HOTD: Undead World

Sakata Rentaro's life was as normal as anyone's. Went to school, spent time with his friends. Life was good, but he always felt that something was missing, something exciting. And now, while accompanied by his friends, in the middle of a Zombiepocalypse, as he tried his best to survive, he wanted more than anything to go back... or did he?
