Gaff is an Elf that is assigned to keep Lillet Blan's room clean. Gaff loves to clean, and will accidently break something while cleaning on the occasion. Gaff is one of the first people Lillet meets after arriving at Silver Star Tower, and tells Lillet the story about the scary ghost that haunts the halls. He's a little self-centered, asking Lillet to call him "handsome" instead of "cute".
At one point in the game, Lillet tells Gaff to sleep outside so he doesn't accidentally break Amoretta's Flask.
