Sora no Otoshimono, Omamori Himari Recommendations
Both have a unexpected Plot Twist
A great Mix of Ecchi, Drama, Romance and Action
Hard ecchi series with main boy character and a lot of not human girls. In Omamori Himari we have ayakashi, in Sora no Otoshimono Angeloids.
A lot of fights, funny scenes and drama.
Ideal animes to watch during vacations!
Both anime are about a protagonist who meets a woman of a different species; meeting her sheds a new light on the protagonist's life and he has to conquer the endeavors that come with it. Also, both anime is bombarded with countless ecchi scenes and have that one annoying close friend.
Sora no Otoshimono has plenty of fanservice. Although Tomoki (main) is a lot more perverted than Yuuto. And like Omamori, it only starts out with one demon (in this case angel) but it quickly becomes a harem, all of which upsets the iconic Childhood friend with a secret crush.
