Hello, so, I was actually waiting for the events count because I thought that I had maybe missed something but after checking on the wiki and the 'dreams' it looks like I should have everything to unlock Diakor. I really don't want to have to do the game once more, would it be possible to receive some help, please?
You shouldn't have to restart the game for anything unless you want to see things that go away as time progresses. The discord and the fanmade wiki said how to get to him. But he's something you need to progress through, Jar, Sep, Azlos, and some of Ran's content for. The scene counter in game is still being worked on. Patreons have something for it but it's not complete just yet.
