Nebula is a new character that may appear constantly with crossovers and stuff. She doesn't really belong to one manga as an OC. She lives with an older human nine tailed kitsune with gold fur named Kyoku and Nebula is her student. Nebula is impatient and clever, but not yet wise. She is kind but hot-headed but is a genius and a quick learner. Nebula is often rude at times. She's 50 years old but looks like a ten year old.
Kyoku on the other hand is kind and gentle but is straight foward and extremely pateint. She is not easily madened or surprised, since she is over a hundred years old (but looks like she's in her late teens ;]) and knows magic far beyond Nebula's comprehension. She sometimes speaks in riddles and helps people by granting wishes, payment is normally never taken for selfless reasons.
This is Nebula. ;3
