Breeding
How the hell does it work?!
Though breeding is still somewhat of a mystery, the general consensus is that it requires a large amount of life energy, making it only possible to occur a few times a year at most without killing the parents. It's theorized that both Kage partners will give a piece of themselves towards the creation of new children bodies, while one or both parents will actively seek out lost souls to plant into their new children. Another theory is that they mate just like normal mammals, but through some magical process the babies receive a former soul-- though it does not explain same-gender Kage breedings. Overall, there are many rumors and ideas and even some far-fetched tales about how Kage actually breed.
In the end, all is known that is is an intimate act that leaves them in a weakened state, generally in dire need of their next life energy fix.
