Aimed squarely at males, the game involves several scantily clad female characters with names like "Word Angel" or "Grammar Angel" who help players in their respective areas of English study.
Users progress through the story by playing games and answering questions. There are also fully animated cut scenes, most of which revolve around a young male student in varying degrees of undress with the aforementioned "Angels."
Owners of the Moe Star can register for the events through the game's website. As one could expect, there are no plans to release this outside of Japan. Ever.
