One Piece: The Bloodthirsty Witch

People call her the "Bloodthirsty Witch," yet they don't know that what she hates most is blood. A childhood spent as a test subject and endless assassin training had long since left her numb. Her blood-red eyes of reincarnation took away her last hope, plunging her into darkness. At last, weary of it all, she escaped the nightmare of her childhood. After fleeing hell, she met a boy as radiant as sunlight. Could he be her safe haven?

"Hey, Luffy, can you take me out to sea?"

"Then, can I be your first mate?"

"Sure!"

"Um... no matter what happens, will you protect me?"

"Of course!!"
