Takeda Shingen

Profile
Shingen is the leader of the Takeda House. He is the perfect warrior excelling in strength, tactics, intelligence, and charisma to the point where he is worshiped like a god by his people. However, no one has ever seen the face beneath that mask.

In truth, Takeda Shingen does not actually exist and is in fact simply a suit of armor worn in rotation by Takeda House's four lords. Each lord contributed one of his skills to make Shingen to make him appear as the perfect warrior and inspire hope in the people of Takeda. Once the guise is lifted, Takeda quickly falls.
