I'm dumbfounded at how bad this story and the logic of the MC is. She's actively trying to save the woman who helped her out after her "reincarnation", yet willingly follows a stranger into the woods without protest. The fat pig-lord will be most likely in a large, extravagant building, most likely either in the center of the city, or near the opposite side from the main gates/road. It would most likely be surrounded by pretty shady guys since this is a cliche and all.
