#Zombie Sagashitemasu

Thirteen years have passed since the Red Day, when a virulent disease killed ninety percent of humanity and raised the dead as zombies that attack the living. Survivors abandoned the major cities and built smaller communities, while an entire new generation grew up with no memory of the world before its collapse.

Aki belongs to that generation, and what little she knows about her missing father is enough to keep her from giving up on him. She leaves her village with close friends Haru and Natsuki, only to discover how completely the outside world is surrounded by the danger their sheltered life kept away. After rescuing Yuu and Sakura and taking refuge in a home improvement store, the growing group begins a search that is no longer only about finding one man, but about understanding the world that ended before they could know it.
