Young and inexperienced, he's only made it far due to the aid of his most loyal warrior, Tadakatsu Honda, also known as the greatest warrior that time has ever known (or so they all say).  Despite his youth, he's still willing to risk it all in the hopes of changing the world for the better.  

NOTE: The image I used depicts his attire during Season 1 and despite what they say about him getting killed before the finale of Season 1, he does come back & is a main protagonist for the Sengoku Basara movie which I hope to also parody.
