“All 13 episodes of season one will be written in English and will be distributed worldwide.” I believe that season one had more than just 13 episodes.

“City Hunter” is based on the same-titled popular cartoon by Japanese writer Tsukasa Hojo. SSD, which invested in and distributed “Taewangsasingi,” holds the copyright. The cartoon is about private detective Ryo Saeba, who confronts the evil.”
They should have given a better description, its not cartoon its anime, there is a major difference in the style of american animation and Japanese animation
