The Different Story Witches
While a number of witches appear in Puella Magi Madoka Magica: The Different Story, the vast majority of them remain unnamed. Below are images of the various witches that appear throughout the series in order of appearance.
Unnamed Witch 1
The second witch shown and the first witch Kyoko fights. It's presumed this is the same witch Kyoko fails to defeat in Drama CD 3 since the Minotaur Witch uses decoys just like the CD Witch. Kyoko also remarks in the manga how she won't let it get away this time. Her use of a decoy is similar to Charlotte; her true form is her axe.
A group of familiars Mami and Kyoko fight. They don't seem to have a witch.
Unnamed Witch 2
A witch Mami and Kyoko briefly fight.
Unnamed Witch 3
A witch who resembles a postman.
Unnamed Witch 4
Unnamed Witch 5
Unnamed Witch 6
The witch of one of the unnamed magical girls from the beginning of the manga. She's the younger sister. She's described as a pin but it's unknown whether that's her witch type.
There's a bonus drawing of the two sisters at the end of the manga. The text alongside them reads: two sisters, both magical girls, and both also witches. The white one is the older sister, and the black one is the younger one. The elder sister captures prey and liquefies it, the younger sister then turns that liquid into nectar. One is a pin, while the other is a pincushion. They'll be together forever, friends forever.
Unnamed Witch 7
The witch of one of the unnamed magical girls from the beginning of the manga. She's the older sister. She's described as a pincushion but it's unknown whether that's her witch type.
