It has been decided that Saitama’s Japanese voice actor Makoto Furukawa will perform the ending theme song for One Punch Man Season 3. The voice actor previously also performed “No map but I’ll be back,” the ending song for Season 2. It was previously confirmed that JAM Project, which performed the opening songs for both of the previous seasons, will also be performing the new one.
Studio J.C Staff is again in charge of the animation, following their work on Season 2. VIZ announced that they acquired the rights to the anime for North America, Latin America, and Oceania. The anime recently revealed a new visual for Garo.
