One Piece: Snakewood

Ges, a nobody who awoke after a zombie epidemic, is looking for a means to save humanity. But she needs a crew she can rely on; she can't do this by herself.

*****

The bulk of people have been killed by a virus that has engulfed the one-piece world. In its desperation, the world government has blamed women for the problem and has begun to execute and enslave them all, eradicating them as well. Ges, a random girl, awoke with no memory of her identity or whereabouts. She wanders around for a bit, thirsty, famished, and worn out. She will eventually meet both allies and foes. Now that many pirates have gone rogue and numerous terrible organizations have emerged, the world is very different. Additionally, the government is now more cruel than ever. Who is actually worse in the heat of the moment? Man or the undead? Ges will soon learn the truth. She represents humanity's last chance to save the world.
