Plutia (Pururut in the Japanese version), also known as Iris Heart, is the Console Patron Unit (CPU) of the Ultra Dimension's Planeptune. She is introduced as Noire's close friend. In her human form she is relaxed, ditzy, and hard to have a casual conversation with. However, in her goddess form her personality drastically changes. Neptune calls her Plutie as a nickname. She is very laid back and it is impossible to tell what she is thinking at any given time. Her hobbies include making stuffed dolls and taking naps. She does her job as CPU only when she feels like it, which is never. She rarely gets angry, but when she does, it usually causes trouble. Plutia, along with Neptune, represents a fictional Sega console, similar to the Sega Mega Drive. Her name was inspired by Sega's practice of naming consoles after planets.[2] In her goddess form, she becomes a complete sadist and enjoys harming her foes. Whoever comes across Iris Heart will suffer from trauma for a while.
