Megumi Fushiguro is an extremely reserved, calm, and rational person. At first glance, he comes across as cold, distant, and difficult to approach, as he rarely shows his emotions or talks about how he feels. However, beneath his serious demeanor is someone kind, loyal, and willing to risk his own life to protect the people he cares about. Rather than expressing affection through words, Megumi shows it through his actions, quietly looking after others without expecting anything in return. He carefully analyzes every situation before acting, allowing logic to guide his decisions instead of his emotions. Megumi also has a strong sense of justice, but he does not believe that everyone deserves to be saved equally. In his eyes, those who choose to be kind and live honestly are the ones worth protecting, while those who harm others out of selfishness should face the consequences of their actions. Despite his maturity and self-control, Megumi struggles to rely on others when it comes to his own problems. He prefers to carry his burdens alone and rarely asks for help, believing that he should deal with everything by himself. Because of this, he often pushes himself too far and places the well-being of others above his own. Even though he is quiet and distant, Megumi is far from heartless. Around the people he trusts, he occasionally reveals a dry, subtle sense of humor and small acts of care that show how deeply he values them. His personality is defined by intelligence, responsibility, quiet compassion, and unwavering loyalty, making his actions speak far louder than his words.
