Takeda Shingen

Shingen is the leader of the Takeda House. He is the perfect warrior excelling in tactics, intelligence, and charisma. However, no one has ever seen the face beneath that mask.

The Truth
The perfect ruler Takeda Shingen is just an effigy, a hollow armor used as the "perfect" ruler of Takeda's territories.
