Final answer before logging off: Both of them never directly in contact with SR fist, all of the damage are secondary and received by the armor first (except the strangle, which directly held by absolute defense), not to mention the PIC is activated. They're lucky Absolute defense held, because their armor are wrecked after taking severe beatings.
If we take PIC into account, Rin and Cecilia blasted into ground by Maya, creating two meter into soil and unharmed. Ichika is even worse, creating a crater at least 1 meter deep and again, unharmed.
Problem is, Ichika doesn't wear ByakuShiki when he swim, similar to the bath scene, he also doesn't wore the bracelet in the beach.
Rule of funny or very thin justification, pick your poison.
