The Story Line
One Piece
One Piece has lots of adventures and the crew seldom stay in the same place for long. This enables it to introduce a massive collection of characters, some memorable, some forgotten. The series has tons of comical moments and the crew’s antics are always fun to watch, though it also has its tear-jerking moments from time to time, tackling sensitive issues that most everyone can relate to. No wonder it's the #1 ranked manga in the world!
Naruto
Naruto is set in a shinobi world, filled with awesome scenes and beautiful friendships. We also meet a variety of ninjas who bring unique skills to the table. Some clone themselves, some manipulate shadows, and some even reanimate the dead. Naruto teaches us that to be accepted by society, all we have to do is save the world.
