Hardening Qigong[1] (硬気功 Katakikou) is a psychic and martial arts technique that Tsuchiya utilises. It works by concentrating the qi inside one's body and using it to harden the limbs.[2] The user is also able to increase the power of their strikes by transferring qi to the target and destroying the target from the inside.[2]
