As a waifu, Makima isn't great visually imo. She has red hair and an office outfit minus the jacket. Nothing much there to really gush over.
Personality-wise though she's fucking fascinating and compelling. She's a complete mystery in her intentions, motivations, and even raw power level. She can go toe to toe with eldritch demons that represent primal fears in humanity, and she still works basically a desk job at a demon hunting agency. She has more power than any other character in the series so far by a wide margin and has settled on Denji, someone who has demonstrated that he isn't anything truly special beyond his simplicity that leads to victory. The woman is a book written in invisible ink, and the more that we get to see the more I get invested in her as a character.
