Condolences to Good

Another of the seven swordsmen, namely Kaori Sato, has defected from Kirigakure in search of the power he desires. He hopes to become an apprentice under the legendary Kisame Hoshigaki - in exchange he'll lend his skill to the Akatsuki. There's only one issue: his morals. Can he really cut his ties to Kirigakure and send his condolences to good? The chances seem slim.
