One Piece - Survivals for the fittest

Chizuki was orphaned the same day she was born. Losing the person responsible for her chance at life.
She spent most of her free time reading, not knowing of the talent deep within her.

All of it changed however, with an explosion. Followed by several more.
The destruction of her... home? yet not a single memory remained.
But you have to lose something to gain something more, and thats exactly what happened.
Waking up in a hospital surrounded by marines and a man munching on... crackers.
Follow her journey in a world of pirates, marines and a never ending adventure.
Will she regain her memory and take revenge? Or will she even care? And who's voice does she keep hearing?

Be prepared for a lot of detail. I'm trying to make it as realistic as possible but at the same time, it's a fantasy world. It may be a little slow but please give it a try. Thanks.

The world of One piece does NOT belong to me it belongs to Oda.
Chizuki is my OC other than that most if not all charcters belong to Oda.
