In this chapter, we learn about the rebirth system. It's a system that allows people to be reborn in order to become a hero again. In other words, it's basically a way for people to get a second chance at life after they've been kicked out of the first one. In this case, it means that people can be reborn into a new body, which is basically a new race of people. It also means that the people who have been kicked off the first race are now reborn into the second race, which means that they're going to have to fight their way back to being a hero.
