This might be a little bit late, but I am currently doing E-5 on easy difficulty  and it only took me a (perfect) S-rank on node I  in order to unlock the final boss on Z2. alas  I DID NOT have to get an S-rank at node H as well.

It probably was the difficulty, but may be worth keeping it in mind for those doing it on easy as I did.
