Kiss of the Rose Princess

Since childhood, Anís Yamamoto has donned a chic black choker with a silver rose which, unbeknownst to her, is a talisman gifted by her father. However, now that she’s a freshman at Shoubi Academy, she considers the adornment more of a burden than a charm. Despite her countless attempts, she is unable to disengage it from her neck, drawing unwanted attention from her peers.
One fateful day, a bat-like creature collides with Anís, thrusting an exquisite red rose card into her possession whilst also causing her choker to disappear. Knowing that removing her choker has severe consequences, Anís frantically searches for it. In the process, she uncovers her true identity as the Rose Princess, responsible for presiding over the four Rose Knights; Kaede Higa, the Red Rose with offensive capabilities, Mitsuru Tenjou, the White Rose with defensive abilities, Seiran Asagi, the Blue Rose whose forte lies in alchemy, and Mutsuki Kurama, the Black Rose who specializes in discovery. All four boys are extremely popular amongst their peers, and through a kiss on their assigned cards, Anís can summon their magical prowess whenever required.
