Ef: A Tale Of Memories & Melodies

On Christmas Eve, Hiro Hirono meets a girl named Miyako Miyamura as she chases down a purse snatcher. Later, Hiro finds out that Miyako attends the same school as he does, and the two start spending time together. This leaves Hiro's childhood friend, Kei Shindo, feeling left out, so she tries to compete with Miyako for Hiro's attention, forming a love triangle. Meanwhile, Renji Aso meets a girl named Chihiro Shindo at an abandoned train station. He soon learns that Chihiro has a form of amnesia that makes her memory last only 13 hours. He also discovers that Chihiro dreams of writing a novel, but her condition has kept her from ever achieving that dream. Renji then decides to help her make it come true.
