One Piece: I Am an Assassin

As an assassin in my previous life, I was extremely satisfied with my profession. Although the skin is thin and the blood is low, with the agility, all enemies can be killed in one blow without the need for two swords. Hiding in the dark and taking advantage of unprepared people to deal with the enemy safely. There is no more perfect profession than this... "Are you kidding me! What is an assassin?! As my grandson, you want to become a navy stronger than anyone else! Do you want to receive the iron fist of love!" This novel and its characters are purely fictitious.
