Koi Suru Tenshi Angelique is the first reverse harem anime I watched. I am reviewing this based on both the seasons, Kokoro no Mezameru Toki and Kagayaki no Ashita.
There are some embarrassing moments especially at the starting of the series, for example when some guardians introduce themselves to Ange, there are sparkling around them xD which might make some girls go "kya~" fangirling...
I think this series is the best among the Angelique series. Nice art and pretty animation.
I like how the characters communicate with Ange, how Ange grew stronger and became more confident about herself throughout the series. She worked hard to save
the dying land and managed to convince the guys to become the 9 new guardians (in Kagayaki no Ashita). And how some of the guys falling in love with her. This will appeals to those who like romance genre.
Season 2(S2) is better than Season 1(S1). If you finished S1, you should watch S2, Kagayaki no Ashita. It would be a waste if you don't.
