So you know how I mentioned a couple of days ago how Ouran ruined me for reverse harem manga forever? Well, that's only partially true. It's true that most of them can't compare to the humor and character writing there, but it's also true that a lot of them are simply mediocre like today's selection.
KISS OF THE ROSE PRINCESS (Barajo no Kiss), by Aya Shouto. First published in 2008 and first published in North America in 2014.
PLOT:
Ever since she was little, Anise Yamamoto had to obey one rule above all: she must never remove her rose choker or else she will face a terrible punishment. Then one day a strange bat falls from the sky and snatches it right off her throat, leaving behind four mysterious cards. Anise discovers that with a kiss, she can use these cards to summon four magical knights to serve her. It's a neat trick, but what is Anise meant to do with this power? More importantly, how is Anise going to get her choker back before her father comes back home?
