Kyousou Giga (TV)

Colorful animation and a plot in which the protagonists have to save the world are some of the similarities between these two anime. Also, both strongly rely in the message of true friendship and the bonds of family. Also, rabbits are a main theme. Summer Wars is more sci-fi, where Kyousougiga is more fantasy, but both are very enjoyable. If you liked one, you will certainly like the other.
