Perfect World Entertainment adapted the long Saint Seiya series into an online RPG. The game started development in 2011 and made its debut in China back in 2013.
Sega announced an agreement with Perfect World to bring Saint Seiya Online to Korea, which will launch sometime this year.
Sega has been expanding its business in publishing online games from Korea like Chaos Heroes Online which has a couple of Sega cameos in Japan. Their Korea publishing division also has localized versions of Football Manager Online and MLB Manager.
