There's a post 8 months ago that posted a road map for tobira that said tobira intermediate would be split and the first book would come out in July. Obviously that didn't happen. Then I was able to find that same roadmap but updated and it showed the book would be out in september. I'm trying to find this info to see if it's still accurate or if it got pushed back again. And if it is still coming september, since it's only a month away if there's a specific date it'll release and possibly a date available for pre order.
UPDATE: Was able to find the answer myself by randomly clicking on japanese words I didn't know. Currently it still just vaguely says "september". I sent an inquiry through their website about it. Hopefully I can get some information.
