Galanet also known as Gpotato Japan acquired the license to publish Iris Online yesterday March 28, 2009. I believe this game will be a bigger hit in Japan than Korea due to the amount of influence of Otaku-ness and Anime. Not only that it has plentiful of Loli and cute chibified super cute kawaii character which will be a big plus to most JP gamer community, no pun intended. I myself enjoyed the Korean Closed Beta testing of this game if you're interested on gameplay videos then I've got them for ya.
Check the link above if you want to find out more information about the game along with real gameplay videos of the Closed Beta taken straight from the Korean version. Only the Korean site is available as of now, no new information yet as to when Closed Beta for the Japanese version will start nor when the website will be up. Check back next time~
