Apocalyptic Mutation: I Can Do Whatever I Want in Japan

(Cataclysm, zombies, instances, all kinds of professions) The bad news: the apocalypse has suddenly arrived. A zombie virus breaks out, mutations emerge, and after a torrential rain, people awaken to a variety of professions. The world becomes fraught with danger. The good news: I'm in Japan. As long as I have no morals, morals can't hold me back. (This story may be a little unhinged. It's purely a funny, feel-good power fantasy, with no suffering for the protagonist.)
