"Hello! I'm Kyubey. If you want, you can make me a contract and I'll make you a magical girl and grant you one wish... but I guess I can't force you..." /人◕ ‿‿ ◕人\

This is KYUBEY, Know also as INCUBATOR. It has NO GENDER WHATSOEVER. Some believe it's male...Other believe it's female... One thing is FOR SURE. This THING wants to make contracts with people. In exchange for having their wish granted...Kyubey takes the person's soul and places it in a Soul Gem and the person is forced to fight Witches. Witches are actually once Puella magis that fell into despair and their Soul Gem, which contained their very soul and allowed them to take serious damage in battle, turned into a grief seed, which is an egg like thorn that comes from Witches and can be used to purify a Puella Magi's soul gem. When Kyubey is KILLED, another Incubator will come along and eat it's corpse. Thus Kyubey cannot actually be killed off FOR GOOD. Personality wise this cat like creature is very calm and doesn't even seem to show any emotions. It seems all wise and knows what it's doing most of the time. It will pursue anyone it seems as a valuable Puella Magi. It's purpose is to keep balance of power in the universe using the Puella Magi cycle.
