Wait, since when is Ichigo immune to KS, the way i see it is that Gin describes KS's weakness as touching the blade before it is activated. However once you let go again you are vulnerable to KS again, thusly even though Ichigo touched KS that doesnt mean he isnt vulnerable to its illusions in the future.
