The Avengers is an organization in Yakuza 3. They are a group composed of former Yakuza and Hitman, whose goal is to take revenge on the Yakuza. They are mostly a sidequest group that make the bulk of the Hitman Missions of the game.
The Avengers are a group made of former underworld men who have been betrayed or disowned during their service, and thus have sworn revenge on the Yakuza. Ibuki a man who worked under Kashiwagi, directs the Honest Live Association, HLA that helps men to leave their crime lives and live an honest life. The HLA eventually hires Kazuma Kiryu to deal with The Avengers for not only they target the HLA but also are an obvious obstacle to their rehabilitation goals.
Kiryu can accepts these quests from Ibuki himself on the HLA headquarters in Kamurocho or through a man in Okinawa that acts as contact, for there are different Avengers in each zone. Hitman Missions that are composed of battles against The Avengers are mostly Boss Battles against their core members, and they make up some of the toughest and most reward battles in the game in terms of experience and money. Only one mission can be taken at a time and they cannot be cancelled once accepted. This shouldn't prove too much hindrance for most of the time when the player is given multiple choices, the Avengers available are mostly of equal strength, and only one of them has a condition to appear in Night, which is easily done in the last chapter of the game.
