Kiko is is a type of kitsune found in Japanese folklore and mythology, believed to be the first stage of evolution for good-aligned kitsune and have obtained a state of power that causes them to shed any physical body they may of once had and become pure spirits, they are below the Kuko and Tenko but serve the Shinto gods faithfully (usually Inari).
Kiko are slightly more mischief-prone than Kuko or Tenko but much less so than the "wild" kitsune, they tend to take the form of brilliant white foxes with up to nine tails but can appear as anything they desire due to their spiritual nature (they often change into beautiful women).
