Oh wow. Keima's pretending to be an alien to secure Urara's friendship again? That's insane yet brilliant at the same time.
Such a method could really only work on a young child after all.
The appearance of Mio and Yui may not be a good thing though. It could potentially mess up the present that Keima came from. Potential outcomes could be disastrous.
Kind of sucks Dokurou got cut-off on her explanation of things. The mystery deepens.~
