Puella Magi Witch Project > Familiars
From the Wiki:
"Lesser monsters divided out of the essence of a Witch. Though normally assigned the task of maintaining and defending their parent-witch's barrier, it seems that they can eventually gain independence and stray to form their own barriers. Further growing, they take on the form of their parent."
Familiars/minions of the witch. They are a projection of the magical girl's heart before she became a witch.
They can range from being based off of loved ones, personal life, objects, or whatever, granted that it is what the magical girl loved the most. Their duties refer to whatever the person/thing they represent.
Most witches usually have 1-2 familiars/minions at a time, never 3 or more.
Only a few of the familiars are completely finished with no plans of changing. And I tend to change them a lot.
