The Man Named Kisame

The man named Kisame uncovers a hidden threat: Kisame Hoshigaki, the Akatsuki swordsman, has infiltrated the island sanctuary concealed within Samehada, spying on the jinchuriki the war is being fought over. The episode reveals the enemy already inside the alliance's most secret stronghold — the shark-man gathering intelligence on Naruto and Bee for Tobi. The sanctuary's secrecy is already broken. It's the canon arc's tension turn, the revelation that the enemy has penetrated the one place the alliance believed safe, the war's reach extending into paradise.
