I find it funny how many people are against slavery in the comments lmao half of those slaves in series gets a better life then people in our prison system IRL lmao idk why people are complaining, most of the time the slave system is a joke, its literally just used as a cheat shortcut for MC to get a companion for their journey without the author actually having to do alot of work of lets say creating a actual new char that eventually becomes mc's friend and joins them aka its lazy writing in some sense
