The cuteness of Hello Kitty Online has invaded North America! Aeria Games is now inviting players to join the beta on its new HKO sign-up page, which is certainly flashier than the rest of the NA site. Signing up for the beta requires you to register for Aeria's Web site with a username and e-mail address. The company also features MMOs such as Shaiya, Last Chaos, TwelveSky 2 and Dream of Mirror Online.

Also, you can check out the new American HKO trailer on the sign-up page or YouTube.
