'Dumber and Dumber Humanity Gets' is the full title name, but that's too long. This story is about a seemingly ordinary girl who spends her free time killing people. The main group, you could call it, is part of a special side of society where they kill people, as a job, since humanity has grown dumb over the years, it is now 4006, and humanity is stupid as it could ever be. The new 'modern society' can't tell who has killed who and is just overall, dumb (hence the title.) Now, this story shows all the adventures of a 'killing group' through the killing society.
when a viruse breaks out and killer people but don't stay dead they turn into zombies now everybody is in danger and dead there's only one person that is alive from the outbreak and she trys to help what's left of the human race fight back.
