One idea could be focusing on the reactions of the side characters to the Shield Hero's actions. For example, how the merchants in the town react when he starts to gain more power and influence. Another could be the reaction of the other heroes when they realize the Shield Hero's true strength and capabilities.
Begin by choosing a character whose reaction you want to focus on. It could be a major character like Raphtalia or a minor one like a random villager. Then, think about what that character's personality, beliefs, and goals are. Based on these, you can start to imagine how they would react to an event in the story. For instance, if you choose a villager, and the event is the Shield Hero building a new village, the villager might be initially suspicious but then become grateful as they see the benefits. Also, don't be afraid to add your own twists and interpretations to make the reaction unique.
