To LOVE-Ru, B-gata H-kei Recommendations
They're not similar in any way, I know, except for the fact that they're ecchi. In fact, they're the ecchi-est anime I know!
Both animes are about a girl trying to get a guy. Both animes have other girls liking the main guy. Allthough To LOVE-Ru is a little more ecchi. I think both shows are great. The girl is naked in front of the guy in the first episodes in both shows, You should definitly watch both of these if you liked one of them.
