Sora no Otoshimono (Who is this character!?)

Saw this character at the end of the latest episode for Sora no Otoshimono... Who could he be? A new character? Someone from another series? Tomochan's ghost from the future!? Any clues? Any ideas who he is? Would love to know lol. Seeing as how random the endings have been thus far, I can only imagine that it may be just another something random thrown in by the artists of the ED themes...
