In this sequel series to To Love Ru, Princess Lala's younger sister Momo begins her own marital machinations to ensnare poor Rito. But to make her plan a reality, he has to become king of their interstellar empire, which would allow him to marry as many women as he wants! As Rito's heart continues to waver between Lala and his first crush, Haruna, Momo finds herself unable to deny the feelings she has for the hapless earthling high schooler. Could a human alien harem be the solution to all their problems?
I checked -- the author of this series is the same as for the original To Love RU series. Something happened; he lost his muse. The stories in the original series were enjoyable. In this series, they are just inane. Occasionally a flash of the original, but not often. Fan service rules the day in this series, and even that is inane.
