About Makoto
Makoto Furukawa is a Japanese voice actor and singer best known for portraying cool, intelligent, and emotionally restrained protagonists. His performance as Saitama in One-Punch Man became one of the most recognizable anime performances of the 2010s thanks to its unique balance of monotone comedy, emotional subtlety, and explosive battle intensity.
