OP Fanfic : journey to becoming strongest

A millitary vetaren got rebon as luffy, and he's enjoying his life as luffy in slighlty different onepiece world.

I am writing this for fun and to improve my english, and it's my first time writing fanfic/novel ,but i hope it will be atleast intersting.

This fanfic will follow the plot somewhat. It will be a harem fanfic.

DISCLAMIAR : I do not own one piece or any of it's character, It's belongs to it's rightful owner.
