Teresa (TERESA) is a witch from Puella Magi Madoka Magica Side Story: Magia Record. Although the witch herself hasn't appeared in-game yet, her familiars have and her name is known from game files.
Minions of the witch of pendulums. Their role is to perform restores. Concentrated lumps of hospitality that use their own bodies to repair the witch’s broken parts. They’re not really doing it for the witch’s sake in particular, though. They seem to simply enjoy the act of repairing, and they show hardly any discretion when it comes to broken objects besides the witch.
