One night, Keima is in his room when he picks up a certain game.  On the cover is a very poorly drawn heroine, Yotsuba.
Will this game change the world as Keima knows it?──
Keima Katsuragi, the god who has won the hearts of many girls.  Will he finally see his ideal ending...!?
Yotsuba:  For some reason, 
that makes me happy...
Yotsuba: Por alguna razón, 
me hace feliz...
Yotsuba: No sé por qué, 
pero me hace feliz...
