In Kanji Samurai, the player will meet a variety of unique sensei along the way. One of these is Mysterious Mountain Sensei, a strong, yet kind hearted warrior who lives in the mountains. After working for many masters, he has become a freelance warrior: people come to him to request aid in fighting demons or even to settle local disputes. He lives in the mountains, not out of a desire to be a hermit or to be mysterious, but because he loves how fresh the air is up there. When the player encounters him, he is laid back, kind, and willing to lend an ear. However, he warns the player he is not afraid to kill. He regales the player with stories of his past, suggesting that killing one to save the many is sometimes the only path to peace.
