Nebula

Nebula is of a species known as the Wisps- a reclusive species known to generally hide from the other races on multiple worlds. They resemble humans, but are translucent, one color, and glow like gentle tounges of flame. Their beauty and magical talent have made them a very proud species.

Nebula, on the other hand, is more adventurous than most of her other bretheren, and often visits what Wisps call "The Real World". It was on one of these visits where she quite literally bumped into Ruichi, eventually becoming his inseparable companion.
