Story:10
One piece has a great story.Yeah one piece is long but Oda-sensei
Use that as an advantage with great buildups great mysteries
In one piece we follow Monkey D. Luffy on his journey to find one piece
with obstacles on the way and hardships he goes through.

One piece characters are amazing with great development
and the most saddest of back stories.
