Two new high quality scans for Naruto Shippuden: Ultimate Ninja Storm Revolution from Shonen Gamez reveal more info about Shisui Uchiha, Itachi’s late-friend, including his gifts and his backstory.

Revolution will be featuring an exclusive animated short showcasing Shisui’s relationship with Itachi. Both scans are just below, so you can check them out.
