My name is Tsutsumi Mamoru and I have just recently been reunited with my childhood friend Makabe Akane that I have not seen in three years.

Standing on the roof of the school, she confesses to me her love and we seal our love to each other with a kiss.

But, all of a sudden zombies begin to overrun the city attacking anyone in sight. Within a matter of minutes they overran the school that both of them were standing on the roof of in the town.

At the same time Akane's father calls to tell them that a similar incident happened in the past due to the zombies being controlled by girls known as "Queens." He also explains the only way to stop the zombies is to defeat the "Queens" and where the evacuation is taking place for the survivors.

With this information in tow, we set out to escape the city by getting to the evacuation point in town.
