I've just commented in the previous chp about the significance of the pov of these important characters to the overall plot especially since a lot of the main events/large scale conflicts do involve them. They are long-term antagonists and they need pov scenes to show what kind of person they are. Do people really want one-note evil-for-the-sake-of-being-evil kind of boring villains? These 2 chps have important scenes that foreshadow some conflicts and clashes of perspectives with Makoto later on, these characters pov scenes aren't only build personality for themselves or just about them, these povs are required to build the pov and character of MC and gang too. The novel version is translated far enough for people who got impatient to see where the stories go, but those who do not enjoy pov of non-MC-and-gang characters will continue finding this not enjoyable enough, because these 2 chps won't the only chps that focus on side characters, and the novel has many chps like that too. IMO, I honestly think the further the story goes the less enjoyable this manga/novel would be for casual readers who prefer to read fighting scenes, OP abilities throwing and killing, and fantasy coolness because this story will go deeper and talk about more philosophical stuff, ideologies, politics and even existential stuff (which all of that require povs of these important side characters as a foundation to give Perspectives from different angles and stuff).
