Naruto: Ultimate Ninja Storm

For this trophy, you need to acquire 14 or more Ninja Handbooks. Ninja Handbooks are the ninjutsu found inside the treasure chests of the village. By obtaining these items, you can learn new ninjutsu to use in battle. Newly-learned ninjutsu can be equipped under "Customize" on the Character Select screen. Also, treasure chests may appear where they weren't before after completing certain story missions. Whenever you finished a mission, pay attention for any information that informs you of newly-appeared chests.

All treasure chests boxes are marked with a green dot on your map like this:

There is a total of 28 Ninja Handbooks throughout the game, but collecting 14 out of 28 of them will unlock this trophy. It's important to take note that you can only start working on this trophy after completing the Genin Training Arc. Once that arc has been completed, chests will start appearing around the village from that point forward just by completing more story related missions. Last of all, some of these Ninja Handbooks are story related as finding the very first 13 from the treasure chests will unlock the trophy. This means that new ninjutsu customization like Sasuke Uchiha's Chidori and Naruto Uzumaki's Rasengan will also count towards the 14 or more Ninja Handbooks acquired. The earliest you can unlock the trophy is by completing the Leaf Destruction Arc.
