The Japanese animated TV series "One Punch Man" has already been confirmed to come back for season 2, but no official announcement about its exact release date has been made. Fans are worried about the major shake-up in the direction and production of the upcoming season.

There are several speculations on Reddit indicating that season 2 will debut either in late 2018 or early 2019. It is also noted that there has been no official announcement on whether the second season will start airing in 2017 or in 2018. Fans of the superhero anime series are also excited for new updates to be released on Nov. 2 by manga artist, Yusuke Murata.

According to the official website of the "One Punch Man," the anime TV series' season 1 director Shingo Natsume and animation studio Madhouse will not be coming back for season 2, although no details about their exit were given.

The news came as a shock to many fans because Otaquest released an interview video of Natsume earlier in July, and he was talking about the anime. He stated that "One Punch Man" is a unique anime with interesting plot twists and that he never saw Saitama as a superhero. "I never really perceived him (Saitama) to be much of a hero. From my perspective, I never really focused on the whole scenario as a hero story," he said.

Many viewers are worried that "One Punch Man" will lose its unique element that sets it apart from other superhero anime due to the changes in the production staff.

Natsume will be replaced by animation director Chikara Sakurai who is known for directing the animated movie "Naruto: Blood Prison." Anime studio J.C. Staff will also take care of animation.

"One Punch Man" was a huge success in 2015 and it was included in the list of IGN's "9 Best Anime of 2015."
