Following the adventures and trouble that surrounds Lala Satalin (princess of Deviluke stellar empire) and her unwilling fiance Rito Yuki (a mere human), and friends. The story from "ToLoveRU" continues with a lot of fun caused by Lala's scientific research, friends, and Rito's sister.
It's worth watching, but its boring after the first episode. I found it that way. Could be more interesting, a better story, and it would have been fine.
