There's Angel, who is a central character with his own story arc. He has to face many challenges in this pre - main - story world. Then there are his comrades like Kasugabe. They all have different personalities and motives that drive the story forward. For instance, some are more focused on revenge against the Titans, while others are trying to find a more peaceful coexistence.
