So... the fake roses put a whole town to sleep, Sleeping Beauty style, to draw Anise out and fight the real rose knights, only to have the whole thing be an elaborate set up by her father Schwarz so he could give an abridged version of "How I Met Your Mother" and then he gets captured by the Rose Society so this turns into a rescue mission. Also we find out that Anise and Mitsuru are related. Oh yeah, and the Arcana Cards and Demon Lord are still a thing... AND WHAT THE HELL IS GOING ON?!
So yeah, with as few spoilers as possible, this series starts off as a fairly standard magical reverse harem rom-com, only for someone to switch the tracks and send this ride so far off course that I don't even understand how we got from cultural festival shenanigans to occult science in the basement.
Is the romance even still the main plot?!
Oh, and there's a short extra that goes over the rose knight roster, so none of that here.
Overall, a good start that went WAY out there to the point I think I'm reading a different story.
This series has 9 volumes.
