by the era of the samurai are still with us today. From this rich history of this ancient warrior culture comes a tale of honor, vengeance and redemption with a dark, sense of meaningless fatality. It is the origin story of a cursed vigilante, Ai, hell-bent on disposing those responsible for her clan's demise. Inspired by the great tradition of samurai cinema, Ai is an exploration of the era of the samurai and explores the themes of dormant fury for those who have lost loved ones and are driven to the point of madness with revenge.
