Once Warrior of Light joins the Pugilists' Guild, Hamon trains them and introduces Chuchuto, his assistant and first student. In the middle of training, the Warrior of Light discovers that an illicit drug called somnus is being smuggled into Ul'dah via Black Brush Station. Instead of the lesson he had planned, Hamon orders the Warrior of Light to track down and arrest the smugglers.They discover that one of the smugglers is actually Rurukuta, a missing pugilist who discovered that Hamon was weak and decided to leave the guild. Hamon admits that he is weak due to his age. Despite having discovered the truth about Hamon's condition, Chuchuto respects him no less and wishes to rekindle the fire of passion within Hamon.
Recent events have made Hamon deeply depressed. Chuchuto believes that if Warrior of Light were to train the way Hamon did before, they can serve to cheer up their master again. Chuchuto asks the Warrior of Light to bring wasp stings, and this reminds Hamon of his youth and expresses his fervent desire to be like his old self again. Hamon demands that the Warrior of Light fight him. As soon as the fight is over, his former rival, Weggfarr, arrives on the scene with Rurukuta. Having mocked Hamon's efforts, Weggfarr challenges him to a public rematch, with the Pugilists' Guild itself as the prize for the winner. And Hamon is determined to face Weggfarr again.
During a training session, Chuchuto and the Warrior of Light are attacked by Rurukuta and his minions. The duo manage to defeat Rurukuta and learn his true agenda. Rurukuta only wants his master to live, even if it means swallowing his pride and running away from the impending fight. Aware that Hamon is in good hands, Rurukuta says goodbye. Although he appreciates Rurukuta's feelings, Hamon is more determined than ever to face Weggfarr.
Once Weggfarr returns to Ul'dah, he is knocked down by Hamon before he even uses his axe. Not wanting to admit defeat, Weggfarr resorts to using a substance he calls pluton to increase his strength and comes at you in a frenzy. With Rurukuta fighting alongside the Warrior of Light, they defeat Weggfarr and his minions. Having realized his mistakes, Rurukuta declares that he will embark on a journey of self-discovery. Hamon asks that the Warrior of Light continue to dedicate themselves to their training, so that one day they can become a legend in their own right.
Widargelt invites Hamon and his disciples to hold a cross-discipline match between the monks and the pugilists. Hamon, Chuchuto and Rurukuta travel to the Fringes but the match is cancelled before it even happens due to the intervention of Adri and his subordinates. Later, Hamon's party finds out about the duel between Widargelt and Adri and they go there to offer their forces to defeat Adri's subordinates.

You mean to say you do not know Hamon Holyfist, the man who once ruled the bloodsands!? ...Hmmm, mayhap it was before your time. Aye, I used to be champion of the Coliseum, but these days I train young hopefuls as master of the Pugilists' Guild.Hamon, in response to being asked about himself by the Adventurer
As a former Coliseum star, Hamon Holyfist is boastful and self-centered. Even when helping train students, Hamon thinks about his own agenda, be it sending his students around the city to pick up discarded gil or asking them to practice on training dummies in the middle of the street to draw a crowd. His penchant for skirtchasing often gets the better of him. He has a warm and caring side, which he displays when he speaks of his students, such as the two he personally adopted off the street, Chuchuto and Rurukuta. He takes great pride in the accomplishments of his students, such as the Warrior of Light, whom he refers to as the second coming of the Holyfist.
