Let's go save the world
Ten years ago, mysterious monsters began appearing all over the world. People collectively refer to them as zombies. Initially, they were thought to be simple mutations or an epidemic, but as research progressed, it was revealed that they are not mere biological entities. They are enemies of humanity, constantly swarming to destroy the world. This plot implements the game TDS. Characters other than Guest are addressed by their Rank + Alphabet. For example, if someone is a Captain, they are addressed as Captain Z.
