Soho Takuan
About
Takuan is known for his brute honesty and meticulously perceptive personality, which was sought after by monks, swordsmen, and politicians alike (such as Tokugawa Iemitsu and Go-Mizunoo).
Takuan's shared correspondence with Yagyū Munenori was captured in a treatise called "The Unfettered Mind." Takuan helps capture Takezo and later renames him as Miyamoto Musashi, setting him free to travel and evolve as a person.
