That's accurate.

[quote=Kabensaal]It absorbs and reflects kinetic energy. So, the sword's energy would be suddenly brought to 0 and the energy would be redirected at him, of course over a larger area than a sword's edge. So, it would be more like a hammer blow than a sword cut.[/quote]

Only kinetic energy procs Mokuren's semblance.  Energy, whether fire, electricity, laser, or what have you, would go right through it.  The returned attack is also pure force in all situations, not an exact replication of the exact attack done.  For instance, a stab with a knife isn't very much kinetic force; it's lethality lies in its ability to pierce.  Plus, we confirmed that the output of reflected force doesn't have infinite range, so someone shooting bullets at her can exhaust her semblance without getting touched.
