Kinfluid (kingenderfluid) is a type of kingender when one's kintypes are fluid, just like genderfluidity. This only works with multiple kintypes, and if said person is otherkin and also fictionkin, their otherkin side could be static but the fictional side could be fluid, and vice versa.
A similar term is Kindifluid.
