Fist of the Arhat is a combat style that relies on Jirobo's raw physical might and includes flashy, hard, but simple attacks. By carefully managing his weight and performing complex body movements, Jirobo puts his entire mass to use to break and crush the opponent. His natural monstrous strength sharply increases when the cursed seal is activated, and at the second level he is able to throw an opponent using Super Size Increase.
The style is based on strikes with different parts of the body: an upward knee strike, a shoulder strike, a straight palm thrust, upward and downward palm strikes, as well as a straight punch.
