Here are some ways to fight against semi-axiomatic Strength (this assumes that it's something along the lines of always stronger than you rather than transfinitely strong):
1.) Seek to deflect strikes, rather than to directly absorb the force of the blow. If it's less powerful than an atom bomb, then we can use Evening Sky. In Second Stage, we can attempt to phase through the force of individual blows to make things easier on us. A few other ways to deflect or block without our supernatural abilities: against thrusts, use our sword to push the offending blade/arm/claw to the side away from us; against overhand strikes, either hold our blade up at an oblique angle to form a ramp that their weapon will slide down OR maneuver our sword behind the blow to knock the trajectory off course; in general, interpose our sword at an angle such that the blow strikes the side of the blade/arm/claw, leaving us free to deal a grievous strike.
