Maohritsu Chu-boss Yousei Academia

During a time when humans and demons waged war for dominance, the demon king ruled not only ordinary demons but also powerful mid-bosses stationed at key locations. As heroes grew stronger, they began defeating these mid-bosses, forcing the demon king to create even more formidable ones. In response to this need, a particular demon emerged, using her intelligence to establish a training academy dedicated to producing mid-bosses for the demon world.
