Katsuya Serizawa

Katsuya Serizawa (芹沢克也, Serizawa Katsuya) is an extremely powerful Esper, was formerly a part of the Super 5 and member of Claw. He now works at the agency with Reigen and Mob.

Appearance
Serizawa is a man of average height and build. Whilst still a member of Claw he had curly black hair, somewhat heavy eyebrows, a thin mustache and stubble. He wore a medium-grey jacket over a black shirt, along with black pants and foam clogs. He carried his white umbrella with him at all times. After the fall of Claw, he no longer carries his umbrella.

After being invited to work with Reigen and Shigeo at the agency, Reigen trims Serizawa's hair and shaves his face. When working at the agency he wears a two-piece business suit.

Personality
Serizawa is very sheltered and naive. He placed all his trust in Touichirou Suzuki and looked up to him as a personal saviour, following his orders without question. His face tends to clearly reflect his emotions. If he is separated from his umbrella, he panics and completely loses control of his psychic power, which causes heavy damage to his surroundings. He is haunted by a deep fear of his own power.

Serizawa is a very nervous person. Due to his years under Touichiro Suzuki, he seems to have difficulty acting on his own without guidance from others. However, after the fall of Claw and joining Reigen's agency, Serizawa is slowly coming out of shell and becoming more independent.

History
When Serizawa was 12 years old, he was so afraid of his uncontrollable psychic power that he locked himself in his bedroom and refused to leave. Afraid that he may hurt people by accident, and without anyone to help him learn about his powers, he stayed there for 15 years. Touichirou Suzuki finally coaxed him to leave (and by doing so, join Claw) by offering him an umbrella and encouraging him to view it as an extension of his room. Serizawa followed him, hoping to learn to control his powers and rejoin society. Instead, Suzuki used him to further the aims of Claw, leaving him and his well-being utterly dependent on both Suzuki and his umbrella. Serizawa viewed Claw as a company, Suzuki as the president, and himself as an employee.

Plot
After hearing Serizawa's past, Mob bluntly told Serizawa that he was being used. When he tried to argue in his own defense, Mob bluntly told him that he was following the wrong person. He made a token attempt to fight Mob, using his umbrella as both a weapon and a shield, but was eventually won over by the sincerity and empathy of Mob's 100% Friendship. By sharing his energy with Serizawa, Mob was also able to share his memories of true friendship with him, which helped Serizawa to understand the true nature of his relationship with Suzuki.

He later used his umbrella to save Reigen from Suzuki's wrath. Suzuki retaliated by blasting Serizawa with psychic energy until his umbrella was torn to shreds, then draining Serizawa's power to use for himself.

Powers & Abilities
Serizawa possesses extremely powerful psychokinesis, which he either imbues into his umbrella to form a shield or emits through his umbrella as an attack. Previously, without the umbrella, he was unable to control his power; he has recently overcome this issue.
