Play As Joe Musashi
Collect 40 Oboro Clan Coins during game play. Joe's sword damage does less than when playing as Hotsuma, however his shurikens are unlimited in number, do more damage, but do not stun. Also, since he does not use the Akujiki sword, his energy does not drain constantly.

The many faces of Shinobi
Hotsuma is one bad man, but he isn't the only available character. if you beat the game once and collect thirty talismans, his brother Moritsune will become available. Moritsune is stronger faster, and less hearty than Hotsuma, this means he kicks more ass, but Akujiki feeds of him more quickly. Finally, if you beat hard mode with forty talismans collected, you will unlock the OG, that's right, Joe Musashi himself. while he isn't as strong in sword play as the brothers, he can throw shurikens like no bodys business, enjoy trying to get these guys.
