On September 29, 2012, the world will end. The majority of people did not believe in this internet rumour, but many were still apprehensive as the date approached. Kazuomi was not one of these people. To him, the most important thing is to protect his late best friend Touya’s younger sister Iri whose eyesight is close to blindness. She had mistaken him for her own brother since Touya’s death in a motorcycle accident two years ago. Later, his classmate Mikaeru enlisted him into her unofficial circle, the ’9.29 countermeasures group’, which investigates whether or not the rumours are true and plans ways to prevent the end of the world. September 29 is fast approaching. It is the date when Touya died, and also Iri’s birthday. [Edited from Hau~ Omochikaeri!]
