The Denpa Men: They Came By Wave

Radio waves are all around you. However, what you might not know is that, at any and all times, mysterious little creatures float around near these waves. They're called "Denpa" Men. You can't see them normally, but you can find them and catch them with your Nintendo 3DS. This is a role-playing game in which you collect Denpa Men to form a party, and use this party to explore dungeons.
