Bukkoware Sekai de Shinda Toki

As Shirabane was bitten by a zombie, he thought, "This is awesome!" His parents had disappeared, he couldn't go to high school, and he was constantly being chased by debt collectors; he was in despair. But somehow, he woke up, still conscious, but in the state of a zombie!? Well then, I'll go to the high school I couldn't go to, make some zombie friends, and enjoy my second life! But that fun time was short-lived, as he once again fell into despair. What will the young man find in this rotten world, and what will he leave behind when he dies again?
