Margaret

Margaret is Igor's assistant in the Velvet Room as well as a main character in Persona 4 Abridged.

Biography
Like Igor, not a lot is known about Margaret or the Velvet Room which seems to be her place of residence. Each time she is shown, she is sitting in her spot in the Velvet Room with Igor. She helps Igor stay on track with exposition and assisting Yu. She has the power, just as Igor does, to enter Yu's mind in order to directly inform him of some of his latent abilities or to sass Igor when he's trying to help. At this point in the series, Margaret has not been shown leaving the Velvet Room which means that she has been alone in the Velvet Room with Yu before when Igor has not. It appears as though, while she is more competent in some regards than Igor, she is still learning the trade as Igor has been shown teaching her how to give tarot readings.

Margaret does not seem to be a fan of her job. She is almost exclusively annoyed at Igor in any interaction between them, considering times when he sleeps moments of solace from his frustrating tirades. She has a cooler head than Igor, and while she says it's best to humor him, she tends to do a lot behind his back. She sent him to rehab once, informed Yu while Igor was asleep, and told Yu that he could fuse personas without needing to visit Igor in the Velvet Room to piss him off.
