I don't have 13league's patreon and so I can't read the progress reports, but as of May 5th, chap 9 of Nour's route was released (for patreon members only, obviously). There will be 10 chapters total and- if I remember correctly- an epilogue? Or maybe chap 10 is the epilogue?
Anyway, yeah, even if you can't see everything on there, it can be worth checking patreon if you don't see anything on the writer's blog. Not always, but sometimes.
