It's a japanese novel about a zombie apocalypse and the MC wins duals swords through a lottery system.
I really don't think is a JP novel..I might be wrong but you might refer to God and Devil World or Terror Infinity.Both CN.
I definitely remember it as a japanese novel. It used to be here on novelupdates but I can't find it anymore.
Ok.Tell us something about the story,MC or other characters.. There are levels,skills and more things like that?
Did you meant this one? http://www.novelupdates.com/series/sekai-ga-death-game-ni-natta-no-de-tanoshii-desu/
