I recommend owari no seraph! Season 2 just got released! Anime K is also awesome! It's currently airing the second season and before u watch the second season(K:REturn of Kings), u have to watch the movie first.(K:Missing Kings). If u like reverse harem, them i recommend Diabolik Lovers, and its currently airing 2nd season (Diabolik Lovers, More Blood). Another reverse harem that is currently airing is Dance with Devils. I hope u enjoy these animes! XD
