Aniplex and Dengeki G's magazine are currently teasing an original anime project, set to be revealed in a cover and feature story in the July issue of Dengeki G's, which goes on sale in Japan on May 30. The first hint has been revealed on the site: "The theme is friendship."
Don't get too excited about the headline image, that's just the May 2012 issue of Dengeki G's. Here's the Hollywood Squares-esque lineup of hint boxes.
A new hint will be released every two days, if anyone fancies themselves a super sleuth and wants to keep up with it. A TV CM is also set to air on May 4, which could just end up being a vague teaser since it precedes the actual announcement.
The theme of friendship may not be much to go on, but at least we know when to expect the official unveiling.
