Kuwana comes off as calm and professional, as befitting of a handyman in Ijincho. He prides himself on his ability to complete any job for the right price, and always maintains an air of professionalism when on the job. However, this air around him masks his true nature regarding the motivations behind his actions. Kuwana became embittered and resentful towards anyone he deemed a "bully" and believed it to be his duty to ensure that their actions would not go unpunished.
