## Description
It’s been two years since the mysterious disease “princess syndrome” had been made public. It affects young girls during puberty and the split personality-like symptoms range from mild to serious. In serious cases, she could become like a totally different person due to her wavering feelings and gain a special ability called ‘märchen’ which could cause great problems to those around her. To combat this problematic illness, all carriers (called ‘princesses’) were gathered at Saint Andersen Private School on the secluded island of Yumegashima. One day, a boy Yuuji came to the school. He was the ‘liar prince’ who could put a stop to their rampaging.
