「Introduction」

A sudden outbreak of an unknown virus has destroyed the entire world. Most of the people have turned into horrendous, blood-seeking zombies.

As I was trying to escape from a deadly attack by a zombie, I was miraculously saved by some strangers---five attractive boys. They've been concealing themselves safely in a school building with other survivors.

But is this place really safe for us? Can we all survive from this bizarre catastrophe?
