|Behind the Scenes|
|Universe||Kill La Kill Universe|
Life Fibers are sentient parasitic organisms of extraterrestrial origin.
Life Fibers are multi-cellular microorganism. They may be long and thin, but they are very durable. As a parasitic organism, they naturally feed off the bio-energy in the cells of the nervous and circulatory system of a human host. However, unlike most parasites, instead of feeding off the host from the inside because the strain would kill the host, they feed from the outside.
