I found that when i trying to unlock the secret node at E5 normal, I failed to get perfect S on node C and D, plus i failed to get No Damage on base air raid, but managed to get rank S on node A. Then I changed to easy modo, got perfect S on node C and D, and no damage on Air raid, haven't reach node A but secret node appeared !!!

So maybe we can unlock the secret node on lower difficulty first, then change back to higher difficulty.
