Eureka Seven: Eureka

Eureka is a Coralian in human form, sent by the sentient Scub Coral to understand and communicate with humans. She treats Nirvash not like a mere machine, but as a living being, with consciousness and feelings. However, she can seem distant and awkward to other people - she has trouble communicating with other humans and understanding their feelings. She tends to appear randomly next to people, startling them at times.
