Shinbuki, or Weapon of Mind, was a fighting skill that changed one’s energy into varies weapons. The summoned Shinbuki was much stronger than any ordinary weapon, thus the teaching was expended. Soma Kenichi, a stray, was able to summon Shinbuki by himself with no one to teach him. While Soma was chased by an unknown organization, he met a famous Master of Miyazaki, prompting him to know that he was a special one called Tensaiji.
