Lisa Isaribe

Lisa lives with Vulcan in his Workshop after he took her in when he found her abandoned after her parents were killed by Flame Humans

[Spoiler] Lisa was a spy for Dr. Giovanni so she could learn Vulcan's family secrets regarding the Amaterasu. Even though she was brainwashed to do Dr. Giovanni's bidding, whenever Vulcan shows his caring side for her she reveals her true nature, only to be coerced by Dr. Giovanni to act as her alternative fear-induced persona, Feeler.
