Dumping the first chapter of the ongoing Crest of the Stars manga, by YONEMURA Kouichirou. There are two tanks out, but I only have a mediocre digital rip of the first chapter right now.
Banner of the Stars got a new novel after 8 years, but translations (or OVA) never.
It's an adaptation of the novels, so unless they magically made progress in Banners I very much doubt it.
I wish the anime would continue but then again a lot of it would be Lafiel's brother who is surrounded by boring people. At least Lafiel and Jinto have Sobach and Atosuryua around all the time.
They definitely get closer and closer, but the most recent stuff has been more focused on the war than Lafiel/Jinto moments.
I would suggest checking the site again, then.
