Reborn in Japan, I had a younger sister named Sora. I thought I could follow the path of a plagiarist and live happily with my girlfriend, Shino Asada.
But when I woke up in the hospital beside Sora's bed, the world had changed.
Half the world's population had been infected by germs and turned into all kinds of monsters.
Zombies, Lickers, Shadow Barbies, Corrupted Tyrants, Wingless Evil Spirits, and more.
While I slept, a System called [Apocalyptic Red Alert] finished loading.
To protect what I want to protect in this broken world, I wield the System, build a base, become the Allied commander, and bring guns and cannons to the world!
P.S. The author has graduated from the underground.
