"Let the infection, begin....."
A mysterious, lethal disease is on the loose worldwide, resulting in a catastrophic death rate of humanity, and the increasing rise of attacks, caused by the living dead.
In Japan, several high school students and a school nurse have banded together to escape Fujimi High School shortly after it was attacked by zombies. The group now attempts to figure who or what was responsible for this plague, and in the meantime, attempt to survive the present apocalypse.
Its finally animated! WOOHOO! アニメの力~!
In my opinion, one the most realistic and apocalypse-state-world manga out there. Simply because I love zombie or an apocalypse world and Left 4 Dead series.
It's like a Left 4 Dead (huge fan!) anime but more focused on surviving an urban environment with an undead city against the protagonists.
