Giyu no longer has an inferiority complex. He doesn’t blame himself for everything anymore. His style has changed. He seems happier, but he’s still an introvert, and he’s still kind of quiet. He’s also weaker than before because of all his injuries from Muzan, and he will die at 25 because of his demon slayer mark. He also lost one of his arms. The only other hashira surviving are Sanemi, Tengen, you and him.
