Katsuya Serizawa

He was bullied and outcast during his earlier years due to his psychic abilities which caused his self-esteem to crumble. This left him without social skills and confidence, Serizawa was a grown man in a vagabond's attire who lives tormented by his immense power. He lived locked in his room without leaving it because like Mob he did not want to hurt anyone until a mysterious man named Claw appeared. Serizawa warned the mysterious man about how dangerous it is to approach him but the man was not afraid. The man took him out of his messy and dirty room to see what the real world is like. Unfortunately it was raining. The man shows Serizawa an umbrella. Over the years, Serizawa took care of that umbrella with his soul and Serizawa, having so much power, was categorized as a "Super-5" which led him to be recruited by Claw. Despite being grateful to Claw for giving him a sense of belonging, Serizawa is plagued by self-doubt, constant anxiety, and the belief that he is not worthy of love or respect. It is not until he meets Mob that he begins to question his motives and seeks to find true happiness in his life.
