Level-5 And The Puzzling Black Box

Level-5 recently filed a trademark for something named “Black Box” in Japan. The name is registered in both Japanese and English, and written several different ways, including “Black Box,” “Box” and “B-O-X.” Level-5 are looking into opening an office in North America, so perhaps this is a projects they intend to self-publish overseas?

What can you think of related to Level-5 that this could be? We’ve already got Professor Layton and the Diabolical Box. Perhaps Black Box is another service of some sort, like ROID?
