Senshi is a samurai with four hands, wearing a suit of armor that protects him from his enemies. He has a Daishō (meaning long sword and short sword), Heiwa and Hankustu (Heaven and Hell) that he uses to try and protect the peace. His other two hands are only used when he is disarmed, and he delivers hard blows to his opponent to knock them out.
A warrior filled with honor and loyalty, Senshi has respect to all, even his enemies. He is kind and merciful to everyone, even in battle, where he attempts to only strike his opponent late into battle where he has enough power to end it in one turn, to minimize the pain. He is loyal to the battle, and refuses to run away, even when at a clear disadvantage. He does not fear death, instead seeing it simply as a reason for him to train and learn more.
