“You’re the master of this world!” With those words, Kaito was invited by his energetic turtle-toting underclassman Nicole to Seikai Academy’s student council room to join the star-crossing circle. All of the girls in that group are peculiar in their own way. Once every year, on the night of Tanabata, they gather to try to access ‘Karumaruka’. If they are successful, then they would be freed from their curses and their fear of the future.
