Byakuya Gang Arc
When a group of self-proclaimed noble thieves began making various heists throughout Konohagakure, their act of distributing their stolen wealth to the poor began gaining much support from many of the villagers. Even more, swarms of protesters began emerging in the village against various legitimate companies, fuelled by the Byakuya Gang's claims of the said companies being corrupt, one of which included the Kaminarimon Company.
