Clarisse is a young female alchemist from Granblue Fantasy with a special ability in decomposition alchemy, particularly the ultimate disintegration of existence. She was involved in events with Cagliostro, where her parents initially used her against him, but she was taken hostage and experimented on by Paracelsus. Transformed by the Philosopher's Stone, she gained enhanced alchemical powers. Despite lacking traditional talent, she mastered existence collapse through intuition, using it to destroy the Philosopher's Stone and revive Cagliostro. Her ancestor lineage also struggled with alchemy, but she specializes in material disintegration.
