Who will prevail?
Location: The Forest of Death
Kinshiki possesses information concerning Itachi's abilities, disregarding Susano'o.
Condition: Itachi is restrained from utilizing the Sword of Totsuka.
Wait a minut here Kinshiki is a beast with elements(water, fire, earth, lightning and wind). But Itachi has the Yata mirror a shield wich repels all elemental attacks so most of Kinshikis attacks would be usless, Its a bad Match up for Kinshiki, and Itachi could just seal him with Totsuka.
