I've tried comparing my damage to Kakashi clones, as well as to a sparring partner. It appears that Han's mystery does not remove the type-buff from Mei's barrier. Is this correct? I've seen the tooltip saying that barriers are not buffs; I was under the impression that Han removes the type-buff, but leaves the environmental change of the barrier alone.

On another note, does Han's mystery remove the buff that Gengetsu receives when there are edo tensei units on the field? I have done damage testing with this, and it seems it is not removed, but my conclusion might be due to simple variability in mystery and standard attack damage.

Thanks for the help.
