I found Barajou No Kiss while searching for a reverse harem. While it does have some original qualities, this series does not escape from many of the dreadful romance cliches.

Story: (7)
Anis has a choker given to her by her father which she cannot take off. One day, though, she loses it and while searching for it she discovers she's the Dominion of the Rose Knights. The title includes 4 cards and the servitude of 4 boys, all of which go to her school. It's starts out rather basic and drags on a bit to reach its main plot, and even now at chapter 20 the plot is not exactly crystal clear. In between Shouto also manages to add idols, cross-dressing, and magic. So in many ways, it's your typical harem.

Art: (8)
The art style is distinctively Shouto's, which is somewhat different from the norm. Its lines are dark, thick and everything is rather pointy. It's not your traditional shoujo art, but a rather different style that after a while comes to appeal to you.

Character: (6)
This is sadly the worst part due to the fact that it's so full of stereotypes. We have the standard pretty boy that's not exactly what you think; the quiet and mysterious guy; the sweet, loyal, and devoted boy; and the stubborn and hot headed guy that's actually somewhat sweet. The heroine is a little interesting, she's not a complete pushover like every other girl out there, but that's about it.

Enjoyment: (7)
Despite all the typical characters and story, it's rather enjoyable. Shouto manages to make it a little interesting, even though most of the material she uses is rather over-used in shoujo and harem series.

Overall: (7)
It's reverse-harem, shoujo, and typical. But manages everything in a way to make it more tolerable and even more enjoyable than many other series.
