Forced to join a club, he discovers that they are all full, until he meets Ryuko Tachibana, a girl looking for a member for the Paper Club. A club dedicated to an almost forgotten tradition. Koji joins Ryuko, unaware that this club will open the doors to friendship, love, and a world where paper, despite being obsolete, can still be a treasure.
