Stuck on Melkor's realm

[Aether]

I'm getting really frustrated with random mechanics that get up getting locked behind other things with no indication as to what's locking you out.

I'm missing a character next to Erza, and I've talked to EVERY NPC in the game, at every stage of the day possible, nothing new is triggering. I suspect its something to do with a "fruit thief" but I suspect the game broke, because everyone elses storyline is complete, but I never did that one.

I also can't do Erza's storyline, as I've fully explored Melkor's realm, gone through both side portals PLUS the red portal to unlock new monsters, ♥♥♥♥♥♥ ALL the new monsters, and....still says I have to explore Melkor's realm.

When you did finish Melkpr's realm, you need to max out your stats and complete all the magic training at your house, when you meat new female character and get wounded by cursed dagger you go back to the Erzas location and click on the man statue to destroy the barrier.
Erza doesn't have any ending. When you complete melkor's realm and Ezra upgrading it you can have s e x with all the enemies and that's all. You can't free Ezra from it's location or something.

If you are talking about Ash character - it's not Ezras, it's main story line. You should check steam wolktrhoug guides to understand what you are missing, it's not that hard to find.
