Natan rarely talks. He hunts rare monsters down. He protects the Princess, as he refers to Shania. And he shoots stuff up with his Gun-fu.
And he does this pretty well; his Soul Valet technique deals a fairly solid amount of damage, and if the enemy immunes wind he can also use his Evil Eye spell to deal additional damage. Hardly a stellar strategy, or innovative, but he's not here to show off; he's just trying to keep track of Shania.
