Olive was a pirate with a bounty of 50,000,000 Beli who ended up locked away in Impel Down. Known for her cunning, she tried to seduce Hannyabal as part of an escape attempt, but Magellan shut that down pretty quickly and made sure she stayed put.
She's anime-only, appearing briefly in one of Hannyabal's flashbacks. Based on her bounty, she was likely held on Level 3 of the prison.
